Introduction

This document is designed to support a user in getting familiar with the iGUARD Digital

Generator Set Controller and how to navigate the interface, modify the settings and install and

operate the controller. Before attempting to set up the controller, be sure to read and

understand this manual in its entirety.

Product Description

Description

The iGUARD controller is a high performance, state of the art, digital generator set controller.

This robust controller features high-speed microprocessors, and high accuracy AC

measurements. The iGUARD is a menu driven system, organized by "stacks", with "sub-

stacks" where required. User connections are made via the plug in connectors on the rear of

the controller. The iGUARD controller has a textured finish; UV stabilized polycarbonate

injection molded housing, and is sealed with an “o” ring to help protect the iGUARD from the

environment. There is a back cover protecting the Energy monitoring Board (EMB) to prevent

contact with circuit board components and potentially harmful AC voltage wiring.

User Interface and Navigation

The keypad on the iGUARD is a capacitive touch sensing system. There are no mechanical

switches to wear or stick, and the technology has been time proven in many applications. It

operates in extreme temperatures, with gloves, through ice, snow, mud, grease, etc., and it

allows complete sealing of the front of the iGUARD. It does operate slightly differently than a

membrane keypad, in that there is no tactile feedback. The ‘key is pressed’feedback is

provided by momentarily beeping the audible alarm. The keys on the keypad do the following

functions:

START In Manual mode pressing the start pad will cause

the engine to start. In automatic mode the screen

will display an error message that system must be

in manual mode to start with the start button.

STOP In automatic or manual mode pressing the stop pad

will stop the set. The system is forced into a

manual mode, and will not autostart until returned

to automatic mode.

Auto/Manual Selects manual (sometimes-called local) operation

or automatic mode (system monitors a digital input

for a start signal).

Acknowledge/Alarm For warnings that do not cause a shutdown,

pressing this pad will clear the alarms active at that

moment. If the conditions subsequently clear and

re-occur or if additional warnings occur, the

common alarm output will come back on.

Up / Down Arrows In program mode scrolls the menu selections and

also scrolls through the choices for a given

parameter.

Left / Right Arrows In normal operation steps forward/backward

through the screens available in the active

submenu

Next In normal operation steps forward through the main

menu selection

Back In normal operation steps backward through the

main menu selections.

Enter In program mode, pressing Enter will allow a

variable to be changed, and then pressing Enter

again will accept the displayed /new value.

Exit In normal operation returns the system to the main

(default) screen. In program mode cancels any

changes made unless the "Enter" pad has already

been pressed.

iGUARD Operating Instructions

Operating Sequence

The iGUARD controller, while reprogrammable, follows a standard operating sequence. This

operating sequence is basically a set of machine states that happen in a pre-determined order.

Machine states can be set to zero if not needed, or adjusted to fit the application. For the basic

operating sequence, see the iGUARD Sequence Appendix in the Installing the

Mimic/Annunciator DM/A section, this document. The iGUARD operating sequence includes

the following modes:

Ready to Start Mode Automatic start mode ready for a contact closure to initiate an

automatic start and run sequence.

Prestart Delay Mode A timer used to prevent nuisance starts, or to warn nearby

personnel that automatic equipment is about to start (set to 0

to bypass).

Prelube Mode In larger generators there may be a requirement for

automatic lubrication prior to cranking (set to 0 to bypass).

Preheat Timer set to provide the correct amount of precrank operation

of the air intake heaters used to facilitate starting in cold

conditions. (Set to 0 to bypass).

Cranking / Crank Rest Mode Engine is attempting to start and will go through the number

of selected starting attempts.

Crank Disconnect / Engine

Running Mode Engine speed is greater than the crank disconnect.

Warmup Mode Timer to allow system to run unloaded for selected time (set

to 0 to bypass).

At Load Mode Generator is running at load.

Power Good Mode This mode is to prevent nuisance start/stops. The controller

continues running but monitors the remote start contact while

in this mode. The power good timer must expire before the

system can proceed to cooldown. Any further call to run

resets the power good mode timer to its preset value.

Cooldown Mode Generator runs unloaded for a preset time.

Energized to Stop The Energized to Stop timer is ON and the Energized to Stop

output is active.

Stopped Mode Generator has come to a complete stop.

Postlube Mode In larger generators there may be a requirement for

automatic lubrication after a normal start/run/stop cycle

before the engine can be restarted (set to 0 to bypass). After

postlube, the system returns to Ready to start. Additionally

there are two fault shutdown modes:

Shutdown / Lockout with Cooldown Mode - In

the case of some faults the controller will open the

"at load’contact and then go through a normal

cooldown and stop sequence, but will not allow an

automatic restart without a system reset.

Immediate Shutdown/Lockout (no Cooldown)

Mode - Because of the severity of most faults, the

controller will cause an immediate

Shutdown/Lockout without a cooldown period, and

will not allow an automatic restart without a system

reset.

Shutdown / Lockout with

Cooldown Mode In the case of some faults the controller will open the "at

load’contact and then go through a normal cooldown and

stop sequence, but will not allow an automatic restart without

a system reset

Immediate

Shutdown/Lockout (no

Cooldown) Mode

Because of the severity of most faults, the controller will

cause an immediate Shutdown/Lockout without a cooldown

period, and will not allow an automatic restart without a

system reset.

Programming the iGUARD from the Keypad

The iGUARD controller can be programmed in two separate ways. Most setup can be done

from the front panel. There are some parameters, such as changing passwords that require

the use of the iGCON software tool. The iGUARD programming menus can be accessed at

any time by pressing the left and right arrows at the same time. This will bring up the password

menu:

The factory defaults (and what they allow access to) for the various levels of password are:

Access Security - Allows input of 4-character security code.

PASØ - No operational Access. It allows viewing of the data screens but

parameters cannot be edited.

PAS1 - Operational Access. It allows Manual Start and Stop but parameters

cannot be edited.

PAS2 - Parameter View Access. Allows for viewing of all parameters and

editing of the following parameter settings:

Change Language

Key Sensitivity Level

Back Light On/Off

Ack Maintenance Timers

Enable Beeper

Select Pressure Units

Select Temperature Units

Modify Date

Edit Clock Start and Stop Timers

PAS3 - Parameter Edit Access. Allows for viewing and parameter editing

but does not allow calibration of AC.

PAS4 - Calibration Access. Allows calibration of the AC parameters.

PAS5 - kW Limit Edit and Config Select Access. Allows editing of kW limits

and various communication addresses.

What to do if you lose your Password

Press NEXT until you see the screen with a graphic display of the Murphy logo. Press NEXT

once to go to the system information screen.

Write down the serial number, the current date, and time showing on the real time clock

display, and contact us (918) 317-4100, ask for technical support). We will provide a temporary

password that will allow you to access the system to recover the passwords.

Acknowledging Maintenance Timers

Status/ Warning Screen - You may see this warning/status message:

This is information that one or more of your maintenance reminder timers has expired. To

acknowledge the warning and reset the timer, enter the programming mode, and go to the

Miscellaneous Parameters screen.
