Section 1Introduction

OverviewThe Harmony power system provides 24 VDC block logic power (BLP) and 24 VDC field power (IFP) to Harmony devices in the Symphony Enterprise Management and Control System. The power system components mount on standard DIN rail. All the necessary AC filtering, transient protection, input volt-age monitoring, and output voltage monitoring circuitry are included with the various individual assemblies that are part of the complete power system.

The power system includes Harmony power supplies and the hardware needed for AC input distribution to each Harmony power supply, the DC output distribution from the power sup-plies, and alarm status monitoring. The main power system components that make up the Harmony power system include:

• Harmony power supplies (up to five). The power supplies provide 24 VDC and are available in two power ratings: 480 watts and 240 watts.

• AC input assembly. This assembly distributes AC input power to the power supplies.

• DC output assembly. This assembly distributes 24 VDC BLP and IFP power to Harmony devices and other power system assemblies.

• MMU power assembly. This assembly distributes 24 VDC power to module mounting units to power IEPDS01 power supplies. The IEPDS01 supply provides Harmony rack module power (i.e., 5 VDC, 15 VDC, and -15 VDC).

• Alarm assembly. This assembly provides 24 VDC to col-umn fans (P-HA-MSC-FAN11 and P-HA-MSC-FAN21), and monitors voltages, column fans, door fans, and the IEPDS01 supply.

The power system accepts both 120 VAC and 240 VAC input power.

Power DistributionFigure 2-1 shows the power distribution and alarm statuses for the Harmony power system. The power system accepts 120 VAC and 240 VAC input power. The AC input power to the power system can be provided by one source (single source) or two sources (dual source) depending on the system require-ments.

The power distribution scheme incorporates three separate 24 VDC busses needed for Harmony devices: BLP A, BLP B, and internal field power (IFP). One power supply is dedicated to the BLP A bus, while another power supply is dedicated to the BLP B bus. The IFP bus is generated from one or more power supplies connected in parallel providing power to the single isolated 24 VDC field power bus.

The power system provides 12 output connectors that allow 24 VDC power to be distributed directly to Harmony control unit devices such as the Harmony area controller (HAC), Har-mony network communications coupler (HNCC), and Harmony I/O blocks (i.e., block mounting columns). The HAC and HNCC devices require BLP power only, while I/O blocks require both BLP and IFP power. 24 VDC field power is also made available to power field and other cabinet devices.

The AC input assembly provides no fusing or transient protec-tion for a Harmony power supply. All fusing and transient pro-tection is provided by the Harmony power supply itself.

Dual Sources

When using dual AC input sources, AC input one is brought into the AC input assembly at connector P6 (Figs. 2-2 and 2-3). Input connector P6 provides power to output connector P1 through switch SW1, connector P3 through switch SW2, and connector P7 through fuse F1. AC input two is then brought into the AC input assembly at input connector P2. Input connector P2 provides power to output connector P4 through switch SW3, connector P5 through switch SW4, and connector P8 through switch SW5.

Single Source

When using a single AC input source, the AC input is brought into the AC input assembly at connector P6 (Figs. 2-2 and 2-3). Then AC input one power is transferred over to input connector P2 by externally wiring P2 to P9.

AC Input Assembly

Transient Suppressor

If Overvoltage Category II rating at 240 VAC is not sufficient for the Harmony system application, a transient suppressor can be installed between the AC mains terminal block or AC mains fuse assembly and the AC input assembly to achieve the desired overvoltage category rating (Fig. 2-5). Refer to Table 8-4 for the part number of a recommended transient suppressor.

The transient suppressor is an isolated package that can be mounted to any flat surface. Locate the suppressor between the input terminators and the AC input assembly.

Power Supply Options

When using one input power source, up to five power supplies can be used: BLP A, BLP B, and three IFP power supplies. In this case, all power supplies connected receive input power from this one source.

When using two input power sources to achieve redundancy, up to four power supplies can be used: BLP A, BLP B, and two IFP power supplies. In this case, the BLP A power supply and one IFP power supply use AC input one, and the BLP B power supply and the second IFP power supply use AC input two.

Refer to Power SuppliesPower SuppliesPower SuppliesPower Supplies in this section for additional informa-tion.

AC Output

Cables connect AC power from output connectors P1, P3, P4, P5, and P8 of the AC input assembly to each power supply

(Figs. 2-2 and 2-3). Separate on/off switches SW1 through SW5 allow individually toggling power to each power supply. Refer to Table 1-5 for switch power ratings.

