8. Powering
The Surlok connector (+V BATT) is dedicated to the connection to the PLUS connector of the battery. It is
rated up to 120A continuous current. All current sourced from PDM to the loads flow here.
GND connections in this example are divided in GND for PDM logic and Low side function up to 34A, GND
for external sensors reference and GND for AiM CAN BUS.
Internally all GND pins are tied together but they are split in different pins, to eventually simplify the loom
connection.
The PDM32 may be turned ON in two distinct ways:
- Connect the IGN input to a switch: in this case the system, and all the devices, are powered
- Connect one of the two input channels CH_IN11 and CH_IN12 to VBatt, leaving the IGN input
OFF. In this case, the display is not turned ON, and you may choose which devices you wish to
activate. This may be useful for activating the Hazard or keeping a fan ON even with the engine
OFF until the temperature decreases till a defined value.
