DGC6 Analog Gas Controller
1 Application
The PolyGard®2 DGC6 Gas Controller is used for monitoring, detection and warning of toxic and combustible gases
and vapors in the ambient air. The DGC6 Gas Controller fullls the requirements according to the European Standard
EN 50545-1 for the stationary monitoring of carbon monoxide (CO), nitrogen dioxide (NO2) and combustible gases
in underground garages, tunnels, go-cart race courses etc. The DGC6 Gas Controller also meets the requirements
according to EN 378, VBG 20 and the guidelines “Safety requirements for ammonia (NH3) refrigeration systems”. The
Gas Controller can be used as well for monitoring other gases and measuring values.
The intended sites are all areas being directly connected to the public low voltage supply, e.g. residential, commercial
and industrial ranges as well as small enterprises (according to EN 5502). The Gas Controller may only be used in
ambient conditions as specied in the technical datasheet.
The PolyGard®2 Gas Controller DGC6 must not be used in potentially explosive atmospheres.
2 Description
The Gas Controller is a measuring, warning and control system for the continuous monitoring of dierent toxic or
combustible gases and vapors as well as of Freon refrigerants. The DGC6 is suitable for the connection of up to 96
digital sensors like the DT6 Series via the 4-wire bus. Up to 32 analog inputs for the connection of sensors with 4 to
20 mA signal interface are available in addition. The controller can be employed as pure analog controller, as analog/
digital or as digital controller. The total number of connected sensors, however, may not exceed 128 sensors.
Up to four programmable alarm thresholds are available for each sensor. Each sensor alarm threshold can be
assigned up to one of the 32 power relays or up to one of the 96 signal relays. Relays have potential-free change-over
contacts.
The Gas Controller menu structure is very intuitive and simple to use. A number of integrated parameters allow
customized programming for various gas measuring scenarios. Conguration is menu-driven via the keypad. For faster
and easy conguration, you can use the PC based conguration software DGC6-EasyConf.
Prior to commissioning please consult the guidelines for wiring and commissioning of the hardware.
2.1 Normal Mode
In normal mode, the gas concentrations of the active sensors are continuously polled and displayed at the (liquid
crystal) LC display. In addition, the controller continuously monitors itself, its outputs and the communication to all
active sensors and modules.
2.2 Alarm Mode
If the gas concentration reaches or exceeds the programmed alarm threshold, the alarm is triggered, the assigned
alarm relay is activated and the alarm LED (orange for alarm 1, red for alarm 2 + n) starts to ash. The set alarm can
be read from the menu Alarm Status. When the gas concentration falls below the alarm threshold and programmed
hysteresis, the alarm is automatically reset. In latching mode, the alarm must be reset manually at the triggering device
after falling below the threshold. This function is required for combustible gases detected by catalytic bead sensors
generating a falling signal at too high gas concentrations.

DGC6 – UserManual
2.3 Special Status Mode
In the special status mode there are delayed measurements for service and modication, but no alarm evaluation. The
special status is indicated on the display and it always activates the fault relay.
The controller adopts the special status when:
- faults of one or more active devices occur,
- the operation starts up after return of voltage (power on),
- the service mode is activated by the user,
- the user reads or changes parameters,
- an alarm or signal relay is manually overridden in the “Stage Status” menu or via digital inputs.
2.3.1 Fault Mode
If the controller detects an incorrect communication of an active sensor or module, or if an analog signal is outside
the admissible range (< 3.0 mA > 21.2 mA), or if there are internal function errors coming from the self-control
modules incl. watchdog and voltage control, the assigned fault relay is set and the error LED starts to ash Yellow.
The error is displayed in the menu Error Status in clear text. After removal of the cause, the error message has to be
acknowledged (reset) manually in the menu System Errors.
2.3.2 Restart Mode (Warm-up Operation)
Gas sensors need a running-in period, until the chemical process of the sensor reaches stable conditions. During this
running-in period the sensor signal can create a false alarm.
Depending on the connected sensor types, the longest warm-up time has to be entered as power-on time in the
controller. This “Power On Time” is started at the Gas Controller after switching on the power supply and/or after the
return of voltage. During this initial startup phase, the Gas Controller doesn’t display any values and doesn’t activate
any alarms; the controller system isn’t ready for use.
The power-on status occurs on the rst line of the home display.
2.3.3 Service Mode
This operation mode includes commissioning, calibration, testing, repair and decommissioning.
The service mode can be enabled for a single sensor, for a group of sensors as well as for the complete system. In
active service mode pending alarms for the concerned devices are held, but new alarms are suppressed.
2.3.4 UPS Functionality
The supply voltage is monitored in all modes. When reaching the battery voltage in the power pack, the UPS function
of the controller is enabled and the connected battery is charged.
If the power fails, the battery voltage drops down and generates the power failure message.
At empty battery voltage, the battery is separated from the circuit (function of deep discharge protection). When the
power is restored, there will be an automatic return to the charging mode.
No settings and therefore no parameters are required for the UPS functionality.

