CE compliant acc. to EMC guideline 2004/108/EC
ATEX guideline 94/9/EC The encoder can be set to zero at any position by means of a HIGH signal on
RoHS guideline 2011/65/EU the SET input. Other preset values can be factory-programmed.
The SET input has a signal delay time of approximately 1 ms. Once the SET
function has been triggered, the encoder requires an internal processing time
DIR input of approximately 15 ms before the new position data can be read.
A HIGH signal switches the direction of rotation from the default CW to CCW.
The reverse function can also be factory-programmed. Status output
If DIR is reversed when the device is already switched on, this will be Output driver open collector, internal pull-up
interpreted as an error. The status output switches to LOW. resistor 22 kOhm
Permissible load max. 20 mA
Power-ON time Signal level HIGH +V
LOW < 1 V
After Power-ON, the device requires a time of approximately 150 ms before
valid data can be read. Active at LOW
The status output serves to display various alarm or error messages. The status
output is HIGH (open collector with internal pull-up 22 kOhm) in normal operation.

1) Short-circuit with 0 V or output, only one channel at a time, power supply correctly applied.
