Electrical Hook-ups
3. Connect the green ground wire directly to the terminal
labeled “GND.”
In areas where lightning is prevalent or the condition of the third wire
ground is questionable, a ground rod must be installed. Connect the
grounding rod to the controller’s case ground using a #10 gauge or
heavier stranded copper wire.
The distance from the controller’s case to the earth ground should
be minimized.

HOOKING UP THE VALVES
A maximum of 20 VA (0.8 amps) may be output on each station.
A maximum of 36 VA ( 1.5 amps) may be programmed to operate
simultaneously (including master valve).
1. Strip the solenoid wires approximately l/2 inch (do not bend
exposed end).
2. Following the wiring diagram in figure 1, insert straight bare wire
between the plates of the “sure grip” terminal. Connect one solenoid
wire to the station terminal and the other to common. Tighten screws
firmly.
C A U T I O N : Use a separate (dedicated) valve common wire for
each controller. DO NOT daisy-chain controllers
together using the same common wire.
3. Before turning on the power, recheck all leads connected to the
terminal block for shorts.
TESTING THE VALVE HOOK-UPS
C A U T I O N : NEVER short wires in order to identify a station or
to verify power from 24-volt side of transformer.
This will result in damage to controller and/or
transformer.
1. Make sure the valve common wire and all station wires are connected.
2. Turn on power to the controller.
3. Turn dial to Valve Test position.
4. Press Advance A or Advance
to change the test time from 1 min.
to 9 min. If time is not changed, 2 min. will be assumed.
5. Press the On A key.
Each station in sequence will turn on for the number of minutes you
selected. A short circuit test will occur during the valve test. If a short
circuit condition exists on any station, the controller will display
“FUSE” alternately with the station number or zero (0) for the master
valve. “FUSE” indicates a short on that station.
NOTE:
Any operating program cycles will be paused during a
valve test cycle.
