6.8.5.3 Vacuum distributor disk star
At the DLM 2 C&P head the vacuum distributor disk for the holding and placement circuit is glued
to the star assembly. By application of the new vacuum distributor disk the leakiness between star
assembly and distributor disk is eliminated as well as squeaking noises.
The gluing of the distributor disk ensures the clean sealing of the vacuum system.

6.8.5.4 Vacuum distributor / silencer
The adaptation of the new vacuum generator allows the application of the DLM 2 C&P head on
the machines HS-60, S 27HM and SIPLACE HF. The compressed air supply is made by a distri-
butor block fixed below the head PCB. From this distributor block two pneumatic hoses run to the
inlet
(2) of the vacuum generator. The exhausting air is guided through a silencer and parially
through a hose connected to the silencer
(1). The hose runs underneath the head PCB to the dis-
tributor block where the exhausting air emits to the environs. On the SIPLACE HF the exhausting
air is used for cooling linear motor of the X-axis.

6.8.5.5 Encoder disk of the valve drives
The encoder disk (1) of the valve drives show additional slots (3) which allow a smoother position-
ing of the plungers
(5). Due to the additional slots resp. the increased angle resolution it is possible
to control the speed and to prevent bouncing of the plungers. Fig. 6.8 - 5 shows a valve drive with
excenter
(2) and fork light barrier (4).

6.8.5.6 Turning station ’DP-station’
The turning station of DLM 2 head and DLM 1 head have the same order no. The mounting of the
DLM 2 head is now fixed from the front with a M4 screw. The belonging thread is situated in the
turning station.
On the DLM 1 head the turning station was fixed from the back with a M3 screw through the M4
thread on the front part of the head.

6.8.6 Zeropoint correction star axis DLM 2
The switch for the track resolution must be checked case in case of a replacement of the C&P
head.
– On HS-60 and S-27 HM this switch is set to
10 x.
– On the SIPLACE HF this switch is set to
25x.
Please observe the following items in case of manual setting of the zero point correction:
– The procedure for the setting of the zero point gauge stays the same.
– The attachement point for the star axis gauge is situated a little lower, so that the pin for cen-
tering segment 1 might not snap in the segment guidance at once. In that case the Z-axis must
be pulled downward until the pin snaps in the segment guidance.
