The TimeMark 422 is a submersible pump controller for a 100-130V AC or 200-250V AC, 50/60 Hz supply. It trips on motor overload or underload, sensed as true motor power (V x A x PF).
Sensing: motor voltage and current (direct to 3.5 A; TimeMark 276A / 276B CTs; 276C for 3-phase). Input: current 0-5 A (CT secondary). Delay: off or 0.3...180 s (trip delay). Reset delay: off or 0.1...4 h (restart delay). Reset: power cycle, reset button or restart timer (DIP selected).
Output: 1C SPDT, 10 A at 240 V AC resistive. Signal output: 4-20 mA proportional to motor power (chart recorder). Mounting: panel (in an enclosure). Indicators: red LED: tripped (overload / underload); yellow LED: restart timing. Power: 0.5 VA max. It operates from -29 to +55 °C. Approvals: UL Listed (U.S. and Canada), CSA Certified.
