18) MOTOR TEMPERATURE
This warning is signalled if the motor temperature switch opens digital sensor
or if the analog signal overtakes the cut-off level. If it happens when the
motor is cold, check the wiring. If all is OK, replace the logic board.
19) 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, check the connection of the sensors.
20) CAN BUS KO
The diagnosis of the CAN-BUS line is present only if the inverter uses this
link (depends on the software version). It is signalled if the inverter does not
receive any message from the CAN-BUS line. First of all, check the wiring. If
it is ok, the problem is on the logic board, which must be replaced.
21) SAFETY
This alarm is signalled when the "SAFETY" input is open. The "SAFETY"
circuit gets active and opens the drivers of LC and EB and stops the
machine. Verify the “SAFETY” input connection.
22) BATTERY LOW
If the "battery check" option is ON, a battery discharge algorithm is carried
out. When the charge level is 10%, this alarm is signalled and the current is
reduced to the half of the programmed level.
23) WRONG SET BATT.
When the key is turned ON, the controller check the battery voltage and
verifies it is within a window around the nominal value. Replace the battery
with a correct battery.
24) WAITING FOR NODE
The controller receives from a remote module via CAN Bus the information
that it isn’t possible to close the LC (the module isn’t ready locked in an alarm
state). Verify the other modules to determinate in which of them there is the
problem.
