SUPERVISION
The connection to supervisor systems is via the
RS-485
port and can use Televis or Modbus protocols.
The protocol to be used must be configured to ensure the proper function of Televis
In
and/or Televis
Out.
The parameters to be set
are in the “
Add
” folder, under the “Installer” parameters (see section entitled “Password”), as listed below.
N.B.
: 1) All communication parameters in the “Add” folder are not in the vectors.
2) A double terminal clip is provided as an RS485 connection accessory RS485
to connect two RS-485 in parallel.

LOADING DEFAULT APPLICATIONS
The procedure for loading one of the default applications is:
• At power-on of the device, keep the
key pressed: the label “
AP1
” will appear.
• Scroll through the various applications (“
AP1
”... “
AP8
”) using the
and
keys.
• Select the application you want using the
key (“
AP3
” in the example) or cancel the operation
by pressing the
key or by timeout.
• If the operation is successful, the display will show “
y
”, if not it will show “
n
”.
• After a few seconds the instrument will return to the main display.
RESET PROCEDURE
Televis
In
& Televis
Out
can be RESET and the default factory settings restored in a simple and user-friendly way.
This is done by simply reloading one of the basic applications (see “Loading default applications”).
You may need to
RESET
the instrument in circumstances in which the normal operation of the instrument is compromised or if you
decide to restore the instrument to its default configuration (e.g. Application “
AP1
” values).
IMPORTANT
!
This operation resets the instrument to its initial state, returning all the parameters to their default values.
This means that all changes made to operating parameters will be lost.
