7.6 Analogue output function module

The module has 2 passive analogue output connections which are freely
programmable using the IZAR@SET software. On the terminal strip, the
electrically isolated outputs "1" and "2" are marked and the polarity is
indicated ("+" and "–").
ƒ
passive, external power
supply: 10 ... 30 VDC
ƒ
Current loop 4 ... 20 mA
whereby 4 mA = 0 value;
20 mA = programmed
max. value
ƒ
Overload up to 20.5 mA,
then residual current
ƒ
The module displays errors
with 3.5 mA or 22.6 mA
(programmable)
ƒ
Output values: power, flow, temperatures
The module is connected with the meter electronics by means of
a ribbon cable. The separate plug connector on module slot 2 is
necessary for the perfect functioning of the analogue outputs.

7.7 Test output

The internally located test output is intended for testing laboratories.
The manufacturer supplies two special cables:
1. Volume testing pulse
2. Energy testing pulse
Please refer to the inspection and testing manual for further specifications
(pulse weighting, pulse duration/pause, pulse frequency).
Ensure that the temperature sensors (measurement resistances)
remain in contact without interruption during energy verification.
