2.5 Prerequisites
Prerequisites
Machines with vacuum pump have a higher energy and a lower compressed air consumption than ma-
chines without a vacuum pump (see "2.2 Energy and Compressed Air Consumption" [ ➙ 81]).
Adjust the power and compressed air supply to the relevant specifications.
The C&P20 A head must be converted for use with a vacuum pump using the vacuum pump operation
conversion kit for C&P20 A [00119790-xx] (see "3.5.1 Conversion for C&P20A/P" [ ➙ 113]).
The C&P12 head (DLM) must be converted for the use with a vacuum pump using the 119796 vacuum
pump operation retrofit kit for C&P12 (see "3.5.2 Conversion for C&P12" [ ➙ 116]).
2.6
2.6 Restrictions
Restrictions
The TwinHead and CPP placement heads are not compatible with vacuum pump operation.
The pressure control valve needs to be operated with compressed air for all placement heads.
The TwinHead is generally supplied via the pressure control valve. Conversion to vacuum mode is there-
fore not possible.
In CPP heads, the holding circuit is not designed for vacuum operation.
The placement heads must be refitted according to the machine configuration.
▪ The C&P20A/M for compressed air mode is delivered with vacuum generator.
▪ The C&P20 P is delivered with a aperture ring for vacuum pump mode.
NOTICE
Return cylinder unable to move out
Do not convert the pneumatic supply for the gantry affected to vacuum mode. If the compressed
air supply for this head is converted to vacuum operation, the return cylinder will be unable to
move out and the Z axis will remain in its top position.
NOTICE
Aperture rings
The aperture ring cpl. CP20p [03108716-xx] and the aperture ring cpl. C+P20 [03046348-xx]
are not compatible.

2.7 Vacuum Pump - Special Features
Vacuum Pump - Special Features
The vacuum pump is switched on and off together with the machine, although the software automatically
takes into account a stopping time of 6 minutes on switch-off, to prevent the motor overheating from the
inrush current peaks.

2.8 C&P20A/P Placement Head - Special Features
C&P20 A/P Placement Head - Special Features
An SX series vacuum pump can supply a maximum of two C&P20A/P heads.
When retrofitting the vacuum pump option, the Venturi vacuum generator for the C&P20 A head ("vac-
uum unit holding circuit C&P20 A“) is replaced with the "aperture ring assembly C&P20" [03046348-xx].
On C&P20A/P heads, only the hold circuit is supplied directly by the vacuum pump.
Irrespective of this, the pressure control valve and the return cylinder are still supplied with compressed
air in the pickup and place positions.
The "vacuum consumption" of the placement machine depends only on the number of placement heads
and the size of the nozzles. The more C&P20A/P heads are connected to the vacuum pump, the lower
the vacuum level will be at the nozzles.
When the placement operation begins, the vacuum increases with each component picked up. An aver-
age vacuum value will soon form, based on the number of nozzles closed at the same time (with picked
up components) and number of nozzles open (components placed).
NOTICE
Maximum of two C&P20 A/P heads per vacuum pump, each machine separate.
The vacuum pump used here can supply a maximum of two C&P20 A/P heads. If using an SX4
with four C&P20 A/P heads, you therefore need two vacuum pumps.
The vacuum pump is connected to the power supply for the SX1/SX2 and may only be operated
when the machine is switched on. Each machine in the line which has been converted for vac-
uum operation must therefore have its own vacuum pump.
NOTICE
Maintenance
Always observe the additional service instructions for the vacuum pump.
