1. Introduction 1.1 Description

The Detcon X40 controller is a multi-channel gas detection control system designed to serve as a host monitor and controller for a network of gas detection sensors as well as a wide range of other field devices. All X40 models are configurable for up to 32 channels and can be customized using Detcon’s selection of I/O modules. The enclosure type will dictate the number of I/O modules that can be accommodated. These modules communicate with the controller via Modbus™ and are available in four channel sets for 4-20mA inputs, dry contact inputs, 4-20mA outputs and relay outputs. The modules are DIN rail mounted and stackable allowing for seamless system expansion. Remote mounted gas detection sensors can include any analog 4-20mA or RS-485 (Modbus™) serial output device such as toxic gas, combustible gas or oxygen deficiency sensors. Other remote field devices can include contact closure inputs such as liquid level, temperature, pressure or smoke detection devices. The analog sensors and field devices are interfaced to the I/O modules which communicate with the controller’s COMM1 Modbus™ master port. The serial sensors interface directly with the controller’s COMM1 port and do not require I/O modules. Thus, the types of sensors or field devices being interfaced will dictate the I/O modules needed for the X40 controller. Also, all configuration inputs are completely field-configurable which provides a distinctive combination of user configuration flexibility and expansion customization. The X40 controller utilizes a non-intrusive magnetic interface and displays the real time status of every sensor on a backlit LCD. Typical sensor status includes channel number, gas concentration, device tag (gas type) and alarm/fault status. Each channel provides three alarm levels (Alarm 1, Alarm 2 and Alarm 3) and fault for which the present status can be shown via the front panel LED indicators. Additional features include Alarm Inhibit, Alarm Reset and Alarm Silence (Acknowledge) functions. The X40 controller is available in different enclosure types to accommodate various customer needs. The NEMA 4 enclosures can also incorporate integral alarms such as a Strobe, or a horn or both. These enclosure types are NEMA 1 (N1P), NEMA 4X (N4X) and NEMA 7 (N7). The N1P is an indoor use, panel-mount enclosure. The N4X is an indoor/outdoor use, water/corrosion proof enclosure. The N7 is an indoor/outdoor use, explosion proof enclosure. These enclosure types are discussed in more detail in their perspective installation sections.

Model X40


1.2 System Operation

The heart of the X40 controller is the non-intrusive magnetic interface with backlit LCD display. The controller communicates with serial (RS-485) sensors and I/O modules using RS-485 Modbus™ RTU protocol. The X40 includes a primary Modbus™ interface (COMM1 Master) and a secondary Modbus™ interface (COMM2 Slave) that is used for communication with another controller or remote display. The Modbus™ master interface is used to communicate directly with Modbus™ capable sensors and Detcon’s I/O modules. The I/O modules are individually addressable and operate on 11.5-30VDC. The number of I/O modules supported by the X40 controller will vary depending on the enclosure type chosen due to physical space limitations. A maximum of 2 I/O modules will fit outside the X40-32-N1P enclosure, a maximum of 6 I/O modules will fit inside the X40-08-N4X enclosure and a maximum of 12 I/O modules will fit inside the X40-32-N4X enclosure. I/O modules are normally factory installed unless specifically instructed otherwise. The X40-32-N7 enclosure does not accommodate module installations. Modules for the N7 enclosure or any additional modules for the other enclosure types will have to be mounted in a separate enclosure by the customer. I/O modules are purchased separately. The available Detcon I/O modules include: Model DA-4 – Four Channel 4-20mA Input Module Model DI-4 – Four Channel Dry Contact Input Module Model AO-4 – Four Channel 4-20mA Output Module Model RL-4 – Four Alarm Relay Output Module Alarm values and fault condition can be field-configurable via the magnetic user interface to cause an assigned relay output or bank of relay outputs to fire, thus triggering external alarm devices. As gas alarm or fault conditions clear, the assigned relay outputs return to their normal states. Relays can be set-up as Energized/De-Energized, Latching/Non-Latching and Silenceable/Non-Silenceable. The X40 also allows for wiring of an external manual switch to act as an Acknowledge/Reset switch. The X40 controller can be configured for various I/O combinations at the Detcon factory based on application specific information provided by the customer on the Configuration Form. It must be verified that the correct quantity and type of I/O modules have been purchased to support the customer’s configuration requirements. On the Configuration Form, the customer should supply all site-specific information:

1) Number of gas channels 2) Detcon sensor model number and I/O type (Modbus™ or 4-20mA) for each channel 3) Range, units, and gas type for each channel 4) Alarm level(s) for each gas channel 5) Device Tag for each channel 6) Assignment and set-up information for each relay contact 7) Analog output requirements for each channel

NOTE: The set-up configuration is fully field-configurable and can be executed by the user in the field. Refer to section 7 System Operation and Configuration. Modifications to the set-up configuration are expected to take place at the customer’s site due to requirement changes and/or system expansions.

