Section 7: Diagnostics Circuit Breaker
Smart-Scan

Diagnostic Fault Sensing
A diagnostic fault sensor will automatically scan for the
presence of a faulty solenoid or wiring short in a valve during
each watering sequence. If a faulty station is detected, the
sprinkler timer will move to the next working station. Smart-

also detects faulty wiring for the Pump or Master Control.
Upon detection watering cycle is discontinued.
Fault Notification
• Faulty Station: “FAULT STN” and station number is
displayed. When multiple faulty stations are detected, only
the last faulty station will be displayed.
• Faulty wiring for pump/master control: “PUMP FAULT” is
displayed.
Correcting the Fault
1. First, repair the short in the wiring or replace the faulty
solenoid.
2. Test the station by operating a manual watering
sequence.
3. If the short is not detected after a few seconds, the fault
notication message will be terminated.
4. If the message continues, a short in the wiring still exists.
Internal Auto-Resetting Electronic Circuit Breaker
The sprinkler timer is equipped with an internal electronic
self-resetting circuit breaker.
Possible causes of a circuit breaker tripping:
1. If lightning strikes nearby.
2. When the power supply has an electric spike.
3. If a station has a wiring short.
Whenever one of these conditions occurs, the electronic circuit
breaker may trip, causing the station output from the sprinkler
timer to be halted momentarily. The batteries will continue
to activate the LCD. After a few moments, the sprinkler timer
will automatically retest the circuit to see if the condition has
stopped. If so, the circuit breaker will reset itself.
