Remote Annunciator

ANNUNCIATOR DESCRIPTIONThe remote annunciator is available in the following versions:

0G5719 - Remote Annunciator has both relays and LEDs/Keypad (RRP & RAP)0G5720 - RRP version - Remote Relay Panel (Relays with no LEDs/Keypad)0G5721 - RAP version - Remote Annunciator Panel (LED's/Keypad without relays J1 - J8)

The Remote Annunciator provides remote monitoring and annuncia-tion of up to 18 generator parameters using the lights/LEDs located on the annunciator keypad. Selected generator parameters can be annunciated using the eight Form A relays provided on 0G5719 and 0G5720.The Remote Annunciator also provides two system-level warnings which are System Ready and Communications OK. Multiple annun-ciators can also be connected to obtain remote monitoring and annun-ciation of all 18 generator parameters. Power to the remote annuncia-tor is supplied from the generator battery (+12VDC or +24VDC).Communication with the Remote Annunciator is via a RS485 serial data link. The remote annunciator is typically configured for listen only mode (also called slave or passive mode). In this operating mode, the annunciator receives information on the generator status, from the generator controller and activates/deactivates the relay outputs to reflect the status of up to eight selected generator parameters. The remote annunciator can also be configured to request status informa-tion from the generator (called master or active mode).

The specific faults to be annunciated using the relay outputs (J1 - J8) can be selected using either the DIP switches located on the annunciator printed circuit board, or the Graphical User Interface (GUI) available using a computer via the RS232 connector on the annunciator printed circuit board (see Figure 2).Relays J1 - J8 provides a set of normally open contacts. All relays are energized (contacts closed) when power is applied to the annuncia-tor. The relay selected to annunciate a particular fault will then open during a fault.The terminal block connections (J10), used to connect the battery supply and the RS485 communication lines to the remote annunciator are shown in Figure 1. The location of DIP switches S1, S2, S3 and S4 and the RS232 connector are shown in Figure 2.

INSTALLATION AND MOUNTINGNOTE:

3. For ALL models installation must always com-ply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, the generator and related components must be installed completely in conformance with the manufacturer’s instructions and recommenda-tions. Following proper installation, do nothing that might alter a safe installation and render the unit in non-compliance with such codes, stan-dards, laws and regulations.

4. The plastic knockout that is used to route the wires and cables into the annunciator should be removed with the annunciator firmly supported by placing it on a flat surface.

5. Wire tie-downs are provided in two places on the base of the annunciator to provide strain-relief for the connecting cables and wires (Figure 3).

RELAY ANNUNCIATION (J1 - J8)The user can select up to eight of the following 18 generator param-eters to annunciate via the relays, when the 10 position (S1) and the 8 position (S2) DIP switches on the annunciator PCB are being used.

PARAMETER "GENERATOR RUN"This parameter is defined as any one or more generators in the system running.

PARAMETER "GENERATOR POWER"This light/LED indicates different things depending on the type of system it is attached to.

It is defined as whether the Transfer Switch is in the Generator Supply Position.For a PowerManager System Controller (PM-SC with external transfer switch(es)), generator power is defined as any one or more generators in the system running and connected to the generator bus.For a non-paralleling engine controller (PM-GC WITHOUT internal transfer switch), it represents the status of input 4 (TB2-5) to the generator controller. This should be connected to the generator side auxiliary contact of the external transfer switch. A closure to ground will cause the light to illuminate. This shows whether the load is powered by the generator.For an engine controller that is part of an MPS system, generator power represents the state of the internal contactor that the gen-erator is connected to.

PARAMETER "LINE POWER"This light/LED indicates different things depending on the type of system it is attached to.

Is defined as whether the Transfer Switch is in the Utility Supply Position.For a Power Manager System Controller (PM-SC with external transfer switch(es)), line power represents the auxiliary input C (TB6-4).For a non-paralleling engine controller (PM-GC WITHOUT internal transfer switch), it represents the status of input 3 (TB2-4) to the generator controller. This should be connected to the utility side auxiliary contact of the external transfer switch. A closure to ground will cause the light to turn ON. This shows whether the load is power by the utility.For an engine controller that is part of an MPS system, line power is not used.

PARAMETER “BATTERY CHARGER AC FAILURE”This light/LED annunciates upon loss of 120VAC power supply to the battery charger and is communicated to the Annunciator by the generator controller.

GENERATOR STOP INDICATORSThese lights/LEDs will flash when any alarm occurs and the horn will sound as follows:

Annunciator Light Light Color Audible Alarm

RPM Sensor Loss Red Yes

Overcrank Red Yes

Overspeed Red Yes

Low Oil Pressure Red Yes

High Water Temp Red Yes

Low Water Level Red Yes

Emergency Stop Red Yes

NOTE:7. Both the High Water Temp and the Low Water

Level LEDs will turn ON if either fault condition is present.

