The TimeMark 22-HM is a 3-phase monitor for 475-600 V AC, 50/60 Hz systems. It drops its output relay out on phase loss, phase reversal, over/under voltage and voltage unbalance and holds it out until it is reset by hand.
Trip points: undervoltage 90% of the setting ±1% (resets at 93%); overvoltage 110% of the setting ±1% (resets at 107%); unbalance 2-8% adjustable (resets 0.7% below the setting). Trip delay: undervoltage 1-30 s (adjustable). Restart: 1-500 s (adjustable). Reset: manual.
Output: 2 x SPDT, 10 A at 240 V AC resistive. Mounting: surface mount. Indicator: Normal (green) and Fault (red) LEDs. LED STATUS - Red: UNDER = on continuously; OVER, UNBAL / SINGLE PH, REVERSE PHASE = distinct blink patterns. Green: RUN = on continuously; RESTART DELAY = blinking.
