Lengths and diameters of compressed air supply lines
 Flexible lines must be as short as possible in order
to minimize response times.
Make sure there is no pollution in the device
connections and lines.
 Flexible lines must be connected without bends
and without crushing them.
9.2. Pneumatic Connection
NOTE: MODULE PROTECTION
Removable 100μm lter screen integrated in the vacuum connection to protect the pump against particles.
Possible additional lter on vacuum circuit: In the rare cases of ne dust in a wet environment, the use of an appropriate lter will
prevent any internal clogging: See COVAL catalog: “Filters for vacuum circuits”
IF THESE CONDITIONS ARE NOT OBSERVED, YOU RISK THE FOLLOWING ISSUES:
If the chosen internal diameter on the compressed air inlet is too small, the compressed air supply will be insucient to
achieve optimal performance. The generator will be unable to achieve the specied maximum vacuum rate.
If the chosen internal diameter on the vacuum inlet is too small, the airow is slowed down due to this restriction, which has
a negative effect on suction power and on suction or exhaust time.

Reminder: The remote HMI (part no. HMIHD1M84P) can only be used
withvacuumgrippersCVGL_S2/V2 (equippedwithCMSHDE___VX__
multi-stage vacuum pumps).
The CMSHDE___VX__ multi-stage vacuum pumps are supplied
with the standard factory settings described in this manual. To be
able to modify them, you must use a remote HMI or congure the
module using IO-Link.
Conguration procedure
Step 1: Connect the remote HMI to M8 connector (marked ) on
the CMSHDE. The CMSHDE must be powered on.
Step 2: When the HMI is powered on, a message is displayed asking
which settings should be used (HMI or IO).
Transfer and apply settings from the HMI module? YES/NO?
Step 3: Choose either YES or NO.
NO (selected by default): If the user presses M or does nothing within 5seconds, the settings present in the vacuum switch of the
CMSHDE are transferred to the remote HMI.
YES: The process settings and device settings contained in the remote HMI are transferred to the vacuum switch of the CMSHDE and
applied immediately.
This operation can be used to copy settings from one product to the next. The device’s own product ID, serial number and device name
remain unchanged. Likewise, the display settings (language, vacuum and pressure units, display rotation), also called “user settings”, are
not transferred since they are only related to the remote HMI.
