Product: STB Self-Checking Optical Touch Buttons

Directive: Machinery Directive 2006/42/EC

Representative in EU: Peter Mertens, Managing Director, Banner Engineering BV. Address: Park Lane, Culliganlaan 2F, bus 3,1831 Diegem, Belgium.

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 installed on 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:

• Use adequate point-of-operation guarding
• Failure to properly guard hazardous machinery can result in a dangerous condition that could lead to serious injury or death.
• When properly installed, a two-hand control safety device provides protection only for the hands of the machine operator. It might be necessary to install additional safeguarding, such as safety light curtains, additional two-hand controls, and/or hard guards, to protect all individuals from hazardous machinery.

STB Self-Checking Optical Touch Buttons are very similar to the proven and popular OTB Series buttons. The dual-microcontroller internal design of the new buttons, however, allows the hookup to a Banner DUO-TOUCH SG Two-Hand- Control 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.
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 control-reliable 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. Protective field covers are installed 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) 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 in) 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.
Banner Engineering also manufactures runbars with STB buttons installed, see p/n 131634 for more information.

CAUTION:

• Install hand controls to prevent accidental actuation
• It is not possible to completely protect the two-hand control system from defeat.
• OSHA regulations require the user to arrange and protect hand controls to minimize possibility of defeat or accidental actuation.

CAUTION:

• Avoid installing hand controls in contaminated environments—Severe contamination or other environmental influences could cause a slow response or false on condition of mechanical or ergonomic buttons.
• A slow response or false on condition could result in exposure to a hazard.
• The environment in which hand controls are installed must not adversely affect the means of actuation.

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:

• Mount hand controls at a safe distance from moving machine parts
• Failure to establish and maintain the safety distance (minimum distance) could result in serious injury or death.
• Mount hand controls as determined by the applicable standard. The operator or other non-qualified persons must not be able to relocate the hand controls.

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)

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

the Safety Distance (in inches)

the OSHA/ANSI recommended hand-speed constant (in inches per second), in most cases is calculated at 63 in/s, but may vary between 63 in/s to 100 in/s 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.

the response time of the slowest hand control from the time when a hand disengages that control until the switch opens;
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.

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 calculated as follows:

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

the response time of the Safety Controller as measured from the time a stop signal from either hand control is received. The Safety Controller response time is obtained from the Configuration Summary tab in the Software.

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 EN 13855:

the Minimum Distance (in millimeters) the EN 13855 recommended hand-speed constant (in millimeters per second), in most cases is calculated at 1600 mm/s, but may vary between 1600 mm/s to 2500 mm/s 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.
the overall machine stopping response time (in seconds), from the physical initiation of the safety device to the final ceasing of all motion.

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:

• K = 63 in per second,
• Ts = 0.50 seconds (measured by a stop-time measuring device) Tr = 0.035 seconds
• Th = 0.020 seconds
• Ds = K × (Ts + Tr + Th)
  = 63 in (0.50 + 0.035 + 0.020)
  = 35 in

In this example, both hand controls must be located no closer than 35 in from the nearest hazard point.

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 (for example, 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.
