Keyboard operating can be locked by pro-
gramming the “Loc” parameter (see folder
with “diS” table). If the keyboard is locked
you can only access the Programming
MENU (see) Functions CANNOT be activat-
ed with buttons (to silence alarms, for
example).
TELEVIS SYSTEM (LX MODELS ONLY)
The Televis remote control systems can be
connected using the TTL serial port.
The TTL- RS 485 interface module must be
used:
• 130 or 150 BUS ADAPTER.
• 350 BUS ADAPTER for EM300(LX) with
V/I. Pt100/TC input.
To configure the instrument to do this, you
need to access the folder with the “Add”
label and use the “dEA” and “FAA” para-
meters.
