Off-Load Current Violation Detection

During off-load current monitoring, the power module measures as follows:

• Voltage measurement every 5 seconds
• Current measurement every 60 seconds An off-load current violation is detected if more than 80 milliamperes are measured.

If the power module detects an off-load current violation, a special off-load current monitoring function starts, as follows: The power module measures the instantaneous current value every 1.5 seconds for 8 minutes.

This gives the vehicle electrical system a period of time to restore normal off-load current.

If a current less than 80 milliamperes is detected for longer than 1 minute during the special off-load current monitoring, the special off-load current monitoring is restarted.

If the off-load current violation is still present after the special off-load current monitoring, the power module will send a warning to all control unit on terminals 30B, 30U, 30LM: These terminals are switched off: The power module issues the warning in the form of a message to the connected control units.
