The Banner DUO-TOUCH SG Two-Hand-Control safety system provides a measure of protection for the operator against reaching
danger zones during hazardous situations by locating the control actuating devices in a specific position and monitoring the
actuating devices for specific conditions.
In Europe, the functions that the Banner DUO-TOUCH SG Two-Hand-Control safety system is intended to perform are regulated by
the CEN (European Committee for Standardisation) and the CENELEC (European Committee for Electrotechnical Standardisation).
Whether or not any particular DUO-TOUCH SG Two-Hand-Control system installation meets all applicable European and inter-
national requirements depends upon factors that are beyond the control of Banner Engineering Corp. These factors include the
specific ways the safety module is applied, installed, wired, operated, and maintained.

WARNING ... Point-of-Operation Guarding
When properly installed, the DUO-TOUCH SG Two-Hand-Control Safety Module provides protection only for the hands of the
machine operator. It may be necessary to install additional point-of-operation safeguarding, such as safety light curtains and/or
hard guards, to protect personnel from hazardous machinery. Failure to install point-of-operation guards on hazardous machin-
ery can result in a dangerous condition which could lead to serious injury or death.

DUO-TOUCH SG Safety Module Description
A DUO-TOUCH SG Two-Hand-Control Safety Module may be used with:
• 2 Banner STB Self-Checking Optical Touch Buttons, each with one normally open
and one normally closed relay output contact, or
• 2 Banner STB Self-Checking Optical Touch Buttons, each with two current-sourcing
PNP outputs, or
• 2 mechanical push buttons with one normally open and one normally closed
contact each (Form C contact)
If the machine operator removes one or both hands from the STB(s), the Duo-Touch
SG relays de-energise, causing the output contacts to open. The relays will not re-
energise until both STBs are deactivated and then simultaneously reactivated.
The Duo-Touch SG Two-Hand-Control Kit system is certified to:
• Type IIIC requirements of EN 574/ISO 13851 Safety of Machinery – Two-Hand-
Control devices, and
• Category 4 requirements of EN 954-1/ISO 13849-1 Safety of Machinery – Safety-
Related Parts of Control Systems – Part 1: General Principles of Design
The Safety Module’s output signal consists of two sets of redundant, forced-
guided (mecahnically linked) contacts (see Figure 5 page 9). Circuitry within the
Safety Module monitors these internal contacts and prevents an output signal from
occurring if a fault is detected. A feedback loop is offered for monitoring the status of
the machine control elements.

Appropriate Applications
The DUO-TOUCH SG Two-Hand-Control Safety Module may be used as an initiation
device for most powered machinery, where machine cycling is controlled by a
machine operator.
When using a two-hand-control system for safeguarding, both of the operator’s
hands must be used to initiate the machine cycle. In effect, this makes the operator
a “hostage” while the hazard is present, thus limiting or preventing exposure to the
hazard. The two-hand-control actuators must be located so that hazardous motion
(for example, closing of the die) is complete or stops before the operator can release
one or both of the buttons and reach the hazard (see page 7, Minimum Safety
Distance).
Concurrent use of both hands is required, meaning that both buttons must be
actuated simultaneously – within a very short time span. This time span is specified
by EN 574/ISO 13851 as not more than 500 ms, even under single-fault conditions.
This requirement not only reduces the possibility of intentional defeat, but also
reduces the chance of unintended initiation of the machine cycle.
The machine control, when used in single cycle or single stroke mode, must provide
an anti-repeat feature so that at the end of one machine cycle, further cycles are
prevented and the operator must release the two-hand-control actuators before the
next cycle can be initiated (see Caution at right).
The STB Touch Buttons must be protected from accidental or unintended operation.
This can be accomplished by their mounting position and/or through the use of
protective shields such as rings, guards or shields. Suggested methods are shown on
page 6.
It should be noted that two-hand-control and two-hand-trip safeguarding protect only
the operator’s hands. Additional safeguarding or other appropriate standards may be
required.
The user must refer to the relevant standards for additional requirements for
the application of two-hand-control and two-hand-trip devices when used as a
safeguarding means.
CAUTION ... Not an
Anti-Repeat Control
Device
Anti-repeat control is not a function
of the DUO-TOUCH SG Two-Hand-
Control Safety Module. The user of this
device must provide a suitable means of
accomplishing anti-repeat control for any
single-stroke or single-cycle machine.

Part-Revolution Clutched Machinery
EN 692 “Mechanical Presses – Safety” allows a two-hand-control safety module to operate part revolution power presses for any
of the following functions: “inch” (jog), “single-stroke” or “continuous” (run). Two-hand-control safety modules are recognised
as a means of protecting the machine operator when the hand controls are safely located and protected from false operation
(see pages 6 and 7) and when the two-hand trip device is properly interfaced to the machine (see pages 8 and 9) to control the
required stopping action.
Full-Revolution Clutched Machinery
A two-hand-control safety module used to initiate the cycle of a full-revolution clutched machine is known as a “two-hand-trip
device.” Two-hand-trip devices are recognised by CEN and CENELEC as a means of protecting the machine operator when the
hand controls are safely located and protected from false operation (see pages 6 and 7) and when the two-hand-trip device is prop-
erly interfaced to the machine (see pages 8 and 9) to prevent accidental cycle initiation.
Theory of Operation
The input circuit of the DUO-TOUCH SG Safety Module requires simultaneous actuation of both two-hand-control actuators to
generate an output signal. European standard EN 574/ISO 13851 requires that the two hand controls be actuated within 0,5
seconds of each other.
The timing diagram in Figure 2 (page 4) illustrates that an output signal from the DUO-TOUCH SG Safety Module occurs only if
switch #1 (SW1) and switch #2 (SW2) are actuated within 0,5 seconds of each other. The total response time (from the time the
devices are disengaged until the module’s output contacts open) is 0,035 seconds + 0,020 seconds = 55 milliseconds. The device
output does not re-energise until both hand controls are disengaged, and then simultaneously re-actuated. This logic reduces the
possibility of defeat of the two-hand-control by tying down one or both hand controls.
STB Touch Button Description
STB Self-Checking Optical Touch Buttons are identical in fit and form with the proven and popular OTB Series buttons. The internal
design of the new buttons, however, based on diverse-redundant microcontrollers, allows the wiring to a Banner DUO-TOUCH
SG Two-Hand-Control Safety Module designed and certified to Type IIIC per EN 574/ISO 13851 (requiring 1 normally open and 1
normally closed contact per input channel).
The STB is a photoelectric “beam-break” activation device that incorporates a self-checking optical circuit designed to detect
internal safety-critical faults. Both the emitter and receiver are continuously exercised and monitored via secondary photoelements.
If a fault is detected, the microcontrollers will hold the outputs in the OFF state and flash a Fault LED to alert an operator.
All models are supplied with a yellow polypropylene field cover to prevent inadvertent switching.
