CTEK MULTI XS 3600 Troubleshooting Guide

Trouble Shooting Guide 23
• The Power LED is flashing rapidly or glowing faint.
Explanation: The charger has entered power save mode due to low voltage.
There is no charger or alternator turned on for the supply battery.
• The SmartPass does not start charging.
Explanation: In order to start charging the supply voltage needs to be above
13.1V. The voltage on the target battery also needs to above 5V.
Test: Test Use a voltmeter to verify that the voltages are within the levels
specified above.
• The SmartPass does not stop charging the target battery even though the
alternator or charger on the supply battery has been turned off
When charging of the supply battery is turned off the voltage will drop. The
SmartPass will turn off when the voltage has dropped below 12.8V, if there are
no parallel loads this will take some time.
• The SmartPass does not supply the consumers from the consumer battery.
The SmartPass will turn off the consumer output if the consumer battery
reaches 11.5V. This will prevent the battery from being damaged due to being
drained too much. To turn on the consumer output again the consumer battery
needs to be charged.
• Is lit.
Explanation: The SmartPass has detected a problem. This LED is always lit
with some other LEDs flashing to tell what the problem is.
Led 1 flashing: A problem is detected with the service battery. The current to
the battery is too high or the SmartPass is overheated. If the current is too
high the SmartPass will try to start charging the battery five times. If all five
tests fails the SmartPass needs to be disconnected from both batteries before
it can restart. If this is the case check the cables for short circuit. If the
SmartPass is overheated charging will automatically restart when the
temperature has dropped.
Led 2 flashing: A problem is detected with the consumer output, while the
consumer output is connected to the starter battery input. The current to the
output is too high or the SmartPass is overheated. If the current is too high the
SmartPass will try to start charging the battery five times. If all five tests fails
the SmartPass needs to be disconnected from both batteries before it can
restart. If this is the case check the cables for short circuit, there could also be
too many consumers connected. If the SmartPass is overheated output will
automatically turn on when the temperature has dropped.
