Emergency operation 

 
This operation mode is only to be used by trained people such as installers and service 
men. This emergency operation allows the platform to be used even if safety circuits are cut 
and emergency switches are inactive. 

 
Important: It is necessary that after the unit has been repaired the emergency 
operation mode will be disabled! 

 
To activate the emergency operation mode it is necessary to change the Jumper J1 on the 
drive unit control to the emergency drive position. 

 
Jumper J1 

This jumper controls the operation modus. The following 2 jumper positions are possible. 
Please note that no other than these 2 positions can be active, otherwise the board can be 
damaged. 
 

Standard operation 

Emergency operation 

 

 

 
If the jumper J1 was correctly changed then the LD23 should be on. If this is on the platform 
can be moved. But the drive commands can only be given from the external control (radio 
or hard wired). At the same time as a drive command is given the button S1 has to be 
pressed. Both buttons have to be pressed at the same time in order to improve the security 
during this operation mode. On the display the error 113 will be shown when the platform 
control buttons are pressed. 

 
Important: No security switches are active! The lift will continue driving as long as a 
drive command and S1 are pressed simultaneously.
