Adjusting the bearing load
• Before setting the bearing load, affix the load with the cable fully retracted.
CAUTION!
• Adjusting towards "Plus" (+) increases the bearing load.
• Adjusting towards "Minus" (-) reduces the bearing load.
• The setting is correct when the affixed load is easily drawn into the required position and
after being released returns to its initial position.
• The spring balancers leave the factory with the "Maximum load" setting.
The following adjustments are to be adjusted from the "Maximum load" again and again.
Please refer on this to the specific-type particulars.
Not heeding this instruction can result in the springs in the housing being ruined.
• ER00 and ER11:
Pressing in the spring lock (11) causes the pre-tension to act on the adjusting tool. Keep
the adjusting tool firmly held!
• Adjusting operation ER00 to ER12:
– Tensioning:
Insert the hexagonal key into the spring lock (11)
and turn clockwise
– Stress-relieving:
Insert the hexagonal key into the spring lock (11),
press inwards and turn anti-clockwise.
Caution !!!
The spring lock (11) must have the possibility on the
opposite side to move out of the housing.
• Adjusting operation ER21:
Insert the hexagonal key into the adjusting screw (14).
Use an hexagonal key to undertake the required
adjustment within the permitted adjustment range.
The adjusting screw (14) acts upon the spring lock
(11) which has a marking on the outside. The
adjustment can be seen at this marking.
• Column "X" = maximum permitted rotations towards
"Plus" with the spring fully stress-relieved. The spring
is fully stress-relieved when the rubber buffer (13) on
being
stress-relieved detaches itself from the
housing.