The "Re-arm Horn" switch can be used to turn off and re-arm the horn, or the alarms can be fully acknowledged using the "Reset" switch.The "Reset" switch will turn off and re-arm the horn, and any flashing lights will switch to the ON state until the alarms are no longer present at the generator control panel.

NOTE:

8. The alarm condition must be reset at the generator control panel.

9. When this annunciator is used in a Modular Power System (MPS), an alarm on any one of the genera-tors will cause the lights/LEDs to light, and alarms to sound.

WARNING INDICATORSThese lights/LEDs will flash when any alarm occurs and the horn will sound according to the following table:

Annunciator Light Light Color Audible Alarm

Latched

Pre-low Oil Pressure Yellow Yes Yes

Pre-high Water Temp Yellow Yes Yes

Pre-low Water Temp Yellow Yes Yes

Pre-low Fuel Yellow Yes Yes

Battery Charger AC Failure

Yellow Yes No

Low Battery Voltage Yellow Yes No

High Battery Voltage Yellow No No

Generator Run Yellow No No

Generator Power Yellow No No

Not in Auto Red Yes No

Remote Annunciator

These alarms will be latched/not latched by the annunciator accord-ing to the above table. They can be acknowledged at the annunciator using the ‘Reset' switch—the active lamps will then stop flashing and remain in the ON state until the alarm signal clears from the genera-tor control panel. The "Reset" switch will also turn off and re-arm the horn.

NOTE:

10. These lights can only be fully reset when the alarm state is no longer active and “Reset” has been pressed at both the generator control panel and the remote annunciator. Alternatively, at any time the horn can be turned OFF and re-armed with the "Re-Arm Horn" switch.

11. When this annunciator is used in a Modular Power System (MPS), a warning on any one of the generators will cause the above lights to light, and alarm to sound (if the warning is audi-ble).

SPARE INDICATORThe spare indicator light/LED can be activated from the PM-GC or PM-SC by using the Integrated Logic Controller (ILC) feature in the G-panel or H-panel. Also see the section in this manual describing the operation and set-up of the spare keypad switch.

Annunciator Light Light Color Audible Alarm

System Ready Green Yes

Communication OK Green Yes

Line Power Green No

Spare Green No

SYSTEM STATUS INDICATORSThese lights/LEDs are for Status indication only—the normal condi-tion is ON.

SYSTEM READYThe System Ready is defined as ALL “in service” generators are ready to start, run, and supply power. Any generators manually declared as “out of service” will not affect this LED.Upon a loss of System Ready, the annunciator will respond as fol-lows:1. The System Ready LED will begin to flash.2. The alarm will sound.The “Re-arm Horn” switch can be used to turn off and re-arm the horn, or the alarm can be fully acknowledged using the reset switch at which time the System Ready LED will turn off and remain off until the System Ready status is returned.

COMMUNICATION OKThis LED will be ON as long as there is proper communication between the Remote Annunciator Panel and the Generator control system. It typically requires less than a minute for the Annunciator to determine the correct baud rate and connect to the RS485 bus.When communication failure occurs, the Annunciator will flash the communication LED, and sound the horn. The rate of flashing will be indicative of the cause of error.1. No reply from the generator control system, Frequency = one

second ON/one second OFF2. Consecutive data errors, Frequency = 0.5 second ON/two sec-

onds OFF.This alarm condition can be acknowledged at the Annunciator using the “reset” switch - the horn will be turned off and re-armed, and the communication OK light will continue to flash until proper communica-tion returns.

SYSTEM KEYPAD SWITCHESTEST SWITCH

While the test switch is pressed, all lights/LEDs will light and the horn will sound. When released the lights/LEDs will return to their original status. During this test, communication to the generator control sys-tem will be suspended.

RE-ARM HORN SWITCHThe re-arm horn switch will silence the alarm horn and re-arm it for new alarm occurrences.

RESET SWITCHThe reset switch is used to acknowledge any active alarms. It will re-set any flashing light/LED’s to a ON (steady) condition (or OFF for normally on lights). If the alarm no longer exists and it has also been latched OFF at the generator control panel (pre-alarm indicators only) the active light will go OFF. It will also silence the horn and re-arm it for new occurrences.

