Eagle Signal percentage timers are continuous ON-OFF control devices commonly used in irrigation systems.

Percentage timers operate by a synchronous motor-driven cam that closes a snap action switch for a percentage of the total time cycle. Users can adjust settings while the timer is in operation. Adjust the setting of the pointer to change the relationship of the switch transfer point at zero and desired interval. As the progress pointer passes zero, the load switch transfers. Percentage timers continue to operate as a repeat cycle timer as long as power is supplied to the motor.

Commonly Asked Questions About Percentage Timers

What is a percentage timer?

Percentage timers are repeat cycle timers that output continuous on-off cycles based on the percent of time selected by the user. Percentage timers are field-adjustable and provide flexibility for applications that require repetitive cycle times.

How do percentage timers work?

Percentage timers continuously switch equipment on and off based on a motor-driven cam that closes a switch for a percentage of the total cycle time. The operator selects the desired interval. As long as the motor is receiving power, the percentage timer will continue operation.