Door Fan Power

The AC input assembly provides 120 VAC or 240 VAC power to the enclosure door fan from connector P7. This power is sup-plied by AC input one on connector P6. Fuse F1 provides over-current protection for connector P6.

NOTE: The door fan must be rated for division 2, hazardous locations.

For a 240 VAC powered fan, fuse F1 provides overcurrent pro-tection for line one (L1) only. It is recommended that an exter-nal fuse be placed between the line two (L2) input and the door fan. Refer to Table 8-4 for the part number of a recommended fused terminal block that can be used to provide the external fusing.

Ground

The cover plate on the AC input assembly is a ground panel that makes the common earth ground connection for AC input one (P6) and AC input two (P2). The ground panel also makes the earth ground connection for switches SW1 through SW5.

Power SuppliesThe 24 VDC power supplies come in two different power rat-ings: 480 watt and 240 watt. The power system supports five power supplies, two designated for BLP power and three for IFP power. On the input side, the power supplies provide:

• Full isolation, input to output.• Power factor correction.• Transient protection.• Input filtering.• Hot-swap capability.• Input over and under voltage protection.

On the output side, the power supplies provide:

• Short circuit protection.• Overload protection.

2 - 8 WBPEEUI210508A0

DC Output Assembly

• No minimum load requirement.• Current share capabilities.

NOTES: 1. Power supplies are ordered separately. Refer to Table 8-2 for part num-bers.

2. When using dual AC input sources, two supplies are powered from AC input one and two are powered from AC input two.

Using single or dual AC input sources and the individual power supply output power ratings affect the maximum num-ber of power supplies. Table 2-2 lists some valid power supply configurations for a single Harmony power system.

DC Output AssemblyThe DC output assembly shown in Figure 2-6 distributes 24 VDC power to various power system devices and to various Harmony control unit devices. The assembly supports 12 DC output connections.

Figure 2-7 is a simplified schematic diagram of the DC output assembly. The assembly has three isolated 24 VDC power buses: BLP A, BLP B, and IFP. Also, fused 24 VDC field power is available at 14 terminal blocks on the assembly.

DC Output Assembly

Block Logic Power

BLP A power connects to the DC output assembly at input connector P19 and BLP B power connects to the DC output assembly at input connector P20. Cables connect the BLP power between the DC output assembly and the BLP A and BLP B power supplies. The maximum total current drawn through connectors P19 and P20 is not to exceed 20 amperes or 480 watts each.

BLP A power is available on pin one and BLP B power is avail-able on pin two of output connectors P1 through P12 (Fig. 2-7). The BLP A and BLP B busses share a common return path, block logic common (BLC). This BLC common is available on pins three and four of output connectors P1 through P12.

Internal Field Power

IFP power connects to the DC output assembly at input con-nectors P21, P22, and P23. Cables connect the IFP power between the DC output assembly and the IFP power supplies. The total current drawn through these connectors cannot exceed 20 amperes or 480 watts. The DC output assembly diode auctioneers (i.e., ORs) the 24 VDC outputs of the IFP power supplies into one common IFP bus.

IFP power is available on pins seven and eight of output con-nectors P1 through P12 (Fig. 2-7). The common return for IFP is internal field bus common (IFC). This IFC common is avail-able on pins five and six of output connectors P1 through P12.

24 VDC Field Power

The DC output assembly provides fused 24 VDC field power for external device connection. It has two banks of seven con-nectors: bank one P36 and bank two P37 (Fig. 2-6). The field power is derived from the IFP power supplies. The total maxi-mum current drawn through each bank of field power connec-tors cannot exceed 15 amperes. Each connector will accept up to 3.3 square-millimeter (12 AWG) wire.

DC Output Assembly

WBPEEUI210508A0 2 - 11

DC Common

Grounding issues must be considered at the system level and are not discussed in detail in this instruction. Refer to the Site Planning instruction for system grounding information and considerations.

Connector P35 provides a common reference point for the BLC and IFC commons (Fig. 2-7). This is the only location in the enclosure where both the BLC and IFC commons are con-nected. In a single enclosure system, this point should be tied to a cabinet earth ground stud. In a multibay enclosure, DC common connections (P35) for all DC output assemblies within the enclosure must be daisy-chained together using 3.3 square-millimeter (12 AWG) wire, then tied to a cabinet earth ground stud at one location.

