41:3 ACTUATOR CIRCUIT
The DLCU on I/O board type 10 continuously controls the circuit to the door lock solenoid. DLCU
can detect an open circuit (>50 kΩ) but not a short circuit.
If case of an open circuit, CPU will show the error.
The error will disappear if the error is removed.
Possible causes:
• Open circuit to the door lock solenoid.
• Open circuit in the door lock solenoid.
• Error or open circuit in the I/O board 10 circuits.
Recommended actions:
1. Check resistance in door lock solenoid circuit. Correct reading is approx. 6 Ω.
2. Check if error "AC" still remains in DLCU status.
For pocket machine, this error relates to I/O board type 10 on "Loading side".
See also corresponding error 41:23 for I/O type 10 on "Unloading side".
41:21 CHARGE CIRCUIT
Only on Pocket washer.
Pocket washer uses two I/O boards type 10, one for the "Loading side" and one for the "Unloading
side".
This error relates to I/O board type 10 on "Unloading side".
See also corresponding error 41:1 for I/O type 10 on "Loading side".
The DLCU on I/O board type 10 contains an arming circuit that is charged when the door lock coil
is to be activated. For safety reasons, this arming circuit must be discharged when the door lock
coil is not to be activated. If the arming circuit for operating the door lock is charged when it is not
supposed to be, an error message will be sent to the CPU.
CPU reads the error message when the door is locked and unlocked and generates an error. The
error is ignored between these two occasions.
Possible causes:
• The error can bee caused by overloads and/or defective components in the DLCU on I/O
board type 10.
