Auto sensing features
Automatic voltage detection. The equipment determines the output level (HTL/TTL) according to input voltage. From 4.5Vdc to 10Vdc
output will remain in TTL, from 11Vdc to 30Vdc output level will be maintained in HTL as long as the device is programmed for HTL output.
Automatic overload detection in the encoder driver. In the event of a short circuit or overload in any of the outputs, the device will switch
to TTL until the error is remedied. The encoder's LED with blink red and the graphic interface will display the relevant red indicator, registering
the error, without interrupting the normal function of the device.
Automatic Driver/PLC input impedance detection. When the encoder is programmed for HTL outputs, if a driver/PLC with TTL inputs
(120O x Channel) is connected, the encoder will switch outputs to TTL automatically.
Automatic humidity detection inside the encoder. Water, humidity and condensation alarms. The encoder's LED with blink red and the
graphic interface will display the relevant red indicator, registering the error, without interrupting the normal function of the device.
Optical error detection. Any dysfunction in the OptoAsic illumination or breakage of any of the optical elements is automatically detected
and is described by the graphical interface alarms, logging the error, without interrupting the normal operation of the encoder.
