2-29 JC DIAG A1208 COMPRESSION CONTROL FAILURE
Diagnostic for:
122/008 error code (CAN code is 0x5026) overcurrent error
•
First make a visual check of the motor cabling and its connection to the Compression Board.
•
Disconnect the cable W301 from connector J3.
-
Check on the cable connector for a short circuit. If you find one, change the compression motor +
e cables (see
Job Card D/R A244 - Compression Motor with Encoder and Compression
).
-
Measure the motor coil impedances. The impedances must measure 2 ohm between the blue
and pink wires, 2 ohm between the yellow and red wires. If not, change the motor + e
cables(see
Job Card D/R A244 - Compression Motor with Encoder and Compression Belt
).
•
If the error persists, change the Compression Board (see
Job Card D/R A250 - Compression Board
). Check the movement.
•
If the error persists, change the compression motor unit (see
Job Card D/R A244 - Compression

2-30 JC DIAG A1212 COMPRESSION BRAKE FAILURE
Diagnostic for:
122/020 error code (CAN code is 0x500D) brake error
•
Check the B303 screw brake cable (W309) and brake coils by measuring the brake resistance. The
nominal resistance value is 192 ohm (+/-10 ohm). If the resistance values are out of these limits
change the brake and cables (see
Job Card D/R A247 - Motorized Compression Brake
•
Check the connector J5 on the Compression Board for damage. If damage is found, change the
Compression Board (see
Job Card D/R A250 - Compression Board
).
•
Check the compression brake cable (W318) and brake coils by measuring the brake resistance. The
nominal resistance value is 230 ohm (+/-10 ohm).
If the resistance is out of these limits, change the brake and cables (see
).
•
If the error persists, change the Compression Board (see
Job Card D/R A250 - Compression Board
