Description
SONIC DIGITAL HS MD/MFD
20
D-SUB PIN 7
This is the output of an internal relay (root to PIN 5/9). This relay reports generator
malfunctions. This means that if the generator is switched on and the power output
does not correspond to the set level for whatever reason, this relay will be activated.
INFO
Factory default setting:
Closed in the event of a malfunction.
The polarity can be changed via the I/O POLARITIES menu item
in the SETTINGS menu (ERROR DETECT). An external voltage
connected to HF-DA ERROR can, of course, also be routed through
here (max. 24V / 100mA).
Please refer to the operating manual provided with the software
DSUB PIN 8
Non-inverting input for RS485 communication.
DSUB PIN 10
Inverting input for RS485 communication.
D-SUB PIN 11
Open collector output:
Signal HIGH When limit values are activated:
the generator operates outside the limit values.
Signal LOW
When limit values are activated:
the generator operates within the limit values.
D-SUB PIN 12
When the internal fan controlled by the intelligent fan control system is running, a
voltage of 12V is available at this output. The voltage is for monitoring the function
of this fan.
D-SUB PIN 13
Switching on the generator (ultrasound ON) by applying a voltage of 10V - 24V
between PIN 13 and GND (PIN 4 or PIN 15).
D-SUB PIN 14
Switching on the generator (ultrasound ON) with a relay contact or switch by
connecting PIN 14 of the D-SUB socket to GND (PIN 4 or PIN 15).
D-SUB PIN 4, 15
The GND signal is available at the two PINs of the D-SUB socket.
GND is the common reference point for all input/output signals.
NOTE
§
For control purposes,
always use GND (PIN 4 or 15)!
Otherwise, malfunctions will occur.
