4 Component Operation and Maintenance
This section of the manual describes the normal operating procedures and basic troubleshooting and
repair techniques for each of the system components. The following procedures are designed to
provide you with the hardware troubleshooting and service information you need in order to provide
your customers with the highest quality service possible.
When troubleshooting any issue, verify that the power supply is providing power to the affected
component.
Note: Only trained technicians should perform maintenance or repair procedures.
4.1 Pay Node
A pay node is located in each Card Terminal and Receipt Printer. It consists of an LCD screen, a
circuit board, wiring, and a metal enclosure.
4.1.1 Running a Self Test
Use the Self Test card (that was supplied with the WashPay System) to run a test on the Card
Terminal Pay Node. Swipe the card once to enter the Self Test mode and swipe the card again to exit
Self Test. The Card Terminal will exit Self Test and restart. The following data will be listed:
• STOP key – This test checks three outputs on the pay node:
o Bay Power – The second press will energize the Power Relay for 5 seconds.
o Coin Power – the third press will energize the Coin Acceptor Power Relay.
o The next press will repeat the cycle.
Note: When running this test, the Coin Acceptor Power Relay will be de-energized when the Bay
Power test is active. The Coin and Bill Acceptors will be disabled, if they are powered through this
relay. To re-enable the Coin and Bill Acceptors, either exit and re-enter the Self Test, or press the
STOP button until the Coin Power test is active.
• Input 1 – The number of pulses generated by the device connected to the Coin 1 input will be
displayed along with the pulse width of the last pulse. The pulse width displayed will be the
pulse width that the pay node sees. It will be different from the actual pulse width generated
by the acceptor because of the time delay associated with the input circuitry of the pay node.
Note: The pulse count is a two-digit cumulative counter. After reaching 99, the next pulse will
reset the counter back to 00.
• Input 2 – The number of pulses generated by the device connected to the Coin 2 input will be
displayed along with the pulse width of the last pulse. The pulse width displayed will be the
pulse width that the pay node sees. It will be different from the actual pulse width generated
by the acceptor because of the time delay associated with the input circuitry of the pay node.
