INVERSE OPERATION FROM B/W ELECTRODES

GROUND CONNECTIONS

In all installations, a good external ground connection and a dependable return circuit to the liquid are required. In most

instances, grounding to a metal pipe leading to the tank is suitable, but electrical conduit should not be used for this purpose.

If a good ground connection to the liquid is not available, an additional ground electrode is required. When used, the ground

electrode should extend slightly below the longest operating electrode. In addition, it is also desirable to ground the relay

chassis directly to the ground terminal or through a relay mounting screw.

SERIES 5200 RELAY OPERATION

Positive fail-safe control can be obtained simply by connecting the proper R1 resistor to the terminal block for direct or inverse

operation as shown in the diagrams.

DIRECT OPERATION

In direct operation, the load relay is energized when liquid contacts the upper electrode, or Unifloat® reed switch, and

electrode current is flowing.

INVERSE OPERATION

In inverse operation, the load relay is energized when the liquid falls below the lower electrode, or Unifloat® reed switch, and

current ceases to flow.

Series 5200 Solid-Sate relays are designed for controlling a wide variety of high and low resistance liquids, moist bulk

materials, and general purpose use in applications requiring a low voltage control circuit.

Supplied as compact package units, they combine performance-proven solid-state printed circuitry with an electromechanical

load relay that features isolated double pole / double throw contacts for energizing pump motors, valves and other operating

equipment.

Equipped with silicon controlled rectifiers, the 5200 Series Relay assures years of service without change in operating

characteristics. The Relay will operate with less than a 10% difference between pull-in and drop-out resistance and can be

mounted in any position. Units are field selectable for either DIRECT or INVERSE operation.

Series 5200 Solid-State Relays are available in two sensitivity ranges, LOW and HIGH.

LOW SENSITIVITY:

This relay is designed for the control or detection of electrically conductive liquids with low to medium specific resistance.

Typical liquids are potable and waste water, most acids, plating solutions, fruit juices, soup, beer, milk, and soft drinks. With a

low voltage AC electrode potential, this relay operates with no shock or sparking hazard. It is ideal for food, drug, dairy, and

chemical processing applications.

HIGH SENSITIVITY:

This relay is recommended for the control or detection of electrically conductive liquids with medium to high specific

resistance. Typical liquids are distilled and de-ionized water steam condensate, alcohol, glycols and anhydrous ammonia. It

is also suitable for detecting or controlling ore, foundry sand and other bulk materials with low moisture content. With a low

voltage DC electrode potential and no existing shock hazard in the electrode circuit, this relay is an excellent choice for use in

applications where the relay must be located many thousands of feet away from the electrodes.

SENSITIVITY SELECTION B / W level control systems use the liquid as an electrical conductor to complete the Series 5200 relay sensing circuit, and it is necessary that the relay have an operating sensitivity greater than the resistance of the liquid to be controlled. The sensitivity of both models of the Series 5200 relay is determined by the valued of the replaceable R1 resistor used.
