The mechanical limit switch module consists of:
●
One binary output to display a collective fault message. Compare with the device features
of the alarm unit.
●
Two switches to report two mechanically adjustable limits. Both these switches are
electrically independent from the remaining electronic unit.
Installation
Proceed as follows to install the mechanical limit switch module:
1.
Disconnect all electrical connections of the motherboard.
2.
Unlatch both the fixing screws of the motherboard.
3.
Disengage the motherboard 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 unit in the printed circuit board of the module
rack approximately 3 mm towards right.
6.
Screw in the special screw through the mechanical limit switch module into the positioner
shaft. Tighten the special screw with a torque of 2 Nm.
NOTICE
A pin in the actuating disc bearing is pressed. Align this pin before it touches the special
screw. You must rotate the actuating disc bearing and the special screw simultaneously
so that the pin is inserted into the special screw.