NOTE: The AC/DC converter board should be used to power the X40 controller only. Power to any I/O modules or sensors will have to be provided separately by the customer. The AC input voltage range must be between 90-264VAC.

4.2.2 DC Power and I/O Connections The X40-32-N7 controller can also be powered directly through a DC voltage source provided by the customer. The controller requires 11.5-30VDC to the PWR and GND terminals of connector J7. The wiring for a DC power input is shown in Figure 15.

NOTE: The supply of DC power should be from an isolated source with over-current protection as applicable. The input voltage range must be between 11.5-30VDC.

5. I/O Connections The quantity of I/O modules supported by the X40 controller will vary depending on the enclosure type chosen due to physical space limitations. A maximum of 2 I/O modules may be installed on the Model X40-32-N1P enclosure, a maximum of 6 I/O modules may be installed in the Model X40-08-N4X enclosure and a maximum of 12 I/O modules may be installed in the Model X40-32-N4X enclosure. Modules can be installed on the enclosure’s DIN rail.

NOTE: The X40-32-N7 enclosure does not accommodate module installations. Modules for the N7 enclosure or any additional modules for the other enclosure types will have to be mounted in a separate enclosure by the customer. Refer to Section 4.2.

NOTE: The X40-08-N4X enclosure with Alarm Strobe comes with at least one RL-4 module installed. This module is used to power the Alarm Strobe, and should not be removed.

I/O modules are mounted on an industry-standard 37.5 x 7.5 mm DIN rail (See Figure 16). Install the first I/O module at the end of the DIN rail nearest the male connector. Plug the male connector into the side of the module. Slide it all the way to the end stop. Add additional modules next to the first module. When installing additional I/O modules, make sure there is about 0.5 inch clearance on either side of the module and snap the module onto the DIN rail (the 0.5” spacing is to allow for connector clearance). Once the I/O module is snapped onto the DIN rail, slide it towards the adjacent module and assure that it firmly plugs into it. Connect the RS-485 and power female connector to the last module installed on the DIN rail. Secure the modules with an end stop.

Figure 16 I/O Module Installation

NOTE: The male connector must be plugged into the I/O module at one end of the DIN rail and the female connector must be plugged into the I/O module at the other end of the stack of I/O modules. If these connectors are not properly installed, communication with other RS-485 devices will not be possible.

NOTE: If no I/O modules are installed in the controller, the male connector must be plugged into the female connector for the RS-485 to communicate.

For addressable I/O modules or Modbus™ sensors that are being located remotely from the controller, Belden P/N 1502P cable is recommended for serial and power connections. For serial only connections, Belden P/N 9841 cable is recommended.

The 4-20mA signals from the sensors are communicated by the DA-4 modules to the controller using RS-485 Modbus™ RTU protocol therefore each DA-4 module must have a unique Modbus™ address. Modules are serially addressed in hex using the two rotary switches on the module’s front panel labeled MSD (most significant digit) and LSD (least significant digit). All DA-4 modules must be setup on the COMM1 (master) port of the controller. The DA-4 modules must be addressed within the range 01h-7Fh.

Model X40


A DA-4 module connected properly to the controller will have a flashing DATA COMM LED when polled to indicate a valid communication status and will provide the controller with a continuous reading of the sensor attached.

NOTE: DA-4 modules must be connected to the COMM1 port, they must be addressed correctly and only those channels associated with that DA-4 will be available.

After identifying the correct address for the DA-4 module, the channels to be used need to be defined and configured via the operator interface in section 7

5.4.1 Energized or De-Energized All alarms relays - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate in either energized or de-energized mode. In de-energized mode, the normally open contact is open if the alarm level has not been reached (alarm relays) or the sensor is not in fault (fault relay). In energized mode, the normally open contact is closed if the alarm level has not been reached (alarm relays) or the sensor is not in fault (fault relay). Energized mode provides for fail-safe operation since a loss of power or cable failure will cause the contact to be open.

