WE PUT MORE INTO OUR CONTROL

so you can get more out of your gen sets

Integrate your Cat standby gen set into your building’s operating system with Cat EMCP II and EMCP II+ controls.

No generator set control has been more

reliable, more accurate or more powerful

than the Cat® EMCP II. Until now.

Introducing the EMCP II+ control. It lets you run

your Cat power generation system more efficiently

than ever – with even less hands-on attention.

The performance you expect. And more.

You know the Electronic Modular Control Panel II

for its unfailing durability; its precise metering and

state-of-the-art sensors; its complete diagnostics

and protective features; its clear, descriptive

graphics and easy-reading LEDs. The EMCP II+

gives you all that, and much more:

Information – Plus. More ways to measure,

observe and record your gen sets’ performance –

like full-featured power metering.

Protection – Plus. More capacity to defend your

gen sets against potentially damaging faults.

Flexibility – Plus. Programmable alarms,

shutdowns and relays to help you custom configure

the control for your application.

Convenience – Plus. More data available at a

glance, through one-touch display and automatic

hands-off scrolling.

Want more functionality? Just add it on.

The EMCP II and EMCP II+ interface with a series of

optional modules that give you:

• Remote monitoring and control capability.

• More ways to protect your equipment and customize

your operation.

For your next power project, the choice is yours.

Specify Cat diesel gen sets with the standard production

EMCP II. Or step up to the new generation: EMCP II+.

Cat EMCP II and EMCP II+ controls helpprotect high-tech manufacturers and other

businesses from costly power outages.

In gen set control, one quality outweighs them all:

Reliability. Cat controls are built to perform when the

going gets tough.

Reliability. Designed right in.

Not every gen set runs in a climate-controlled engine

room. So we put the EMCP II and EMCP II+ through

rigorous testing for performance in harsh environments

– the same tests used on controls in legendary Cat

earth movers.

And both controls underwent Failure Mode Effects

Analysis, a complex process with a simple purpose:

Soak it. EMCP controls are environmentally sealed in a die-cast aluminum housing, impervious to moisture and contaminants.

first,BUILT TO LAST

Find potential causes of failure, then design to

minimize them. It's a technique we borrowed

from the automotive industry.

Built tough.

Look at the result: Controls that stand up to

weather, vibration, dirt. And anything else your

workplace dishes out.

EMCP II and EMCP II+ components are

environmentally sealed in a die-cast aluminum

housing. No circuits are exposed; water, corrosives

and abrasives cannot get in. Both units have high-

level protection against short circuits, overvoltage

and transient surges. Circuitry is protected from

electrical noise, up to 100 volts/meter.

Sensors that won't quit.

The sensors are built for accuracy under any

conditions. These active sensors with on-board

electronics send digital pulse-width-modulated

(PWM) signals. The microprocessor reads signal

duration – not strength. So even if a loose or

fouled connection weakens the signal, the reading

remains accurate. What's more, the control can

diagnose and annunciate sensor faults – so if a

sensor stops working, you know it right away.

Your gen set control protects your power-system

investment. You can be sure the EMCP II or

EMCP II+ will be on the job whenever you are.

Shake it. Rigorous testing verifies that EMCP panel circuits will notvibrate loose.

Heat it. Freeze it. EMCP controls maintain metering accuracy up to70° C (158° F) and down to -40° C (-40° F).

The EMCP II and EMCP II+ give you all the

information you need to run your gen sets

efficiently and keep them on-line consistently.

Both give you metering, diagnostics and system

protection with utmost simplicity and accuracy.

You’re used to all this.The EMCP II and EMCP II+ help you track your gen

sets’ performance and detect problems before they

become serious.

True RMS (root mean square) metering means

you get precise measurement even for distorted

wave forms resulting from non-linear loads

(variable frequency drives, discharge-type lighting,

welders, computers, UPS systems). Metering

accuracy is +/- 0.5% for AC volts and amps and

+/- 0.1 Hz for frequency over a temperature range

from -40° C to 70° C (-40° F to 158° F).

A digital LCD reports engine run hours, engine

oil pressure, engine speed, coolant temperature,

system DC volts, generator AC volts and AC amps,

and generator frequency.

Flashing LED alarm indicators and safety

shutdowns protect against engine damage from

low oil pressure, high coolant temperature, low coolant

level, overspeed and overcrank.

Built-in diagnostics let you detect equipment

problems early and troubleshoot quickly and precisely.

An SAE format two-part diagnostic code identifies both

the component affected by the problem and its failure

mode. You can access diagnostics directly from the

control panel – no need for a laptop computer.

Control servicing is safe, because no high voltages

feed the front panel.

Now, get this much more.The EMCP II+ adds even more power and functionality.

Consider these capabilities:

• Full-featured power metering. View gen set (total

and per phase) kW, kWh, kVA, kVAR, kVAR hours,

percent rated power and power factor, all accessible

with one key-pad touch. Track both reactive and real

energy usage.

• Programmable protective relaying. Protect against

undervoltage, overvoltage, underfrequency,

overfrequency, overcurrent and reverse power.

Program the set points – alarm or shutdown – to fit

your application.

• Adding or shedding load. Program a load demand

relay to open and close to start or shut down a gen

set based on generator kW output. Establish your

own set points.

• Easy data scanning. View engine and generator

parameters at the same time. Toggle between

individual parameter display and automatic,

hands-off parameter scrolling.

• Enhanced display. View all AC L-L voltages, all

AC L-N voltages, or all AC line currents.

Get 10 LED alarms, three programmable for your

own inputs.

• More flexibility. Select the display voltage and

current best suited to your site. Program the

control to respond to inputs from external tanks,

limit switches, ventilation louvers and many

other devices.

Now, you can complete your EMCP II or EMCP II+

control system with a series of programmable

modules available from Caterpillar.

Reach around the globe.

The Customer Communication Module lets you

dispatch, remotely monitor and control as many

as eight generator sets by satellite or phone line.

Without leaving your desk, you can:

• View real-time readouts on all generator and

engine functions.

• Start and stop gen sets; reset alarms and

shutdowns.

CUSTOM MODULES

to add more power

• Track alarms, shutdowns and diagnostic codes

and perform troubleshooting.

• Log data to analyze load factor, run hours,

generator power, power factor, operating

temperatures, and many other parameters.

The module interfaces with Windows®-based PC

software, or your custom software. You can

regulate access to the control with three levels of

password security.

Customize and automate.

The Relay Driver Module offers nine discrete

outputs for custom control of your gen sets and

engine room by way of the Customer

Communication Module. Use relays to trigger a

horn or light for start annunciation, start an air

handler, activate the fuel transfer system, send a

start-up signal to the switchgear. Or countless

other possibilities.

Augment system protection.

Alarm Modules let you add more pre-alarms

and shutdowns – those generated by the

EMCP II/EMCP II+, or your own custom

configurations. Mount modules in the control

panel or remotely. Choose modules with eight or

16 alarm LEDs, or combine modules in

prepackaged panels. All alarm modules meet

or exceed National Fire Protection Association

(NFPA) standards.

Enhance remote monitoring.

The Customer Interface Module provides relay

contacts to communicate up to nine fault or alarm

conditions from the EMCP II or EMCP II+ to a

remote monitoring location.

The Cat communication module seamlessly merges your

Cat gen set into your building and operating system.
