INTRODUCTION

The UM30 relay provides all of the voltage and

frequency-related functions necessary for the protection

of a feeder or rotating equipment. Two digital inputs are

available to provide selective blocking of various

functions. Five output relays are provided, of which four

are programmable. All settings, measurements, and

programming of the relay are possible through its front

panel controls, or by means of a computer connected to

the relay’s RS485 communications port. The functions

provided by the UM30 are:

nTwo frequency elements each configurable as either

under (81U), over (81O), or under and over (81U and

81O) elements.

nTwo overexcitation elements (24).

nTwo voltage elements each configurable as either

under (27), over (59), or under and over (27 and 59)

elements.

nOne positive sequence voltage element configurable

as either an under (27pos), over (59pos), or under

and over (27pos and 59pos).

nOne negative sequence overvoltage element

(59neg).

nTwo zero sequence overvoltage elements (59zero),

with indication of the faulted phase.

The UM30 offers two programmable inputs, which can

serve to block the operation of the over and under

protective elements.

Separate pickup functions are also provided for all

elements which may be used to operate output relays to

in order to implement various control, blocking, logic, or

SCADA functions.

HANDLING

As with any piece of electronic equipment, care should be

taken when handling the relay, particularly in regards to

electrostatic discharge as the damage may not be

immediately obvious. All Edison relays are immune to

electrostatic discharge when left in their protective case.

However, when the relay is removed from its case, the

following practices should be observed.

nTouch the case to ensure that your body and the

relay are at the same potential.

nWhenever possible, handle the exposed relay by the

front panel, the rear connector, or by the edges of the

printed circuit boards. Avoid touching the individual

electronic components or the embedded traces on

the circuit boards.

nIf you must hand the exposed (i.e., drawn-out) relay

to another person, make sure you are both at the

same electrical potential.

nWhen setting the drawn-out relay down, make sure

the surface is either anti-static in nature or is at the

same electrical potential as your body.

nRelays should always be placed in storage in their

protective cases. If storage of the drawn-out relay

outside of its protective case is required, then the

UM30 Relay operations manual

exposed relay should be placed in a suitable anti

static plastic or foam container.

INSTALLATION

Edison ‘M’ Series relays are shipped either in single or

double width cases, or in standard 19” 3RU rack mount

enclosures capable of housing up to four ‘M’ Series

relays. The double case mounting is similar to the single

case, but requires a 235 x 142mm panel opening. The

19” rack mount case is a standard 3RU high 19” cabinet.

See catalog section 150-00 for cabinet dimensions.

To remove the relay from its case, refer to Figure 1. The

relay may be removed from its protective case by turning

with a flat bladed screwdriver the locking screws Àand Á

on the front panel latches Âso that the slot on the screw

is parallel to the ground. The latches may then be pulled

from the inside edge to release the relay. Carefully pull on

the latches to remove the relay from the housing.

To re-install the relay in its case, align the printed circuit

boards with the guides in the relay case and slide the

relay in most of the way. For single and double cases,

make sure the locking arm on the back of each of the

latches Âlines up with the locking pins in the case. Then

push the latches in, seating the relay. Turn the screws on

the latches until the slot is perpendicular to the ground.

ELECTRICAL CONNECTIONS

Power is supplied via terminals 12 and 13, with common

at terminal 44. Chassis ground is made via the external

screw provided on the case. All Series ‘M’ relays are

available with one of two autoranging power supplies.

Descriptions of the input voltage ranges are given in

Table 1. The input supply voltage is noted on the relay

case. In the event the relay is fitted with the incorrect

power supply, the power supply boards are easily field

replaceable. See Bulletin S150-99-1 for instructions and

part numbers.

(+15%) 50/60 Hz

H90V (-20%) to

250V (+20%) 80V (-20%) to 220V

(+15%) 50/60 Hz

All electrical connections, including the RS485

connections, are made on the back of the relay. See

Figure 2. All the terminals will accept up to a No. 6 stud

size spade connector (or any type of lug up to 0.25”

wide), 12 AWG wire (4 mm²), or FASTON connectors.

Electrical connections must be made in accordance with

the relay’s wiring diagram found in Figure 3. The

numbers next to the circles along the edge of the

functional block diagram of the relay indicate the terminal

numbers corresponding to the terminal numbers on the

back of the relay as shown in Figure 2. The VT inputs

must provide the relay with phase-to-ground voltages per

the phase rotation shown.

OUTPUT RELAYS

Output relays 1 through 4 are user programmable to

operate in conjunction with the tripping of any protective

element or elements. Relay 1 (R1) consists of two

isolated SPST (one From A and one Form B) terminals

as being either normally open or normally closed. The

other three output relays, R2, R3, and R4, all have Form

C (i.e., SPDT) contact arrangements.

Output relay 5 is normally energized (shown de-

energized) and operates only upon power supply failure

or on an internal relay fault.

BLOCKING INPUTS

The UM30 has two inputs, which perform blocking

functions. The open circuit voltage across the terminals

of these inputs is 15 VDC. The internal resistance is 2.2 k

Ω. When the external resistance across these terminals

is less than 2.0kΩ, they are considered to be shorted.

See Programming the Relay for more information on the

function of these inputs.

TARGET DESCRIPTION

The front panel of the UM30 contains eight LEDs, which

act as the targets for the relay elements. The top row of

four targets correspond to frequency, voltage, positive

sequence voltage, and negative sequence voltage

respectively. As soon as the measured quantities exceed

the trip level defined by the respective programming

variable, the appropriate LED begins to flash. Once the

time delay associated with that element has expired, the

relay will have tripped and the LED goes to a constant

ON state.

The two center RED LEDs on the bottom row correspond

to the volts/Hz and the zero sequence voltage elements.

