663
The 600 Series Pump Down Control, SKU 663, offers reliable liquid level management for industrial applications. Its automatic reset function ensures continuous operation without manual intervention, minimizing downtime. Users benefit from two adjustable trip points, allowing precise control over pump cycles based on specific process requirements. The device accepts a standard 4-20mA input signal, integrating seamlessly into existing industrial control systems. With a robust contact rating of SPDT 10 amps at 240VAC and an expected mechanical relay life of 10 million operations, this control provides long-term, dependable performance. It operates effectively within a -13° to +122° F temperature range and tolerates 0-97% humidity without condensation, ensuring durability in varied environments. This unit delivers consistent, dependable pump control, backed by a 5-year unconditional warranty.
The Model 663 Pump Down Control, part of the 600 series line of
instrumentation controls, is designed to monitor and maintain liquid
levels. A user-provided 4-20mA current loop represents the liquid level.
The HIGH ADJUST setpoint, and the LOW ADJUST setpoint, are field
adjustable. If the input rises above the high setpoint, the PUMP DOWN
relay energizes, and remains that way until the input falls below the
low set point. Top-mounted LEDs on the Model 663 show system status. The
PUMP DOWN LED turns ON when the input is above the high setpoint, and
goes OFF when the input is below the low setpoint. The HIGH ALARM
condition indicator turns ON if the input rises to 10% above the high
setpoint. The HIGH ALARM condition then resets when the input is again
less than 10% above the high setpoint. For proper operation, the high
setpoint must always be set above the low setpoint. 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. Also, a Time Mark Model 672-15 Pressure Transducer
(or equivalent) is required to provide the input signal.
