Time Mark 662

This is Pump Up Control is designed to monitor and maintain liquid levels. A user-provided 4-20mA current loop represents the liquid level, and output connections are provided for pump control. The HIGH ADJUSTsetpoint, and the LOW ADJUST setpoint, are field adjustable. If the input falls below the low setpoint, the PUMP UP relay energizes, and remains that way until the input rises above the high setpoint. The high setpoint must always be set above the low setpoint. Top-mounted LEDs show system status. The PUMP UP LED turns ON when the input falls to 10 percent below the low setpoint, and resets when the input rises above this level. An INPUT LOOP ERROR LED turns ON if the input is outside the 4-20mA range. A Time Mark Model 650 Loop Power Supply (or equivalent) is required to provide the 24 VDC operating voltage. A Time Mark Model 672-15 Pressure Transducer (or equivalent) is required to provide the input signal.