In Harmony systems that have module mounting units (MMU) with Harmony rack modules, the MCOM and I/O COM on the MMU backplane must be connected to DC common on the DC output assembly using 3.3 square-millimeter (12 AWG) wire.

Alarm Outputs

The alarm outputs at output connector P33 shown in Figure 2-7 are used to monitor the BLP A voltage level at con-nector P19, BLP B voltage level at connector P20, and IFP volt-age levels at connectors P21, P22, and P23. If any of these voltage levels drop below 21.6 VDC, the alarm assembly will activate an alarm signal. Refer to Alarm AssemblyAlarm AssemblyAlarm AssemblyAlarm Assembly in this sec-tion for further explanation.

Short Circuit Protection

All Harmony power supplies have short circuit and overvoltage protection on their outputs. The DC output assembly does not provide any additional protection for the power supplies that are connected to it. The assembly does, however, have protec-tion for the IFP auctioneering diodes. A transient voltage sup-pressor is included to insure that the IFP bus never exceeds 45.7 VDC if a transient fault occurs.

2 - 12 WBPEEUI210508A0

MMU Power Assembly

MMU Power AssemblyThe Harmony power system provides 24 VDC power to the module mounting unit for Harmony rack module power. This power is then used by a rack-mounted IEPDS01 power supply to develop the 5 VDC, 15 VDC, and -15 VDC voltages required by rack modules. Refer to Appendix B and the DC Modular DC Modular DC Modular DC Modular Power SystemPower SystemPower SystemPower System instruction for additional IEPDS01 information.

NOTE: Do not use the 24 VDC output of the MMU power assembly as field power for any other type of external device.

The MMU power assembly shown in Figure 2-8 distributes the 24 VDC power to the module mounting units. The MMU power assembly supports two module mounting units each with its own connection point on the assembly. Figure 2-9 is a simpli-fied schematic diagram of the MMU power assembly.

A cable connects BLP A and BLP B power from any one of out-put connectors P1 through P12 on the DC output assembly to input connector P3 on the MMU power assembly. The MMU power assembly diode auctioneers (i.e., ORs) the DC output assembly 24 VDC outputs into one common 24 VDC bus. This

24 VDC bus is connected to pin one of connectors P1 and P2. BLC common is connected to pin two of these connectors. The connection between the MMU power assembly (P1-1, P1-2 or P2-1, P2-2) and the MMU backplane (P39 and P40) is wired using 3.3 square-millimeter (12 AWG) wire.

Alarm AssemblyThe alarm assembly shown in Figure 2-10 performs the follow-ing functions:

• Provides 24 VDC power to column fans.• Monitors column fan status.• Monitors voltages on the DC output assembly.• Monitors enclosure door fans.• Provides 5 VDC power to door fan status circuitry.• Monitors the IEPDS01 power supply status.

Figure 2-11 is a simplified functional block diagram of the alarm assembly. The alarm assembly receives its power from the DC output assembly. A cable connects BLP A, BLP B, and IFP power and the BLC and IFC commons from the DC output assembly to the alarm assembly at input connector P12. BLP A and BLP B are fused and diode auctioneered (i.e., ORed) on the alarm assembly.

The column fan power and column fan monitoring circuitry is powered by IFP power. The voltage (BLP/IFP) monitoring, door fan monitoring, and the auxiliary power supply (i.e., IEPDS01 power supply) monitoring circuitry is powered by 5 VDC devel-oped onboard the assembly. An onboard voltage regulator develops the 5 VDC from a single diode auctioneered 24 VDC. BLP A and BLP B power supplies provide the 24 VDC in this case.

Alarm Assembly

The monitoring circuits on the alarm assembly have jumpers to enable or disable their function. The jumpers affect column fan status, voltage, and door fan status monitoring.

The alarm assembly has fusing to protect the bus voltages that power the monitoring and alarm circuitry. Fuses F9 and F10 provide protection for the BLP A and BLP B power while fuses F1 through F8 protect the IFP power for the column fans.

Status Output Alarm

If any device being monitored by the alarm assembly fails, the alarm assembly will warn the system operator by pulling the 5 VDC status output alarm (SOA) signal to a low logic level (0 VDC). A Harmony controller monitors the SOA signal line and will communicate this alarm to the rest of the system over Control Network (Cnet). Once sent on Cnet it can be seen on a human system interface. The SOA signal allows tracing a

problem to a particular enclosure. The assembly connects to the SOA lines (SOA 1 and SOA 2) at connectors P1 and P2.

