Error Detection
The ESP-Me controller has built-in error detection that
can automatically generate an ALARM caused by an
essential programming error or if an electrical short
condition is detected.
The ALARM LED light on the ESP-Me controller front
panel will light up to indicate an alarm condition:

is corrected.

When an electrical error is detected, irrigation for the
affected station is cancelled and watering advances to
the next operable station in the program.
The controller will attempt to water the affected sta-
tion again at the next scheduled watering. Completion
of a successful watering will clear the error condition
associated with that station.
Clearing Electrical Error Alarms
Turn the dial to the
AUTO RUN
posi-
tion to view the error message on the
display. To clear the ALARM, press the
right arrow
button.
