Entering service modes
The Flow2A has 9 different modes: user mode -0- and service modes -2- till -9-. When the lift is switched on, the
default mode is -0-. In this mode the lift can be operated by the joystick on the armrest or by the call and park unit or
the attendant control.
For entering the service mode -2- till -9- a password has to be entered. This password can be entered by pressing
and holding the E button on the service board for 2s. A dot is lit on the most left display segment, indicating that this
value can be changed. Changing the value can be realised by pressing the D or I button. By pressing the E button
the dot will move to the display segment on the right side. After entering the 3 values for the password (245) the E
button must be pressed and hold for 2s to enter the service mode. The middle segment of the display will show a 2
and the left and right segments will show blinking -. This means service mode 2 can be entered just by pressing the
E button or another service menu can be selected by pressing the D or I button.
The function of each service menu will be described in section 4.4.3.
Exiting the service mode can be done by switching off and on the lift.