Voltage (BLP/IFP) Status

The alarm assembly monitors the BLP A and BLP B power supplies and the individual power supplies providing the IFP power. The voltages that the alarm assembly monitors enter the alarm assembly at input connector P23. The alarm assem-bly monitors these voltages for low levels only.

The voltage monitor circuit is a basic non inverting compara-tor. If any of the power supply voltages fall below 21.6 VDC, the alarm assembly will recognize this as a bad power supply status and alert the system using the SOA signal. In order for the status to return to a good state, the power supply voltage must rise above 24 VDC.

Alarm Assembly

The voltage monitoring circuits on the alarm assembly also provide LEDs to help recognize which power supply is bad (refer to PPPPower System LEDsower System LEDsower System LEDsower System LEDs in Section 4). Each power supply has an LED that indicates good or bad output status.

Column Fan Power and Status

The alarm assembly provides IFP power for up to eight nonre-dundant column fans (P-HA-MSC-FAN11) or four redundant column fans (P-HA-MSC-FAN21). A nonredundant column fan contains two 24 VDC fans and a redundant column fan con-tains four 24 VDC fans. A single six conductor cable connects power and status for each pair of fans in the column fan assembly. The nonredundant column fan assembly uses one cable and one connection point while the redundant column fan assembly uses two cables and two connection points on the alarm assembly. Refer to the Block Power and Mounting Hardware instruction for a complete description of the col-umn fans.

Each pair of fans in a column fan assembly is powered in par-allel from one connector. Both positive (+) lead wires and both negative (-) lead wires from a pair of fans connect at the posi-tive and negative terminals on the alarm assembly. Each fan, however, has its own status line.

The fan status signal is an open-collector, low true signal. Its return is the negative (-) power input or IFC common. The fan status circuitry monitors each of the fan status lines and as long as the status lines remain at a low logic level, the fan is considered good. If the status line rises to a high logic level, the alarm assembly will recognize this as bad fan status and alert the system using the SOA signal.

In order to help identify which fan in the column fan assembly is causing a problem, the monitoring circuitry provides each status line with its own LED labeled A1 and A2 (refer to PPPPower ower ower ower System LEDsSystem LEDsSystem LEDsSystem LEDs in Section 4).

Door Fan Status

The alarm assembly can monitor two enclosure door fans. Each enclosure door fan has a hall-effect circuit that returns a pulse-train signal for the alarm assembly to monitor. The door fan returns one pulse per second if the fan assembly is func-

Mounting

WBPEEUI210508A0 2 - 17

tioning properly. If the pulses from the door fan stop, the alarm assembly will recognize this as a bad door fan status and alert the system using the SOA signal.

The door fan status circuitry also provides LEDs to help iden-tify which door fan is bad (refer to PPPPower System LEDsower System LEDsower System LEDsower System LEDs in Section 4).

MMU Power Status

The IEPDS01 supplies connect their status output pins to a common status bus on the MMU backplane. This internal sta-tus bus is available at connector P41 on the MMU backplane (located on the back of the module mounting unit). The com-mon return for the status bus on the MMU backplane is I/O COM (connector P42) tied to DC common.

The auxiliary power supply status circuitry does notnotnotnot have an associated LED. The IEPDS01 power supply in the module mounting unit has an LED on its front panel that indicates good or bad output status.

MountingAll Harmony power system assemblies except the power sup-plies come already attached to the power system mounting panels when ordered using the P-HA-HPS-KIT nomenclature (Table 8-1). Figure 2-12 shows the standard locations for the various assemblies on the mounting panel. Because the differ-ent assemblies, except the power supplies, use DIN-rail mounting, assemblies can be easily rearranged from this stan-dard configuration.

The mounting panel is intended for standard 800-millimeter (31.5-inch) enclosures. The mounting panel has mounting holes that accommodate either 762-millimeter (30-inch) or 483-millimeter (19-inch) and side rails.

CoolingThe Harmony power system does not require any cooling fans for internal enclosure temperatures up to 60° C (140° F). Cool-ing accessories such as door fans are required if internal tem-peratures exceed 60° C (140° F).

Section 5Troubleshooting

IntroductionThis section provides troubleshooting information necessary to isolate Harmony power system problems. It is not meant to be all inclusive. If a problem exists that cannot be corrected using the information provided in this instruction, contact a local ABB service office for assistance.

