Power Overload: There is a short circuit in one of the zone valves, in the zone valve
wiring or on the valve board in the SC24/36. Check for a shorted solenoid valve for the
zone or zones listed, and then check the valve and board wiring.
Shorted Valve: A valve connected to a sensor or flow meter is shorted. Check the
solenoid indicated.
Pipe Break: The flow rate is excessively high. This could point to a broken zone pipe or
missing sprinkler head. It could also point to a stuck valve. Check the indicated zones for
plumbing problems.
Main Break: The flow meter continued to read high when all valves are off. The main line
is broken or a valve is stuck. Check the mains and look for zones that are running without
being turned on.
Communications Error: The remote device (sensor or flow meter) is not communicating
properly with the controller. Infrequent errors are ok, but if they are regular and persistent
check the device wiring. Especially check for un-insulated wiring and loose wire nut
connections. If that is ok suspect the device.
Dead Battery: This means that the battery was dead during a power fail and the SC24/36
clock lost track of the time. You will have to replace the batteries and reset the clock.
Scheduling Overflow: The controller was not able to keep up with an aggressive watering
schedule. The list of pending zones to be watered when a program starts, the valves
operate one at a time in numeric order with each zone watering completely before
another zone begins
was dumped. Check your program scheduling for congestion. Insure that the daily
watering load does not exceed the available time.
Power Restore. Failed at TIME: A power failure occurred at the time indicated and was
restored. If the power was off for an extended period there may be zones that did not
receive water, depending on reset/recover mode.
