Doorlock Operation
When the Start button is pressed, and there is no payment required, the A1 controller checks that the S3
door switch is closed (detected by the U1 power module as a closed circuit between the two wires at U1,
CN13 (pins 1 and 2), Fig 7.1.
Fig. 7.2
If the S3 switch is detected as closed, U1 Power Module sends a brief 12VDC “lock pulse’ to the A111
doorlock on the CN13-6 (+12VDC) and CN13-4 (COM). The doorlock mechanically snaps to the locked
position, locking the loading door and closing the 2-pole S4 interlock switch inside the doorlock assembly,
Fig 7.3.

The S4 switch closure in the doorlock sends line Voltage back to the U1 Power module connector CN2
(this is referred to as the “interlock” signal), confirming that the doorlock has activated. The wash program
then continues, Fig. 7.4.
