2.2 Pulse output P
•
The pulse output is galvanically isolated from the current output and all input circuits.
•
Setting data and functions can note down in Section 3.3.
Please also refer to Sect. 3.2 Factory settings.

•
All operating data and functions can be set, see Sect. 4 and 5.7, Fct. 1.06 for operator control
•
The pulse output can be operated in the active or passive mode.
•
Active mode: The current output is the internal voltage source,
connection of electronic totalizers (EC)
•
Passive mode: External DC or AC voltage source required,
connection of electronic (EC) or electromechanical (EMC) totalizers
Please note:
A fixed pulse width (0.01 – 1s) must be set for operation with EMC
totalizer. Only then is an optocoupler active for higher output currents.
•
Digital pulse division, interpulse period is non-uniform. Therefore, if frequency meters or
•
cycle counters are connected, allow for minimum counting interval:
