Instruction manual 973 SmartRadar LT Page 17
For remote transmission, the items
TA
and
TI
must be programmed and items
GT
and
TS
should be
checked. All these items reside under protection level 2. Proceed as follows:
Item Name Description
W2
= Protection level 2 Enter password 2. Default level 2 password: ENRAF2
TA
= Transmission address Two digits. Enter the desired transmission address. If gauges
are connected in parallel to the transmission line, each gauge
must have its unique transmission address. Mind the address
relation when connected to an 858 CIU:
CIU highway Transmission
address (
TA
)
TL 1 00 - 29
TL 2 30 - 59
TL 3 60 - 99
TI
= Tank identifier 6 Characters; program the tank name into
TI
(spaces are not
allowed). This name is used as subdirectory name in the Ensite
service tool to store information (log file, reflection diagram,
etc.) on the hard disk.
GT
= Gauge type 1 Character.
GT
represents the type of instrument.
For 973 SmartRadar LT,
GT
is B.
TS
= Transmission speed 4 Characters.
For Enraf field bus line
TS
is 1200 (default) or
TS
is 2400 baud.
For HART communication,
TS
remains on 1200 (default).
For RS-232C or RS-485 communication,
TS
is default 19K2
and can be set lower to: 9600, 4800, 2400 or 1200 baud.
EX
Exit Exit protection level. After the exit command, the 973
SmartRadar LT will perform a controlled software reset and all
changes made will be effective after start-up.
Example:
The SmartRadar LT on tank 102 will get transmission address 42. The gauge should be programmed
as follows:
Item (+setting) Description
W2=ENRAF2 <enter> Enter password 2 (ENRAF2 is default level 2 password)
TA=42 <enter> Transmission address equals to 42
TI=TNK102 <enter> Tank identifier.
GT <enter> Check whether the gauge type item is correct; if not, change it.
TS <enter> Check whether the transmission speed item is correct; if not,
change it.
EX <enter> Exit protection level.
As the transmission address (and perhaps also the baud rate) is changed, the service tool Ensite must be
adapted to the new conditions. That can be done as described earlier, or a ‘site scan’ can be made.
