Series EP1217 and EP1227 Solid State Motor Timers

Tecmark Series EP1217 and EP1227 family of solid state motor timers are command systems which employ a conformal coated, open panel circuit board assembly. The controls include a digital timer circuit and integral air switch mounted to a double-sided fiberglass printed circuit board. Individual models are configured for installation in various motor end bell assemblies or for mounting in separate electrical enclosures. This family of timers offer 10, 20, and 30 minute time delay periods as standard, with other time delay periods available as options. All models feature reset capability for additional time. Additionally, models are available for use with the Tecmark® EP1226 solid state, non-contact liquid level sensor.


Upon actuation of the PCB mounted air switch, the timer is started and the load relay is energized, applying line voltage to the output terminal. The load relay will de-energize when the time delay period expires, or if a second air switch actuation occurs during the time delay period. In both cases, the load relay is interrupted and the timer is reset.


Models configured to work in conjunction with Tecmark's EP1226 level sensor module have a three-pin header to facilitate easy electrical connection. The level sensor will inhibit actuation of the timer's load relay until a preselected fluid level has been attained. If fluid level drops below the sensor actuation point during normal operation of the timer, the load relay will immediately de-energize to prohibit potential equipment or liquid spray damage. The timer will remain de-energized until the proper fluid level is reacquired and the PCB mounted air switch is actuated again.
