Model X40
Model X40 Instruction Manual Rev. 3.4 Page 1 of 65
1.0 Introduction
1.1 Features
The Detcon X40 controller (Figure 1) is a multi-channel gas detection control system. The X40 serves as a
host monitor/controller for a network of gas detection sensors and various other field devices. The
controller offers a non-intrusive magnetic interface with backlit LCD display and Modbus™technology
that supports either wireless or a hard wire sensor connection. The X40 is equipped with an auto configure
feature to automatically search the Modbus™addresses for various Detcon equipment associated with the
controller and adds the equipment to the controller without user intervention.
Remote mounted gas detection sensors include any analog 4-20mA or RS-485 (Modbus™) serial devices
such as;
toxic gas,
combustible gas, or
oxygen deficiency sensors.
Remote field devices include contact closure inputs such as:
liquid level,
temperature,
pressure, or
smoke detection devices.

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 2 of 65
1.2 LCD Main Display Function
The main display is an 11/4"x6" backlit LCD that is four lines by forty characters and displays up to eight
configured channels at one time. The four internal magnetic switches are located above the backlit LCD
display and offer basic navigation for a complete configuration of the controller (Section 5.1).
Real time sensor status includes:
channel number
gas concentration,
device tag (gas type)
alarm/fault status.
Each channel displays the current status of three alarm levels and a fault condition on the front panel LED
indicators.
1.3 Modbus™Communication
The controller uses the RS-485 Modbus™RTU protocol to communicate with RS-485 serial sensors and
I/O modules. A secondary Modbus™port is addressable by a PLC, PC/HMI, DCS or other Modbus™
RTU master-polling devices.
Primary Modbus™Interface (COMM1 Master)
Uses two-wire half duplex RS-485, 9600 baud, 8 data bits, 1 stop bit, no parity. Communicates directly
with Modbus™ capable sensors and Detconꞌs independently addressable I/O modules that operate on 11.5-
30VDC.
Secondary Modbus™Interface (COMM2 Slave)
The Modbus™slave interface communicates with the remote display or an additional controller.
1.4 Secure Digital Card (SD Card)
The X40 controller allows data logging when an SD memory card is installed. The card must be installed
on the back of the PCA (printed circuit assembly) before the controller is powered up. The controller will
automatically format the card (Section 4.0) and create the necessary files for data logging.
NOTE Data logging does not occur during the first 10 minutes after power-up of the unit. This
delay allows the sensors time to stabilize, so that inaccurate or faulty readings will not be
logged during this stabilization period.
1.5 I/O Modules and Connections
A maximum of 32 sensor channels are configurable for the X40 models and are customizable using
Detconꞌs I/O modules. Accommodation for the I/O modules relies on the type of enclosure utilized.
Seamless system expansion is accomplished through DIN rail mounted and stackable modules. The
modules communicate with the controller using Modbus™technology and are available in four types;
4-20mA inputs
dry contact inputs
4-20mA outputs
relay outputs.

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 3 of 65
The analog sensors and analog field devices interfaced to the I/O modules communicate with the COMM1
Modbus™master port on the X40 controller via the I/O Module. Serial sensors interface directly with the
COMM1 port and do not require I/O modules. The types of sensors/field devices interfaced will dictate the
I/O modules required for the X40 controller. Configuration inputs are completely field-configurable
providing a distinctive combination of flexibility and expansion for the customer.
I/O modules are factory installed unless specifically instructed otherwise. The number of I/O modules that
can be installed in the X40 enclosure is dictated by the enclosure due to physical space limitations.
Additional I/O modules in excess of the maximum allowed for each enclosure must be mounted in a
separate enclosure by the customer. The module limits for each enclosure varies dependent on the type of
enclosure, and the set-up of the particular unit. The typical limitations are as follows:
• X40-32-N1P enclosure - maximum of two I/O modules (Mounted on the back, outside)
• X40-08-N4X enclosure - maximum of six I/O modules inside
• X40-32-N4X enclosure - maximum of twelve I/O modules inside
• X40-32-N7 enclosure - does not accommodate module installations
The X40 controller can be configured for various I/O module combinations at the Detcon factory.
Customer application/site specific information must be provided on the Configuration Form. Information
provided is verified for correct quantity and type of I/O modules to support application/site requirements.
The customer should supply the following site specific information:
1. Number of gas/sensor 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 executed by the user in the field (Section 5.0). Modifications to
are expected to take place on site due to requirement changes and/or system expansions.

must have a unique Modbus™address set between A0 and AFh.

