1. to 4.: Location 1 to 4
5.: Proportional controller top and bottom
 NOTICE!
Only one proportional controller is fit-
ted for vacuum pump mode (all
heads).
When converting to compressed air
mode (Twin and CPP), you need to fit
a second proportional controller.
Also read the assembly instructions for
the vacuum pump.

Fig.117: Proportional controller configurations
Configurations
Depending on the configuration, there will be
one or two proportional controllers fitted.
1. One proportional controller (bottom)
Only one proportional controller is fitted,
if the machine is operated exclusively
with SIPLACE C&P20x in vacuum
mode.
2. Two proportional controllers (top and
bottom)
Two proportional controllers are re-
quired in all other cases (mixed head
mode or compressed air mode).
Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Switch off the compressed air supply and then disconnect the machine from the compressed
air supply.
5.2 "Disabling the compressed air supply" [}86]
► To do this, remove the screws fastening the side cover at location 4 and remove this cover.
5.5 "Dismantling the Lower Side Cover" [}88]
► Unplug the electrical connection to the proportional controller.
► Remove the screws fastening the proportional controller and then remove the controller.
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instructions:
► Observe the instructions in section 5.4 "Sealing the Pneumatic Screwed Connections" [}88].
Fig.118: Overview proportional controller (version2)
► Clean the sealing rings(1)and the adap-
ter plate(2)
.
► Lightly grease the sealing rings with
Isoflex Topas NCA52 and insert these
again into the adapter plate.
► Fit the adapter plate with five fastening
screws(3)
(torque: 2.5Nm, Loc-
tite241).
► Fit the proportional controller(4) with
three fastening screws(5)
(torque of
2.0 to 2.5Nm, Loctite241).
