9.5 LCD SCREEN
An LCD screen with two lines of 16 characters each has been provided to display more motor drive
control information. This shows the active operating mode of the motor drive or the movement status
of the motor in legible text.
The background of the display is lit for as long as the twist and selector switch is operated. 20
seconds after the last entry is made, the light is switched off. It can be switched on again at any
moment by turning the selector switch. The display is also properly legible in direct sunlight.
Illustration 16: Information on the LCD screen
After resetting the software or after switching on the power, the display light will blink for a
few seconds. This indicates that the processor is booting; it is not a fault condition.
If, prior to a reset, the gate is in the OPEN or PARTIALLY OPEN position and “Automatic closing” is
programmed, the following is displayed on the display:
"Auto.Closing ON"
"-------"
This indicates that the automatic timer must be restarted by using keys. Without this command, the
drive, after the control system has been switched on (reset), will not automatically operate.
