Zapi AC-0 SSL User Manual

AE0ZP0EC - AC-0 SSL SENSORED - User Manual Page - 81/100
(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.
11.1.2 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) A travel demand active at key on
b) The tiller switch active at key-on
c) The H&S input active at key-on
d) The Quick inversion 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.
2) FORW+BACK
MDI-PRC Code = 80
- Cause: This alarm occurs when both the travel demands (Fwd and
Bwd) are active at the same time.
- Remedy: Check the wiring of the Fwd and Bwd travel demand inputs (use
the readings in the TESTER to facilitate the troubleshooting).
A failure in the logic is possible too. When you have verified the
travel demand switches are fine working and the wiring is right,
it is necessary to replace the controller.
3) HANDBRAKE
MDI-PRC Code = 71
- Cause: This alarm occurs when the operator try to travel with the
