WARNING
Read this entire manual and all other publications pertaining to the work to be performed before instal-
ling, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage,
and (ii) invalidate product certifications or listings.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
•Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
•Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

General Information
Introduction
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The MFR 3 has been designed to provide circuit breaker and load control and protection. It is possible to monitor
both the generator and mains simultaneously. The MFR 3 permits two circuit breakers to be synchronized and
control of the mains power.
The MFR 3 starts as a standard unit that may have additional functions added with each model. The model of the
MFR 3 is designated as follows:
MFR3S45-h0018B/PSV -ABDEF..Z
Options according to list of options:
These options can be found in the manual. Each chapter headline points out
if the described function is standard or is an option.

time clock)

Intended Use: The control unit must only be operated as described in this manual. The prerequisite for a proper
and safe operation of the product is correct transportation, storage, and installation as well as careful operation
and maintenance.
NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens and other details described, which do not exist on your unit may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. Be-
cause of the large variety of parameter settings, it is not possible to cover every combination. The ma-
nual is therefore only a guide. In case of incorrect entries or a total loss of functions, the default set-
tings can be taken from the enclosed list of parameters at the rear of this manual.

Measuring
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Voltage
The control unit performs three-phase true RMS measurement of two star or delta voltage systems (generator
and mains). This unit can be delivered with the following measuring voltage ranges (rated values). The vol-
tage measuring is specific to the part number ordered (please note chapter "Technical Data", page 138):
- [1] 66/115 Vac
- [4] 230/400 Vac
Frequency
The measured voltages are digitally filtered for frequency measurement. The control unit performs three-
phase true RMS measurement of the frequency if the measured voltages exceed the rated value (100/400 Vac)
by 15 %. This ensures rapid and precise measurement of the frequency. Frequency is still measured correctly
if voltage is only measured in one phase.
Current
The control unit performs three-phase true RMS current measurement.
Real power
The control unit performs three-phase true RMS power measurement. This is accomplished by real-time mul-
tiplication of the wye voltage and instantaneous conductor current values (three-phase measurement) or the
phase voltage VL12 and the current IL1 (single-phase measurement).
Re-active power
The control unit performs single-phase true RMS re-active power measurement, which is calculated from ap-
parent power and active power.
Power factor
Power factor is determined as a time measurement between the filtered measured values of the voltage VL12
and the conductor current IL1.
Real energy
The positive real energy is integrated with a time measurement. The counter is controlled in the non-volatile
memory and has reverse counting protection. The data is saved in three-minute time frames with a resolution
of 1 Watt-hour. The display automatically updates the measured units when required to go to a larger refer-
ence. This permits the control unit to count up to 4,290 GWh. The counter is not PTB-calibrated.

Chapter 2.
Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others. To protect these components
from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1. Before performing maintenance on the electronic control, discharge the static electricity on your body to
ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials.
Wear cotton or cotton-blend materials as much as possible because these do not store static electric
charges as much as synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette
packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from
the control, the modules, and the work area as much as possible.
4. Opening the control cover may void the unit warranty.
Do not remove the Printed Circuit Board (PCB) from the control cabinet unless absolutely necessary. If
you must remove the PCB from the control cabinet, follow these precautions:
•Ensure that the device is completely de-energized (all connectors must be disconnected).
•Do not touch any part of the PCB except the edges.
•Do not touch the electrical conductors, connectors, or components with conductive devices with your
hands.
•When replacing a PCB, keep the new PCB in the protective antistatic bag it comes in until you are
ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the
protective antistatic bag.
CAUTION
To prevent damage to electronic components caused by improper handling, read and observe the pre-
cautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed
Circuit Boards, and Modules.

Installation
CAUTION
A circuit breaker must be provided near to the device and in a position easily accessible to the opera-
tor. This must also bear a sign identifying it as an isolating switch for the unit.
NOTE
Connected inductive devices (such as operating current coils, undervoltage tripping devices, or aux-
iliary or power contacts) must be connected to a suitable interference suppressor.

CAUTION
Before disconnecting the secondary current transformer (CT) connections or the connections of the CT
at the device, make sure that the CT is short-circuited.
NOTE
Generally current transformers should be grounded on one side.
