DGC6 – UserManual
2.3 Special Status Mode
In the special status mode there are delayed measurements for service and modification, 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 flash 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 first 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.
