DESCRIPTION

The Model 662 Pump Up 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, 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 on the Model 662 show system status.
The PUMP UP LED turns ON when the input falls to 10%
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 24VDC operating voltage. A Time
Mark Model 672-15 Pressure Transducer (or equivalent) is
required to provide the input signal.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

THE MODEL 662 PUMP UP CONTROL IS NOT TO BE USED WITH INPUT VOLTAGES OTHER THAN 24VDC.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

INSTALLATION

Connect 24VDC power to pins 1 and 3 on the 11-pin socket.

Connect the 4-20mA input signal to pins 4 and 5, and the other
pins to the appropriate units in your loop system, following the
base diagram shown on the Model 662 unit (and on this data
sheet). When using separate supplies for 4-20mA and 24VDC
you must connect pins 3 and 5 together. Pay careful attention to

polarity.

NOTE: When installing the Model 662 in areas of high humidity or
contamination, it is recommended that the base area and all exposed
metal parts of the socket be coated liberally with a good quality
silicone grease, such as Dow Corning DC-4 or DC-4X. Insert the unit
into the socket and wipe off excess grease around the base. This will
prevent the entrance of moisture and other contaminates into the
base and socket areas.

ADJUSTMENT PROCEDURE

The Model 662 Pump Up Control relays are normally de­energized. If the input falls below the LOW TRIP POINT, the
pump relay energizes, and the PUMP UP LED is lit.

If the input falls below the LOW ALARM trip point (10% below the
LOW TRIP POINT), the low alarm relay energizes and the LOW
ALARM LED is lit.

If the input returns to a level above the LOW ALARM trip point,
the low alarm relay de-energizes, but the pump relay remains
energized until the input rises above the HIGH TRIP POINT (see
Operation Diagram). The PUMP UP and LOW ALARM LEDs
may be used to indicate the tripped condition in the following
adjustments.

Before Adjustment: For each application, you must select the
setpoints for the LOW TRIP (the level at which you want the

pump to start pumping) and the HIGH TRIP (the level above
which you do not want the pump to operate). These two

setpoints, in ma, are used to adjust the Model 662. The LOW
ALARM trip is an internal function of the device which is set
approximately 10% below the LOW TRIP.

To Begin: Turn both the LOW ADJUST and the HIGH ADJUST
fully counter-clockwise, to their lowest settings. Both PUMP UP
and LOW ALARM LEDs should be out.

To adjust the LOW TRIP: With the Model 680 4-20mA Simulator
(or other adjustable, known signal source), apply the current
level .

for the LOW TRIP. Turn the HIGH ADJUST pot fully clockwise.
Then, slowly turn the LOW ADJUST pot clockwise, until the
PUMP UP LED illuminates

PIN DRAWING

To Adjust the HIGH TRIP: With the Model 680 4-20mA
Simulator (or other adjustable, known signal source), apply the
current level for the HIGH TRIP. Turn the HIGH ADJUST pot
slowly, counter-clockwise until the PUMP UP LED goes out.

Check Setpoints: With the Model 680 4-20mA Simulator (or
other adjustable, known signal source), check the high and
low trip points and the LOW ALARM setpoint by applying
current levels above and below the chosen setpoints, noting
the current values shown when the LEDs come on.

Input Loop Error: Check the INPUT LOOP ERROR function
by applying current levels above and below the 4-20mA
range. The INPUT LOOP ERROR LED should illuminate
when current is above 20mA or below 4mA.

TROUBLESHOOTING

Should the Model 662 Pump Up Control fail to operate, check
all connections. Verify that the proper input source voltage is
present, and check all fuses. Should problems persist,
contact the factory at 800-862-2875 for assistance.