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 4 of 65
Alarm Relay Outputs (RL-4)
• Alarms can be used to control (fire) annunciating devices or signal inputs to other control
devices.
• Four Form C, Single Pole Double Throw (SPDT), 5 Amp relay contacts each assigned specifically
to one alarm.
• Uses RS-485 Modbus™RTU protocol to communicate the outputs and must have a unique
Modbus™address set between 80 and 8Fh.
• The X40 controller is configured with a maximum of eight separate relay banks each holding
up to two RL-4 modules.
• Anytime a specific alarm (e.g. Alarm 3) is fired for a particular module in a bank (e.g. Bank2),
all corresponding alarms (e.g. Alarm 3’s) for all modules in that particular bank (e.g. Bank2)
are also triggered.
RS-485 Serial Gas Sensors (Modbus™)
RS-485 Serial gas sensors can be interfaced directly with the X40 controller without the use of I/O modules
by connecting the sensors in a series to the primary RS-485 Modbus™interface (RS-485 Master Port).
1.6 Enclosure Types
The X40 controller is available in three enclosure types to accommodate various customer needs and
configurations. The number of I/O modules varies depending on the enclosure type and configuration.
N1P Enclosure
The Model X40-32-N1P controller is housed in a NEMA 1 panel mount enclosure for indoor use. The
internal power supply of the N1P controller converts 100-120/220-240VAC to 24VDC and can power a
maximum of 32 sensors and associated I/O modules. A maximum of two I/O modules can be installed on
the outside of the controller. Additional modules must be mounted separately by the customer.
The power supply for the N1P is capable of handling AC inputs from 100-120/220-240VAC, 50-60Hz
without degradation. The X40 controller can be powered by an external DC source that meets the input
requirements (11.5-30VDC) of the unit if AC power is not preferred or available. DC power can be used
for primary or back-up power in the event of an AC power failure. RS-485 and power out are provided for
connection to sensors attached to the unit.
N4X Enclosure
The X40 controller is available in two different size models for the N4X enclosure type. Both the X40-08-
N4X and X40-32-N4X controllers are housed in a NEMA 4X water/corrosion proof enclosure for
indoor/outdoor use. The power supplies for both enclosure types are capable of handling AC inputs from
100-120/220-240VAC, 50-60Hz without degradation. The X40-N4X can be powered by an external DC
source that meets the input requirements (11.5-30VDC) of the X40 if AC power is not preferred or
available. This input can be used for primary power or back-up power in the event of an AC power failure.
The DC output voltage is capable of delivering a maximum of 2 Amps of current to the sensors attached to
the X40 controller.
RS-485 master port and power out are provided for connection to serial sensors attached to the unit.
The X40-08-N4X enclosure houses a maximum of six I/O modules inside of the controller and is capable
of communicating with a maximum of 32 devices. The enclosure can incorporate integral alarms such as
an 8" strobe mounted on the top of the enclosure, horn, or both.
The X40-32-N4X enclosure houses a maximum of twelve I/O modules inside of the controller and
communicates with up to 32 devices.

