Overwatering timers are in the second last tower box, and they shut the system down if it fails to move after a pre-selected time.
Eagle overwatering timers
Eagle overwatering timers are surface mounted and have a heavy duty terminal block, with nine screw terminals ready to accept 16 gauge wire. A standard pilot light illuminates during timing period.
The case of the timer is made of injection molded Lexan polycarbonate. This ensures high impact strength as well as high dimensional stability. Completely enclosed construction with front facing dial and knob.
There are 2 different time ranges available (0-60 and 0-5 minutes) in 120VAC, 50/60Hz.
These electronic timers are micro processor driven, and provide an accurate adjustable time delay between the actuation of the control circuit and the operation of the load switches. They have an operating temperature from –20° to 60°C.
