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.
7.
An insulating cover is provided over the mechanical limit switch module. Place the
insulating cover to one side under the motherboard seat on the container wall. The
recesses of the insulating cover must fit in the corresponding webs of the container wall.
8.
Place the insulating cover on the mechanical limit switch module by bending the
container walls carefully.
9.
Engage the motherboard into the four brackets.
10.
Fix the motherboard using both the fixing screws.
11.
Reestablish all electrical connections between the motherboard and the optional
modules. Connect the motherboard and the optional modules to the ribbon cables
provided. Connect the motherboard and the potentiometer to the potentiometer cable.
