Changing sensing distance "x"
If no circuit state change occurs at the voltage encoder (LED display) with rotating
shaft of the adapter shaft operating with sensing distance x = 1 mm, the sensing dis-
tance can be changed as follows:
1. With
constantly lit LED
[4] of the voltage encoder, turn the voltage encoder a half
turn
counterclockwise
at a time and check its function.
2. It the
LED is not lit
[4], turn the voltage encoder
clockwise
by 90 degrees but no
more than one time.
CAUTION
A collision with the slotted screw heads may destroy the voltage encoder.
Possible damage to property.
•
Do not turn in the voltage encoder by more than half a turn
3. If a circuit change still does not occur, check the voltage supply of the voltage en-
coder using the evaluation electronics (with WEXA/WEX design).
