IMPORTANT: READ THIS FIRST IF REPLA CING A PMP SERIES PRODUCT WITH DATE CODE OF 1414 OR EARLIER

Macromatic made several product desig n enhancements on all PMP S eries products m anufactured w ith Date Code of 1415 or later (2nd w eek of Apr il

2014). These incl ude a dial-in- dial line-li ne voltage scale on the PMPU w ith an incr eased 190-500V range, n ew LED fault codes & the abilit y to set the Lin e­Line Voltage with power applied. Basic functionality & protection has been retained.

Installat ion and Wiring

1. Mount th e appropriate 8 pin oct al sock et in a suit able enclosure. NOTE: a 600V-ra ted so cket such as the Mac romati c 70169-D or

Custom Connecto r OT08-PC must be used wi th these products o n applicat ions greater t han 300V. When making connections
to the socke t, make sure to mat ch the ter minal numbers on the s ocket t o the ones show n on the w iring d iagram ( the w iring
diagram on the rel ay is t he view looking t ow ar ds the bo tto m of t he r elay vs. the to p of the s ocket ). Us e one or tw o #12-22 s olid

terminal tight ening torque of 12 in- lbs should be used.

2. Set the VOLTAGE LINE-LINE knob to the ac tual three-phas e line-to-line voltage. The
Voltage Line-Line knob on the PMPU & t he PMPU- FA8 has two ranges (s ee right ): 19 0­250V on the low voltage sc ale and 380-50 0V on the high voltage sc ale. The unit auto
senses the three-phase line-line volt age when applied and automatically select s one of
the two r anges. The PMP120 has a single adj ust able range of 102-138V and the PMP5 75
has a single adjus table range of 460- 600V.

3.(For PMPU-FA8, skip t o Step 4) Set initial settings on the UNDERVOLTAGE TRIP, TRIP
DELAY and RESTART DELAY knobs to minimum
knob to maximum.

4. Connect t he three-phase line-line voltage to termi nals 3, 4 and 5 ( see W iring Diagram on
the side of t he relay or on the back of thi s s heet). A connecti on to the neutr al or ground
is not required in Wye systems. DO NOT connect output wires to terminals 1, 2 and 8
until later (Step 13).

properly. Either another control device is
preventing the motor from starting or all wiring
should be checked.

Verify L1, L2 and L3 (A, B & C) are connected
to terminals 3, 4 and 5. Measure the three line­to-line voltages. If any of the voltages are
below the specified minimum operation
voltage, the relay does not have enough power
to operate. Check to see why operating
voltage is low and correct.

The relay is sensing a phase reversal or phase
out-of-sequence (rotation) condition. REMOVE
THREE-PHASE VOLTAGE and switch any two
of the three line connections to ensure the
phase sequence (rotation) is correct.

Make sure all three phases are present.
Check for a blown fuse or a loose or broken
wire. Measure all three line-line voltages and
calculate the percent unbalance—compare to
UNBALANCE knob setting. Determine why
unbalanc ed condition exists and correct it.

average of these three voltages is below the
UNDERVOLTAGE TRIP knob setting, the relay
has tripped due to a low voltage condition.
Check for low voltage condition and correct it.

average of these three voltages is > 10% of the
VOLTAGE LINE-LINE knob setting, the relay
has tripped due to a over voltage condition.
Check for high voltage condition and correct it.
