25 If the motor Z of the actuator A begins to move, causing the rod A1 to protrude outside the body, this means
that the motor is operating correctly. Proceed to check operation of the micro switches X and Y.
Checking operation of the internal micro switches
You do not need to remove the protective cover to check operation of the micro
switches in the body of the actuator as they produce an audible sound when
actuated.
The following photographs show the inside of the actuator to give an idea of how the
micro switches work in the various situations.
26 Obtain a digital multimeter with a continuity measurement function, see photograph below.
27 Rotate the rod A1 by hand and check that the cam K on the rod is in the correct position (under the bottom X
or top Y micro switch) by listening for the mechanical click emitted by the micro switches when the actuator
button X1 - Y1 is pressed.
28 The six wires are connected to the two micro switches X and Y as shown in the diagram below.
