handbrake active.
- Remedy: Check the handbrake switch and its wiring to CNA#13. The
handbrake switch must be connected between CAN#13 and
GND voltage. When it is closed to GND the handbrake is
considered active. A failure in the logic is possible too. In this
case it is necessary to replace the controller.
4) LIFT+LOWER
MDI-PRC Code = 90
- Cause: This alarm occurs when both a Lifting request and a Lowering
request are active at the same time.
- Remedy: If the MDI-PRC is absent, check only the wiring of the main
Lifting/Lowering pair (CNB#8 and CNB#9); if the MDI-PRC is
present check also the wiring of the Aux Lifting/Lowering pair
(CNA#14 and CNA#15). (Use the readings in the TESTER to
facilitate the troubleshooting).
A failure in the logic is possible too. When you have verified the
Lifting/Lowering switches are fine working and the wiring is
right, it is necessary to replace the controller.
5) LIFT LOW ACTIVE
MDI-PRC Code = 91
- Cause: This is just a warning when a Lifting/Lowering request is active
at key-on.
- Remedy: The possible reasons for this alarm are (use the readings in the
TESTER to facilitate the troubleshooting):
- When MDI-PRC is absent: at least one between LIFTING
SWITCH (CNB#9) or DESCENT SWITCH (CNB#8) active at
key on.
- When TRUCK TYPE is Level=1: at least one between
LIFTING SWITCH (CNB#9), DESCENT SWITCH (CNB#8),
DIGITAL INPUT#1 (CNA#14) or DIGITAL INPUT#2
(CNA#15) active at key-on.
- When TRUCK TYPE is Level=2: at least one between
LIFTING SWITCH (CNB#9) or DESCENT SWITCH (CNB#8)
active at key-on.
- When TRUCK TYPE is Level=3: at least one between
LIFTING SWITCH (CNB#9) or DESCENT SWITCH (CNB#8)
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.
11.1.3 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
