Program 63 – Functional phase monitoring (code 04)
This function monitors whether the column lift also rises when the UP button is
operated. It is displayed as code 04 on the 2x7 segment display as long as the UP
button is pressed.
The function is inactive when the code flashes.
Program 65 – Safe limits
This option is available so that the column can function outside the safe limits (1 1/4"
and 2 1/2"). This can be used to level the lift outside the safe limits. Activating
programme 65 disables the safe limit monitoring.
This setting is active during 10 minutes and then the safe limits will be
automatically activated and the system has to be restarted. The setting will not
be saved in the EEPROM so that the safe limits will always be active after
starting and stopping.
Note
n
Make program 65 active in each column to be able to operate a column set outside
the safe limits.
Program 66 - Potentiometers OFF (check of the potentiometer operation)
This option is available so that the value on the potentiometer input is replaced by a
constant value. The column will function normally without the elevation difference
being corrected.
This setting is active during 10 minutes and then the safe limits will be
automatically activated and the system has to be restarted. The setting will not
be saved in the EEPROM so that the safe limits will always be active after
starting and stopping.
Note
n
Make program 66 active in each column to be able to operate a column set with
deactivated potentiometers.
Program 67 – Reading/calibrating potentiometers (code 16)
The individual potentiometer value is set to the microprocessor of the relevant
column when calibrating potentiometers. A potentiometer generates an analogue
signal which is translated into an incoming digital signal to the microprocessor.
The calibration of the individual columns is performed in the factory.
