Data Transmitter 795

11 Programming of interlock
With this function it will be possible for two Data
Transmitters to send command to each other.
E.g. one Data Transmitter can control a digital
output on another Data Transmitter.
Furthermore, if a Pump Controller 704 is
connected to a Data Transmitter, the output
relays on the Pump Controller 704 can be
controlled by another Data Transmitter 795.
11.1 Interlock of this station
This menu makes it possible to block remote
commands from other Data Transmitters
(substations).
Note, that interlock of a connected Pump
Controller 795 also will be blocked.
Use arrow keys and confirm with ENTER.
11.2 Interlock interval
This menu is used to set the interval for how often
other Data Transmitters should be dialed for
remote control.
The actual application and communication
method is decisive for setting the interlock inter-
val. As an example, in case communication are
taking place through a dialed line, it would be
expensive to exchange interlock commands
between two Data Transmitters every 5 minutes, if
it is about stopping a waste water pump in
connection with an overrun.
Use arrow keys and confirm with ENTER.
The setting will be valid for all Data Transmitters
(substations) that are being set to interlock in the
following menus.