5.4.2 Silenceable or Non-Silenceable All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate as silenceable, or non-silenceable. If an alarm or fault is configured as non-silenceable, the corresponding alarm LED and relay, once activated, will stay activated until the cause of the alarm or fault has cleared. If an alarm or fault is configured as silenceable, the corresponding alarm LED and relay, once activated, can be deactivated by acknowledging the Alarm Silence function on the front panel of the X40 controller or by activating the external acknowledge switch if one has been installed (See section 7.1.4 ENTER and RESET/ACK Switch and section 9.1 Optional Remote Alarm Reset/Acknowledge Switch).

5.4.3 Latching or Non-Latching Relays All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured as either latching or non-latching. In non-latching mode, the relay is deactivated as soon as the sensor alarm (alarm relays) or fault (fault relay) condition is cleared. In latching mode, the relay remains active even after the alarm or fault condition has cleared. Once activated, the relay can only be deactivated by acknowledging the Alarm Reset function on the front panel of the X40 controller or by activating the external reset switch if one has been installed (See section 7.1.4 ENTER and RESET/ACK Switch and section 9.1 Optional Remote Alarm Reset/Acknowledge Switch). 5.5 Serial Output Gas Sensors (RS-485)

Serial output gas sensors can be interfaced with the X40 controller without the need for I/O modules. This is accomplished by connecting the sensors in series to the controller’s primary RS-485 Modbus™ interface (COMM1). Connect the five wires of a Modbus™ capable sensor (Detcon Model 100, Model 600 and Model 700 series, typically) to the Modbus™ DIN rail mounted terminal block, labeled “RS-485 MASTER” and “VDC Out” (See Figure 22). For the X40-32-N7 controller, the serial sensors can be connected directly to the J7 connector of the controller’s PCA (See section 4.2).

System Operation and Configuration (Seconnected and configured to the controller will respoto the alarm set points of the associated channel. If the controller does not detect an RL-4 module, the blue LED (Fault) will start flashing. Go to the FLASHING BLUE LED CODES menu to identify the problem (See section 7.3.11). Each relay within the bank can be set as Energized/De-Energized, Silenceable/Non-Silenceable, and

Follow generally accepted guidelines for RS-485 serial networks. Do not wire I/O modules and/or Modbus™ gas sensors in long-distance ‘T-Tap’ configurations. Instead, use a “daisy-chain” wiring scheme.

Use Detcon recommended cabling whenever possible. • Belden P/N 1502P cable is recommended for a single cable providing serial communications

and power. • Belden P/N 9841 cable is recommended for a single cable providing serial communications

only. Ground the cable shielding at the X40 controller only. Other points of grounding may cause a ground

. System Operation and Configuration The setup of the controller is critical for proper operation. Modbus™ addresses must be correct on all the devices connected to the controller before the controller will acknowledge them. The number of sensors must be entered into the controller to allow it to communicate with them. Four basic areas need to be configured:

The number of sensors must be determined before setup begins. The sensor’s channel information must be configured to match the sensor connected. If 4-20mA outputs are required, they must be set up and configured. Relay modules and banks must be configured.

7.1 Operator Interface

The operator interface of the X40 controller is accomplished via four internal magnetic switches located above the controller’s backlit LCD display. The four switches offer a non-intrusive interface and allow for complete configuration of the controller. These switches are labeled: PROG, “ ” (Up Arrow), “ ” (Down Arrow) and ENTER. The ENTER switch also doubles as a RESET/ACK switch from the Main Display only (Not in Menu Mode). With reference to the Menu Flow Chart (See Figure 25), it is easy to learn how to navigate the menus and make changes.

The magnetic programming tool (See Figure 23) is used to operate the magnetic switches. Switch action is defined as a momentary contact (hold) on a switch marker (⊗). For momentary contact, the programming magnet is briefly held on the switch marker (⊗) and then removed. This action will be referred to as a “swipe” for the remainder of this manual.

