Changing the tones by external control

It is possible to obtain up to three additional tone types using the following electrical controls for applications
that require additional tones in addition to the base tone.
The desired base tone (♪, see tone type table in the Annex) is always set first with the tone selector switch S3
on the driver board. The corresponding additional tones (C1, C2, C1+C2) can be found in the "Control of
tones" table in the Annex.

Stage selection via control input (TAS), AC and DC versions

Note: Always apply the supply voltage together with the control inputs.
Caution: If the control voltage is higher than the supply voltage or the supply voltage is not present at all, the
operating current will be supplied via the control inputs. A corresponding carrying capacity has to then be en-
sured.
Negative control: (Factory setting)
Switch setting should be as follows:
➢ Switch S2: with reverse polarity protection, (with rectifier)
➢ Switch S1: to „–"
