Proximity Switches KLE are part of the system and are fitted into the profile
grooves where they are secured using a grub screw, which locks the switch in
the groove.
The Proximity Switch cables run inside the groove and through the Reverse
Units. The cable is run out to the outside at a suitable point (by removing the
Caps of the Reverse Units).
The minimum distance is determined by the Carriage geometry and the contact
plate located on it:
KLE 6 60x60: d
min
= 80 mm + S
KLE 8 80x80: d
min
= 100 mm + S
This does not factor in the Carriage braking distance.
The Proximity Switch cables cannot be routed past a further Proximity Switch in
the groove! Consequently, a maximum of 4 Proximity Switches can be used for
each KLE.
Two different inductive Proximity Switches are available for each system size
(1 NO, normally open switch, 1 NC, normally closed switch).
The groove is closed using Cover Profile 6 60x60 or 8 80x80. The Cover Profile
is pressed over the cable to protect it from damage. There are gaps in the Cover
Profile at the locations of the Proximity Switches.
Commissioning
Proximity Switches
It is important prior to start-up to ensure that the rollers are lubricated (see
Section 6 - Maintenance).
The homing run serves as a final quality check.
The following factors must be checked:
▪
Are the conditions okay?
- Ambient temperature (10 °C–40 °C)
- Load
- Travel speed
- Travel distance
▪
Have all relevant elements been lubricated (see Section 6 - Maintenance)?
▪
Is there sufficient protection on all rotating parts, live electrical parts and
points where parts of the body may become trapped?
▪
Have all screws been tightened in line with requirements?
▪
Are all possible caps and covers, particularly over rotating parts, being used
and have they been locked in place.
A trial run must be carried out at low speed that takes in the entire travel path
and checks that the Compact Linear Unit is functioning correctly.
Possible faults may present as smoke or noise!
