VEGAMET 625 • Double channel HART

•
Overfill protection: Relay is switched off when the max. level is
exceeded (safe currentless condition), relay is switched on again
when the level falls below the min. level (switch-on point < switch-
off point)
•
Dry run protection: Relay is switched off when the level falls
below the min. level (safe currentless condition), relay is switched
on again when the max. level is exceeded (switch-on point >
switch-off point)
Additional modes such as "Switching window", "Flow" and "Tenden-
cy" can be only adjusted via PACTware and DTM.
Select the requested mode and save with [OK]. By pushing [->], you
reach the next menu item.
1. Now enter the reference value to which the relay switching points
relate. By pushing [->], you reach the next menu item.
2. Enter now the switching points for switching the relay on and off.
The parameter to which they refer can also be selected.
In the following window the reaction of the relay in case of failure can
be determined. Here you can define whether, in case of failure, the
switching condition of the relay remains unchanged or the relay is
switched off.
The current output is used to transfer the measured value to a higher
ranking system, for example to a PLC, a control system or a meas-
ured value indication. This is an active output, i.e. a current is provided
actively. The processing unit must hence have a passive current input.
The characteristics of the current outputs can be set to 0 … 20 mA,
4 … 20 mA or inverted. The reaction in case of failure can be also
adapted to the requirements. The parameter to which they refer can
also be selected.