3.3 Code Levels
According to the regulations of all national and international standards for gas warning systems, all inputs and changes
are protected by a four-digit numeric code (= password) against unauthorized intervention. The menu windows for
status messages and measuring values are visible without entering a code.
The cancellation of a password level takes place when no buttons are pushed within 15 minutes.
The code levels are classied in order of priority: Priority 1 has top priority.
Priority 1: Upper Level (password 9001 – not changeable)
Code level priority 1 is intended for the service technician of the installer to change parameters and set-points. This
password allows working on all settings. For opening the parameter menus you must rst activate the service mode
after code entry.
Priority 2: Lower Level (password 1234 – not changeable)
Code level priority 2 allows the operator:
- to acknowledge faults
- to set date and time
- to congure and to operate the data logger option, after activation of the operation mode “Service Mode”
- to read all parameters
- to manually operate test

4.1 Fault Management
The integrated fault management records the rst 100 faults with date and time stamps in the menu “System Errors”.
Additionally a record of the faults occurs in the “History Error”, which can only be read and reset by the service
technician.
A pending fault activates the fault indication relay. The yellow LED (Fault) starts to ash; the fault is displayed in plain
text with date and time in the starting menu.
In case of the fault of a connected sensor the alarms dened in the menu “SP Parameter” are activated in addition.
4.1.1 Acknowledge a Fault
According to the directives for gas measuring, accumulated errors are allowed to be acknowledged automatically. The
automatic acknowledgment of a fault is only possible after having removed the cause!
4.1.2 History Error
The menu “History Error” in the main menu “System Errors” can only be opened via the code level priority 1.
In the error memory, the rst 100 faults that have occurred and have already been acknowledged in the menu “System
Error” are listed for the service technician in non volatile memory.
Attention:
This memory should always be read during maintenance, relevant faults should be tracked and entered in the service
logbook, and nally the memory should be emptied.

DGC6 – UserManual
4.1.3 System Messages and Errors
The devices connected via the analog interface can only report their malfunction by signal under range or over range.
The reason for signal under range usually occurs because of loss of signal do to missing signal from wiring problems.
The following system error messages of the analog interface are detected and recorded:
“AP 0X Overrange” Current signal at analog input > 21.2 mA
Cause: Short-circuit at analog input, analog sensor not calibrated, or defective.
Solution: Check cable to analog sensor, make calibration, replace sensor.
“AP Underrange” Current signal at analog input < 3.0 mA
Cause: Wire break at analog input, analog sensor not calibrated, or defective.
Solution: Check cable to analog sensor, make calibration, replace sensor.
Any device with microprocessor and digital communication - such as digital heads, sensor boards, EP modules and
even the controller - is equipped with extensive self-monitoring systems and diagnostic functions.
They enable detailed conclusions about the error causes and help the installers and operators to quickly determine the
cause, and/or to arrange an exchange.
These errors can only be transmitted when the connection to the central (or tool) is intact.
