3. Configuration

By using jumpers it is possible to set on what kind of event should departure switch react by closing or opening its contacts. The departure switch can react to three different events: dep. switch on/off from the SWITCH 1, dep. switch on/off from the SWITCH 2 and pick up/hang up the telephone line (means beginning and end of the call).

The dep. switch contacts are available both normally open (between clips NO and C) as well as normally closed (between clips C and NC). NC and NO in this case refers to the contact state. see pic. above.

Example 1 – dep. switch operation by using password for SWITCH 2

Switching on and off is set to SWITCH 2. Dep. switch will close after receiving password for SWITCH 2 (parameter 821) and open after the switching time for SWITCH 2 (parameter 823) will elapse. If you set parameter 824 to non-zero value, will be also synchronized with SWITCH 1 (explained in the communicator manual).

Example 2 – dep. switch operation for unlimited time

Dep. switch closure is set to SWITCH 1, dep. switch opening to SWITCH 2. The dep. switch will close when it has received the password for SWITCH 1 and will remain closed until the communicator has received the password for SWITCH 2 and until the switching time of SWITCH 2 elapses (parameter 823, it is recommended to set this parameter as low as possible, which is 1s).

Example 3 – dep. switch closure for the duration of the call

Closure and opening is set to SPEAK. The dep. switch will close when the line is picked up and open when the line is hung up. For the duration of the call the dep. switch will be closed.
