Connecting to Central Pay System
IMPORTANT: Any central pay device and related
installation wiring that is connected to the washer
must maintain the Electromagnetic Compatibility
(EMC) of the washer in order to comply with the
appropriate national EMC regulatory
requirements. The central pay device and related
wiring, as a minimum, must meet the emission
requirements of EN55014-1 and the immunity
requirements of EN55014-2.
Start Pulse Input Wiring Connections
Use 511478 Remote Vend Wire Harness, supplied in
accessories bag, to connect input to control
(pin 1 – black; pin 2 – red).
The start pulse is an open collector input to the control.
The start pulse input is active when the input of the
H11L1 optocoupler is energized. The start pulse is
considered valid if it is at least 15 msec. in length with
a maximum length of 1 sec. The minimum time
between start pulses is 25 msec. The minimum active
input current for a start pulse is 3 mA and the
maximum active input current is 30 mA. Refer to
wiring diagram for connections to control.
Available Output Wiring Connections
Use 511478 Remote Vend Wire Harness, supplied in
accessories bag, to connect output to control
(pin 3 – white/red; pin 4 – orange/black).
The available output is opto-isolated with an open
collector device (4N25) that provides a signal to an
external vending device such as a central pay system.
When active it indicates that the washer is not
currently in use and is available to use. The available
output is limited to 5 mA maximum at 28 VDC
maximum. Refer to wiring diagram for connections to
control.
NOTE: Wiring to the central pay system should
exit machine through hole in rear of control
cabinet. Refer to
