At the next travel request the warning disappear.
13) “CURRENT GAIN”
Cause:
The Maximum current gain parameters are at the default values, which means
the maximum current adjustment procedure has not been carried out yet.
Troubleshooting:
Ask the assistance of a Zapi technician to do the correct adjustment procedure
of the current gain parameters.
14) “WAITING FOR NODE”
Cause:
The controller receives from the CAN the message that another controller in the
net is in fault condition; as a consequence the ACEX / COMBIACX controller
itself cannot enter an operative status, but has to WAIT for the other controller
coming out from the fault status.
15) “DRV. SHOR. EV1”
Cause:
Electrovalve EV1 driver is shorted.
Troubleshooting:
Check if there is a short or a low impedence between the negative of one of
those coils and –BATT. Otherwise the driver circuit is damaged and the
controller must be replaced.
16) “DRV. SHOR. EV2”
Cause:
Electrovalve EV2 driver is shorted.
Troubleshooting:
Check if there is a short or a low impedance between the negative of this coil
and –BATT. This warning occurs also if the external load is not present and the
parameter EV2 in the “Set Options” menu is set “PRESENT”, in this case the
warning disappears setting the EV2 parameter “ABSENT”. Otherwise the driver
circuit is damaged and the controller must be replaced.
17) “DRV. SHOR. EV3”
Cause:
Electrovalve EV3 driver is shorted.
Troubleshooting:
Check if there is a short or a low impedance between the negative of this coil
and –BATT. This warning occurs also if the external load is not present and the
parameter EV3 in the “Set Options” menu is set “PRESENT”, in this case the
warning disappears setting the EV3 parameter “ABSENT”. Otherwise the driver
circuit is damaged and the controller must be replaced.
18) “CONT. DRV. EV”
Cause:
One or more on/off valve drivers is not able to drive the load (cannot close).
Troubleshooting:
The device or its driving circuit is damaged, replace the controller.
19) “PUMP I NO ZERO”
Cause:
In standby condition (pump motor not driven), the feedback coming from the
current sensor in the pump chopper gives a value out of a permitted range,
