Setting limits

Procedure: Determining the switch status of the slotted initiators
You will require a suitable display device to determine the switch status. For example, use the
initiator tester type 2 / Ex from Pepperl + Fuchs.
1. Connect the display device to the following terminals of the Inductive Limit Switches (ILS):
– 41 and 42
– 51 and 52
2. Read the switch status of slotted initiators.
Procedure: Setting the limits L1 and L2
The consecutive numbers in the following text refer to the figure above in this section. Proceed
as follows to set the limits:
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disk
changes. Set a high-low or a low-high switchover as follows:
– Rotate the actuating disc
3. Move the actuator to the second desired mechanical position.
4. Adjust the lower actuating disk
changes. Set a high-low or a low-high switchover as follows:
– Rotate the actuating disc
