Operation & Service Manual (VA) 61 ST1175
7.8.5 Program 64 - CE-stop
If this function is activated, the column stops lowering at a height of 10" or more.
To continue lowering, the buttons must be released and activated again. The
column lift will continue lowering with an intermittent audio signal. Within this range
an intermitting signal will always be present during lowering.

Blinking (default) = no CE-stop,

Steady = CE-stop.
7.8.6 Program 65 - Safe limits
This option is available so that the column can function outside the safe limits
(1 3/16" and 2 3/8"). This can be used to level the lift outside the safe limits.
Activating program 65 disables the safe limit monitoring.
This setting is active for 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.

Make program 65 active for each column in order to operate a column set outside
the safe limits.
7.8.7 Program 66 - Potentiometers OFF (check potentiometer
operation)
This option is available so that the value on the potentiometer input can be
replaced by a constant value. The column will function normally without the
elevation difference being corrected.
This setting is active for 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.

Make program 66 active for each column in order to operate a column set with
deactivated potentiometers.
