8950 TIMER CONTROL MODULE INSTALLATION

1. Install the module on the wall.

A. If possible, do not install above the wash vat.
B. 10' of 1/4" OD rigid tubing has been provided for the pressure switch line.

1. Route the 1/4" OD rigid tubing between the flexible tubing on the pressure switch and the rubber bushing, on the input plate. Tubing should be sloped for self-draining so condensation does not accumulate.
2. Wiring the control box: All wiring on installation should be done according to National Electrical Code and Local Regulations. Be absolutely certain this unit is grounded to an approved ground. Ground both modules.

A. POWER INPUT: 115 VAC 60 HZ. SINGLE PHASE. Input terminal L1, N for Neutral and Ground.

B. The terminal blocks marked 1 through 6 are to be interconnected 1 to 1, 2 to 2, 3 to 3, 4 to 4, 5 to 5 and 6 to 6 between the control and dispenser modules.

C. REMOTE WATER VALVES: The HOT valve is wired to 3 and the COLD valve is wired to 6 on the terminal block marked 1 through 6. The water valve neutrals are wired to the main neutral buss on the 16 position terminal block.

The REMOTE WATER VALVE coils must not have a rating higher than 2 amp. Do not fill the wash tank or vat faster than the time it takes to put the required amount of chemical in.

This unit has a door interlock. Pull the button out to operate the unit with the door open. Door screws must be tightened far enough to energize this interlock.

ADJUSTMENTS

1. FAILSAFE TIMER--This timer is adjustable up to 100 minutes. It monitors the time it takes to complete the wash cycle through the second rinse. It should be adjusted to a time greater than the time it takes to complete the entire wash cycle. Keep in mind, water pressure changes, cow drinking, etc. If this timer times out, the failsafe light will come on and the control unit stops.
2. FIRST RINSE AND WASH--See 9750 sequence control rinse and wash notes for ADJUSTMENT procedure.
3. 24-HOUR CLOCK--The 24-hour clock will only advance the main timer when the dial is in the "OFF" position, between the second rinse and sanitize.

A. Pull two (orange) trippers "ON" one hour before milking.

B. Turn (orange) tripper dial to time pointer to set time of day.

ALL WIRING ON INSTALATION SHOULD BE DONE ACCORDING TO NATIONAL ELECTRICAL CODE AND LOCAL REGULATIONS.
ALL OUTPUT LOADS GREATE THAN 1 AMP. REQUIRE A 115 VAC CONTACTOR INTERFACE.
115 VAC 60 HZ SINGLE PHASE 3 WRITE. BE ABSOLUTELY CERTAIN THIS UNIT IS GROUNDED TO AN APPROVED GROUND.
3 FOR WARM SANITIZE: CONNECT THE BLACK/ PURPLE WIDTH TO A CAPPED BLACK WRITE. NEXT TO THE BLACK WRITE (labelled HOT) ON THE WHITE TIME8 CONNECTOR.
FOR WARM SANITIZE: CONNECT THE BLACK / PURPLE WRITE TO A CAPPED BLACK WRITE. NEXT TO THE BLACK WRITE (labelled HOT) ON THE WHITE TIMER CONNECTOR.
FOR WARM ACID: CONNECT THE BLACK / ORANGE WRITE TO A CAPPED BLACK WRITE. NEXT TO A BLACK WRITE (labelled HOT) ON THE WHITE TIMER CONNECTOR.
FOR POWDER DETERGENT: MOVE THE BLACK WRITE (labelled HOT) FROM THE BLACK WRITE TERMINAL TO THE BLACK / SLIVER WRITE TERMINAL ON THE WHITE TIMER CONNECTOR.
