An operator interface in the BT 300 series is connected locally via the DISPLAY interface. Thereby, the
controller can be operated standalone as shown or also connected to the CAN bus.
The operation here largely corresponds to the possibilities as described for the system centre, the store
computer and the operator terminal, For details, see
.
Menus and operating screens, page 79
If no buttons are actuated, the display of the BT 300 x operator interface shows the name of the controller and
its position designation. The
button (
) must be tapped to return from the display of the operating
ENTER
status back to the Operation menu.
Device-specific limitations arise due to the smaller display (only 2 rows x 20 characters) and fewer
buttons as compared with the system centre, the store computer and operator terminal. Operation
with a system centre, store computer, operator terminal or the PC software LDSWin provides more
functional possibilities. Technical details about the operator interfaces can be found in their operating
manuals.
8.2.1 Locking of the setpoint change
The operator interfaces of the BT 300 series can be locked using a jumper (J) on the circuit board so that all
actual values, parameters, temperatures and statuses can be viewed, but so that it is no longer possible to
adjust the setpoints of the respective controller.

Jumper position B:
The operator interfaces are set to the jumper position A (with setpoint change) at the factory.

sales personnel, the jumper position should be selected (without setpoint change).
