Terminating
resistor
Yes, a
120 Ohm terminating resistor
must
be installed at
the end of the line (at the last temperature display).
No.
Simply connect,
Plug and Play
Required
accessories
1x 6-pole COMBICON connector and
4x wire end sleeves
1x terminating resistor 120 Ohm
if necessary, 1x terminal block for looping through the
shield. Alternative: Cable ties
RJ45 distributor including connection cable 0.5 m
(KGLVERTBT1),

Cable length
Max. 30 m:
1..4x VDD 500
Note:
BT 300 cannot be used simultaneously for system
reasons!
Max. 480 m:
1x BT 30
and
1x BT 300
Max. 210 m:
2x BT 30
and
1x BT 300
Max. 130 m:
3x BT 30,

Configurability of
the temperature
display
Only
via system centre (in the machine room) and CAN
bus,
no
standalone local configuration possible.
Even after the VDD scan (displays were found on the
Modbus), no subsequent assignment of sensors is
possible via BT 300,
always only via the system
centre!
Via system centre and CAN bus, standalone local
configuration easily possible with BT 300.
Addressing and
preconfiguration
Only
possible in connected state,
must
be connected to
controller, sensors can only be assigned via terminal
mode via the system centre.
Preconfiguration is not possible
- only in connected
state (connection to case controller) in the system!
Coding is possible by cutting the wire loops.
A
preconfiguration without current is possible at any
time
,
e.g. by the switch cabinet builder.
Possible problems
with address
allocation/
VDD Scan
Possible address conflict!
But ONLY if the last two digits of the serial numbers are
identical. Installer must ensure that this constellation does
not occur.
None
.
With the same coding of the wire bridges, e.g. of two BT
30, they show the same temperature.
Compatibility with
controllers
Only UA 4xx E
with
9-pole DIP switch
and
Version
V3.20 or higher
All controller types
from
UA 300 x
to
UA 400 x
are
supported.
