2 DESCRIPTION

Fig. 2-1 Functional diagram of a Parallel System RPA in IEMi Operation Mode

GE Digital Energy offers the IEMi - Intelligent Energy Management integrated option to optimize
energy cost while maintaining the highest possible reliability for Parallel Redundant Uninterruptible
Power Supply units (max 6).

For Parallel System installations, secured with Redundant Parallel Architecture™ (RPA™), IEMi Operation
Mode saves energy by dynamically utilizing the UPS units as needed to meet the required load without
compromising the power quality to the critical load.

The software will calculate the number of UPS units which are needed for load supply based on
following:

• Redundancy (N+1 or N+2) • System Load • Rectifier status

• Inverter operating time • IEMi Operation Mode programming

Particularly, the UPS control logic determines the minimal set of UPSs required to maintain a reliable
supply to the critical load.
Then, an efficiency optimization algorithm determines the best UPS configuration in order to maintain
the running UPS in their highest efficiency operating region.
Energy losses are reduced by switching the inverter section of one or more units to a stand-by state.
The critical load is fed by the remaining units operating in double-conversion.
As load increases, other units are gradually switched on-line in order to maintain the required
redundancy level.

The IEMi - Intelligent Energy Management integrated option is only available on parallel installations.
It is clear that in order to enjoy the benefits of IEMi operation a system programmed for N+1
redundancy requires a parallel installation of at least three UPSs, while four UPSs are required for N+2
redundancy.

IEMi - Intelligent Energy Management integrated is an option, and it is available only if introduced at the
factory, or if introduced in field installations by a GE GLOBAL SERVICES FIELD ENGINEER.

Benefits of IEMi - Intelligent Energy Management integrated include:

• Higher efficiency (reduced losses) in low-load conditions (efficiency optimization)

• No compromise on power quality (double-conversion operation)

• No compromise on system reliability (redundant operation)

the redundancy level can only be updated when IEMi Operation Mode is disabled (Enabled: N).

Note:

In order to enjoy the benefits of IEMi Operation Mode operation a system programmed for N+1
redundancy requires a parallel installation of at least three UPSs, while four UPSs are required for
N+2 redundancy. The IEMi Operation Mode must be available on all units in a Parallel System.

If IEMi Operation Mode is currently disabled (N) and Q1 is closed, when programming it to
enable (Y) the selected configuration will automatically be propagated to all units in the
Parallel System.
If IEMi Operation Mode is currently enabled (Y) and Q1 is closed, when programming it to
disable (N) all stand-by inverters in the system will be switched on-line.

When programming IEMi Operation Mode for scheduled activation, IEMi must be left inactive for at least 1 minute
the week (otherwise, IEMi Operation Mode cannot be enabled).
This configuration forces a weekly test of all Inverters in the system.

DAY OF WEEK (d1 ÷ d7): Enabling time in function of weekdays

Note: the configuration of the activation schedule can only be

updated when IEMi Operation Mode is disabled (Enabled: N).

For the weekdays from d1 to d7 (Saturday to Friday) the edit mode

Events (alarms and messages)

Alarms and Messages are differently specified because the alarms are indicating an abnormal
functioning of the UPS (which are additionally signaled with the LED Alarm and acoustically with the
buzzer), while the messages indicate the various states of operation of the UPS (stored in the events list,
but not activating the LED alarm and the acoustical alarm).

Code Alarms Meaning

• The exact date and time when the event occurred.

• The number of the event, 255 being the most

recent event, and 0 the oldest.

• The standard GE code for the event and the

machine status word.

An explicit text description of the event.

4 OPERATION

When IEMi Operation Mode is active, the Inverter control and the selection of the feed path are done
autonomously by the UPS.
Therefore, when IEMi Operation Mode is enabled, Inverters may start/stop at any time.

IEMi START

Start of IEMi Mode Operation is based on the programming of dedicated Parameters and on the Load
being supplied by the UPS system (Q1 closed).
For IEMi Operation Mode to become active a manual Inverter start is required at start-up and after a
Load Off reset.
Additionally, activation is not inhibited from the dedicated input relay function (message 4606).
IEMi Mode Operation start is logged with the message 4604.

When IEMi Mode Operation is enabled, the “Inverter ON” and “Inverter OFF” commands from the Control
Panel, are disabled, since the Inverter control and the selection of the feed path are done autonomously
by the UPS.

During IEMi Mode Operation, the following events will force all Inverters on-line:

• Rectifier Utility/Mains failure.

• Bypass not available.

• Battery test.

• Transfer to Utility/Mains (overload or error detector).

• Connectivity bus failure.

IEMi STOP

Stop of IEMi Mode Operation is based on the programming of dedicated Parameters.
Additionally, activation can be inhibited from the dedicated input relay function.
When IEMi Mode Operation is stopped all inverters are switched on-line; this occurs in one of the
following conditions:

• IEMi Mode Operation is disabled.

The “Inverter ON” and “Inverter OFF” commands are enabled.

• End of programmed time:

The commands “Inverter ON” and “Inverter OFF” from the remain disabled.

• IEMi Mode Operation inhibited from the Input Relay (message 4607).

Only the commands “Inverter ON” and “Inverter OFF” from the Input Relays of the Customer Interface
(IM0005 or IM0171) are active.

5 SERVICE AND MAINTENANCE

WARNING !

All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.

All maintenance activities to be done with IEMi Operation Mode disabled.

Always disable IEMi Operation Mode before Service, Maintenance or Shut-down of a UPS unit.
Note: the disable command is not propagated if Q1 of the unit is open!

Maintenance bypass transition via digital I/O (CIC card).

• Inverter ON (I) / Inverter OFF (O) via digital input are disabled when IEMi Operation Mode is enabled.

• An ‘IEMi Control’ input function is available to deactivate IEMi Mode Operation (route digital input to

all units).

• Once IEMi Operation Mode is deactivated, Inv ON/OFF via digital I/O is operational.

Note: all inverters started when IEMi Mode Operation goes disabled / inactive.
