Automatic Circuit Protection; Adding A Zone Module - Toro 53765 - Outdoor Ecxtra Sprinkler Timer User Manual

Automatic Circuit Protection

The ECXTRA features built-in circuit protection to help
prevent damage to the timer caused by excessive current
draw on the zone and/or pump/master valve circuits.
The instant an overload condition is detected, the affect-
ed zone is turned OFF and the
next zone in the watering
sequence is turned ON. The
word "Fuse" and the bypassed
zone number(s) will be begin
flashing. If the condition occurs on the pump/master valve
circuit, the timer will alternately display MV and FUSE
and discontinue the program
operation.
To clear the warning display,
press the –/ button. The
OFF
timer will resume normal operation
as scheduled and will attempt to
run all zones as programmed.
IMPORTANT: Clearing the display does not correct
the problem. The timer will continue to bypass the
affected zones or discontinue operation until the
overload condition is eliminated. Before continuing
to operate the timer, take corrective action to resolve
the cause of the problem. Generally this condition is
caused by a faulty valve solenoid or pump start relay.
