4.7 Installing option modules
SIPART PS2 with and without HART
60 Operating Instructions, 10/2013, A5E00074631-11
Procedure: Setting the L1 and L2 limits
The serial numbers in the following text refer to the image in the chapter "Slot initiator alarm
module (Page 57)". With linear actuators, proceed as follows to set the limits:
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disk
④ 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
④ 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 51 and 52
changes. Set a high-low or a low-high switchover as follows:
– Rotate the actuating disc
⑤ 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 friction tempora
rily.
Move the actuator to and fro while simultaneously holding the actuating disks ④
and
⑤.
Mechanical limit switch module
Requirements
You are familiar with the procedure described in the chapter "Installing optional modules in
the standard and intrinsically safe version (Page 49)".
Procedure for installing the mechanical limit switch module
1. Disconnect all electrical connections of the basic electronics.
2. Loosen the two fixing screws of the basic electronics.
3. Disengage the basic electronics by carefully bending the four brackets.
4. Insert the mechanical limit switch module from the top up to the upper printed circuit
board guide of the module rack.
5. Slide the mechanical limit switch module in the printed circuit board of the module rack
approximately 3 mm towards right.
