(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 substituite 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 substituite the Controller.
5) LOGIC FAILURE #3
MDI-PRC Code = 17
- Cause: It occurs when the circuit to limitate 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 substituite the Controller.
6) CHECK UP NEEDED
MDI-PRC Code = 99
- Cause: This is just a warning to call for the time programmed
maintanance.
- Remedy: It is just enough to turn the CHECK UP DONE option to level
ON (see 12.4.2.17) after the maintanance is executed.
14.1.2 Two Blinks Alarms
1) INCORRECT START
MDI-PRC Code = 79
- Cause: This is just a warning for an incorrect starting sequence.
- Remedy: The possble 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, substituite 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 substituite the controller.
3) HANDBRAKE
MDI-PRC Code = 71
- Cause: This alarm occurs when the operator try to travel with the
handbrake active.
