4.1.5.13 Oil pressure switch-max (X5- 02 pin 2)
The input is used for connecting an oil pressure switch-max. It is active only when firing
on oil.
The maximum oil pressure must not be exceeded. If exceeded, at least 1 safety
shutdown is initiated.
The input can be deactivated.
Parameter
OilPressureMax (activated / 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.
Parameter
PressReacTme (0.2s..MaxSafetyTGas)
4.1.5.14 Start release - oil (X6-01 pin 1)
The input is used for connecting a start signal, e.g. from the release contact of an
external outside air damper. It is only active when firing on oil.
The signal is anticipated in phase 21. If the signal is not delivered, or lost, shutdown is
initiated.
The input can be deactivated.
With the HT/FW-RedKo setting, the input can also be used for a second switching
contact (redundancy contact) for external flame supervision or external high
temperature supervision.
The redundancy contact must always be inverse to the first switching contact (at input
X6-01 pin 3, heavy oil direct start):
