Short-circuit proof outputs yes 1) The encoder can be set to zero at any position by means of a HIGH signal on
the SET input. Other preset values can be factory-programmed.
CE compliant acc. to EMC guideline 2004/108/EC The SET input has a signal delay time of approximately 1 ms. Once the SET
ATEX guideline 94/9/EC function has been triggered, the encoder requires an internal processing time
RoHS guideline 2011/65/EU of approximately 15 ms before the new position data can be read.
DIR input Status output

The reverse function can also be factory-programmed. resistor 22 kOhm
If DIR is reversed when the device is already switched on, this will be Permissible load max. 20 mA
