Appropriate anti-repeat control must be
provided by the machine control and is
required by U.S. and International
standards for single-stroke or single-
cycle machines.
The AT-..M-11KM DUO-TOUCH SG
Two-Hand Control Safety Module can be
used to assist in accomplishing anti-repeat
control, but a risk assessment must be
accomplished to determine the suitability of
such use.
Muting is allowed only during the
non-hazardous portion of the machine
cycle.
A muting application must be designed in
such a manner that the level of integrity of
the safety system to be muted is not
reduced.

The DUO-TOUCH SG Two-Hand Control Safety Module may be used as an initiation device
for most powered machinery when machine cycling is controlled by a machine operator.
Using a two-hand control system 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 in a way that hazardous motion is completed or stopped
before the operator can release one or both of the buttons and reach the hazard (see
Separation Distance on page 8).
Simultaneous use of both hands is required, meaning that both buttons must be actuated
within a very short time span. The time span is specified by ANSI/RIA R15.06,
ANSI/NFPA79, and ISO 13851 (EN 574) as not more than 500 ms, even under single-
fault conditions. This requirement reduces the possibility of intentional defeat and
unintended initiation of the machine cycle.
When used in single-cycle or single-stroke mode, the machine control must provide an
anti-repeat feature so that the operator must release the two-hand control actuators after
each machine cycle, before a new cycle can be initiated. In addition to the anti-repeat of
the machine control, the mute inputs (M1 and M2), the Safety Stop Interface (SSI), or
Backdoor Timer also may be used to halt a machine cycle (see Caution at left).
The actuating devices 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; see Figure 7.
NOTE: Two-hand control and two-hand trip safeguarding protect only the operator’s
“Muting” of the two-hand control can only occur during a non-hazardous portion of the
machine cycle. When the hand controls are muted, the operator’s hands may be removed
from the devices, but the Safety Module’s outputs remain closed.
A mute cycle can be initiated after the Safety Stop Interface (SSI) is closed and the two-
hand control buttons are activated. After the Mute Enable input closes, M1 and M2 can
close (within the 3-second simultaneity requirement), then the Module will start a mute
cycle, light the mute lamp, and latch the outputs ON. The outputs will remain ON until
M1 or M2 opens, the SSI opens, the backdoor timer expires, a lockout occurs, or the
Module loses power.
Part-Revolution Clutched Machinery
A two-hand control safety module can be used for the following functions: “inch” (jog),
“single-stroke,” or “continuous” (run). Two-hand control safety modules are recognized as
a means of protecting the machine operator when the hand controls are safely located and
protected from false operation (see Mechanical Installation on page 7 and Separation
Distance on page 8) and when properly interfaced to the machine (see Electrical
Installation on page 8) 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 recognized as
a means of protecting the machine operator when the hand controls are safely located
and protected from false operation (see Mechanical Installation on page 7 and
Separation Distance on page 8) and when properly interfaced to the machine (see
Electrical Installation on page 8) to prevent accidental cycle initiation.
hands. Additional safeguarding 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 for safeguarding.
