When the cylinder has switched into the power stroke, and the sensor signaling „tool closed“ hasbeen met, the push buttons can be released. The cylinder develops the preset pressure and thenretracts.
Used for setup of the machine. Momentary activation of the 2-hand buttons results in a movementof the piston with reduced speed. The cylinder can be stopped at any desired position.
All required electric components, emergency reset, in-feed, function keys etc. are included.
Includes all required valves as well as an air servicing unit, as well as flow controls for approachand return speed.
Controls ordered without a press will be delivered with 3 meter long hoses and wiring.

3Additional Information on the TOX®-Controls

Basic operation of the electric TOX®-2-hand Controls when used with TOX®Presses
The cycle is initiated using the two
push buttons on the 2-hand safetycontrol. Both sensing devices mustbe activated within 0.5 seconds. The
working rod will advance throughthe fast approach stroke until itmeets resistance. This resistancewill shift the sequence valve andinitiate the power stroke. The TOX®Powerpackage remains pressurized as long as the push buttons
are activated. Once the preset oilpressure is reached, the pressure
switch sends a signal to the directional valve to retract the working
rod. Controls with the self locking
function initiate the return stroke
automatically regardless of whether
the safety push buttons are still activated. The working rod will retract assoon as the preset oil pressure has
been reached.

If any or both of the push buttons
are released prematurely, the TOX®Powerpackage will retract immediately.
After completing a cycle, a new one
can only be initiated after the 2-handsafety buttons have been released
during the return stroke of the previous cycle.

Safety:Activating the integrated emergency
reset button will introduce the returnstroke immediately in any operatingmode.
In case of a loss in air pressure,the working rod will not retract andcould drift down slowly.

Depending on the type of controls,
additional signals can be used, suchas parts presence sensors.
Complete process sequencing canbe realized using our PLC controls.

Standard version of the TOX®-Safety Control• Flow control valves to regulate
speed during approach and returnstrokes, air servicing unit, oil pressure switch to signal return stroke(not included with straight pneumatic controls)• For machines without a base orfor orders without a PC press, thecontrol elements will be supplied
separately including 3 m of connecting power lines. This applies also
to controls which are ordered witha TOX®-Powerpackage and are to
be mounted by the customer.

All controls are supplied according
to TOX® PRESSOTECHNIK specifications.
The buyer must ensure that anypresses and controls supplied byTOX® PRESSOTECHNIK conform toall applicable national and local Occupational Safety Hazard Guidelines.

TOX® PRESSOTECHNIK shall not beheld liable for any damage or injuries
resulting from neglect or misapplication. The buyer guarantees to TOX®
PRESSOTECHNIK that they willcomply with all applicable national
and local safety regulations prior touse of the equipment.
By definition, any pinch points along
the return stroke of the tooling area
must be properly guarded.

Safety recommendations for press controls with self locking function
For presses with 2-hand safetycontrols and using tools with an
opening > 6 mm, a sensor for “toolclosed” must be installed (seeoperating manual) according to theguidelines provided in the DIN EN

4

www.tox-pressotechnik.com

16092 standards. The sensor must
be installed in such a way that it will
provide a signal once the tooling isclosed. if the tool opening is ≤ 6 mmor the tooling area is guarded (e. g.

TB 100.30_201609.en

perimeter guarding), then this sensor
is not required.
The sensor serves as a fail safe
method of the command for the self
locking function.
