Before starting UCM test two parameters must be set as follows: [A16- UCM CONTROLL = 1] [A06 DOOR BRIDGING = 1,2,3] After setting these parameters execute X04-UCM TEST function under Test-UCM icon in main menu (in previous versions R05-UCM TEST in SERVICES menu) to start UCM test. Automatic doors will be opened automatically. However, you should open semi-automatic doors manually. The lift will move and then stop when any of ML1 or ML2 switches are out of the door zone by creating UCM ERROR. If there is no error then it means that there is a problem either in wiring or position of the shaft elements. This error is stationary and must be cleared manually. Execute X01- UCM ERROR CLEAR (R01- UCM ERROR CLEAR in SERVICES menu) facilty to clear this error. This operation is explained in user manual in section 7.4.
