WARNING
... Point-of-Operation Guarding
!
When properly installed, the DUO-TOUCH SG Two-Hand-Control Safety Module pro vides pro tec tion 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 per son nel from haz ard ous ma chin ery. Fail ure to install point-of-operation guards on haz ard ous ma chin-
ery can result in a dan ger ous con di tion which could lead to serious injury or death.

Two-Hand-Control Kits with STB Touch Buttons
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)
K1
If the machine operator removes one or both hands from the STB(s), the Duo-Touch
K2
SG relays de-energise, causing the output contacts to open. The relays will not re-
24
energise until both STBs are deactivated and then simultaneously reactivated.
Safety
A2 The Duo-Touch SG Two-Hand-Control Kit system is certified to:
S22
• 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.
