Fault: Failure on the +15 voltage.
Description: The supervision of the +15 voltage indicates that the voltage is outside
specified limits (13.8 – 16.2 V). Alarm 510 is generated.
What to do:
1.
Check if +15 V / -15 V / +5 V is available at P59 on PC 1675 Power Supply,
see below.
2.
If +15V / -15V / +5 V is not available, disconnect the Power Supply cable at
P82 on PC 1753 DC/DC Converter and repeat the voltage check at P59:
3.
If the voltage still is not available, replace PC 1675 Power Supply.
4.
If the voltage now is available, replace the Communication Interface
(CPS/IDS).
5.
Replace PC 1672 Control Panel.
Checking voltages
• Open the Power & Communication Interface.
• Disconnect the battery cable.
• Disconnect the Power Supply cable at P59 on PC 1675 Power Supply.
• Connect the mains power cable to the AC/DC Converter cable.
Caution: With mains power connected to the unit, there are energized electrical
components inside the equipment. All personnel must exercise extreme caution when
in the vicinity of this equipment if fault tracing or adjustments are performed with mains
power supply connected and with the battery drawer opened.
• Switch the KION workstation to Standby.
• Check the voltage levels in connector P59 on PC 1675 Power Supply.
Fault: Failure in the -15 voltage
Description: The supervision of the -15 voltage indicates that the voltage is outside
specified limits (-13.8 V – -16.2 V). Alarm 510 is generated.
What to do: Refer to Diagnostic Log 042
Information: Hardware failure has been solved. Technical alarm has been sent before
this diagnostic log.
What to do: Power cycle the system and check that the technical alarm is gone.
Fault: Failure in the Power switch detected.
Description: The Power switch is toggling between the system states without being
stable in the selected state.
What to do: Check / replace the power switch
