4�4�8�3�- Configuration of digital outputs
Digital outputs, in addition to being remotely managed, can be used as alarm elements, associated
with an electric variable by a maximum or minimum value, or can carry out the power impulse function
associated with any power consumption parameter (active or reactive).
The following input table is provided to programme them
Digital output 1
Modbus Address
Note: When a power variable is selected, the unit automatically recognises the power impulse function
and applies the w·h value of the first record. The pulse width value is in milliseconds
Example of alarm programming by maximum and minimum value with voltage VL1:
Programme a maximum value of 240 V and a minimum value of 200 V (the voltage value must be sent
multiplied by 10 (as shown in
Maximum value: 2400 (Decimal) → 00000960 (Hexadecimal)
Minimum value: 2000 (Decimal) → 000007D0 (Hexadecimal)
Delay: 10 (Decimal) → 000A (Hexadecimal)
Variable Number: 01 (Decimal) → 01 (Hex)
