A53 Z0 9 0020 L En Technical documentation
Analogue sensors:
The analogue oil pressure and water temperature sensors are used before start-up for the preheat and pre-
lube checks: the water temperature [E0030]and oil pressure [E0029] must be ABOVE their respective
thresholds (E1155 & E1154) for the engine to be allowed to start.
The default setting for these thresholds is zero. When the thresholds are set at zero, the readings from the
analogue sensors are not checked before start-up.
See the chapter concerning Preheat/ Pre-lube/ Plug preheat.
The water temperature [E0030] and oil pressure [E0029] variables can be used in equations.
Failure to start:
In case of insufficient oil pressure or water temperature post start-up, or in case of excess oil pressure or
water temperature (digital inputs) during start-up, an "Engine not OK" warning will appear.
Please check your oil pressure and water temperature sensors and their parameters.
WARNING:
The module doesn’t take into account an oil pressure fault during the start sequence.
