undervoltage threshold is 9,5V.
Troubleshooting
of fault displayed at startup or in standby; in these cases it is
very likely the fault is due to an undervoltage, so it is suggested to check:
A) Key input signal down-going pulses (below undervoltage threshold) due to
external loads, like DC/DC converters starting-up, relays or contactor
switching, solenoids energizing / de-energizing.
B) If no voltage transient is detected on the supply line and the alarm is present
every time the key is switched ON, the failure is probably in the controller
hardware, so it is necessary to replace the controller.
Troubleshooting
of fault displayed during motor driving; in this case it can be an
undervoltage or a overvoltage condition.
A) If the alarm happens during traction acceleration or driving hydraulic
functions, it is very likely it is an undervoltage condition; check battery
charge condition, power cable connection.
B) If the alarm happens during release braking, it is very likely it is due to
overvoltage condition; check line contactor contact, battery power cable
connection.
14) “LOGIC FAILURE #2”
Cause:
Fault in the hardware section of the logic board which manages the phase’s
voltage feedback.
Troubleshooting:
This type of fault is not related to external components, so when it happens it is
necessary to replace the Controller.
15) “LOGIC FAILURE #3”
Cause:
Hardware problem in the logic card circuit for high current (overload) protection.
Troubleshooting:
This type of fault is not related to external components, so, when it is present it
is necessary to replace the controller.
16) “STBY I HIGH”
Cause:
The current transducer or the current feedback circuit is damaged in the
controller.
Troubleshooting:
This type of fault is not related to external components so, when it is present, it
is necessary to replace the controller.
17) “WRONG BATTERY”
Cause:
At start-up, the controller checks the battery voltage and verify it is within a
window around the nominal value.
Troubleshooting:
A) Check that the controller SET BATTERY parameter value matches the
battery nominal voltage.
B) Check that the TESTER MENU / BATTERY VOLTAGE parameter shows
same value as the battery voltage measured with a voltmeter. If it is does
not match, then do a “ADJUST BATTERY” function.
C) Replace the battery.
18) “ANALOG INPUT”
