2-49 JC DIAG A1503 OVERCURRENT FAILURE
Diagnostic for:
152/007 error code (CAN code is 0x3201) Current error
•
Check that the W109/111/113 shunt cable resistor R101 (0.01 Ohm) and its connections are good.
If not, change it.
There are two different circuits.
1. High Power.
The motor drive current flows here only during lift or rotation motions. In the neutral position, the cur-
rent is less than 10 mA on the W210 cable (for lift and rotation).
If the current is more than this value, measure the current on W211 (for rotation). Change the appro-
priate board or the W211 cable.
-
Check the following connections:
W210 Lift Board - J1
W211 Lift Board - J12
Rotation Board - J1
-
Measure current on cable W210 while performing a rotation movement. It must be less than 20 A.
-
If it is more than 20 A, change the Rotation Board (
Job Card D/R A221 - Rotation Board
).
-
Measure current on cable W210 while performing a lift movement. It must be less than 20 A.
-
If it is more than 20 A, change the Lift Board (see
Job Card D/R A201 - Lift Board
).
2. Low Power.
Measure current on cable W110. It must be less than 2 A. If it is more than 2 A, check the following
cables, and connectors:
-
W116; J7 on PDU Board PL101 to J1 on Interface Board PL104.
-
W315; Arm distribution board J2 to PDU Board J6.
-
W310; Arm distribution board J4.
-
W313; Compression Board J9.
-
W307; Compression Board J1 to Arm distribution board J5.
-
W209; PDU Board J7 to Lift Board J2
-
W212; Lift Board J13 to Rotation Board J2
