5.3 Mounting the switches

Mechanical switches

• Solder cable to the switch.• Screw switch to the switch mounting

plate.• Fix switch mounting plate on the pro-

filed base by means of square nutsand screws.

• Set switching intervals by adjusting theswitches 5.3.1

Negative dimensions C indicatethat the switch projects above thetop edge of the carriage.

Proximity switches

• Screw switch to the switch mountingplate

• Attach the switch mounting plate tothe profiled base by means of slotblocks and screws

• Set switching intervals by adjusting theswitches. 5.3.2

Negative dimensions D indicatethat the switch projects above thetop edge of the carriage.

5.2 Mounting the profiled base

• Cut profiled base (1) to the requiredlength and remove burrs.

• Align the fixed bearing side bracket (2)on the profiled base (1) and screw itdown.

• Slide the second bracket (3) looselyonto the profiled base (1).

• Screw first bracket (2) tightly to thefixed bearing end block (4).

• Screw second bracket (3) to thefloating bearing end block (5).

• Screw second bracket (3) down onthe profiled base (1).

Close adherence to the above sequenceallows easy adaptation to the slide'slength.

In exceptional serviceconditions (e.g., vibrations, longerstrokes) the profiled base must besupported in the vicinity of switches.

5.4 Mounting the socket

€ Insert and fasten the socket in thesame way as the switches. 5.3

Two seals are provided for the cableentry into the socket. One seal haspredrilled holes for the cables of twomechanical switches and one proximityswitch.

5.7

If more or less switches are required,drill the appropriate number of cableholes in the other seal.Thread all cables through the com-pression screw (1), the seal (2), thesocket housing (3), and the cork seal(4), taking into account the desiredconnecting position of the plug (5).Close the unused opening (6) in thesocket housing (3) using the O-ring (7)and screw plug (8).Solder cable into flanged connector(9). Draw a pin allocation diagram.Screw the flanged connector (9)onto the socket housing (3) withscrews (10).Press the seal (2) into the housing andsecure with compression screw (1).Insert the socket in the profiled baseand fix it in place using set screws.Mount cable duct. Solder cable into the plug (11).Check the switching circuit function.

For major relocations, the cable ductsmust be modified or replaced. 5.7

Proximity switch cables cannot beextended as the cables are potted intothe switches. If a proximity switch with alonger cable is needed, the best solutionis to buy a new switch.

€ R emove the screws.€ Pull the inner frame (1) out of bellows.€ C ount the folds of the old bellows and

cut the new bellows to the appropriatelength.

Mounting the inner frame (1) andthe outer frame (2)

Insert the inner frame (1) into thebellows. The edges of the inner framemust be lodged behind the first com-plete fold in the bellows. The outeredges of the inner frame (1) must becompletely hidden.

€ C enter the inner frame (1).€ If the linear motion slide is installed

horizontally or in an inclined position,arrange the bellows so that the gluedjoint is on the underside.

€ Align the outer frame (2) with themount-ing holes on the carriage. Ifnecessary, turn the outer frame over.

€ S crew the outer frame (2) to the innerframe (1).
