Encoder alarm
-
Eye alarm code: 74 (for right drive motor encoder)
75 (for left drive motor encoder)
-
Alarm level: 1
-
Alarm cause: an encoder channel is disconnected, and motor is working.
In case of alarm follow this procedure:
1. Verify if the encoder is correctly connected to:
-
Motor itself
-
Ground : K1- 15 terminal
-
+ 5 V: K1- 14 terminal
-
A channel: K1- 37 terminal (for right drive motor encoder)
K1- 17 terminal (for left drive motor encoder)
-
B channel: K1- 36 terminal (for right drive motor encoder)
K1- 16 terminal (for left drive motor encoder);
2. if correctly wired, replace the encoder;
3. replace control board.
Alarm of motor thermal probe
-
Eye alarm code: 77 (for right drive motor thermal probe)
78 (for left drive motor thermal probe)
79 (for pump motor thermal probe).
-
Alarm level: 7
-
Alarm cause: Temperature difference between any two of the 3 motors results greater than
70 ºC
In case of alarm, follow this procedure:
1. verify if the wiring is correct;
2. replace the probe;
3. replace control unit.
