6 Ec Controller
CONTROLLER BASICS
Programming Under Battery Power
If you wish, you can program the controller under battery
power. This feature can be useful if the controller is installed
in an area that is not readily accessible. This feature also
allows you to enter program information before installing the
controller at a job site.
To program the Ec controller under battery power, you must first
install the battery.
NOTE : To save battery power, the Ec goes into
“Sleep” mode after 40 seconds of inactivity on
the programming dial or buttons. Press any button
once to reactivate the controller.
Installing the Battery
DIAGRAM 2
The battery back-up feature retains time, date, and
programming information during power outages. The battery
also lets you program the controller under battery power
before it is connected to an AC power supply.
For best results, use a long-life, 9-Volt alkaline battery. A new
battery will normally provide power for up to one year. Replace
the battery yearly to ensure an uninterrupted power supply.
NOTE : Make sure the controller is connected to an
AC power supply when replacing the battery, or you
will lose all programming information including
date and time.
To install the battery:
1. Remove the controller’s lower access cover to expose the
battery compartment.
2. Snap the two-wire battery clip onto the terminals of the
new battery. If you are replacing an old battery, dispose of
the old battery properly.
3. Insert the new battery snugly into the battery
compartment.
4. Replace the lower access cover.
Diagnostic Circuit Breaker
DIAGRAM 3
If the Ec controller detects an electrical short circuit on one of
the sprinkler system’s station wires or valve solenoids, the
controller automatically shuts off the station with the fault. After
30 to 40 seconds, while it checks again to confirm the fault,
the controller advances to the next working station in the
program.
