In case of bidirectional values, option on request, exported energy variables can be selected for digital
output pulse weight setup.
The multiplying factor ([ ] none, [k] kilo, [M] mega) and the decimal point depend on the selected CT and
PT value. The pulse length is 100 ms. Set the values following section 8.5.2.
Example:
Selected values: Variable = Wh; pulse = 1000; multiplier = [k];
Digital output: 1kWh / pulse (active energy)
For further information on how to determine the pulse value, see section 8.5.3.
Firmware release [rEL]
This page shows the firmware release of the instrument.
Exit from SETUP [SAVE]
This page allows to quit the SETUP mode and to save the modifications.
There are three possibilities:
NO: quit without saving the modifications•
YES: quit saving the modifications•
CONT: remain in SETUP mode•
Set the value following section 8.5.2.
8.5.2 Modifying the values
The following procedure must be followed to set/modify the SETUP values.
From any SETUP page:
Press 1. SHIFT key to enable the modification. The value or the first digit will start to flash.
Press 2. UP key until the appropriate value is displayed.
Confirm the choice with 3. SHIFT key. The value or the digit stops flashing.
Repeat point 2 and 3 for all the values/digits.4.
8.5.3 Considerations on the pulse value calculation
The maximum pulse re-emission rate is 1 pulse/sec (3600 pulse/h).
The minimum value assignable to the pulse to prevent the overlapping is:
e
min
= P
max
/ 3600
P
max
is the maximum power on the measuring point controlled by the meter. The pulse value (e
min
) is
expressed in Wh, varh or VAh depending on the selected variable (P, Q or S).
Example 1
P
max
= 5MW
e
min
= 5000000/3600 = 1389 Wh/pulse (1.389 kW/p)
Example 2
P
max
= 800kW
e
min
= 800000/3600 = 222 Wh/pulse (0.222 kWh/p)
The result can be rounded off to a higher value for an easier calculation or totalization of the energy
consumption.
For example no. 1 it is possible to select 1.5 or 2 or 10 kWh/p.
For example no. 2 it is possible to select 0.5 or 1 kWh/p.
The pulse emission frequency will be proportionally lower.
Higher pulse weight = lower emission frequency.
