Test PWM subitem
Test of the pulse width modulation. Set the electrical voltage in proportion
to the force exerted by the electrical actuator (100 % corresponds to 24 V).
The modulation is applied in 2 periods (t1 and t2) and must be adjusted in
percent. The BOOST function effects a voltage overshoot in period (t1).
To check the power outputs of the pulse width modulation:
1. Use the
/ buttons in the PWM field to choose the element that you
wish to test.
Fig. 94: Test PWM subitem
2. Press the OK button to confirm the selection.
The
Value display toggles between ON and OFF every time the OK
button is pressed.
3. Observe the selected element and check if a press on OK actually
triggers it.
Important
The values indicated in the % field merely provide a reference point as to
the range within which the tension may increase or decrease.
Test Input subitem
Test of the inputs according to the interconnection diagram.
To perform the test steps:
1. Select the desired element with the
/ buttons in the Input field.
Fig. 95: Test Input subitem
2. Confirm the selected element (e.g. button, knee lever, etc.).
3. Observe the display on the control panel.
If the element is functional, the display switches between
ON and OFF
under
Value.
