i) < DRIVER SHORTED >
Cause:
The driver of the main contactor coil is shorted.
Troubleshooting:
● Check if there is a short or a low impedance pull-down between NMC (CNA#26)
and –BATT.
● The driver circuit is damaged in the controller, which has to be replaced.
j) < NO FULL COND. >
The test is carried out in full conduction. If, in this condition, the VMN is found to
be greater than 1/3 VBATT, the diagnostic circuit is faulty, causing a safety risk, and thus
machine operation is inhibited. If the defect persists, replace the logic.
k) < CAN BUS KO >
Cause:
No Can messages received by the HP CAN microcontroller from other devices
(CAN BUS nodes).
Troubleshooting:
This alarm could be caused by a can bus malfunctioning, which blinds
communication. Otherwise it is an internal fault of the controller which must be replaced.
(3) Common fault for ZAPI instrument system (The second line of instrument indicates
“ON NODE 16”)
Table 4-8 Common fault for instrument system
Trouble is in the internal memory to store and
regulate the parameters. Machine will automatically
stops in case of trouble. The controller should be
changed if the trouble still exists after reconnection
when the electric lock is turned off. If the trouble
disappears, the parameters stored before will be
replaced with default value.
