When the controller is activated by either “Auto” programming or a “Manual” Input, the power plus an
encoded signal is supplied to the four eld Outputs.
The Receiver operates as an electronically controlled switch. When the receiver recognizes the en-
coded signal that matches its programmed data, it then allows or “switches” power to the solenoid at the
valve. Each receiver has a Red LED that will light when the receiver is “switched” or activated. When
testing or troubleshooting, this LED is a convenient indicator of the Receiver Status. Lit condition indi-
cates that the signal and power are present and the Power is being sent to the solenoid.
An unlit condition indicates the receiver is not activated. This is an indication that the power and/or
signal is not present.
The controller, through its current monitoring ability, can display two fault conditions: One being “Short
Line” the second being “Valve Short.” These faults are triggered when current draw has exceeded a
present level.
If this current draw is sensed at a programs initial start a line short will be displayed.
If the current draw is sensed during a valve run time then short valve with a valve number will be dis-
played.
Short line will retry after 20 minutes. Turning the dial out of “Run” and back will clear the display. The
controller will then try to continue any scheduled program. If the short has not been corrected the con-
troller will go back into “Line Short”.
“Short Valve” will stay displayed during the valve run time. The controller will monitor the program status
and operation will resume when the next valve is activated. If the problem has not been corrected by
the time the controller is scheduled to Run again the “Short Valve” will repeat.
