Time Mark 15 Data Sheet

MODEL 15

TIME MARK is a division of

Reverse Phase

Correction Relay

 Senses and automatically corrects

for damaging phase reversal

 Low power consumption
 Unconditional 5-Year Warranty

DESCRIPTION

Under normal power conditions, incoming A B C voltage
is passed straight through the device to the A B C
output terminals (4 amps @ 480 VAC resistive
maximum). If the unit detects an incoming reverse
phase condition (C B A), it will light the reverse phase
LED and internally switch 2 of the phases and pass the

corrected phasing out to output terminals A B C.

If your load is higher than 4 amps @ 480VAC resistive,
the Model 15 provides an auxiliary output relay to put in
the control circuit of a remote reversing contactor. If
phasing is correct, the relay will remain in the static
condition (N.C contact will remain closed and N.O. will
remain open). If the Model 15 detects a reverse phase
input, the auxiliary output relay will energize and the
relay contacts will switch (N.C contact will open and
N.O. will close). Reversing the phases is done through

the wiring of the reversing contactor.

INSTALLATION

1. Mount the Model 15 in the desired location.

2. Connect the 3 - phase power to the input
terminals marked A, B and C.

3. When using a reversing contactor, connect the
control circuit to the Aux Output terminals
and then to the reversing contactor.
(Refer to the Typical Motor

Application wiring diagram
for additional information).
