In case of low battery alarm, follow this procedure:
1. measure battery voltage with a tester and, if different from the value reported on
COMPACT display, replace main board;
2. otherwise recharge battery.
Drive motor overtemperature
-
Eye alarm code: 13 for right drive motor
19 for left drive motor
-
Alarm level: 5
-
Alarm cause: The measure of drive motor temperature exceeds 155 ºC..
In case of alarm, follow this procedure:
Presence of alarm with cold motors:
1. with a handheld multimeter (in resistance operating mode) you have to measure a
resistance of about 10 kohm between the two wires of the temperature probe ( execute the
measure at ambient temperature of 25°C).
If the measure is not correct it is necessary to replace the temperature probe.
2. disconnect the temperature probe and check the wiring insulation between signal wire
and ground wire (towards control board);
3. replace control board.
Presence of alarm with hot motors:
1. If temperature value (you can read it from display or via PC) seems correct, verify if the
motor stator case are clean
