The
patented Pinnacle UltraTouch system has been designed
as a direct replacement for standard spring loaded mechanical
palm buttons and is designed to fit into existing operator palm
button stations without modification.
The UltraTouch
enclosure is a molded high strength NEMA 4 polycarbonate module
designed to meet the high impact and vibration requirements of
industry. The solid state electronics of the UltraTouch
switch incorporates an advanced redundant diverse sensor design.
This means that each module has two different sensors with isolated
circuits along with a monitoring redundant circuit. The circuitry
of the UltraTouch is also designed to provide second-order
failure protection. This gives the UltraTouch an unparalleled
level of safety and assurance against inadvertent actuation,
or failing in the "on" or conducting mode, which is
a common problem found throughout industry with competitive ergonomic
switch replacements. The UltraTouch design is so safe
against inadvertent actuation, that two UltraTouch modules
when spaced and located properly in accordance to OSHA and ANSI
hand control distance formulas (the same formula is used for
mechanical palm buttons), permit its use as an operator safety
two hand control device. The UltraTouch dual dissimilar
sensor format is designed for the machine operator to actuate
the switch, and that no inadvertent foreign objects such as a
sleeves, insects, broomsticks, playing cards, rags, mists or
droplets can activate or trigger the switch. This gives UltraTouch
an unparalleled level of safety while giving the operator the
benefit of using the correct ergonomic hand position of neutral,
0° deviation and 100% hand power.
UltraTouch
Configuration
The UltraTouch dual dissimilar sensor ergonomic palm switch
is configured in the following manner:
 The U-shaped sensors
actuation channel provides a triggering point for the machine
operators hand. This is where the invisible infrared light beam
is located and is crossing the channel. There is also a unique
U-shaped location sensor mounted on the inside of the UltraTouch
enclosure that hugs the sensor channel and is insulated by the
enclosure itself. When the machine operator inserts their hand
into the sensors actuation tunnel, both the infrared sensor and
the location sensor must be satisfied in order to energize an
electromechanical relay to send a cycle start signal to the machine.
Both individual sensors within each module are time interlocked,
and if both sensors are not triggered concurrently by the operators
hand, the UltraTouch output will be inhibited to the machine
control. The module also contains two visible LED indicators
which informs the status of the UltraTouch module to the
operator. A green LED indicates that the relay contacts are closed,
both sensors have been activated and no failures have been detected.
The red LED indicates that the relay contacts are open and no
satisfactory conditions were detected on both sensors. This advanced
patented UltraTouch design is not available on any competitive
units and gives the UltraTouch user an unparalleled level
of safety when using ergonomic zero force actuation devices.
Additionally, the operator will be activating the machine properly
by using the correct ergonomic hand position of neutral, 0°
deviation and 100% hand power.
Easy
to Install
UltraTouch installs with ease and comes with complete
installation instructions. Simple module design permits direct
exchange for existing spring loaded mechanical palm buttons and
even utilize the existing screw holes on the run bar. All systems
have normally open (NO) and normally closed (NC) contacts, and
are also available in a four (4) pole wiring configuration depending
on the machine control requirements. The ultimate in versatility!
New installations
and retrofit projects are completely installed in minutes by
a qualified electrician. Also supplied is a toll free 800 number
if any questions should arise by your installation personnel.

The mounting locations of UltraTouch must conform to all
State, Province and Federal codes and all regulations pertaining
to the subject machine on which the UltraTouch is to be
applied.
Point
of Operation Guarding
The UltraTouch System is a machine cycle initiation component
that is designed to be a two-hand control device for the machine
operator. If a point of operation guarding device is desired
or required, please contact your local Pinnacle distributor or
the factory for devices to comply with ANSI B11.1 or the various
OSHA regulations.
(Below
standards are only partial)
American National Standard B11.19-1990
4.2.4.2.3
Two-Hand Control Devices.
The two-hand control shall be designed to protect each hand control
against accidental or unintentional operation.
The two-hand control shall have the individual operator's hand
controls arranged by design, construction, or separation to require
the use of both hands to cycle the machine tool.
The two-hand control shall be designed to require concurrent
operation of both the operator's hand controls to cycle the machine
tool.
If more than one operator is to be safeguarded by the use of
two-hand controls, each operator shall have individual operator's
hand controls. The selection of the operator's controls shall
be capable of being supervised by the employer. Additionally,
each selected two-hand control shall be concurrently operated
before the machine tool is cycled. The two-hand control system
shall be designed and constructed so as to prevent cycling of
the machine tool if all the operator's stations are deselected.
The two-hand control shall be designed to require the release
of all selected operator's hand controls and the reactuation
of all operator's controls before a machine cycle can be initiated.
4.2.4.3
Operation
4.2.4.3.1 It shall be the responsibility of the employer to ensure
that the two-hand operating lever, trip, or control device is
installed, operated, and maintained in accordance with this standard.
4.2.4.3.2 The device shall be located at a distance from the
nearest hazard such that the operator cannot reach the hazard
with a hand or other body part before cessation of motion of
the hazardous portion of the machine cycle. The two-hand operating
lever trip, or control device shall require concurrent actuation
of both of the operating levers or hand controls to initiate
a machine cycle.
4.2.4.3.3 The two-hand control device shall require the concurrent
actuation of the operator's hand controls during the hazardous
portion of the machine cycle such that the operator cannot reach
the hazard before the hazardous motion has ceased.
OSHA
Federal Register Section 1910.217
(v) Two-hand controls for single stroke shall conform to the
following requirements:
(a) Each hand control shall be protected against unintended operation
and arranged by design, construction, and/or separation so that
the concurrent use of both hands is required to trip the press.
(b) The control system shall be designed to permit an adjustment
which will require concurrent pressure from both hands during
the die closing portion of the stroke.
(c) The control system shall incorporate an anti-repeat feature.
(d) The control systems shall be designed to require release
of all operators' hand controls before an interrupted stroke
can be resumed. This requirement pertains only to those single-stroke,
two-hand controls manufactured and installed on or after August
31,1971.
(vii)
The two-hand control device shall protect the operator as specified
in paragraph (c)(3(i)(e) of section 1910.217
(a) When used in press operations requiring more than one operator,
separate two-hand controls shall be provided for each operator,
and shall be designed to require concurrent application of all
operators' controls to activate the slide. The removal of a hand
from any control button shall cause the slide to stop.
(b) Each two-hand control shall meet the construction requirements
of paragraph (b)(7)(v) of this section.
(c) The safety distance (Ds) between each two-hand control device
and the point of operation shall be greater than the distance
determined by the following formula:
Ds=63 inches/second X Ts: where: Ds-minimum safety distance (inches):
63 inches/second=hand speed constant and Ts-stopping time of
the press measured at approximately 90 position of crankshaft
rotation (seconds) .
(d) Two-hand controls shall be fixed in position so that only
a supervisor or safety engineer is capable of relocating the
controls.
