Chemical Feed Timers

Chemical feed timers are designed to automate the addition of various chemicals by activating a relay output.

Multiple timers can be supplied depending upon the model number and each timer will include a relay output.

All timers can be programmed to be one of the following types.

1. Pulse Time - Accepts pulses from a make-up water meter (supplied separately). It can accumulate

1-9999 gallons before activating the timer to run.

2. Feed with Bleed - Activates the relay output simultaneously with the bleed and limits the amount

of time the relay output will be on during the bleed cycle.

3. Feed after Bleed$FWLYDWHVWKHUHOD\RXWSXWEDVHGRQDXVHUGH¿QHGSHUFHQWDJHRIWLPHEDVHG

5. 28 Day - The timer is based on a 28 day cycle with four independent programmable feed cycles

with prebleed and bleed lockout settings.

VAC at 47 to 63 Hz on the incoming wiring. Each output relay is individually protected with a replaceable fuse.

Relay outputs will equal incoming line voltage.

WARNINGS:

1. The controller should be connected to its own isolated circuit breaker, and for best

results, the ground should be a true earth ground, not shared. Wiring must be done

according to all applicable local codes.

2. Power (line voltage) must be disconnected while making any connections. If power is

supplied to the unit, line voltage will be present on the relay cards located in the
