Setting of the terminal resistor
As described in Chapter 02, the terminal resistor in ABB-
Welcome audio only systems is always switched to "OFF".
For video systems, the terminal resistors are to be switched
to "ON" for the last devices of a branch and to "OFF" for all
others.
The terminal resistors are set via the switch "R/C" on all
indoor stations as well as video indoor distributors and
auxiliary power supplies.
Setting of the door opener or light switch
The setting is only made on the door/light switch actuator. It
shows the respective function of the device in the ABB-Wel-
come system. The sliding switch on the device is used
for setting.
Setting of the door opener times and light times
This setting on the system controller and the door/light
switch actuator determines the operating period of the door
buzzer (from one to ten seconds). The light-on period can be
set between one second and five minutes.
A separate potentiometer for both is located on the system
controller. In case of the switch actuator the same potentiometer
is used for one of the two control values depending on the
position of the sliding switch.
