TOX®-Powerpackage Control Units.............................................................................................................................................................

There are various ways to adapt and optimise the normal
stroke of a TOX®-Powerpackage to individual requirements.
For this purpose we provide the following control units:
 ZHO: Stroke frequency optimisation ZDK: Pressure regulator in the power stroke line
 ZKHZ: External power stroke activation
 Preparation external power stroke activation
 ZKHF: External power stroke release
 ZKHD: Deactivation of the power stroke Preparation for external power stroke supply
 Preparation for fast approach stroke support

Control units in detail
Dynamic pressure control
Function: During dynamic pressure control, the automatic
switch from fast approach stroke to power stroke occurs
every time the working piston meets resistance at any pointof the stroke. The power stroke valve is connected to thereturn stroke chamber via the red control throttle X line andfunctions according to the dynamic pressure procedure.
The changeover time is controlled with the control throttle X.
Application: This control will be supplied by default if noother control was ordered.

Stroke frequency optimisation ZHO

Pressure regulator in the power stroke line ZDKFunction: The ZHO is an optional additional assembly for
improving the cycle time. The improvement during the power stroke and power stroke aeration time is approx. 20 %.
The ZHO assembly replaces the existing power stroke valve
with one of the next size. The control of the power stroke
valve is the same as for the standard TOX®-Powerpackage.
The control schedule of the dynamic pressure control thus
remains unchanged. For the ZHO, an additional fast aerationvalve is installed at connection 8 for TOX®-Powerpackages
with pneumatic spring.

Function: The ZDK enables individual adaptation of thepress force with a manually adjustable pressure regulator,including manometer. The pressure regulator can also be
installed further away (e. g. in the switch cabinet). No additional fast aeration valve is required. Alternatively, an electric
proportional pressure regulator can be installed in the powerstroke line.

Application: In particular if the cycle time must be reduced
for long power strokes.
Requirement: The ZHO can be attached to TOX®-Powerpackages as well as intensifiers (ES) of TOX -KT-Systems orupgraded in most cases. In order to optimise the cycle time,a main control valve corresponding to the enlarged powerstroke valve with suitable supply line must be available on
customer-side. The required size of the supply connection
is to be specified.

Application: For reducing the press force in the power stroke with the same level of fast approach and return stroke
force. Attention: Oil pressure min. 60 bar
Requirement: Can be attached to all TOX®-Powerpackages with power stroke valve. The required size depends on
the size of the power stroke valve.

External power stroke activation ZKHZ

Preparation for external power stroke activation

Function: The ZKHZ enables activa-tion of the power stroke valve with an electrically actuated 3/2-way valve.

Function: The TOX®-Powerpackage is prepared for an external power stroke activation on customer-side. The pneumatic filling and venting of the power stroke chamber occur
via the normal integrated or external power stroke valve.
The pneumatic signal for switching the power stroke valve ismade available on customer-side.

Application: Recommended for travel-dependent powerstroke connec-tion or when using the TOX®-Powerpackagewith upwards piston rod and high tool weight. Also usagefor application-related interrupted fast approach stroke (e. g.
for pressing a spring-loaded holding-down clamp or similar).
Requirement: Can be attached to all TOX®-Powerpackages. A permanent compressed air supply of the electrical
3/2-way valve with 3 - 10 bar (connection G 1/8“) is required.
Furthermore, an electrical switching signal (24 V) for activating the power stroke, e.g. a proximity switch ZHS 001 combined with the stroke request ZHU or the output signal of theposition encoder ZKW / ZHW.
Compatibility: Compatible with pressure regulator in thepower stroke line (ZDK) and/or stroke frequency optimisation (ZHO).
Note: Must only be used for TOX®-Powerpackages withpower bypass.

An electrical control valve for activating the power stroke
is not included in the scope of delivery. The control throttle
X connection on the TOX®-Powerpackage is closed by ascrew plug, the red control throttle X line is not needed. Input 14 on the power stroke valve remains open for control
on customer-side (see control schedule ZKHZ).
Application: If activation of the power stroke is realised bythe customer.
Compatibility: Compatible with pressure regulator in powerstroke line (ZDK) and stroke frequency optimisation (ZHO).

External power stroke release ZKHF

Deactivation of the power stroke ZKHD

Function: With the ZKHF it is possible to additionally release activation of the power stroke valve by means of dynamic pressure control with an electrical signal.

Function: With the ZKHD, the power stroke can be deactivated through an electrical signal (e.g. during setup mode).
The function is similar to the external power stroke release(ZKHF), but the electrical actuation of the power stroke isdisabled.

Application: If the power stroke could be actuated accidentally by the control throttle X due to interference contours
in the working area and shall thus be released additionally.
Requirement: Can be attached to all TOX®-Powerpackages. A permanent compressed air supply of the electrical
3/2-way valve with 3 - 10 bar (connection G 1/8“) is required.
Also an electrical switching signal (24 V) for releasing thepower stroke.
Compatibility: Compatible with pressure regulator in power stroke line (ZDK) and / or stroke frequency optimisation(ZHO).

Power stroke valve 6.1

Application: If a temporary deactivation of the power stroke is required, e.g. in setup mode.
Requirement: Can be attached to all TOX®-Powerpackages. A permanent compressed air supply of the electrical
3/2-way valve with 3 - 10 bar (connection G 1/8“) is required.
Also an electrical switching signal (24 V) for releasing thepower stroke.
Compatibility: Compatible with pressure regulator in thepower stroke line (ZDK) and / or stroke frequency optimisation (ZHO).

Preparation for external power stroke supply
Function: The TOX®-Powerpackage is prepared for an
external pneumatic supply at the input of the power stroke valve on customer-side. With this type of power stroke
supply this can also be permanent pressure unconnected oncustomer-side. At the TOX®-Powerpackage, connection 4.1
is reduced to thread size G 1/8“. Pressure is applied to thepower stroke valve via a thin connecting cable. The connecting hole in the power stroke valve is closed with the suppliedscrew plug.

Function: The TOX®-Powerpackage with pneumatic springis prepared for fast approach stroke support on customerside. The pneumatic connection between storage spaceand plunger return stroke chamber on the TOX®-Powerpackage is closed by a screw plug. Connection 4.2 to the storage chamber stays open for supply on customer-side. The
storage piston can thus receive more pressure and support
the fast approach stroke. The required control components
are not included in the scope of delivery.

The power stroke can be activated via a dynamic pressure
control or via an external activation or release.

Application: When a pneumatic fast approach stroke support is to be realised on customer-side.

Application: If a separate pneumatic supply of the power stroke valve is desired (independent of the fast approachstroke).

Requirement:spring.

Compatibility: Compatible with dynamic pressure control,
external power stroke activation (ZKHZ) or external powerstroke release (ZKHF) and stroke frequency optimisation(ZHO).
