3.10 Allocation pulse output 2
A total value can be assigned freely to the Pulse
output 2.
Available total values:
□
T Total consumption A-B or A+B
□
TA Total flow Volumeter A
□
TB Total flow Volumeter B
Note: This allocation is only effective with the
setting Function pulse output "independent", see
"3.07 Function pulse output", page 41.
Note : After the setting has been changed, the
electronic unit has to be restarted.
3.11 Scale pulse output 2
The scale of the pulse output is used to set the
pulse significance. Since the pulse values can
also be output in packets, we also recommend
using the pulse output only for total values. If the
value "0" is entered here, the pulse output is
deactivated, so that no pulses are output.
Note : Select the scale so that the limit frequency
of 250/125 Hz is not exceeded.
Note: This allocation is only effective with the
setting Function pulse output "independent", see
"3.07 Function pulse output", page 41.
Note : After the setting has been changed, the
electronic unit has to be restarted.
3.12 Pulse output pulse width
The pulse width of the pulse output can be set in
this menu.
Note: Increasing the pulse width always involves
a reduction is the maximum output frequency
(e.g. pulse width 200 ms – maximum frequency
2.5 Hz).
Note : After the setting has been changed, the
electronic unit has to be restarted.
3.13 Function relay 1
The relay function can be selected in this menu.
Note : Since the bypass function is safety-
relevant, we recommend the use as an NO
contact at Relay 1 (terminals 9+10) that triggers a
valve open when disconnected for the functions
Bypass 1–3.
Dropping of Relay 1 then corresponds to the
opening of the bypass valve.

Function Description
Off Relay output 1 is deactivated
Bypass 1 Differential measurement with 2
volumeters.
If one of the two counter does not
show a rate over the "Bypass limit
value " and the second one does
not follow within the "Delay
Bypass", the relay reverts to its
initial position and the alarm
"Bypass valve activated" is
generated. The alarm and Relay 1
and 2 can be reset in menu 1.10.
Bypass 2 Single-line measurement Volumeter
A.
When the value drops below the
limit, the relay reverts to its initial
position. After every expiry of the
repeat attempt period, the relay is
switched until the bypass time delay
has expired. If the limit value is
exceeded within this period, the
relay remains switched. Otherwise
it reverts to its initial position and
the repeat attempt period starts to
run again.
