5.5 3 xxxx
Continued
37053, Check the CMOS battery voltage level
Description
The CMOS battery on the computer board might be empty.
Consequences
After restart of the system, the system time will be reset.
The system will also use an erroneous setup or no restart will
be possible.
Probable causes
The system time has never been set. The CMOS battery is
faulty/empty.
Recommended actions
Set the system time, restart the system with power switch and
check if this event message is reported again. If this error is
reported again, replace the CMOS battery and set the system
time.
37054, Faulty computer unit fan
Description
The fans in the computer unit spin too slowly.
Consequences
No system consequence. The computer unit temperature will
rise.
Probable causes
Faulty fan, cabling or power supply. See the circuit diagram!
Recommended actions
Check the cabling to the computer unit fan. Check the fan.
Check the fan power supply. Replace the faulty component if
required.
37056, Cooling fan error
Description
Cooling unit fan has stopped or is rotating very slowly (Less
than arg rpm).
Recommended actions
Check the fan cables. Replace the fan.
37062, Computer module power supply warning
Description
The arg V voltage of the computer module power supply is arg
V, which is out of the allowed range.
Consequences
Continues on next page
178
Probable causes
The power supply unit, cabling, input voltage to the power
supply or the output load may cause the faulty voltage level.
See the Trouble Shooting Manual and circuit diagram!
Recommended actions
Check all cabling to the power supply unit. Measure the output
and input voltage levels. Replace the faulty unit if required.
37069, Faulty backup Power Supply
Description
The backup energy bank in the control module supplying the
backup voltage is faulty.
Consequences
After switching the power off, no system data changes will be
saved, unless "Shutdown main computer" has been done first.
Probable causes
This may be caused by a faulty backup energy bank, cabling
or charger.
Recommended actions
Do "Shutdown main computer" before turning the main power
off or wait until battery has been charged! Check the backup
energy bank cabling and connectors. Check the backup energy
bank. Check the power supply. Replace the faulty unit if
required.
37070, Overtemperature in Control Module Power
Supply
Description
The temperature in the control module power supply is too high.
Consequences
The system is shut down immediately.
Probable causes
This may be caused by poor cooling, too high a load on the
power supply or by a faulty power supply.
Recommended actions
Check the cooling fan. Check the output power. Replace any
faulty unit if required.
37074, Purge pressure too low
Description
Purge system number arg associated with manipulator interface
board (MIB) arg.