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 5 of 65
N7 Enclosure
The X40-32-N7 controller is housed in an explosion proof NEMA 7 enclosure for indoor/outdoor use. The
N7 enclosure does not accommodate module installations. Modules must be mounted externally by the
customer. Any sensors and associated I/O modules will need to be powered separately by the customer.
The X40 controller can be powered directly by an external DC source provided by the customer, which
meets the input requirements (11.5-30VDC) of the unit. A plug-in male connector is provided for input
wiring terminations. A plug-in male connector provides quick disconnect convenience during replacement
or servicing.
An optional AC/DC converter board inside a condulet/J-Box is available from Detcon to only power the N7
controller with an AC voltage source. The converter uses AC inputs between 100-240VAC and provides a
24VDC (up to 167mA) output. Power to I/O modules or sensors must be provided by the customer.
Detcon offers an optional mounting plate for mounting the X40-32-N7 controller to a pole.
1.7 Alarms and Fault Condition
The alarms (Alarm 1, Alarm 2, Alarm 3, and Fault) can be used to control annunciating devices or as signal
inputs to other control devices. The field configurable magnetic user interface permits alarm values and
fault condition to cause an assigned relay or bank of relay outputs to fire, triggering external alarm devices.
The assigned relay outputs will return to normal state when a gas alarm or a fault condition clears.
Additionally, an external manual switch can be wired to the X40, acting as an acknowledge/reset switch
(Section 1.12).
When the X40 is in alarm, the display will remain on the channel group with the alarm. When there is
more than one alarm/fault, the controller will cycle through group pages with alarms/faults including the
transceiver, RL-4/alarm station, and AO-4 group pages. The user can manually cycle to any group page
that exists using the arrow switches. After a time out period, the X40 will resume page cycle protocols
based upon the existence of alarms/faults. Four LED indicators on the front panel show alarm/fault alarm
output status and are labeled respectively as ALM 1 (yellow), ALM 2 (yellow), ALM 3 (red), and FAULT
(blue).
All alarms can be configured Energized/De-Energized, Latching/Non-Latching and Silenceable/Non-
Silenceable for the relays.
Energized Mode
The normally open contact is closed if the alarm level has not been reached or if the sensor is not in fault.
Energized mode provides for fail-safe operation since a loss of power or cable failure will cause the contact
to be open.
De-Energized Mode
The normally open contact is open if the alarm level has not been reached or if the sensor is not in fault.
Silenceable
The corresponding alarm LED and relay 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 installed
(Section 7.0).

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 6 of 65
Non-Silenceable
The corresponding alarm LED and relay will remain activated until the cause of the alarm or fault is clear.
Latching Mode
The relay can be deactivated after the alarm condition has cleared by acknowledging the Alarm Reset
function on the front panel of the X40 controller or by activating the external reset switch if installed
(Section 7.0).
Non-Latching Mode
The relay is deactivated as soon as the sensor alarm or fault condition is clear.
1.8 System Operation
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 the devices. Each wireless
sensor must have a unique Modbus address (refer to sensor manual for details). The number of sensors is
determined during auto configure if the addresses on the sensors and modules are set correctly.
The operator interface of the X40 utilizes four internal magnetic switches located above the controller’s
backlit LCD display. The four switches provide a non-intrusive interface and allow for complete
configuration of the controller and are labeled as follows:
•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).

and Acknowledge functions.
The Reset function releases all latched relays once the alarm/fault condition has cleared.
The Acknowledge function will disengage any silenceable relays that are in an active state.
This is used to silence alarms once the end-user has assessed the alarm condition.
The RESET/ACKNOWLEDGE function of the switch is only applicable from the Main Display
and not while in Main Menu mode.
1.10 Main Display Functions
When the X40 is in alarm, the LCD display will stay on the channel group with the channel in alarm. If
more than one alarm/fault exists, the X40 will cycle through group pages with alarms/faults including the
transceiver, RL-4/alarm station, and AO-4 group pages. At any time the user can manually cycle to any
group page using the arrow switches. After a time out period (15 seconds), the X40 will resume page cycle
protocols based upon the existence of alarms/faults. Four LED indicators on the front panel show alarm and
fault alarm output status. The LEDs represent ALM 1 (yellow), ALM 2 (yellow), ALM 3 (red) and FAULT
(blue).
NOTE The X40 only cycles through sensor group pages when no alarms/faults exist.

1.11 Menu Function
The X40 controller setup is accomplished through the Main Menu and consists of seven menu items:
1. Auto Configure System
2. Setup Channel Data
3. Set Channel Alarms
4. Set Relay Function
5. Inhibit & Alarm Test Mode
6. System Diagnostics
7. Time and Date
8. View TWA & Peak
Auto Configure System
The Auto Configure System automatically configures the X40 controller when other Detcon devices are
installed as part of the control system. When activated, the controller searches for Detcon serial sensors,
RL-4 modules/alarm stations, AO-4 modules and wireless radio modules.
Setup Channel Data
Setup Channel Data displays the Modbus ID, device type, range, and gas type for each channel. The
assigned RL4 bank and number of analog inputs (for channels using an RXT-320) is also displayed. Only
the gas type can be changed by the user. No other values on this screen can be changed.

