The float is a direct acting float switch. Each float contains asingle-pole snap-action switch which actuates when the longitudinalaxis of the float is horizontal and deactuates when the liquidlevel falls 3-1/2" below the activation level.
The float is a chemical resistant polypropylene casing with a firmly bonded electrical cable protruding. One end of the cableis permanently connected to the enclosed snap-action switch andthe entire assembly is encapsulated to form a completelywatertight and impact resistant unit.

DUAL-CHANNEL SEAL FAILURE ALARM RELAYP/N C9-7-79
The dual seal failure module is a specialized control for monitoring seal failure. Each relay provides monitoring of two (2) submersible pump motors. Leaks are detected by sensing the conductivity of the contaminated fluid through the moisture detection probes located in the motor seal chamber and stator housing. In the event of a seal leak, the module energizes one of its SPST output relays indicating that seal maintenance or replacement is required before the motor is damaged. The sensitivity of the probe inputs is field adjustable. When the resistance between one of the probe inputs and the common connection drops below the sensitivity setting, the corresponding output relay and LED are activated.

COMBINATION SEAL FAILURE / OVERTEMPSIMPLEX ALARM RELAY
GENERAL:
The Combination Seal Failure/Overtemp Alarm Relay is a specialized control for monitoring seal failure and thermal overload of one (1) submersible pump motor. Leaks are detected by sensing the conductivity of the contaminated fluid through the moisture detection probes located in the motor seal chamber and stator housing. Over-temperature is detected by a normally-closed switches connected in series and embedded in the motor stator windings. The over-temperature function incorporates a bi-stable relay that retains its position during power failures.
OPERATION:
The states of the unit's relay outputs are determined by the series combination resistance of the leakage and temperature sensors. Under normal conditions the resistance remains between the leakage and over-temperature sensitivities, and both output relays are de-energized. If the temperature switch opens, the over-temperature relay latches on until the remote reset button is pressed. Two conditions must be met for reset to occur: 1- Power must be applied 2- The temperature switch must be closed
If the leakage sensor resistance drops below the leakage sensitivity setting, the leakage relay energizes. When the leakage condition clears, the relay resets automatically.

When the pushbutton is depressedthe indicating lamp will beilluminated to indicate: A) poweris supplied to the control, B) thecontrol is operative, and C) wiring is intact. This procedure should be performed periodically to con�rm integrity of the circuit. The integrity of the moisture probe wiring may be checked with an ohmmeter. Measured resistance between (3) & (4) should exceed 300,000 ohms.

INSTALLATION AND OPERATING INSTRUCTIONS
GENERAL:The type 2800A is a conductance-actuated control for detection of moisture in the oil chamber of a submersible pump motor. It is used as a warning device to indicate a seal leakage and to signal the need for preventative maintenance.
INSTALLATION:Mount control box vertically on wall or other solid structure and accomplish all indicated wiring. Terminals on the control are numbered and are in the same relative position as shown on the wiring diagram. Terminal pair 1-2 must be continuously energized from an A.C. supply line of electrical characteristics shown on the data plate. Contacts 8-6 and 8-7 are available for load duty, and if required, must be wired in series with the load device or devices, and that series branch circuit connected across a power source compatible with the load. Terminals 3-5 are connected to the moisture sensing probes in the motor marked W1-W2 via the cable provided with the motor.
OPERATION:The oil surrounding the probes is nonconductive and the control will be de-energized. An influx of moisture past the outer seal and into the oil reservoir will cause the relay to energize. Load contacts 8-6 and 8-7 will change from their normally open or normally closed position when the control energizes.
TEST PROCEDURE:A normally closed pushbutton and neon indicating lamp are provided as a part of the control for testing the moisture sensing relay. The motor manufacturer has provided a 330,000 ohm resistor across the probes inside the motor to complete the test. When the test pushbutton is depressed, the contacts 8-6 and 8-7 will change condition to indicate: (A) power is supplied to the control (B) the control is operative (C) the wiring is intact To test the wiring from the relay to the moisture probes in the motor, de-energize and lock out power to the moisture relay. Use a multi-meter and measure the resistance between the relay connection points 3 and 5. Resistance should be greater than 300,000 ohms showing that the wiring from the relay to the moisture probes in the motor are intact.

INSTALLATION:Mount control box vertically on wall or other solid structure and accomplish all indicated wiring. Terminals on the control are numbered and are in the same relative position as shown on the wiring diagram. Terminal pair 1-2 must be continuously energized from an A.C. supply line of electrical characteristics shown on the data plate. Contacts 8-6 and 8-7 are available for load duty, and if required, must be wired in series with the load device or devices; and that series branch circuit connected across a power source compatible with the load. Terminals 3-5 are connected to the moisture sensing probes in the motor marked W1-W2 via the cable provided with the motor.
OPERATION:The oil surrounding the probes is nonconductive, and the control and seal leakage indicator light will be de-energized. An influx of moisture past the outer seal and into the oil reservoir will cause the relay to energize, and the seal leakage light will energize to indicate a seal leakage. Load contacts 8-6 and 8-7 will also change from their normally open or normally closed position when the control energizes.
TEST PROCEDURE:A normally closed pushbutton and neon indicating lamp are provided as a part of the control for testing the moisture sensing relay. When the test pushbutton is depressed, the neon indicating lamp will be illuminated to simulate a seal leak:
(A) power is supplied to the control (B) the control is operative (C) the wiring is intact To test the wiring from the relay to the moisture probes in the motor, de-energize and lock out power to the moisture relay. Use a multi-meter and measure the resistance between the relay connection points 3 and 5. Resistance should be greater than 300,000 ohms showing that the wiring from the relay to the moisture probes in the motor are intact.
