Z21 ® multi LOOP
Analog reverse loop
The analog reverse loop reverses the main track polarity instead of the loop polarity. For an automatic
operation however a few details have to be observed. A seperate power supply is required to power the
module (14 – 24 V DC). A minimum driving voltage of 5 Volts is required to ensure a safe sensor operation.
Additional diodes must not be used. The reverse loop must always be operated in the same direction.
Caution: If you use the Z21
deactivated.
