About This Document
General Purpose
This document is the Operator’s Manual for Murphy’s Automatic Genset Controller, the
EMS-GC10.
The general purpose of the Installation Manual is to provide the information needed to
operate the unit.
WARNING: Please make sure to read this document before working
with the EMS-GC10 controller and the Genset to be controlled.
Failure to do this could result in human injury or damage to the
equipment.
You may visit the Murphy website at http://www.fwmurphy.com/emsgc10 to download the
latest version of the configuration tool software and the EMS-GC10 Operator’s Manual part
number 00-02-0878.
You will need to purchase the TTL to USB cable (75000277) in order to use the Utility Software
(USW).
Intended Users
The document is intended for the person responsible for setup and operating the EMS-GC10
unit.
Address, Menu, Setting, Parameter
To promote consistently with the PC Configuration Tool called Utility Software (USW), this
document uses the word Parameter, where in some instances, may also be thought of as an
address, menu, or setting.

Warnings and Legal Information
Legal Information and Responsibility
FW Murphy takes no responsibility for installation or operation of the generator set. If there is
any doubt about how to install or operate the engine/generator controlled by the EMS-GC10
unit, the company responsible for the installation or the operation of the set must be
contacted.
IMPORTANT: The EMS-GC10 unit is not to be opened by
unauthorizedpersonnel. If this occurs, the warranty will be void.
Disclaimer
FW Murphy reserves the right to change any of the contents of this document without prior
notice.
Electrostatic Discharge Awareness
Sufficient care must be taken to protect the terminals against static discharges during the
installation. Once the unit is installed and connected, these precautions are no longer
necessary.
Safety Issues
Installingand operating the EMS-GC10 unitmay imply work with dangerous currentsand
voltages. Therefore, the installation should only be carried out by authorized personnel
who understand the risks involved in working withlive electricalequipment.
WARNING: Be aware of the hazardous live currents and voltages.
Do not touch any AC measurement inputs as this could lead to
injury or death.
Factory Settings
The EMS-GC10 unitis delivered from the factory withcertainfactory settings. These are based
on average values and are not necessarily the correct settings for matching the
engine/generator set in question. Precautions must be taken to check the settings before
runningthe engine/generator set.
NOTE: When the controller unit operates for the first time after it has been
received from the factory, both mains and generator breakers alarms will
be activated to warn the user (shown as fault), until they are connected to
the power system and reset accordingly.

Introduction
This Operator's Manual includes general product information, display readings, push-
button, LED functions, alarm handling descriptions, and presentation of the log list. This
manual is intended to help optimize the operator s daily use. On the basis of this
document, the operator will be able to carry out simple procedures such as start/stop
and control of the generator set.
As a Reference point: Please note that the "U" symbol is also used as an
indication for the voltage.
EMS-GC10 delivers field-adjustable operating parametersbut may require further
configuration using the Utility Software. It can support both mechanical and J1939
electronic engines.
The EMS-GC10 is ideal for use with a remote modem or in a SCADA system offering
Modbus® RTU protocol on the RS485 port.
Product Description
The EMS-GC10 Genset Controller provides flexible control and monitoring for industrial
genset applications. Typical applications include backup power, power supply for
remote locations without a connection to power grid, and mobile power for remote
locations. The controller supports programmable logic, up to 40 expressions, and can
be configured for specific predefined functions unique to your application.
The EMS-GC10 supports Automatic Mains Failure (AMF) and generator breaker
control.
The EMS-GC10 offers field-adjustable operating parameters that can be changed
through the controller or an easy to use PC configuration tool called Utility Software

Running Modes
The unit has four different running modes and one block mode. The different running
modes are four to three via the display or the PC utility software.
Auto
In auto mode, the unit will operate automatically, and the operator cannot
initiate any sequences manually.
Test
The test sequence will start when the test mode is selected.
Manual
Manual means that the unit will not initiate any sequences automatically,
as is the case with the auto mode. It will only initiate sequences, if
external signals are given.
Block
When the block mode is selected, the unit is not able to initiate any
sequences, for example, the start sequence.
NOTE: Block mode must be selected when maintenance work is
carried out on the Genset.
NOTE: The Genset will shut down if block mode is selected while
the Genset is running
NOTE: If the auto button is pressed twice, the controller will be in
the semi-auto mode. This mode is not supported, and is the same
as the manual mode. Press either the auto or manual button once
to resume normal operation
Alarm and Logs
When an alarm occurs, the alarm is displayed and saved in the Alarm Log.
Press the ESC button to hide the alarm from the display.
Press the ENTER button to acknowledge the alarm.
NOTE: When you acknowledge an alarm, and the alarm condition
is no longer present, the alarm will no longer be displayed in the
Alarm Log .
Press the HORN button for 2 seconds to view the list of alarms stored in the alarm
log. Press the UP and Down Buttons to view the list.
NOTE: The display will show one alarm at a time.
The alarm log contains both acknowledged and unacknowledged alarms provided that
they are still active (i.e. the alarm condition is still present).

Section 75 00-02-0878
2013-03-07 - 13 -
If there are no alarms, the Alarm List (Log) will be empty.
The display example below indicates an unacknowledged alarm. This means: Bus
Bar U > Settings Group 1
Log List
The log is divided into three different lists:
•Event Log – closing of breaker and starting of engine
•Alarm Log – overcurrent or high cooling water temperature
•Battery Test Log – test OK or test failed
The event log contains up to 50 events, the alarm log contains up to 30 historical
alarms and the battery test log contains up to 52 historical battery tests.
Parameters—Only Available With USW
Parameters need to be configured through the Utility Software (USW) and not locally
available to be configured from EMS-GC10 unit.