8. Modbus™ Communications The X40 controller features a Modbus™ compatible communications protocol and is addressable by a PLC, PC/HMI, DCS or other Modbus™ RTU master-polling devices. Communication is accomplished by two wire half duplex RS-485, 9600 baud, 8 data bits, 1 stop bit, no parity, through the controllers primary port (COMM1). A Modbus™ RTU master device up to 4000 feet away can theoretically poll up to 64 different X40 controllers. This number may not be realistic in harsh environments where noise and/or wiring conditions would make it impractical to place so many devices on the same pair of wires. If multiple controllers are being used on a single Modbus™ network, each controller must be set to a different device address. 8.1 Modbus™ Register Map

. Options 9.1 Optional Remote Alarm Reset/Acknowledge Switch

Model X40 controllers are designed for an optional Remote Alarm Reset/Acknowledge Switch. This enables the user to reset or acknowledge alarms without having to open the X40 enclosure. The Reset Switch is a momentary normally open push button type switch and will typically be mounted on the bottom or side of the NEMA 4X enclosure. For the other enclosure types, the switch will have to be mounted externally such as in the bottom of a J-Box if one is available. Connect the switch to the terminals of the terminal block labeled “REMOTE RESET” for the N1P and N4X controllers (See Figure 26) For the N7 controller, connect the switch to the terminals “SW” on connector J7 (See Figure 27) Once installed, pushing the switch will execute the reset/acknowledge function.

he Model X40 controller offers a wireless option that is designed to take Modbus™ communication between the controller and other devices to a wireless platform. This option takes local Modbus™ communication, and using a wireless network of transceivers, broadcasts this information throughout a wireless network platform, creating a seamless network of Modbus™ devices that need not be physically connected in any way. The wireless function of the X40 Controller is made possible by Detcon’s RXT-320 wireless transceiver. This transceiver transmits signal data such as analog 4-20mA DC or serial Modbus™ and can support up to 32 devices. It operates at 2.4GHz and conforms to non-licensed radio frequency appliance usage around the world. Wireless network integrity and security is accomplished using direct sequence spread spectrum wireless mesh technology. Wireless applications can be as simple as a single field device communicating with a host controller or any number of field devices forming a network of subscribers. Each device in the network is assigned a Network ID and a Modbus™ address. Processing power is based in a designated Modbus™ master while every slave device in the network is capable of functioning as a router and repeater for all other devices in the network. This means that subscribers can “hop” through neighboring devices to communicate with each other thereby widening network access points. This unique and innovative technology is designed to create a r tes around congestion and line-of-

Figure 28 RXT-320 Wireless Assembly for X40 Controller

NOTE: It is highly recommended to install the cable inside rigid metal conduit to eliminate potential EMI and RFI interference and to maintain a Class I Division I rating.

NOTE: A 6-32 or 8-32 threaded exterior ground point is provided on most junction boxes for an external ground. If the transceiver assembly is not mechanically grounded, an external ground strap must be used to ensure that the transceiver is electrically grounded.

Detcon offers an optional mounting plate that can be used for mounting the RXT-320 wireless assembly to the pole. If ordered with this option, secure the wireless transceiver assembly to the mounting plate using two of the four 3/8” diameter holes located on the top face of the mounting plate (If not already done so from the factory). The mounting plate can then be mounted to a pole with two U-Bolts secured through the 7/16” holes of the mounting plate’s base (See Figure 29).

NOTE: Any unused ports should be blocked with suitable ¾” male NPT plugs. Detcon supplies one ¾” NPT male plug with each J-box enclosure. If connections are other than ¾” NPT, use an appropriate male plug of like construction material.

NOTE: Use suitable cord connectors (cable glands) for cable entering the X40 controller or the transceiver’s J-Box.

NOTE: The Detcon Warranty does not cover water damage resulting from water leaking into the enclosure.

9.2.2 RXT-320 Wiring If the RXT-320 transceiver does not come pre-wired from the Detcon factory, it will require four conductor connections for the power supply and Modbus™ interface. DC power is provided to the transceiver by the controller’s 24VDC power supply or a Detcon SmartWireless battery pack. The RS-485 interface is accomplished by connecting the transceiver assembly to the controller’s master and/or slave RS-485 Modbus™ interface. Connect four wires of a power & Modbus™ capable cable (Belden P/N 1502P is recommended) to the Modbus™ TB2 DIN rail mounted terminal block. Connect the other end of the cable to the J2 connector of the Terminal Board located inside the J-Box of the transceiver (See Figure 30, Figure 31, Figure 33, and Figure 34).
