Macromatic PMP Series Bedienungsanleitung

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 ﬂash GREEN if in theAutomatic 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 ﬂashing, 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.

LED STATUS SITUATION SOLUTION

GREEN Motor is not starting

Either (a) the relay is going through its POW-

ER-UP/RESTART delay and will energize the

output contacts when completed; or (b) the relay

is in the Manual Reset mode and waiting for an

external switch to be operated before energizing

the output contacts (all, but PMPU-FA8X &

PMPU-FA12X, which is auto-reset only).

GREEN Motor is not starting

The relay is in the run mode and working properly.

Either another control device is preventing

the motor from starting or all wiring should be

checked.

NO INDICATION

Relay is not energized

and/or motor is not

running

Verify L1, L2 and L3 (A, B & C) are connected to

correct terminals. Measure the three line-to-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.

RED On power-up or with

motor running

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 the relay to

ensure the phase sequence (rotation) is correct.

RED Either a phase loss

or voltage unbalance

condition

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 unbalanced condition

exists and correct it.

RED Low voltage

(Undervoltage)

Measure the three line-to-line voltages. If the

average of these three voltages is below the

UNDERVOLTAGE TRIP knob setting, the relay

has tripped due to a low voltage

RED High voltage

(Overvoltage)

Measure the three line-to-line voltages. If the

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.

Operation

13. Connect the output terminal wires to terminals 1, 2 and 8 (terminals 1, 2, 6, 7 and 8 for PMPU-FA8X and terminals 7-12 on PMPU-FA12X). See

Wiring Diagram on the side of the relay or below.

14. When all connections are made, apply three-phase line-line voltage. The LED indicator should initially ﬂash GREEN while the relay goes through its

restart delay or waiting for an external switch to be operated if in the Manual Reset mode (all, but PMPU-FA8X & PMPU-FA12X, which is auto-reset

only) and then illuminate solid GREEN when all voltage conditions are correct.

15. If the LED does not illuminate solid GREEN during regular operation, a fault condition has occurred. REMOVE THREE-PHASE VOLTAGE, and

check for proper phase rotation, presence of all three phases, and low or high voltage conditions. Use the LED Status Table on the ﬁrst page

or the Troubleshooting Guide below to determine exact cause of fault. Correct if necessary. Re-energization is automatic upon correction of

the fault condition unless using MANUAL RESET (all, but PMPU-FA8X & PMPU-FA12X, which is auto-reset only) which requires opening the N.C.

switch across terminals 6 and 7 to reset the unit (see Step 5).

Troubleshooting

If the unit fails to operate properly, check that all connections are correct per the appropriate wiring diagram on the product. Check Troubleshooting table
