Data Transmitter 795
SW ver. 830434
The following signals are available:
- internal flag 1-8
- digital input 1-8/12/16
- analogue limit HIGH 1-4
- analogue limit LOW 1-4
- 704 system error
- power failure
- 704 output 1-2
Only one call attemt will be made. In case the
same signal are selected as both start condition
and stop condition, the stop condition will be
when the digital signal goes OFF.
Use the arrow keys and confirm with ENTER.
11.4.3 Receivers telephone / ID number
Enter the telephone number / ID number of the
Data Transmitter to be interlocked.
Enter the ID number if radio modems are used.
If the receiver is another Data Transmitter which is
directly connected to the same multidrop line via
the RS485 port, the ID number of the Data Trans-
mitter preceeded with a minus. (The F key is used
to enter the minus character.)
Ex.: Data Transmitter ID 001 is supposed to
remote control Data Transmitter ID 003:
Enter the ID number "- 003" into Data
Transmitter 001.
If the receiver is another Data Transmitter which is
communicating via data radio, the Data Trans-
mitter's ID-nummer should be entered without a
preceeding minus.
11.4 Interlock active / inactive
Select if the previously chosen Data Transmitter
(substation) should be interlocked.
Use arrow keys and confirm with ENTER.
11.4.1 Start of interlock
Select the signal initiating an interlock on the
selected Data Transmitter (substation):
The following signals are available:
- internal flag 1-8
- digital input 1-8/12/16
- analogue limit HIGH 1-4
- analogue limit LOW 1-4
- 704 system error
- power failure
- 704 output 1-2
As long as the signal is ON, all calls will take
place in the interlock interval previously chosen.
If the interlock interval is set to 10 minutes or
more, the remote controlled output should be
configured as time controlled with an ON-time set
to more than 10 minutes (e.g. 15 minutes) to
avoid a situation where the remote output is ON
constantly caused by a communications error.
(E.g. a broken telephone cable.) In this way it is
ensured, that the output is switched OFF, if
communications fail.
On error-free communication the ON-timer on the
remote controlled output will be initialized on
every call, and with that the output will stay ON as
long as the controlling signal is active.
Use arrow keys and confirm with ENTER.
11.4.2 Stop interlock
Select the digital signal that - when switched OFF
- will cause the Data Transmitter to call the other
Data Transmitter and set an output OFF:
