DESCRIPTION

The APMR protects three phase equipment, mostly motors, from destructive

line conditions. Specifically it detects Phase Reversal, Phase Loss, Phase

Unbalance and Low Voltage. All of these conditions, except for Phase Reversal,

produce excessive heating of motor windings, causing immediate or cumulative

damage to the motor. Phase Reversal will cause a motor to operate in the reverse

intended direction, possibly damaging machinery.

There are three models available; 230 VAC, 380 VAC, and 480 VAC. The

230 VAC model is used with 208, 220, 230, and 240 VAC rated equipment. The

380 VAC model is used with 380 and 415 VAC (European) equipment. The 480

VAC model is used with 440, 460, and 480 VAC rated equipment. The

electrical connection is three wire Delta or WYE configurations (no neutral

connection required).

The output is SPDT relay and LED. The relay is typically connected in series

with a motor contactor coil to inhibit motor start or to disconnect the motor in

the presence of a fault condition. The relay automatically resets when the fault

clears. The relay is typically used in a latching configuration so the motor has

to be restarted after the fault is cleared. The LED illuminates green when all

conditions are normal - no fault. When the LED is green, the relay is energized.

When a fault occurs, the LED turns red and the relay is de-energized. If phase

loss occurs on L1 or L3 the LED turns-off and the relay is de-energized.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

manual or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

FUNCTION DESCRIPTIONS 5. In extremely high EMI environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core several times or use multiple cores on each cable for additional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure.

SETUP 5. Set the Under Voltage Delay to the desired value. This is the maximum time period that an under voltage condition can exist before de-energizing the internal relay. The exact value of the delay depends on the type of equipment being protected and the quality of the available three phase power. A setting too low, will cause unnecessary interruptions due to momentary dips in the line voltage.

APPLICATION A waste water treatment plant had just completed a costly repair program, reconditioning several motors used in their pumping process. The necessity to rebuild was the direct result of unbalanced and low voltage supply lines causing excessive heating to the motor windings. The continual operation below acceptable levels of power supply lead to the failure of the motor windings. The APMR (3 phase fault detector) was included in the repair program.
