Models AT-GM-11KM and AT-HM-11KM with Muting and Safety Stop Interface Inputs
For the latest technical information about this product, including specifications, dimensions, and wiring, see www.BannerEngineering.com
Features
Diverse-redundant microcontrollers
Supplies power and monitors two Banner STB Self-Checking Optical Touch But-
tons, or two mechanical push buttons
Two redundant, forced-guided (mechanically linked) output contacts rated at 6 A
Two auxiliary solid-state outputs (NPN and PNP), plus auxiliary N.C. relay output
Feedback input monitors external machine control elements
Seven indicator LEDs for Power, Fault, Input 1, Input 2, SSI, Mute, and Output
24V dc plus 115V ac or 24V dc, 230V ac operation, depending on model
DIN-rail-mountable 67.5 mm-wide housing with removable terminal blocks
500 ms (max.) simultaneity requirement for touch-/push-button operation
Two mute inputs allow release of actuating buttons during the non-hazardous por-
tion of the machine cycle
Safety Stop Interface (SSI) allows for connection of supplemental safeguards, E-
stop, “Top” stop or anti-repeat devices, or the output of a brake monitor
Description
A DUO-TOUCH SG Two-Hand Control Safety Module may be used with:
Two Banner STB Self-Checking Optical Touch Buttons, each with one normally open and one normally closed relay output contact, or
Two Banner STB Self-Checking Optical Touch Buttons, each with two current-sourcing PNP outputs, or
Two 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 actuating device(s), the Duo-Touch SG relays de-energize, causing the
output contacts to open. The relays will not re-energize until both actuating devices are deactivated and then simultaneously reactivated
(SSI input channels closed).
The Duo-Touch SG Two-Hand Control Kit system has been designed to meet:
Type IIIC requirements of ISO 13851 (EN 574) Safety of Machinery – Two-Hand Control Devices, and
Category 4 requirements of ISO 13849-1 (EN 954-1) Safety of Machinery – Safety-Related Parts of Control Systems – Part 1: Gener-
al Principles of Design
The Safety Module’s output signal consists of four sets of redundant, forced-guided (mechanically linked) contacts (see Figures in Electri-
cal Installation on page 10). 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.
WARNING: Point-of-Operation Guarding
When properly installed, a two-hand control device provides protection only for the hands of the machine
operator. It may be necessary to install additional safeguarding, such as safety light screens, addition-
al two-hand controls, and/or hard guards, to protect all individuals from hazardous machinery.
Failure to properly guard hazardous machinery can result in a dangerous condition which could
lead to serious injury or death.
