4.1.5.11 Gas pressure switch-max (X9-03 pin 3)

The input is used for connecting the gas pressure switch-max. It is only active when
firing on gas.
The signal is anticipated when first safety time starts.
If the gas pressure is exceeded, safety shutdown is initiated in any case.
The input can be deactivated.
Parameter GasPressureMax (activated / deactivated)
There is a delayed reaction to loss of gas pressure during safety time to prevent
shutdown caused by pressure shocks when the valves open.
Parameter PressReacTme (0.2s..MaxSafetyTGas)

4.1.5.12 Oil pressure switch-min (X5-01 pin 2)

The input is used for connecting an oil pressure switch-min. It is only active when firing
on oil.
It is anticipated that the pressure signal appears during preignition to be critically valued
(with HOgp in phase 44). If there is no oil pressure, or if the oil pressure drops, safety
shutdown is initiated in any case. The signal is valued from safety time. If there is no oil
pressure, safety shutdown is initiated in any case.
Parameter OilPressureMin (activated)
OilPressureMin (act from ts)
Note!
During preignition, there is no waiting for the oil pressure. The signal is valued from the
first safety time.
The signal is valued from first safety time. If there is no oil pressure, safety shutdown
is initiated in any case.
Caution!
This kind of parameterization is only permitted in case of individual system
approvals.
The input can be deactivated
There is a delayed reaction to loss of oil pressure during safety time to prevent
shutdown caused by pressure shocks when the valves open.
