The seal failure module is a specialized control for monitoring the shaft seal of a submersible pump motor. A leak is detected by sensing the position of a resistive float switch installed in the seal cavity. When the resistance drops below the sensitivity rating, the output relay energizes and the LED illuminates. When the fault condition clears, the output relay resets automatically.

The dual seal failure module is a specialized control for monitoring the shaft seals of two submersible pump motors. Leaks are detected by sensing the conductivity of the contaminating fluid through probes installed in the seal cavity. When a seal begins to leak, the seal failure module energizes one of its SPST output relays indicating that the seal needs to be replaced 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.

The nonvolatile latching temperature switch relay monitors a normally-closed-low temperature switch. It incorporates a bistable relay that retains its state during power failures. LEDs indicate the status of the relay, and connections for an external reset button are provided for manual control. The reset inputs of multiple units may be connected to a single push button as long as proper polarity is observed when making the connections. Under normal conditions the temperature switch is closed and the relay is de-energized. When the temperature switch opens, the relay energizes and latches on until the temperature switch recloses and the reset button is pressed. The unit will function properly with zero to 2 k ohm of resistance in series with the temperature switch.

The dual function simplex alarm/relay is a specialized control for monitoring the shaft seal and stator temperature of a submersible pump motor. Seal leakage is detected by either a resistive float switch or a pair of conductive probes installed in the seal cavity. Over-temperature is detected by a normally-closed-low temperature switch mounted on the stator. The over-temperature function incorporates a bistable relay that retains its position during power failures.

The PRT-100 is a handheld tester that takes the guesswork out of connecting a three-phrase motor. The direction of rotation of a motor depends on phase sequence of the power line connections. If the sequence is reversed, the motor will run in the wrong direction, possibly damaging the equipment connected to the motor. The PRT-100 identifies the leads of a three-phase motor and detects the sequence of a three-phase power line. Once the motor and line leads are properly identified, the motor can be wired so that it turns in the desired direction on the first try. The unit also detects phase loss and no voltage conditions.

BFA Series


With nominal 3 phase line voltage applied, a flashing green NORMAL LED gives positive indication of a good fuse and integrity of the wire connection to each side of the fuse.

A flashing red FAULT LED gives positive indication of an unconnected or open fuse, or a BFA wiring fault that needs corrected such as a lost connection to either side of the fuse or mismatched line and load wires.

When phase loss occurs, both FAULT and NORMAL LEDS will extinguish The BFA will continue to indicate the status of the fuse during a phase loss if a regenerated voltage is produced on the open phase from a rotating motor.

GFD Series


The GFD-XXX is intended for the use on ungrounded systems to detect and indicate the phase of the first ground fault condition. This enables corrective action to avoid the potential hazards resulting from a second ground fault. With nominal 3 phase line voltage applied, a flashing NORMAL green LED gives indication of a non-fault condition and integrity of the wire connection to the corresponding phase.

A Flashing red LED gives positive FAULT indication of either a phase-to-ground fault, or a lost connection to the corresponding phase.

UPA-100 Series

UL Approved
CSA Approved

With the green (GND) wire connected to earth ground, the eight detector UPA-100 visually alerts to the presence of dangerous AC or DC (Stored Energy) potentials occurring between any combination of the four monitored input lines (L1, L2, L3, GND). Two LED indicators are assigned to each input line and are designated "+" and "-". For each input line carrying an AC potential (bipolar), both the "+" and "-" LEDs will be active. A DC or Stored Energy potential will illuminate the "+" LED for the positive line and the "-" LED for the negative line.


Following the application of lockout or tagout devices to energy isolating devices, all potentially hazardous stored or residual energy shall be relieved, disconnected, restrained, and otherwise rendered safe.
If there is a possibility of reaccumulation of stored energy to a hazardous level, verification of isolation shall be continued until the servicing or maintenance is completed, or until the possibility of such accumulation no longer exists.
"Verification of Isolation." Prior to starting work on machines or equipment that have been locked out or tagged out, the authorized employee shall verify that isolation and de-enegerization of the machine or equipment have been accomplished.

When the voltage to your equipment is lost due to tripped breakers, blown fuses, or loss of utility power. Simply remove the existing cord set plug from the outlet, plug into the properly sized MotoReset device, and plug the assembly back into the outlet. The unsupervised unintentional automatic restart of equipment when breakers are reset or when utility power is restored after an outage. Restoration of utilities with equipment control switches left in the “ON” position will not restart with the MotoReset in place. The need for additional, potentially hazardous, manual reset pushbuttons. The MotoReset turns the equipment existing ON/OFF switch into a manual reset switch. The operator does not have to leave the immediate vicinity, nor the normal operating position of protected equipment, to safely reset after an outage. Simply switch the equipment “OFF” to reset to normal operation.

CCT Series


The CCT Series, Crank Cycle Timer, provides a sequential Crank/Reset signal for starting commercial and industrial portable, standby, and emergency power generators. When the supply voltage is applied to the input terminals, Load #1 energizes and the Crank Time (t1) begins. Upon completion, Load #1 de-energizes and the rest time (t2) begins. Upon completion, Load #1 energizes. This Crank/Rest action continues for a preselected number of cycles, where upon completion, Load #1 locks in a de-energized state and Load #2 energizes. Reset is accomplished by interrupting the supply voltage.

PLEASE NOTE: This timer has been obsoleted by ATC/Diversified. Please contact us at 800-479-4783 regarding a low-cost PLC replacement offering.
