MAINTENANCE
8.1
ANNUAL INSPECTION
8.1.1
General
In addition to these instructions, you must observe the instructions for maintenance in the
Manual
for monitoring unit PCM2
and the battery manufacturer's maintenance instructions.
8.1.2
Check of charging voltage
Connect a measuring instrument to the voltmeter terminal (see section 5.5
). Check that the rectifier's output voltage corresponds to the set value.
If the float charging voltage is temperature controlled, it is difficult to determine what the expected
output voltage should be. The solution is to temporarily shut down the temperature control. You
do this using the menu option
Functions, battery temperature
to specify that the temperature
sensor is not installed (see the
Manual for monitoring unit PCM2
, section on
Operation, Functions
).
Do not forget to reset the parameter for the installed temperature sensor following a completed
measurement!
All control is based on measurement. If charge voltage is found to be in a state of non-
conformance it is therefore the voltage measurement that should be calibrated, see the instructions
for maintenance in the
Manual for monitoring unit PCM2
.
8.1.3
Check of cooling capacity
Check that the ventilation openings for the equipment and the individual rectifier modules are not
clogged with dust or other contamination. Clean where necessary.