Status IndicationsTroubleshooting of the Harmony power system is performed mainly by observing LED indications. The alarm assembly pro-vides LED indications for the BLP power, IFP power, column fans, and door fans. Power supplies also have good/bad status LEDs. Refer to Alarm AssemblyAlarm AssemblyAlarm AssemblyAlarm Assembly in Section 2 for additional information.

Table 5-1 summarizes the bad status indications for the alarm summary and provides some corrective actions.

SOA Alarm

SOA Alarm

The alarm assembly can monitor and report a problem with BLP power, IFP power, a column fan, and additionally MMU power within a single Harmony control unit (HCU) by activat-ing an SOA alarm. This assumes the monitoring circuitry has been enabled and status signals have been properly connected to the assembly. Refer to Status Output AlarmStatus Output AlarmStatus Output AlarmStatus Output Alarm in Section 2 for additional information.

The SOA signal line is monitored by a Harmony controller. SOA status reported to the system by the controller provides a means to narrow a problem down to a specific HCU cabinet. After the specific HCU cabinet with a problem has been identi-fied, LED indications can be observed to further narrow the problem down.

NOTE: If there is an active SOA alarm and the alarm assembly does not show any bad status, check the IEPDS01 power supply located in a monitored mod-ule mounting unit. Also, other Harmony devices such as Harmony controllers and Harmony blocks can activate an SOA alarm for local power problems.

Section 6Maintenance

IntroductionThe reliability of any stand-alone product or control system is affected by the maintenance of the equipment. ABB Automa-tion recommends that all equipment users practice a preven-tive maintenance program that will keep the equipment operating at an optimum level.

This section presents procedures that can be performed on-site. These preventive maintenance procedures should be used as guidelines to assist in establishing good preventive maintenance practices. Select the minimum steps required to meet the cleaning needs of your system.

Personnel responsible for maintenance should be familiar with the Harmony power system, have experience working with pro-cess control systems, and know what precautions to take when working on live AC systems.

Preventive Maintenance ScheduleTable 6-1 is the preventive maintenance schedule for the Har-mony power system. The table lists the preventive mainte-nance tasks in groups according to their specified maintenance interval. Some tasks in Table 6-1 are intuitive or self explanatory. Instructions for tasks that require further explanation are covered in the indicated procedure section.

NOTE: The preventive maintenance schedule is for general purposes only. Your application may require special attention.

Section 7Repair and Replacement

IntroductionThis section explains repair and replacement procedures for individual Harmony power system assemblies.

RepairPower system repair is limited to assembly replacement. If an assembly fails, remove and replace it with another. Do notnotnotnot attempt to replace discrete components in any Harmony sys-tem device.

Replacement

The replacement procedures for most parts and assemblies are intuitive. Figure 7-1 is the Harmony power system assembly replacement flowchart, which contains replacement proce-dures for those parts and assemblies that need explanation.

In the flowchart, each flowchart block represents a single task. The PR code in the flowchart block identifies the procedure section that describes the steps to complete the indicated task. Some steps are self-explanatory and have no related procedure section. Complete all steps given in a procedure section before continuing to the next flowchart block. The procedure sections are located towards the back of the instruction.

Important Be sure all cables and wiring are clearly marked before remov-ing them from any assembly so they can be easily reattached. If necessary refer to the appropriate cable connection and wir-ing procedure sections.

WARNING

Verify the cabinet AC power is turned off at the AC mains dis-connect or the AC power is turned off using the AC input assembly switches as indicated in the replacement flowchart before starting the replacement procedure. Failure to do so could result in severe or fatal shock. Do not turn the power on until the replacement procedure is complete.

Appendix BIEPDS01 Power Supply

IntroductionThe IEPDS01 power supply module receives 24 VDC input power from the module mounting unit (MMU) backplane. DC-to-DC converters develop the regulated output voltages of 5 VDC, 15 VDC, -15 VDC, and 24 VDC. These voltages are available at the MMU backplane for distribution to Harmony rack modules. Refer to the DC Modular Power SystemDC Modular Power SystemDC Modular Power SystemDC Modular Power System instruc-tion for complete information.

InstallationThe IEPDS01 power module mounts directly in the module mounting unit. Any slot except the right-most slot (slot 12) can be used. Figure B-1 shows the power supply jumper and fuse locations. Table B-1 describes the IEPDS01 jumper settings. Verify a 10 ampere, 125 volt fuse is present in fuse holder F1. Refer to Table 8-4 for the fuse part number.

NOTE: For optimum heat dissipation and power distribution, do not exceed more than two IEPDS01 modules in any module mounting unit.
