Corrective action
The time defined by Max SafteyTGas(Oil) is less than
the time defined by parameter SafteyTmeGas(Oil).
Parameter Max SafteyTGas(Oil) can only be changed
by Siemens. Lengthen SafteyTmeGas(Oil).
Check inputs according to the diagnostic code.
Disconnect wires or activate inputs for the specific
