Fast & Flexible Chip Shooter DECAN F2 Service Manual
17.3.14. Main power supply not applied (E12)
E1200 Short-circuit occurred because the main circuit breaker power cable(MS1~6) is not
secured properly
[Cause]
Short-circuit occurred because the main circuit breaker power cable(MS1~6) is not
secured properly
[How to Check]
Check whether the power supply is turned off when turning on the MCCB
Check the cause of the automatic turn-off of the power supply. (Check the assembling
state of the MCCB power cable)
Check the CP1, 2 and 3 in order
[Measures]
Reassemble the MCCB power cable.
Check the CP1, 2 and 3 in order.
E1201 Defective PC power supply
[Cause]
Defective PC power supply (internal short-circuit presumed)
[How to Check]
Check the input voltage (220V) of the PC power supply (when it is not applied, check
the MCCB and CP)
Check the output voltage (5V, 12V) of the PC power supply (when it is not outputted,
replace the power supply)
[Measures]
Replace the PC power supply unit.
Cause Description Remarks
Main power supply
not applied
Short-circuit occurred because the main circuit
breaker power cable(MS1~6) is not secured properly
E1200
Defective PC power supply E1201
Leakage current occurred due to short-circuit
between ground wire and power supply cable
E1202
PC power supply unit is damaged after a power
outage occurred at the factory
E1203
Main power supply is not inputted E1204
17-83
Troubleshooting
E1202 Leakage current occurred due to short-circuit between ground wire and power supply
cable
[Cause]
Leakage current occurred due to short-circuit between ground wire and power supply
cable
[How to Check]
Check whether a short circuit occurred between each phase with a tester
[Measures]
Remove the power supply connector immediately and open the rear lower panel to
check whether a short circuit occurred between phases. Find the cause of the short
circuit to solve the problem and supply power to the machine again.
E1203 PC power supply unit is damaged after a power outage occurred at the factory
[Cause]
PC power supply unit is damaged after a power outage occurred at the factory
[How to Check]
Check the operation of the DC fan in the rack
Check the input and output of the power supply
Replace the PC power supply
[Measures]
Replace the PC power supply unit
E1204 Main power supply is not inputted
[Cause]
Main power supply is not inputted
[How to Check]
Check the input power at the MCCB
Check the output power from the AVR or power supply panel
Inform the customer of such problems and measures
[Measures]
Check the input power of the MCCB.
Check the output power from the AVR or power supply panel.
