Overview

STB Self-Checking Optical Touch Buttons are touch-activated photoelectric devices designed to replace capacitive touch
switches and mechanical push buttons. Their outputs activate while a finger is in the “touch area” (yoke) of the switch,
interrupting the button’s infrared sensing beam.

Banner STB Series buttons are ergonomically designed to eliminate the hand, wrist, and arm stresses associated with
mechanical push buttons. They require absolutely no physical pressure to operate. LED indicators light when power is on
and outputs are activated.

All models are immune to EMI, RFI, and ambient light interference. STBs have a black polyetherimide upper housing and
yellow PBT base. The 30 mm threaded base on all models provides easy mounting and easy retrofitting into existing
applications. Rugged yellow polypropylene (TP) field covers are supplied with all models to prevent inadvertent switch
actuation due to objects (such as loose clothing or debris) which might accidentally block the sensing beam. The
polypropylene material is capable of absorbing high impact (even at low temperatures) and is highly resistant to abrasion
and to damage by most chemicals.

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, additional 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.

Figure 1. STB Touch Button features

STB Self-Checking Optical Touch Buttons are very similar to the proven and popular OTB Series buttons. The dual­microcontroller internal design of the new buttons, however, allows the hookup to a Banner DUO-TOUCH SG Two-Hand­Control Safety Module, or other two-hand-control designed to meet Type IIIC requirements per ISO 13851 (EN 574)
(requiring 1 normally open and 1 normally closed contact per input channel). These microcontrollers perform a continuous
self-check. The emitter is continuously pulsed, and receiver response is checked accordingly by the microcontrollers. STB
Series Touch Buttons are designed to immediately detect any internal component failure, go into a lockout mode, and
indicate the failure with a flashing green Fault LED.

STB Self-Checking Optical Touch Buttons

The STB outputs are not monitored by the STB circuitry, and have no external device monitoring feedback. Output
monitoring must be accomplished by using an external device, such as a Type IIIC Two-Hand-Control module.

STB Series Touch Button LED Indicators

Power On (green): Solid when power is applied
Output, Fault (green): Solid when button is activated

Off when button is not activated
Flashing when a fault condition is detected

STB Series Self-Checking Touch Buttons were designed primarily to provide the self-checking function required in control­reliable machine cycle initiation applications. STBs also are suitable for use anywhere mechanical push buttons or the
original OTB Touch Buttons are used.

Both the solid-state and relay-output versions have complementary outputs and can be connected to switch power to
equipment as long as the STB’s switching voltage and current limits are not exceeded.

STBs must be connected to a type IIIC Two-Hand-Control circuit module, in most cases, when used to initiate potentially
dangerous machine cycles.

Installation

OSHA and ANSI require that the hand controls be mounted to protect them from accidental or unintentional operation. Use
shields, covers, rings, collars, dividers, or similar protection to prevent accidental switch actuation and to discourage use of
forearms or elbows. European standard ISO 13851 (EN 574) includes a detailed discussion of approaches to protection of
hand controls. The hand controls must be arranged far enough apart so that the operator cannot operate both hand
controls by the use of one arm. Typically, this distance is not less than 550 mm (21.7") in a straight line, but using guards
or alternate mounting arrangement can allow shorter distances, per ISO 13851 (EN574). This standard also recommends
that hand controls be arranged on a horizontal (or nearly horizontal) surface that is 1,100 mm (43.3") above the floor.

Consider ergonomic principles to avoid unnecessary fatigue in the installation of the hand controls. Install the touch
buttons at a height and in a location that will be comfortable for the user.See ISO 13851 (EN574) Two-Hand Control, ANSI
B11.TR1—Ergonomic Guidelines, and EN894— Safety of Machinery—Ergonomic Requirements—Control Actuators for
further information.

The following figure shows two methods for mounting the touch buttons, to prevent accidental switch actuation. When
mounting them on top of the control bar, the protective field covers should be in place, as shown; or for added protection,
mount the touch buttons sideways under and/or behind a protective hood, rather than on top of the bar, removing the
field covers. This side mount prevents an object from being left in the path of the beam, intentionally bypassing the
safeguard. In addition, shields, covers, rings, collars, dividers, or similar protection may be used to prevent accidental
switch actuation.

Figure 2. Protect STB touch buttons to prevent defeat or inadvertent actuation

CAUTION: Install Hand Controls to Prevent Accidental Actuation
Total protection for the two-hand control system from defeat is not possible. However, the user is

required by U.S. and International standards to arrange and protect hand controls to
minimize the possibility of defeat or accidental actuation.

