Weh TW57, Руководство по эксплуатации

Страница: 19 / 60

Î The WEH
®
Connector is not fitted with an integrated shut-off valve and thus will not
prevent loss of medium in case of improper connection or after disconnecting. Apply
pressure to the connector only once it has been properly connected. It is important
to disconnect the connector only under absolutely safe conditions. In particular, the
connector must be fully depressurized during the connection process.
8�2 Connection
Connecting a TW57 with bail actuation and actuation lever
Î Fold the actuation unit (Pos. 1) upwards ( Figure 3 ).
Î Put the connector loosely and straight onto the cylinder
valve until a noticeable seal contact has been established.
Doing so will prevent any damage to the front seal caused
by any sharp edges on the cylinder valve and ensure a
correct connection.
Attention: Make sure that the connector is pressed onto
the cylinder valve until a noticeable seal contact has been
established.
Note: Put the connector with RPV pin onto the cylinder valve
until the RPV pin is pushed open in the cylinder valve and the
sealing piston creates a seal.
Î
Fold the actuation unit (Pos. 1) downwards ( Figure 4) . It
must be possible to lower the actuation bail easily and
without any force. In its end position, the actuation unit
must be below the horizontal of the connector ( Figure 5 ).
Attention: If the clamping jaws do not grip correctly at the
cylinder valve, if the actuation unit is not below the
horizontal or if the red marking on the front part is visible,
then the connector is not properly connected. The
connector may spring out of place and medium may
escape.
Î Pull lightly on the connector in the direction opposite that
of the connection to make sure that the connector is firmly
in place.
- The connector is now connected pressure-tight to the
cylinder valve.
Î Open the cylinder valve.
Î
To start the filling process, apply pressure to media inlet
“B1”.
Attention: The safety peg (Pos. 5) at the connector must
be extended after pressure is applied ( Figure 6 ). The
actuation is blocked, the connector cannot be
disconnected when it is pressurized.
