FAULT DESCRIPTION
OUTPUT SHORT CIRCUIT: A load placed on any output that results in a current draw exceeding the skip current
setting will result in a fault within 3 AC cycles after the output is turned on. The output will be skipped until the
next watering program attempts to use it. If the MV/P output is shorted, all zones using it will effectively be
skipped. The fault indication can be manually cleared or will be automatically cleared if the short condition goes
away; and the output turns on successfully. See Section 6.2.1 Outputs for instructions on reading actual current.
OUTPUT OPEN CIRCUIT: If a used zone exhibits a load that results in a current draw less than 30 mA
during a scan test, a fault is declared, but operation continues normally. The fault indication can be
manually cleared or will be automatically cleared if a load exceeding 30 mA is placed on the output,
and the output turns on successfully. See Section 6.2.1 Outputs for instructions on reading actual current.
COMMUNICATIONS FAILURE: If the SmartLine
®
controller is in Auto Adjust mode, and the daily
high/low temperature has not been received by midnight, the communication fault is set. Also, if the
battery in the SLW weather station is dead, the communication fault is set. If 5 days pass without
communication, the controller will revert to the Standard mode Zone Run Times. The fault indication
can be manually cleared or will clear automatically once communication is received.
If the SmartLine
®
controller receives communication from the SLW weather station that indicates the
remote battery is low, the fault is set. The fault indication can be manually cleared, or will clear
automatically if the SLW weather station sends another message that indicates a good battery. The
fault will also clear if no communication is received for a full day (i.e. communication failure). See
Section 7.2 Replacing SLW Series Weather Station 9V Battery.
INSUFFICIENT WATERING OPPORTUNITY: If the SmartLine
®
controller is in Auto Adjust mode, and a
daily deficit is calculated that results in a zone watering deficit in excess of the 1.5” maximum, the
deficit is capped to the maximum and the fault is set. The calculation can also occur as part of the
deficit gap recovery process, which happens when the SmartLine
®
controller loses power for over a
day and then recovers. The fault is cleared manually.
