1. Turning the key from position ´0´ to position ´I´ supplies the motor with power.
2. To lift press the function button and the UP button simultaneously.
3. To lower press the function button and the DOWN button simultaneously.
4. Turning the key from position ´I´ to position ´0´ immediately interrupts the power supply of the
motor and stops every movement (emergency stop function).
5. At power failure the lift can be lowered using compressed air.
6. If the status-LED (light emitting diode) burns ´green´ then the lift is ready for operation. A ´red´
LED indicates an error.
7. At lifts with additional wheel-free system a second LED as well as the printed symbol shows the
function mode PLATFORM or WHEEL-FREE. To switch between the two modes you have to
double-click on the function button. Double-click to the UP-button switches on the lighting. Double-
click to the DOWN-button switches off the lighting.

A regular yearly check by an expert is laid down for the lift. We recommend the carrying out of this
check together with a maintenance of an ROTARY-authorised service-technician.
You will find some tips for the carrying out of this yearly check and maintenance at chapter 5.
Necessary repairs can be carried out against separate charge.

The analogous multiplexer IC on the Piggy Board does not find the pull-
up resistor. Either Piggy Board is not working or CPU is damaged.
Exchange first Piggy Board then try another Control Board.

There was a reset initiated by the watchdog, checking if the controller
firmware is still alive. This error may happen if the keyswitch is quickly
reswitched on. The supply voltage had no time to go down enough. If
this error happens during normal operations, the CPU or at least the
firmware in it is damaged. Exchange the Control Board.
18 EDODQFHVDIHW\FLUFXLWRQ The redundant balance safety circuit noticed a large difference
between the left and right cylinders. If it is no „electronic balance“ type
of car lift, check if the socket for the balance circuit on the Piggy Back
Board is empty. Next enter the Servicemen and check the values of
the cylinder heights. Maybe the potentiometer has to be readjusted.

The analogous +5Volt supply is not ok. Check for a short circuit on the
potentiometer cables. Next exchange the Piggy Board. If error persists,
exchange Control Board.

22 XSZDUGVVSHHGWRRORZ The upwards speed was too low. Check the limit programmed in the
configuration EEPROM. If correct, the car lift may be overloaded, the
hydraulic pressure not sufficient (due to a damage) or the car lift was
mechanically blocked by an obstacle.

The limit for the downwards speed was exceeded. Call the service
