MAINTENANcE AND SErvIcE
9.2.2.1 Checking the air gap X
Easy control of the air gap:
► Ensure that the brake is in a de-energised state.
► Check the air gap between the magnet housing and the armature with a feeler
gauge. This is usually sufficient.
► When the limit value is nearly reached, an accurate air gap measurement must be
made.
Accurate measurement of the air gap with a lever gauge:
► Connect the brake to rated voltage (armature must be applied to the magnet).
► Place the feeler lever at a point on the anchor surface (=>
“Figure 21: Checking the
air gap”
).
► Adjust the lever gauge with dial gauge (zero position).
► Switch off the supply voltage (armature falls off the housing).
► The air gap "
X
Limit
“
is the difference between zero position and displayed value.
► Repeat the measuring process at three different positions (approx. 3 x 120°).
► If a value greater than " X
Limit
“ is measured, the wearing parts must be replaced
(=> “9.2.4 Replacing the lining” ) or an adjustment must be made if possible
(=> “9.2.3 Readjust air gap” ).
► The teeth of the lining and the hub must be checked regularly. Worn parts must be
replaced.
