3.7
- Error codes and alarm signals.
3.7.1
- 2 - EEPROM error.
Block due to software error. Replace the control board (543).
3.7.2
- 6 - Communication error on CAN-BUS, detected by control board (543).
Communication error between control board (543) and motor control board (232), or between
control board (543) and control panel (324), detected by MASTER control, on control board
(543). Perform the usual tests in case of failure of the CAN-BUS COMMUNICATION TEST in
par. 3.5.3.
3.7.3
- 9 - Communication error on the CAN-BUS between control panel (324) and
control board (543).
Communication errors on the CAN-BUS line detected by the PANEL control, on control
panel (324). Perform the usual tests in case of failure of the CAN-BUS COMMUNICATION
TEST in par. 3.5.3.
3.7.4
- 10 - Missing voltage and current at the power source output.
When the start command is activated, the circuits to detect the output voltage and output
current on the control board (543), detect voltage = 0 and current = 0. This situation is possible
only with the inverter broken (thus it does not generate the alternating voltage on the primary
circuit of the transformer (531)), or with one or both voltage and current detection lines
interrupted.
Perform the “open circuit operation” test in par. 3.5.8 and the “operation on resistive load”
test in par. 3.5.9.
3.7.5
- 13 - Missing communication between control board (543) and pre-charge board
(562).
This alarm is operative only at the power source start-up. The control board (543) check the
“MAINS” (mains voltage presence) and “PRECHARGE” (DC-capacitors (561) direct current
voltage) signals, coming from pre-charge board (562).
These signals can be checked on J7 of interface board (543):
−
“MAINS”
:mains voltage present = 0,1 Vdc, approx. on terminals 4(+) and 5(-).
−
“PRECHARGE” : DC-capacitors (561) voltage present = fig. 5.2.7 on terminals 7 and 8(gnd)
(in this waveform is more important the pulses regular presence than their
period and frequency).
Based on these signals, the control board (543) perform the following conditions:
“MAINS” “PRECHARGE”
absent
absent
= error 13 alarm.
present
absent
= error 16 alarm.
absent
present
= error 61 alarm.
present
present
= regular operation.
At the power source start-up, once detected the both signal presence, control board (543)
order the pre-charge relay closed, on pre-charge board (562) and set the power source for regular
operation. Starting from this moment error 13 alarm is no more operative.
Check the wiring between connectors J3 on pre-charge board (562) and J7 on interface board
(543), and replace the two boards if necessary.
