Component Operation and Checks
Timer
The timer controls how long the pump will run after the "start" push button is pushed in.
Two different timers have been used. They function the same but the settings differ. The
timer settings should be as follows:
ISSC Timer IDEC timer
MODE SF D
RANGE HRS 10H
FACE NUMBERS 0 through 10 0 through 1
DIAL SETTING 4 .4
When the "start" push button is pushed, the timer is activated and sends X1 power to
terminal A1 on the motor starter/overload.
The timer can be checked as follows:
1. Make sure the timer is set as indicated above.
2. If the red "power" light is on, go to step 5. If the red "power" light is not on, go to
step 3.
3. Check voltage across terminal 10 on the timer socket and X1 on the transformer. It
should be 20-28v. If voltage is 20-28v, go to step 4. If there is no voltage, check
the breaker, fuses, transformer and wiring.
4. Check voltage across terminal 2 on the timer socket and X2 on the transformer and
terminal 11 on the timer socket and X2 on the transformer. It should be 20-28v. If
voltage is 20-28v, go to step 5. If there is no voltage, check the breaker, fuses,
transformer, liquid level control, stop switch and wiring. Make the necessary
repair.
5. TURN POWER OFF AT BREAKER PANEL. Remove the timer from the socket.
6. Make sure there is continuity between terminal 6 on the socket and terminal 4 on
the "start" push button. If not, trace the wire and make the necessary repair.
7. Push and hold the "start" push button in and check for continuity between terminals
3 and 4 on switch. If there is no continuity, replace the "start" switch.
8. Reinstall the timer and turn power on. Wait 10 seconds for the liquid level control
to activate. The red "power" light should come on.
9. Check voltage across terminal 3 on the "start" push button and X2 on the
transformer. It should be 20-28v. If voltage is 24, go to step 11. If there is no
voltage, trace the wire to the "stop" switch and make the necessary repair.
10. Push and release the "start" push button. Check voltage across terminal 9 on the
timer socket and X2 on the transformer. It should be 20-28v. The green "OP" light
should flash on the ISSC timer. The red "OUT" light should illuminate on the
IDEC timer. If there is no voltage, the time is defective.
