Wiring

Type

• 3PH3W
• 3PH4W
• 1PH2W L-N
• 1PH2W L-L
• 1PH3W L-L-N
• 1PH4W Multi L-N

Select the power system type the meter is wired to.

VT

• Direct-NoVT
• Wye (3VTs)
• Delta (2VTs)

Select how many voltage transformers (VT) are connected to the electrical power system.

CT

• 3CTs on I1, I2, I3
• 1 CT on I1
• 2 CTs on I1, I3

Define how many current transformers (CT) are connected to the meter and which terminals they are connected to.

CT & VT Ratio

CT Secondary

• 1
• 5

Select the size of the CT secondary, in Amps.

CT Primary

1 to 32767

Enter the size of the CT primary, in Amps.

VT Secondary

• 100
• 110
• 115
• 120

Select the size of the VT secondary, in Volts.

VT Primary

1 to 1000000

Enter the size of the VT primary, in Volts.

Frequency

Frequency

• 50
• 60

Select the frequency of the electrical power system, in Hz.

Date

Date

DD-MMM-YYYY

Set the current date using the specified format.

Time

Time

hh:mm

Set the time using the 24-hour format.

Multi Tariffs

Control Mode

• Disable
• by Communication
• by Digital Input
• by Internal Clock

Select the tariff control mode:

• Disable: the Multi Tariff function is disabled.

• by Communication: the active tariff is control by communications. See the chapter for the applicable protocol for more information.

• by Digital Input: the digital input is associated with the Multi Tariff function. A signal to the digital input changes the active tariff.

• by Internal Clock: the device clock controls the active tariff. If you set the Control Mode to by Internal Clock, you must also configure the schedule. Set the time when each tariff period starts, using the 24 hour clock format (00:00 to 23:59). The start time of the next tariff is the end time of the current tariff. For example, T2 start equals the end of T1.

Overload Alarm

Alarm

• Disable
• Enable

Select whether or not the Overload Alarm is enabled:

• Disable: the alarm is disabled.

• Enable: the alarm is enabled. If you enabled the Overload Alarm, you must also configure the Pick Up Value in kW from 1 - 9999999.

Digital Output
(iEM3235 / iEM3255 / iEM3265 )

DO Function

• Disable
• Alarm
• Pulse (kWh)
• Pulse (kVARh)

Select how the digital output functions:

• Disable: the digital output is disabled.

• Alarm: the digital output is associated with the overload alarm. In the event of trigger, the digital output remains in the ON state until the alarm drop out point is crossed.

• Pulse (kWh): The digital output is associated with energy pulsing (active energy). When this mode is selected, you can select the energy parameter and set the Pulse Constant (imp/kWh) and the Pulse Width (ms).

• Pulse (kVARh): The digital output is associated with energy pulsing (reactive energy). When this mode is selected, you can select the energy parameter and set the Pulse Constant (imp/kVARh) and the Pulse Width (ms).

Digital Input

DI Function

• Input Status
• Tariff Control
• Input Metering
• Partial Reset

Select how the digital input functions:

• Input status: the digital input records the status of the input, for example, OF, SD of a circuit breaker.

• Tariff Control: the digital input is associated with the Multi Tariff function. A signal to the digital input changes the active tariff.

• Input Metering: the digital input is associated with input metering. The meter counts and records the number of incoming pulses. If you set the DI Function to Input Metering, you must also configure In. Pulse Constant.

• Partial Reset: a signal to the digital input initiates a partial reset.

LED Energy Pulse

Energy

• kWh
• kVARh

Set the active energy and reactive energy.
