F.3.19 +14V under range
The system control board PC1 +14V power supply is out of range,
less than 12V (if it is less than 10V, the system control board is
off). In the range between 12V and 16V no alarms are generated.
This power supply is coming from the PFC board PN1 and it is con-
trolled by the microprocessor of the system control board PC1.
Verify the value of the power supply on the test points TP4 and TP2
(GND) on the PFC board PN1; on the test points TP7 and TP1 (GND)
on the system control board PC1; by checking the LED H1 (ON=OK,
OFF=NOT OK) always on the system control board PC1.
Possible causes:
1.
check if fuses F3 and F1 on the PFC board PN1 are blown.
2.
PFC board PN1 defective.
3.
system control board PC1 defective.
If the host computer PC1 needs to be replaced, re-
member to remove the EEPROM D38 from the old
board and mount it on the new one, otherwise all
the following parameters will be lost:
If you forget to do this, recover the information from
the System Configuration Chart (see Section C).
The alarm is captured and stored as soon is detected.
Press the RESET pushbutton on the control panel to cancel the
alarm (if expired).
