| Datasheet | Download Datasheet |
The TimeMark 407 is a triplex pump controller for a 115V AC (105-130V AC), 60 Hz supply. It runs the pumps down or up (set by N.O. or N.C. level switches), alternating them, with alarms.
Sensing: float or pressure switch contacts (12 V DC, 1 mA), or a TimeMark 408 level sensor. Set points: 5 (LOW, LEAD, LAG, LAG-LAG, HIGH). Pumps: 3, alternating or fixed lead. Controls: hand-off-auto switch per pump; lead pump selector; alarm test / silence / reset. Display: three pump run-time meters (99,999.9 h).
Output: 6 x SPST (pumps, alarm light, alarm bell, power fail), 10 A at 240 V AC resistive. Alarms: high level alarm bell and light; power-fail contact; remote pump alarms. Mounting: panel (in an enclosure). Indicators: pump running, remote alarm, level switch, alarm and power LEDs. Power: 10 W max. It operates from -29 to +60 °C.
