The HQ4 series 48 percentage timer is a panel mounted unit with exposed dial. The heavy duty front dial plate has 4 mounting studs for simple and secure mounting to panels up to 1/4 inch thick. The load switches and motor are enclosed for environmental protection. Connections to load switches and timing motor are made to screw terminals on the rear of the unit.

Operation:

A synchronous motor driven cam closes a snap action switch for a selected percentage of the total time cycle of the unit. Percentage settings are made with a knob and dial on the front of the unit. Settings may be made or changed with the timer operating. With a dial setting between 5% and 100%, terminals 2 and 3 are closed relative to the setting. At 100% setting, terminals 2 and 3 are closed continuously. At 0% setting, terminals 2 and 3 are open continuously.
