6.4.2.2 External Speaker
An external speaker can be connected to the symmetric audio exit PIN 7 and PIN 2. The level of
the audio signal is controlled in the “adjust volume” submenu (see 5.2.5.).
Permitted impedance of speaker: 4 ... 600 Ohm
Max. voltage (PIN 7 – PIN 2): 10 V
ss
Max. permitted power: 1,5 W
6.4.2.3 Alarm Contact
The alarm contact is connected to (see 6.2.1.5.5.1) PIN 3 and 4. It is a mechanic relay with
floating contacts.
Current: max. 1A
Max. voltage: 50 V (DC)
(values for ohmic (resistive) load)
Controlling: see 6.2.1.5.5.1
6.4.2.4 Extern Input
Contact PIN 8 is a sensory input for digital logic levels. The contact is connected to +5V by
means of a PULL-UP-resistor (10 k). In order to activate the SBS-function (as described in
6.2.1.5.5.2) the input has to be connected to GND (PIN 1) by the means of an external
operating contact.
6.4.2.5 Analog Test
PIN 6 is carrying a test signal, serving for trouble-shooting in the case of service.
During operation of the bearing system this contact is not to be connected.
6.4.3 Interface Connector
The bearing system RT-300 has different interfaces for data exchange.
- RS-232
- RS-422
- RS-485
These interfaces are connected to socket ”Interface Connector“ (see Fig. 2 ).
ATTENTION
The audio exit is connected to a push-pull amplifier. Therefore none of the audio
signals is to be connected to ground. Grounding audio signals will damage the
device.
