AE0ZP0EC - AC-0 SSL SENSORED - User Manual
(e.g. when the pump inrush current makes the battery
temporary collapsed).
So first of all check for your failure mode then contact the Zapi
technician to look for a countermeasure.
As a matter of fact this alarm may occurs also for a HW failure
and, in this case, it is necessary to replace the Controller.
4) LOGIC FAILURE #2
MDI-PRC Code = 18
- Cause:
It occurs when the circuit, to compensate for the dead times of
the sine waves, is failed.
- Remedy:
It is necessary to replace the Controller.
5) LOGIC FAILURE #3
MDI-PRC Code = 17
- Cause:
It occurs when the circuit to limit via HW the current peak in the
controller is active.
- Remedy:
It is probably a power failure or a logic failure. If it occurs
permanently it is necessary to replace the Controller.
6) CHECK UP NEEDED
MDI-PRC Code = 99
- Cause:
This is just a warning to call for the time programmed
maintenance.
- Remedy:
It is just enough to turn the CHECK UP DONE option to level
ON (see “Adjustments” submenu) after the maintenance is
executed.
12.1.2 Two Blinks Alarms
1) INCORRECT START
MDI-PRC Code = 79
- Cause:
This is just a warning for an incorrect starting sequence.
- Remedy:
The possible reasons for this alarm are (use the readings in the
TESTER to facilitate the troubleshooting):
a) Error in sequence made by the operator
b) Incorrect wiring
c) The seat switch active at key-on
A failure in the logic is possible too. When all of the above
conditions were checked and nothing was found, replace the
controller.
12.1.3 Three Blinks Alarms
1) CAPACITOR CHARGE
MDI-PRC Code = 60
- Cause:
In working condition, a resistance connected between the key
and the Rail Capacitors, keeps the Rail Capacitors charged
before the Main Contactor closes. When the voltage on the Rail
Capacitors (measured on the phase V) is low and does not
increase when the main contactor is opened this alarm occurs.
- Remedy: Three
possibilities:
- Another device, connected in parallel with the Rail
Capacitors, has a failure
- At least a motor phase is not connected to the controller or
broken.
- A Power failure or a Logic Failure occurred in the controller.
