8.2.1 Lock-down of the setpoint change
The operator interfaces of the BT 300 series can be locked using a jumper 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 setting A:
with setpoint change
Jumper setting B:
without setpoint change
The operator interfaces are set to the jumper position A (with setpoint change) at the factory.
If operator interfaces are mounted in areas accessible to the public, i.e. on serving counters for the
sales personnel, the jumper position
B
should be selected (without setpoint change).
