Instruction for the
Cutler-Hammer Type MPCV
Network Protection Relay
RESET TIME
With the PUMP PROTEC=ON, the program will ask for a
breaker reset time, which is initiated if the BRK CYCLES and
PUMP TIME are exceeded in value. The breaker, through the
relay, will trip and lock out, thereby preventing a reclosure. The
reset time has a default value of 15 minutes, but is capable of
being extended up to 60 minutes with the pendant controller in
1-minute increments (10 minutes with larger arrow). The reset
time permits the closing motor to cool its field coils before call-
ing on the motor to attempt another breaker closure, thereby
extending the useful life of the network breaker closing motor.
Make your selection and enter the NEXT key to view the next line.
The following pendant inputs deal with the communications
information. If the MPCV Relay is not connected to an operat-
ing communications system, the following set points can be
by-passed by entering the SAVE button at this time.
If the communication system will be or now is operational,
the following set points must be entered.
AUX 2 OFF/ON
If you are using the AUX 2 position, you must select the AUX 2
port to be ON. Once the NEXT key is entered, you must select
whether the device being monitored is going to show up on the
front end screen as an alarm (ENABLE) or only status (DISABLE).
Further, you must indicate whether the contact being utilized is
normally open (NO) or normally closed (NC). The convention
used is that the NO or NC state is that state in which the alarm
is not enabled. Changing the contact state then will ENABLE the
alarm. Refer to Pages 9 and 10 for the terminal block wiring
configuration of the AUX ports.
Repeat as required for additional AUX 3 and AUX 4 inputs.
Make your selection and enter the NEXT key to view the next line.
INCOM ADR =
This is a hexadecimal input which must agree with the relay
address as listed on the main screen of the communications
program. No two relays should have the same address code.
The code can be changed by using the large and small, up
and down arrow keys. Install this value and determine that it
matches the relay location, as determined by the system
operator, and enter the NEXT key to view the next line.
Note: If a MPCV Relay is provided with communications turned OFF,
communications can be activated in the field by a qualified Eaton ser-
vice representative.
INCOM SETPT=ON
The default setting is ON with the capability to change to
OFF. If the INCOM SETPT=OFF, this prevents a user from
remotely changing set points through the IMPACC Series
III
or PowerNet
software.
INCOM OPEN=ON
The default setting is ON with the capability to change to OFF.
If the INCOM OPEN=OFF, this prevents a user from remotely
opening the breaker through the IMPACC Series
III
or Power-
Net software. This also effectively disables the set point down-
load, as the breaker must be ROBO’d (Remote Open, Blocked
Open) before any set points can successfully be downloaded.
INCOM CLOSE=ON
If the INCOM CLOSE=ON, this permits a protected remote
close status which reduces the ML value to its operational
lowest point for a time period of 10 seconds. This requires
PowerNet software to enable this feature. Changing this
setting to OFF locks out the remote close feature.
YEAR =
The year as a two-digit number is entered. It understands 00 as
the year 2000. Use the small arrow keys to change the value.
Make your selection and enter the NEXT key to view the next line.
MNTH =
The month is entered as a number from 1 to 12. Use the
small arrow keys to change the value. Make your selection
and enter the NEXT key to view the next line.
DAY =
The day is entered as a number from 1 to 31. Use the small
arrow keys to change the value. Make your selection and
enter the NEXT key to view the next line.
HR =
The hour is based on a 24-hour military clock. Enter a number
from 00 to 24. Use the small arrow keys to change the value.
Make your selection and enter the NEXT key to view the next line.
MIN =
Enter the minutes by selecting a value from 00 to 59. Use the
small arrow keys to change the value. Make your selection
and enter the NEXT key to view the next line.

Save the entire menu selection by depressing the SAVE key.
Once the SAVE key has been de-pressed, all of the set points
will be stored within the relay’s memory. The FLOAT light will
become illuminated solid, not flashing, and the pendant screen
will clear. You have now completely calibrated the relay.
Note: With the MPCV Relay, you can change individual set points
without having to review the entire menu. Single entries can be now
changed by inserting the pendant’s RS-232 plug into the relay’s connec-
tor, enter the EDIT key and scroll down to the line you wish to change.
Once the change has been made, the SAVE key can then be de-pressed.
