4.8.10 Define the Failure Relay
In this menu you can define one of the relays as fault indication relay. See also fault management (4.1)

4.8.11 Acknowledge a Relay in Latching Mode by a DI
This configurable functionality is available from version 9.02.
All relays currently in latching mode can be acknowledged via the set DI.
See also 4.5.3 latching function.
Optional:
All resettable fault messages are acknowledged in addition by activating this digital input. See also 4.1 Fault
management function.
Attention:
This function is not suitable for safety-relevant applications for it may happen that errors not yet recognized by
the operator would be acknowledged at the same time.
This input should only be actuated by a key switch.

4.8.12 Power On Time
Gas sensors need a running-in period, until the chemical process of the sensor reaches stable conditions.
During this running-in period the current signal can lead to an unwanted releasing of a pseudo alarm. Therefore
the Power ON time is started at the Gas Controller after switching on of the power supply. While this time is
running out, the Gas Controller does not activate alarms. The power on status occurs on the first line of the
starting menu.

4.8.13 Registration of Expansion Modules
The CGD-05 system manages up to 23 expansion modules PE-05 with four analog inputs each. The PE-05
modules with the addresses 1 to 5 dispose of 5 alarm relays and 2 analog outputs each. Connected PE- 05
modules are registered in this menu with the desired function (only alarm relay or alarm relay + analog input). A
module address is assigned to every PE-05 module via the address switch.
The controller checks the communication to the registered PE-05 modules and shows a fault signal in case of a
communication error. To recognize the position of the PE-05 modules a module address is assigned to each
module by the address selector. See table.
PE Module 0:
This is the in/output board in the CG-05 Controller Module. The module is always active, but the function “Only
alarm relay or alarm relay + analog inputs” can be selected.
Active analog inputs at an PE module occupy the four MP addresses; therefore they aren’t available any longer
for the bus transmitters.
The table shows the assignment of the relay numbers and of the analog in/outputs to the PE module
addresses.
