Section 3 Troubleshooting
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.
• Close steam valve to steam tumbler before servicing.
• Never start the tumbler with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the tumbler is properly grounded.

Step Problem If No, then
1 Is there voltage across the primary of the transformer?
If yes, continue to next step.
Correct wiring between transformer and supply voltage.
Check fuses.
2 Is there voltage across terminals 2 & 3 of the transformer
secondary? If yes, continue to next step.
Replace transformer.
3 Is there voltage to the COM of the door switch?
If yes, continue to next step.
Correct wiring to door switch. Check fuses.
4 Is there voltage to the N.O. terminal of the door switch?
If yes, continue to next step.
Correct wiring and check fuses.
5 Is there voltage to H2-8 terminal of micro control?
If yes, continue to next step for forward rotation, or step 11
for reverse rotation.
Correct wiring between micro control and door switch.
6 Forward Rotation: Is there voltage to H2-3 of micro
control? If yes, continue to next step.
Make sure unit is in the forward portion of rotation.
Replace micro control.
7 Is there voltage across the coil of the forward relay?
If yes, continue to next step.
Correct the wiring to the relay.
8 Is there voltage to terminals L1, L2 and L3 of the forward
relay? If yes, continue to next step.
Correct wiring between relay and supply voltage.
9 Is there voltage to terminals T1, T2 and T3 of the forward
relay? If yes, continue to next step.
Replace forward relay.
10 Is there voltage across L1, L2 and L3 of the motor?
If yes, continue step 16.
Correct wiring between motor and forward relay.
11 Reverse Rotation: Is there voltage to H2-4 of micro
control? If yes, continue to next step.
Make sure unit is in the reverse portion of rotation.
Replace micro control.
12 Is there voltage across the coil of the reverse relay?
If yes, continue to next step.
Correct the wiring to the relay.
13 Is there voltage to terminals X, Y and Z of the reversing
relay? If yes, continue to next step.
Correct wiring between relay and supply voltage.
14 Is there voltage to terminals U, V and W of the reversing
relay? If yes, continue to next step.
Replace reversing relay.
15 Is there voltage across L1, L2 and L3 of the motor?
If yes, continue to next step.
Correct wiring between motor and reversing relay.
16 Does the motor turn? If yes, continue to next step. Replace motor.
17 Does the cylinder rotate? If yes, continue to next step. Check drive components between motor and cylinder.
18 Unit operational.