P/N 64136 Rev. C www.bannerengineering.com - tel: [phone]

STB Self-Checking Optical Touch Buttons

CAUTION: Hand Controls
The environment in which hand controls are installed must not adversely affect the means of

actuation. Severe contamination or other environmental influences may cause slow response or false
On conditions of mechanical or ergonomic buttons. This may result in exposure to a hazard.

Two-Hand Control Safety Distance (Minimum Distance)

Both hand controls must be located far enough away from the nearest hazard point that the operator cannot reach the
hazard with a hand or other body part before the hazardous motion ceases. This is the “separation distance” (“safety
distance”), and may be calculated as follows.

WARNING: Location of Touch Button Controls
Hand controls must be mounted a safe distance from moving machine parts, as determined

by the appropriate standard. It must not be possible for the operator or other non-qualified persons
to relocate them. Failure to establish and maintain the required safety distance may result in
serious injury or death.

U.S. Applications

The Safety Distance formula, as provided in ANSI B11.19:
Part-Revolution Clutch Machinery (the machine and its controls allow the machine to stop motion during the

hazardous portion of the machine cycle)

Ds = K x (Ts + Tr + Th)

For Full-Revolution Clutch Machinery (the machine and its controls are designed to complete a full machine cycle)

Ds = K x (Tm + Tr + Th)

in/sec, but may vary between 63 to 100 in/sec based on the application circumstances
not a conclusive determination; consider all factors, including the physical ability of the operator, when
determining the value of K to be used

T

h

the response time of the slowest hand control from the time when a hand disengages that control until the

Th is usually insignificant for purely mechanical switches. However, Th should be considered for safety distance
calculation when using electronic or electromechanical (powered) hand controls. For Banner Self-checking
Touch Buttons (STBs) the response time is 0.02 seconds

T

m

the maximum time (in seconds) the machine takes to cease all motion after it has been tripped. For full
revolution clutch presses with only one engaging point, Tm is equal to the time necessary for one and one-half
revolutions of the crankshaft. For full revolution clutch presses with more than one engaging point, Tm is be
calculated as follows:

Tm = (1/2 + 1/N) x T

cy

N = number of clutch engaging points per revolution
Tcy = time (in seconds) necessary to complete one revolution of the crankshaft

T

r

the response time of the Safety Controller as measured from the time a stop signal from either hand control.
The default Safety Controller response is 0.0xx seconds, plus any additional closed-to-open debounce time. If
the debounce time is adjusted, the time in excess of xx ms (default closed-to-open debounce time) must be
added to the stated response (see Specifications).

T

s

the overall stop time of the machine (in seconds) from the initial stop signal to the final ceasing of all motion,
including stop times of all relevant control elements and measured at maximum machine velocity
Ts is usually measured by a stop-time measuring device. If the specified machine stop time is used, add at
least 20% as a safety factor to account for brake system deterioration. If the stop-time of the two redundant
machine control elements is unequal, the slower of the two times must be used for calculating the separation
distance

European Applications

The Minimum Distance Formula, as provided in ISO 13855:

S = (K x T) + C

S

the Minimum Distance (in millimeters)

K

the ISO 13855 recommended hand-speed constant (in millimeters per second), in most cases is calculated at
1600 mm/sec, but may vary between 1600 to 2500 mm/sec based on the application circumstances
not a conclusive determination; consider all factors, including the physical ability of the operator, when
determining the value of K to be used.

T

the overall machine stopping response time (in seconds), from the physical initiation of the safety device to the
final ceasing of all motion

C

the added distance due to the depth penetration factor equals 250 mm, per ISO 13855. The ISO 13855 C
factor may be reduced to 0 if the risk of encroachment is eliminated, but the safety distance must always be
100 mm or greater

Example Separation Distance Calculation

The following example illustrates the use of the formula to calculate separation distance for a part-revolution clutch
machine. This example uses 0.50 seconds as a typical value for Ts and 0.035 seconds for Tr and 0.020 seconds for Th:

WARNING:

Safety Systems Used for Two-Hand-Control. In a two-hand-control/trip system that incorporates STB
Touch Buttons as the actuation devices and functions as a safeguard, the anti-tiedown and simultaneity
monitoring functions should not be performed by a nonsafety-related device (e.g., a PLC or PC). Per
OSHA 29CFR1910.211(d)(62), the “safety system must...operate together as a unit, such that a single
failure or single operating error will not cause injury to personnel due to point-of-operation hazards.”

Refer to the appropriate standard to determine the requirements of a two hand-control/trip system
when used for safeguarding.
