INCORRECT
START
Incorrect
starting
sequence
This alarm signals an incorrect starting sequence.
Possible causes:
D) Direction switch is turned off before truck starting
E) Error in sequence made by operator
F) Incorrect wiring
D) If the default persists, replace the controller

ENCODER ERROR Encoder error Two consecutive readings of the encoder speed are two
much deferent in between: because of the inertia of the
system it is not possible the encoder changes its speed a
lot in a short period .Probably an encoder failure has
occurred (e.g. one or two channels of the encoder are
corrupted or disconnected).Check both are electric and
the mechanical encoder functionality. Also the
electromagnetic noise on the sensor bearing can be a
cause for the alarm.

SEAT MISMATCH Seat switch
signal fault
If the “SAFE OUT CONFIG” is 1 and the fault may
alarms. When traction seat switch signal is different
from the pump controller switch signal, the fault
alarms. Check the seat switch wiring.

WAITING FOR
NODE
Wait for node
signal
One controller receives a signal that the other signal can
no t work normally and the controller is under waiting
condition until all CAN bus are ok. Check the unable
communicating module wiring; check its software
edition and programming.

WATCHDOG #1 Watchdog
fault 1
The watchdog is activated before the software is started
when starting. The watchdog signal is out of effect in
spare use or travelling condition.
Watch dog hardware electric circuit or microcontroller
output part are damage. Change the controller.

WATCHDOG #2 Watchdog
fault 2
The watchdog is activated before the software is started
when starting. The watchdog signal is out of effect in
spare use or travelling condition.
Watch dog hardware electric circuit or microcontroller
output part are damage. Change the controller.

SAFETY
INPUT
Safety input
fault
When the safety input switch is open, the main
contactor opens and electromagnetic or auxiliary output
coil is driven. Check if the connection of A11 is correct.
If all outskirt is all right, change the controller.
