Interface signals
D-SUB PIN 1
A voltage of 15V is available at this output. This voltage can only handle a maximum
current of 100mA and can, for example, be used to emit a voltage for the HF-DA
and/or ERROR functions.
D-SUB PIN 2
A voltage proportional to the power output of between 0V and 10V (i.e. 0% - 100%
power output) is available at this output. Reference point = GND.
D-SUB PIN 3
By applying a voltage of between 5V and 10V, the amplitude of the generator can
be set to between 50% and 100% of the nominal amplitude.
To do this, go to the SETTINGS menu (password 6354) and select the EXTERNAL
VOLTAGE setting under the PWR.SRC menu item. The reference point is GND.
D-SUB PIN 5/9
Shared output/input for the internal relays HF-DA and ERROR.
(These PINs are connected internally.)
D-SUB PIN 6
If the ultrasonic generator has been switched on
via either of the FS-24V or FS-GND signals
or the ON/OFF button of the MCU
or via the TEST button on the front panel
and is emitting HF voltage (i.e. there is no malfunction), an internal floating relay
contact is closed (between PIN 6 and PIN 5/9).
The root of this relay contact leads through to PIN 5 and PIN 9 on the D-SUB sock-
et. This relay contact can now be scanned by an external control system. A voltage
applied to PIN 5/9 can, of course, also be routed through (max. 24V/100mA).
INFO
Factory default setting:
Contact closed when generator emits HF voltage.
It is particularly useful to scan this contact when a timer operation is
being carried out and the generator switches off automatically once
the time has elapsed (factory default setting RF detect H). The con-
tact can also be switched to reverse polarity in the SETTINGS menu.
