4.7 Installing option modules
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
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
4.7.5 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.
