Selection parameter

[0] Check air pressure monitor always

The air pressure monitor is checked before start-up of the combustion air fan.

Within a delay time of 180 seconds, it has to send a signal indicating that there is no combustion air pressure. If this is not the case, a safety shut-off is triggered after the delay time has expired following starting of the purge sequence, with the message (102) "FSC: CAP > MIN before CAF Start".

[1] Check air pressure monitor before fan start

The air pressure monitor check is only performed if the combustion air fan wasn't running (required if a switch-off delay has been set for the combustion air fan).

Within a delay time of 180 seconds, it has to send a signal indicating that there is no combustion air pressure. If this is not the case, a safety shut-off is triggered after the delay time has expired following starting of the purge sequence, with the message (102) "FSC: CAP > MIN before CAF Start".

The operation message of the combustion air fan must be monitored in the safety interlock circuit after fan start-up. If the safety interlock circuit is not included in the FSC input configuration after fan start-up, then monitoring must take place in the following safety interlock circuits:

• Safety interlock circuit fuel 1

• Safety interlock circuit fuel 2

• Safety interlock circuit for atomization

[2] Check air pressure monitor never

The air pressure monitor isn't checked.

You are only allowed to activate this parameter if the applicable standards and regulations permit this.
