OPERATING PRINCIPLE:
Ulanet thermal timers comprise an assembly having one stationary adjustable contact and one movable contact attached to the end of a bimetal strip. A heater coil winding is insulated from the bimetal by a wrapping of high dielectric heat resisting tape. Upon energizing the heater coil the bimetal bends and either closes or opens a set of contacts according to adjustment screw settings. After heater is deenergized the bimetal cools and returns to its original position.
Normally open timers close contacts after energization. To increase timing turn adjustment screw so that contact gap is increased
Normally closed timers open contacts after heater coil is energized. To increase timing turn adjustment screw in the direction that increases contact pressure.
Is a heavy duty thermal timer housed in a metal case.
Mounting holes for #10 screws spaced at 2-3/4" centers. Terminals
are provided for heater and 4" leads for the contact circuit.