Model X40
Model X40 Instruction Manual Rev. 3.4 Page 11 of 65
Set Channel Alarms
All sensors have three alarm settings ALM1 (Alarm 1), ALM2 (Alarm 2) and ALM3 (Alarm 3). The user
establishes the alarm levels for each sensor depending on the range. The values represent the alarm level
set points and entered in 5% increments of the full-scale range selected for that channel. In ascending
mode the relay is activated when the concentration is above the alarm threshold. In descending mode, the
alarm relay is activated when the concentration is below the alarm threshold. Alarms are usually
ascending, with the exception of oxygen sensors. The alarm ascending level can be either Y (Yes) or N
(No).
Set Relay (Alarm) Functions
The Set Relay Functions menu enables configuration (Latching, Energized and Silenceable) of the relays in
Bank1-8. Each relay bank has three relay outputs for ALM1, ALM2 and ALM3 and a fourth relay output
for the Fault condition. All relays in the bank must be configured for the following three settings:
Latching or Non-Latching
Energized or De-Energized,
Silenceable or Non-Silenceable
Inhibit and Alarm Test Mode
The Inhibit and Alarm Test Mode permits the user to inhibit functionality of alarms in the network,
simulate alarm conditions and verify relay contacts. The Inhibit mode disables alarm outputs while sensor
are being calibrated or tested. The Alarm Test Mode simulates alarm conditions by increasing the gas
readings from zero for all active gas channels at increments of 5% full scale then decrease back to zero and
exit the test mode.
System Diagnostics
The System Diagnostics menu performs complete functionality tests for:
LCD display
Panel LEDꞌs
External reset switch
Relays
Modbus™interface
Time and Date
The Time and Date menu enables the user to effortlessly establish the time and date. The time will be
displayed as military time (24hrs) in hours, minutes and seconds. The date will be displayed as the month,
day and two digit year. If the time and/or date are not correct, they can be updated.
View TWA and Peak
The View TWA and Peak menu permits viewing the recorded time weighted average (TWA) and peak
readings for each channel represented by its assigned gas sensor. The data is recorded on the SD card with
the date, time, channel number, TWA and peak readings each time the controller polls a sensor. Data on
the SD card is viewed by using the Detcon Log File Viewer application on a computer.
1.12 Optional Remote Alarm Reset/Acknowledge Switch
An optional remote Alarm Reset/Acknowledge switch enables the user to reset or acknowledge alarms
without having to open the X40 enclosure. The switch is a normally open push button mounted on the
bottom or side of the NEMA 4X enclosure. For the N1P and N7 enclosures, the switch must be mounted
externally (e.g. bottom of the J-Box).

1.13 Wireless Option
The Model X40 controller offers a wireless option that uses Modbus™technology to connect the controller
and other devices to a wireless platform. The local Modbus™communication uses a wireless grid of
transceivers to broadcast information throughout the wireless network, creating a seamless network of
Modbus™devices that are not physically connected. The transceiver operates at 2.4GHz and conforms to
non-licensed radio frequency usage worldwide. Spread spectrum technology supports integrity and
security for the wireless network.
Wireless applications can be a single field device communicating with a host controller or multiple field
devices forming a network of subscribers. Each device in the network is assigned a Network ID and a
Modbus™address. If radio communication is impossible due to distance or obstruction, each slave device
is capable of locating an alternate route using an additional radio to communicate with the designated
device. This innovative technology is designed to create a robust network that automatically routes around
congestion and line-of-sight obstacles while improving throughput as subscriber device density increases.
Refer to the Wireless Radio Module instruction manual for detailed information.
Wireless Radio Module Mounting
Detcon’s wireless radio modules are factory installed. The radio module has a rotary dial for setting the RF
channel. The radio module, wireless sensors, and wireless alarm stations must all be set to the same RF
channel to operate correctly.
NOTE The radio module, wireless sensors, and wireless alarm stations must all be set to the same
RF channel to operate correctly.
Figure 5 Radio Module
For NEMA 1 or NEMA 12 units the antenna is typically mounted separately, using Detcon’s remote
antenna mounting kit. On NEMA 4 units the antenna can be installed on the top of the enclosure or
separated up to 50m using Detcon’s remote antenna mounting kit (Section 2.3). On N7 units the antenna is
mounted on the Transceiver, and is part of the unit (Section 2.4). Detcon’s antennas are vertically
polarized. This means that there is an RF ‘Dead-Zone’ directly above and below any transmitting antenna.
Because of this, any device with an antenna that is located near an elevated antenna should be placed at
least as far from the elevated antenna as the antenna is high. For example, if an antenna is 20ft. off the
ground, the nearest antenna should be at least 20 ft. away.