NOTE:

12. Pre-alarm conditions MUST be reset at the gen-erator set control panel.

SPARE KEYPAD SWITCHWhen DIP Switch S3, Position 4, is in the ON position, it allows the SPARE Keypad Switch to control Relay 8. When this DIP switch is in the ON position, pushing the SPARE keypad Switch will energize Relay 8 and turn on the spare light/LED on the keypad. Pushing the SPARE keypad Switch again will de-energize Relay 8 and turn off the spare light/LED.

Remote Annunciator

NOTE:

13. The Remote Start capability using the Spare Keypad Switch and Relay 8 is only available when Remote Annunciator version P/N 0G5719 is used.

OTHER FUNCTIONS GRAPHICAL USER INTERFACE (GUI) OR DIP SWITCHES ENABLED - DIP SWITCH S3-1

When Position 1 is in the ON position the Graphical User Interface (GUI) must be used to set the relay fault conditions. When Position 1 is in the OFF position the DIP switches on the Annunciator control board must be used to set the relay fault conditions.

MASTER/SLAVE MODE - DIP SWITCH S3-3Position 3 is used to configure the Annunciator as either a Slave (OFF position) or as a Master (ON position). In Slave mode, it is a Modbus slave and must be connected to a master port on the PM-GC or PM-SC. This method allows for the connection of more than one Annunciator. In Master mode, the Annunciator is the Modbus master and will request data from the PM-GC or PM-SC. The PM-GC or PM-SC must be set as a slave port when the Annunciator is configured as the Master (Figures 10 and 11).

SPARE KEYPAD SWITCH - DIP SWITCH S3-4Position 4, when it is in the ON position, it allows the SPARE Keypad Switch to control Relay 8. When this DIP switch is in the ON position, pushing the SPARE keypad Switch will energize Relay 8 and turn on the spare LED on the keypad. Pushing the SPARE keypad Switch again will de-energize Relay 8 and turn off the SPARE LED. This fea-ture can be used to implement a Remote Start function. This Remote Start feature is only available with the Remote Annunciator version (0G5719) that has both the Relays and the Keypad.

BAUD RATE SELECTION (DIP SWITCH S4)DIP Switch S4 can be used to set the Communications Baud Rate to a pre-determined value (see table).

ALARM RELAY (J9)The Annunciator provides a relay with both a Normally Open contact and a Normally Closed contact. This relay is energized when DC power is provided to the Annunciator so that in the event power to the Annunciator fails the relay contacts will change state. When the Audible alarm is activated this relay will be de-energized.

RS485 LINE TERMINATION RESISTOR A 1000 ohm RS485 terminating resistor is installed on the Remote Annunciator PC board via a 3-position jumper (JMP1 in Figure 2). In most applications this 1000 ohm terminating resistor is connected and the jumper (JMP1) is in the closed or 1-2 position. This jumper can also be moved to the open or 2-3 position.

GRAPHICAL USER INTERFACE (GUI)A DB9 connector is provided on the Annunciator Control Board for use in setting the Annunciator functions. A Generac GenLink serial cable (P/N 0F7707) should be used to connect a laptop computer’s RS232 serial port to the Annunciator DB9 connector. The GenLink cable is a Null-Modem style serial cable with female-to-female DB9 connectors. Shown in Figure 12 is a typical Windows GUI interface as it appears on the computer display.

RS485 COMMUNICATIONSIn a typical application, the Annunciator monitors (i.e. slave mode) the Generator control system via the RS485 communication line.

SERIAL INTERFACEBaud Rate Auto-Detect 57.6K, 38.4K, 9600

or 4800 (No Parity, 2 Stop Bits)

COMMUNICATIONS CONNECT TIMEWhen an Annunciator is powered up onto an existing RS485 network, there will be a period of time, during which the unit may report a “communication failure”. During this time the Annunciator is searching for the correct Baud rate. The Annunciator will typically communicate within one minute after being connected.

ERROR HANDLINGAn error will be reported by flashing the Communication OK light—the rate of flashing will be indicative of the cause of the error.1. No reply from generator control system—frequency one second

on/one second off.2. Consecutive data errors—frequency 0.5 seconds on/two seconds

off.The Annunciator, if configured for auto-baud rate detect, will try sev-eral times at each of four different baud rates (57.6K, 38.4K, 9600 and 4800) before reporting a communication error by de-energizing all the relays and then flashing the Communication OK light.

LIMITS OF OPERATIONThe following communication restrictions apply for multiple units on a common RS485 line:

A maximum of 15, 1000 ohm RS485 Loads (i.e. 57.6K Annunciator, G-panel, H-panels, etc) can be connected to the RS485 bus at one time.

NOTE:

14. There MUST be only ONE (1) master in the RS485 communication bus. All others must be slaves (PASSIVE).
