Models AT-GM-13A and AT-HM-13A Two-Hand Control Modules
Feedback Open
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 5).
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
can be accomplished by their mounting position and/or through the use of protective
shields such as rings, guards or shields; see Figure 3.
NOTE: Two-hand control and two-hand trip safeguarding protect only the operator’s
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 4 and Separation
Distance on page 5) and when properly interfaced to the machine (see Electrical
Installation on page 6) to control the required stopping action.
each machine cycle, before a new cycle can be initiated (see Caution at left).
The actuating devices must be protected from accidental or unintended operation. This
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.

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 4 and Separation Distance on
page 5) and when properly interfaced to
the machine (see Electrical Installation
on page 6) to prevent accidental cycle
initiation.
