• All operating data and functions can be set: Operation

see section 4 and 5.7 function 1.06 and 1.07.

• The pulse and status outputs 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

• Digital pulse division, interpulse period is non-uniform. Therefore, if frequency meters or

cycle counters are connected, allow for minimum counting interval:

2.1 Current output I

•

The current output is galvanically isolated from all input and output circuits.

•

Factory-set data and functions can be noted down in Sect. 5.16.

Please also refer to Sect. 3.2 “Factory settings”.

•

Typical current output

•

All operating data and functions can be set: Operation see section 4 and 5.6 fuction 1.05.

•

The current output can also be used as an internal voltage source for the outputs.

int

= 15 V DC I = 23 mA when operated without receiver instruments at the current output

I = 3 mA when operated with receiver instruments at the current output
