Operating instructions – control of new vehicle lifts:
DATE 16.04.02
Status : Version 1
Introduction:
The control of the lift is a micro-processor controlled system.
Next to the actual selection of two keys (UP/DOWN) and the activating of two light diodes and the motors,
a large number of system tests is carried out during operation, which guarantee the perfect functioning of all
important system components.
Operating panel:
The control panel has the following operating / display elements:
One key “UP”, one key “DOWN”, 1 light diode and one signal initiator.
In addition, a key is attached to the control platform which makes a single drive action of the stage possible
in emergency.
General information:
After switching on, the control unit is in the so-called stand-by mode:
This mode is indicated by the colour orange of the light diode.
Before the actual raising or lowering process the respective key must be pressed for safety reasons
(protection against unauthorised operation). -> The LED changes its colour from orange to green, indicating
that the lift is ready.
If the key is pressed again, the movement of the two lifting carriages is acti vated.
If the key has not been pressed for approx. 30 seconds, the control of the lift changes into the stand-by
mode and the colour of the LED changes from green to orange.
During operation (travel) the following standard situations can occur:
1.)
The lifting carriages reach their end position -> green LED is blinking
2.)
The entrance for the external upper or lowe r end switch becomes active: -> Green LED is blinking.
3.)
One or both motors are overheating. -> Error code 11 is shown.
An error code is displayed as follows:
Acoustically with a defined tone signal and phase timing, for example error 11:
The “tens” are shown first by a long tone signal and the “units” follow as a short tone signal.
Before the repeat of the error code there is a pause.
Parallel to the acoustic signal the error code is also displayed visually on the red LED (its length is
identical with the acoustic signal).
Error code 11 is shown as follows: 1 x long tone, 1 x short tone, 1 x pause
This sequence is repeated until the motors have cooled down.
Error 11 is the only error where the control switches back into stand-by position (ready).
