DGC6 – UserManual
4.8.4.2 Service Interval
The description of the service concept is shown in 4.5.
The service interval of the controller is set here. If 0 is set, this function is disabled.
Symbol Description Default Function
XXXX Service Interval Entry of the interval between two services in days
4.8.4.3 Average Function
The Gas Controller calculates the arithmetic average value for each active measuring point out of 30 measurements
got within the time unit defined in the menu “AV Time“. This average is available in addition to the current value for
alarm evaluation. The selection which value should be used for evaluation is defined separately for each alarm in the
menu “Stage/Setpoint X”. In the average mode, the average value is indicated in the menu “Sensor Readings” next to
the current value.
The alarm evaluation of the control mode “Average Value” is overlaid by the current value, when the current value
exceeds the stage/setpoint defined in the menu “AV-Overlay”. The overlay is delayed by the time factor defined in this
menu. The average overlay function is only available for the gas type CO.
Symbol Description Default Function
120 s
120 ppm
AV Overlay
120 s
120 ppm
sec. = Delay time of average value overlay
ppm = Threshold for average overlay
900 s AV Time 900 s sec. = Time for calculation of the average value
Changes in the average time need a complete time cycle for new calculation!
4.8.4.4 Power On Time
Gas sensors need a warmup period, until the chemical process of the sensor reaches stable conditions. During this
warmup period the current signal can lead to an false alarm. Therefore, the Power On time is started at the Gas
Controller after you have turned on the power supply. During this timeout, the Gas Controller doesn’t activate alarms or
UPS relays. The Power On status displays on the first line of the home menu.
Attention: During the Power On phase the controller is in “Special Mode” and doesn’t perform further functions beside
the starting diagnostic procedures. A count-down Power On time in seconds is shown on the display.
Symbol Description Default Function
30 s Power On time 30 s XXX = Definition of the power On time (sec.)
4.8.4.5 Collective Fault Message Error Time
Future option for use as non-secure devices with allowed error delay.
4.8.4.6 Fault Activation by External DI
The collective fault output can be triggered by an external digital input in addition by using the ORing operation.
Example given, the fault message of the ventilation system could be connected.
Symbol Description Default Function
DI 0
BI 0
Digital Input 0
DI : 1-32 DI address via EP
BI : 1-96 DI address via MSB
4.8.4.7 GC Address
As yet no function is assigned, no display of GC address the current menu!
