macromatic PMP Series Installation Instructions

December 2017, Rev D
(Replaces September 2017, Rev C)
Potentially hazardous voltages are present. Electrical shock can cause death or serious injury.
Installation should be done by qualifi ed personnel following all National, State & Local Codes.
BE SURE TO REMOVE ALL POWER SUPPLYING THIS EQUIPMENT BEFORE CONNECTING OR DISCONNECTING WIRING.
READ INSTRUCTIONS BEFORE INSTALLING OR OPERATING THIS DEVICE. KEEP FOR FUTURE REFERENCE.
IMPORTANT: READ THIS FIRST IF REPLACING A PMP SERIES PRODUCT WITH DATE CODE OF 1414 OR EARLIER
Macromatic made several product design enhancements on all PMP Series products manufactured with Date Code of 1415 or later (2nd week of April 2014).
These include a dial-in-dial line-line voltage scale on the PMPU with an increased 190-500V range, new LED fault codes & the ability to set the Line-Line Voltage
with power applied. Basic functionality & protection has been retained. For more information, please visit www.macromatic.com/new-pmp
Installation and Wiring
1. Mount the appropriate 8 pin octal socket in a suitable enclosure. NOTE: A 600V-rated socket such as the Macromatic 70169-D or Custom
Connector OT08-PC must be used with these products on applications greater than 300V (PMPU-FA12X requires Custom Connector
SD12-PC 600V socket). When making connections to the socket, make sure to match the terminal numbers on the socket to the ones
shown on the wiring diagram (the wiring diagram on the relay is the view looking towards the bottom of the relay vs. the top of the
socket). Use one or two #12-22 solid or stranded copper or copper-clad aluminum conductors with terminals on the above Macromatic or Custom
Connector sockets—a terminal tightening torque of 12 in-lbs should be used.
2. Set the VOLTAGE LINE-LINE knob to the actual three-phase line-to-line voltage. The
Voltage Line-Line knob on the PMPU, PMPU-FA8, PMPU-FA8X & PMPU-FA12X has two
ranges (see right): 190-250V on the low voltage scale and 380-500V on the high voltage
scale. The unit auto senses the three-phase line-line voltage when applied and automat-
ically selects one of the two ranges. The PMP120 has a single adjustable range of 102-
138V and the PMP575 has a single adjustable range of 460-600V.
3. (For PMPU-FA8, PMPU-FA8X & PMPU-FA12X, skip to Step 4) Set initial settings on the
UNDERVOLTAGE TRIP, TRIP DELAY and RESTART DELAY knobs to minimum. Set initial
setting on the UNBALANCE knob to maximum.
4. Connect the three-phase line-line voltage to terminals 3, 4 and 5 (1, 3 and 5 on PMPU-FA12X).
See Wiring Diagram on the side of the relay or on the back of this sheet. A connection
to the neutral or ground is not required in Wye systems. DO NOT connect output wires to
terminals until later (Step 13).
5. (For PMPU-FA8X & PMPU-FA12X, skip to Step 6) RESET: As standard, the PMP Series
relays are in the Automatic Reset mode, which means they will automatically reset once
the fault has been corrected. However, they can be set up in the Manual Reset mode by
connecting an external N.C. switch across terminals 6 and 7. Upon application of three-phase voltage, the PMP Series will go into Manual Reset
mode if it recognizes a closure across terminals 6 and 7. After a fault clears, the relay will not reset until the N.C. switch is opened. NOTE: When
the unit is in the Manual Reset mode, the N.C. switch must be opened after each Power-up to reset the relay and resume normal operation. NOTE:
This unit can only be set back to Automatic Reset mode from Manual Reset mode by removing three-phase voltage, removing the N.C. switch
across terminals 6 and 7, and reapplying the three-phase voltage.
6. Plug the three-phase monitor relay into the socket, making sure the key on the center post is in the
proper orientation before insertion. If the relay must be removed from the socket, do NOT rock
the relay back and forth excessively—the center post could be damaged.
7. Apply three-phase voltage. The LED indicator should initially fl ash GREEN if in the Automatic Reset
mode while the relay goes through its start-up delay or waiting for an external switch to be operated
if in the Manual Reset mode and then illuminate solid GREEN (Manual Reset mode does not apply
to PMPU-FA8X or PMPU-FA12X). If the LED turns RED solid or fl ashing, a fault condition exists and
must be corrected. Use the LED Status Table at right or the Troubleshooting Guide on back to
determine exact cause of fault. Make required corrections.
Settings
8. REMOVE THREE-PHASE VOLTAGE for Steps 9-13 (For PMPU-FA8, PMPU-FA8X & PMPU-FA12X, REMOVE THREE-PHASE VOLTAGE and
skip to Step 13).
9. Set the RESTART DELAY knob. This setting should be the time period required after a fault has been cleared before the relay should automatically
energize. NOTE: this value is ignored when in the Manual Reset mode (see Step 5).
10. Set the UNDERVOLTAGE TRIP knob between 80 and 95% of the line-line voltage setting. This value should be the same as the minimum
operating voltage for the equipment to be adequately protected.
11. Set the TRIP DELAY knob. This is the maximum time period that an unbalance, undervoltage or overvoltage condition should be allowed to last.
Too short a setting will cause nuisance tripping if there are momentary changes in the three-phase voltage. Too long a setting could cause damage
to the equipment. Note that the setting should be at least slightly longer than the time a three-phase motor is drawing its inrush or startup current.
This will avoid nuisance tripping caused by the starting current.
12. Set the UNBALANCE knob. This setting should be the maximum allowable unbalance in phase voltage that the three-phase system can tolerate.
Too low of a setting can cause nuisance tripping. Too high of a setting may not adequately protect the system.
DANGER!
