7.4. Low Limits
7.4.1. Low Limit Menu
A low limit can be set by entering a known height on the keypad or by
manually moving the machine to the desired limit.
Using the Low Limits Menu, the low limit can be switched ON
and OFF, a low limit can be set to a known value, or the low
limit can be set to the current lowest point.
See sections 7.4.2 to enter a known low and section 7.4.3 for
setting the limit by moving the machine.
With a Low limit set, the screen will normally display the current lowest point value. To display the current
limit value, exit to the full screen and hold any button for three seconds, the value will then turn blue
indicating it is the current limit value.
Once a limit is set, the internal alarm will sound and the RED LED will
light if the equipment exceeds the current limit. Always check that the
current limit activates at the set point. The restriction cannot be
deactivated if in the alarm state. Observe the operational limitations
given in section
