Stage Selection By Supply Via Control Input (Tav) - All Dc Versions - Pfannenberg PA 1 Manual

en
Note: Always apply the supply voltage together with the control inputs.
24 V AC/ 115/ 230 V AC: Apply phase "L" of the supply voltage to the control inputs C1 / C2.
Only 48 V AC: Apply "N" of the supply voltage to the control inputs C1 / C2.
Operating voltage
7.1.2 Stage selection by supply via control input (TAV) – all DC versions
Note: Only applicable to DC version!
The sounder can be supplied with operating voltage via the control inputs C1 / C2 on the connection board.
Supply and stage selection therefore take place simultaneously.
Switch setting should be as follows:
 S1A to
(diode not bridged)
 Changeover switch S1B to "+"
 Connect the negative terminal on the connection board.
 Connect the positive terminal on the connection board. The basic tone (♪) is generated.
 Connection of the positive voltage to C1 on the connection board generates tone C1.
 Connection of the positive voltage to C2 on the connection board generates tone C2.
 Simultaneous connection of the positive voltage to C1 and C2 on the connection board generates tone
"C1+C2".
