13.Close the positioner as described in Closing the standard and and intrinsically safe version
(Page 53).
14.Set the limits L1 and L2 as described in Setting limits (Page 67).
4.5.5.3 Setting limits
Procedure: Setting the limits L1 and L2
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disk ④ manually until the output signal at terminals 51 and 52
changes. Set a high-low or a low-high switchover as follows:
– Rotate the actuating disc beyond the switching point until you reach the next switching
point.
3. Move the actuator to the second desired mechanical position.
4. Adjust the lower actuating disk ⑤ manually until the output signal at terminals 41 and 42
changes. Set a high-low or a low-high switchover as follows:
– Rotate the actuating disc beyond the switching point until you reach the next switching
point.
Note
Adjusting the actuating disk
The actuating disks ④ and ⑤ are relatively difficult to move. This design prevents their
unintentional movement during operation. You can achieve an easier and finer
adjustment by reducing stiction temporarily.
● Move the actuator to and fro while simultaneously holding the actuating disks ④
and ⑤.
