1.5.3 Timer Stop Connections
BNCOUI02.C02 0000206321 A.5 A.6 A.4 1/2/20 1:25 PM Released
This feature is not available on coin-operated machines. Timer stop is a feature of the E-P
Express
®
control which stops the machine timer while a certain input to the microprocessor is
grounded. When multiple machines without this feature are connected to a common chemical
supply system, the quantity of chemical injected can vary widely if two or more machines request
chemical simultaneously. When timer stop is properly wired with the chemical supply system, the
supply system stops the timers in certain linked machines when one machine requests chemical.
When the chemical injection is completed, the chemical supply system terminates the timer stop
command, and the stopped timers resume counting.
When the timer in a machine is stopped, the current formula event continues until the timer re-
sumes counting. If water valves are open when the timer stops, they will close when the desired
level is reached. Chemical injection signals will stop after the designated time, but the manifold
flush signal will not occur until the timer starts. All other actions (cylinder reversing, extract
speed, drain speed, etc.) that are in progress when the timer is stopped will continue until the tim-
er starts again and the programmed time for the current event expires.

provides two wires terminated with butt connectors in the rear console of the machine,
as shown in Figure 7: Timer Stop Connections, page 14 . One wire originates electrically from
pin 6 of M5 on the processor board. The other wire is electrically identical to pin 16 of M6 on the
processor board. For timer stop to operate, the chemical system should include a normally open
contact between these two connectors. When the contact is open, the machine runs normally.
When the contact is closed, the machine timer stops until the contact opens again.
