GS-401 Timer Basics
Checking Power to the Timer
Using a voltmeter, check the AC voltage to the timer.
There should be 24 to 28 volts AC across terminals 1
& 3 at all times; the same voltage should be across
terminals 2 & 3 when the timer is running.
Bypassing the Timer
In order to bypass the timer connect a jumper wire
across terminals 1 & 2. This will mimic the timer
being on.
Starting the Timer
Touch and release a jumper wire
across terminals 1 & 4. Each
touch and release simulates a coin
being put in to the coin acceptor.
The timer should start when the
number of touch and releases
equals your coins to start.
Stopping the Timer
Press Mode Button until LED is lighted next to
Reset/Cancel.
Press the Decrease/Cancel button.

Timer will Not Start
Follow the “Coins to Start” instructions and verify that it is correct for your
installation. The Coins to Start might be set higher than the desired amount.
If the timer doesn't work after performing the previous two test then the timer might be bad, replace the timer.
The Coins to Start is not set correctly.
Timed Hot (terminal 2) and 24 VAC
Common (terminal 3) is shorted.
Coin switch on the coin acceptor is
shorted or a wire is shorted across
terminals 1 & 4 or 1 & 5.
Remove all wire(s) from terminals 4 & 5. Try to turn on the timer by
following the “Starting the Timer” instructions. If the timer starts then you
may have a shorted output on your coin acceptor or a short in the wiring.
Remove all wire(s) from terminal 2 and start the timer by following the
“Starting the Timer” instructions. Now check the voltage across terminals 2
& 3 with a voltmeter to verify the timer is on. If the timer starts with the
wire(s) off terminal 2 then there might be a short between terminals 2 & 3.
CAUSE SOLUTION
Follow the Time per Coin and/or Coins per Aux instructions and verify that
it is correct for your installation.
Timed Hot (terminal 2) and 24 VAC Hot
(terminal 1) are shorted.
Remove all wire(s) from terminal 2. If the equipment is still on with the
wire(s) removed from terminal 2 of the timer, then there is a short some
where in the wiring. If the equipment shuts off after removing the wire(s)
from terminal 2, then the timer might be bad.
CAUSE SOLUTION
Time per Coin or Coins per Aux is set
for longer than is should be.
Timer will Not Stop (even after trying to cancel the time)
