19) MOTOR TEMPERATURE
This warning is signalled if right or left or both motors temperature switches
open (digital sensor) or if the analog signals overtakes the cut off level. If it
happens when the motor is cold, check the wiring. If all is ok, replace the
logic board.
20) BATTERY LOW
If the "battery check" option is ON, a battery discharge algorithm is carried
out. When the charge level is 20% , this alarm is signalled and the current is
reduced to the half of the programmed level.
21) VACC NOT OK
The test is made in standby. This alarm indicates that the accelerator voltage
is 1 V greater than the minimum value programmed by the PROGRAM
VACC function.
Possible causes:
A) the potentiometer is not correctly calibrated;
B) the potentiometer is defective.
22) INCORRECT START
This alarm signals an incorrect starting sequence. Possible causes:
A) Fw or Rev or Enable microswitch failure;
B) error in sequence made by the operator;
C) incorrect wiring;
D) if the default persists after checking the harness, replace the logic.
23) FORW + BACK
The test is carried out continuously. An alarm is signalled when a double
running request is made simultaneously. Possible causes:
A) defective wiring;
B) running microswitch failure;
C) incorrect operation;
D) if the defect persists, replace the logic.
24) THERMIC SENSOR KO
The range of inverter temperature sensor is always checked and a warning is
signalled if it is out of range.
When this alarm is signalled, the maximum current of the controller is
reduced to half.
25) WAITING FOR NODE #4
The Slave has detected a failure, the Master cannot close the main contactor
because of the alarm status of the Slave (which the Master knows by the
CAN-BUS line). The failure must be looked for in the Slave controller, use the
remote console to get connection to the Slave µC.
26) WAITING FOR NODE #3
The Master µC has detected a fault condition, the Slave is aware of this
thanks to canbus communication; it cannot drive the motor until the Master
has resolved its problem. The fault has to be looked for in the Master.
27) NO CAN MESSAGE #4
Master (node #3) signals that it has lost can communication with the Slave
(node #4). This fault could be determined by a problem in the truck canbus
line or by an internal problem in the controller logic card.
It is suggested to preliminary check canbus connection.
28) NO CAN MESSAGE #3
Slave (node #4) signals that it has lost can communication with the Master
(node #3). This fault could be determined by a problem in the truck canbus
line or by an internal problem in the controller logic card.
It is suggested to preliminary check canbus connection.
