Probable Cause

Solution

ZSW TRIP

ZERO SPEED SWITCH

INPUT FAILED TO BE

FALSE WITHIN 1/2 OF

LOCKED ROTOR TIME,

OR WAS FALSE AT START

Discrete input 1 has been

set for zero-speed switch

sensing via setting P6L1.

The 120 Vac zero speed

switch contact input was not

present at the moment of the

start. Or, it did not go away

in one-half of the set locked

rotor or stall time P1L3. This

may be due to a motor

unable to start spinning

when it is energized.

• Make sure this function has

been intentionally enabled.

• If ZSW trip occurs at the

moment of starting, check

process wiring and contacts

to be sure a 120 Vac signal is

applied to DI 1 when the mo-

tor is stopped.

• Make sure the motor is not

stalled and actually begins to

spin.

• If a ZSW trip occurs after

one-half the locked rotor time

setting, check to be sure the

contact on the motor opens

and the 120 Vac signal goes

away before this time. Usu

ally, a zero-speed switch

should open when the motor

has reached 5% to 10% of its

normal running speed.

• Use the DI 1 test to confirm

that the relay sees the ex-

pected input voltage.

REMOTE

REMOTE TRIP

Either or both of discrete

input 1 and/or discrete input

2 are set to indicate remote

trip contact input. The input

configured in this way was

energized with 120 Vac.

Determine the source of the

remote contact operation

requesting the trip.

DIF TRIP

DIFFERENTIAL TRIP

Either or both discrete input

1 and/or discrete input 2

are set to indicate remote

trip contact input. The input

configured in this way was

energized with 120 Vac.

DaNGER:

Shut down and

lock out the motor. A differen

tial relay operation indicates

an electrical fault. Get expert

help in evaluating the condi

tion of motor and repair needs.

Do not try to restart the motor

without expert evaluation.

After or during repair or re

placement of the motor, check

the fuses in the starter and

replace blown fuses.

PH UNBAL

PHASE UNBALANCE TRIP

• Source voltage unbalance

due to remote fault or

single-phase loading.

• Single phasing of the

motor

Check for voltage balance.

Check the integrity of feeder

connections.

Check the fuses in the starter.

Do not attempt to restart

the motor until the cause of

single-phasing is found.