The left most yellow LED will blink when the relay is in

programming mode and will illuminate constantly when

an internal relay failure has occurred. The right most

yellow LED will flash when either of the two blocking

inputs is active.

In case of an auxiliary power supply failure the status of

the targets is recorded to non-volatile memory. The

status of the targets is maintained when auxiliary power

is restored.

KEYBOARD OPERATION

All measurements, programmed settings, and recorded

data may be accessed through the front panel. The five

buttons are color-coded and their sequence of operation

is indicated on the front panel by means of arrows

directing the user to the next appropriate button to press.

Figures 4 and 5 give an overview of the keyboard

operation.

PROGRAMMING THE RELAY

The relay may be programmed from the front panel or by

external computer control. This section will describe the

procedure for setting the relay from the front panel.

Consult the program’s User’s Manual for instructions on

programming the relay via software.

Two programming modes are available. The first is the

SETTINGS mode, where all of the input parameters (e.g.,

VT ratio, rated frequency) and settings (e.g., time delays,

etc.) are set. The second is the FèèRelay mode where

the various output relays are assigned to the various

protective elements. To enter program mode, follow

these steps:

1. Press the MODE button, to get into PROGRAM

mode.

2. Press the SELECT button to obtain either the

SETTINGS or FèèRelay display.

3. Using a thin tool (e.g., a small screwdriver) press

the recessed PROG button. The PROGRAM LED

will now be flashing, indicating that the

PROGRAM mode has been successfully entered.

CHANGING A SETTING

Once in active PROGRAM SETTINGS mode, you may

now change the relay settings. For instructions on

changing the output relay assignments see the section

titled Changing Output Relay Assignments. Change the

settings as follows:

1. Press the SELECT button to scroll through the

various input parameters available for

programming.

2. When the desired parameter to be changed is

displayed, press the +and –buttons to change

the displayed value. For numerical values where

the range of settings is large, the display may be

sped up by pressing the SELECT button at the

same time the +or – is pressed.

3. When the desired value in displayed, press the

ENTER/RESET button to store the new setting for

that parameter.

4. Repeat steps 1-3 for each setting.

5. When finished, press the MODE button to leave

programming mode and return the relay to normal

operation.

DESCRIPTION OF RELAY SETTING VARIABLES

This section describes each variable in the PROGRAM

SETTINGS mode. The following conventions are used:

•The name of the variable and any unit of

measure displayed (Volts, Hz, etc.) is in bold

face type. Some variables do not have a unit

of measures displayed. An example of these

are variables that define curve shapes.

•The default value is shown in regular

typeface.

For example: Fn 50Hz

A value of “Dis” in the Setting range column indicates that

when the variable is set to this value, the related function

is disabled.

Fn is the name of

the variable. Hz is the unit of

measure, Hertz.

50 is the setting

default.

BLOCKING VARIABLES

Two blocking inputs are provided. One input is dedicated

toward blocking all “under level” functions, and one

dedicated to blocking all “over level” functions as follows:

Blocking input BI>:shorting terminals 1 and 2

activates This blocking input. The operation of any output

relay controlled by an “over level” function is inhibited for

as long as the input terminal pair is shorted. This includes

any over-frequency, over-voltage, positive sequence

over-voltage, negative sequence over-voltage, zero

sequence over-voltage, and over-volts/Hz elements.

Blocking input BI<:shorting terminals 1 and 3

activates This blocking input. The operation of any output

relay controlled by an “under level” function is inhibited for

as long as the input terminal pair is shorted. This includes

any under-frequency, under-voltage, and positive

sequence under-voltage.

While the blocking inputs are active (i.e., shorted), the

tripping of any element associated with the blocking

input(s) is prevented. Continued sensing of the input

quantities and the countdown of any timers continues

however, so that when the blocking is removed, any

picked up elements will either trip instantaneously, or will

trip after any remaining time delay.

PROGRAMMING VIA SOFTWARE

The UM30 may also be programmed using any of the

programming interface software packages provided by

Cooper Power Systems or others. Please consult the

user manual for the appropriate software.

The UM30 uses the Modbuscommunication protocol.

For details on the memory map used in the UM30 in

order to interface it with other Modbus programs or

devices, consult the Edison ‘M’ Series Relay Technical

Reference Manual.

RUNNING THE TEST PROGRAMS

If desired, the start up diagnostic routines may be run at

any time by accessing the TEST PRG mode. Two tests

may be run, both of which are identical except for the

effect on the output relays.

1. Press the Mode button until TEST PRG is displayed.

2. Select the test to run by pressing the SELECT button

once to show LEDSONLY, or twice to display

LED+TRIP.

A. If the LEDSONLY test is selected, pressing the

ENTER/RESET button will run the test. All the

LEDs should illuminate during the duration of the

test. If an error is found, the error code will be

displayed and the RELAY FAIL light will remain

illuminated. The test lasts approximately five

seconds. No output relays will operate or change

status.

B. If the LED+TRIP test is selected, pressing the

ENTER/RESET button will then display

TestRun? To run the test the ENTER/RESET

button must be pressed again. At this point the

test will run and all of the output relays will also

be operated. The test lasts approximately five

seconds.

An external computer running the appropriate software

may also initiate these test routines.

REAL TIME MEASUREMENTS

To display the real-time measured values of the relay’s

quantities, enter the ACT MEAS mode of operation as

follows:

1. Press the MODE button, to get into MEASURES

mode.

2. Press the SELECT button to select the ACT

MEAS mode.

CAUTION

Running the LED+TRIP test will operate all of the

output relays. Care must be taken to ensure that no

unexpected or harmful equipment operations will occur

as a result of running this test. It is generally

recommended that this test be run only when all

dangerous output connections are removed.
