Total protection for the two-hand-control system
from “defeat” is not possible. However, the user
is required by OSHA regulations to arrange and
protect hand controls to minimize possibility of
defeat or accidental actuation.
Optical Touch Buttons (OTB or STB series)
may not be used in any environment that
is likely to adversely affect photoelectric
sensing systems. Severe amounts of
contamination, if not controlled or eliminated, may
cause a false ON condition if allowed to block the
sensing beam.

Install
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 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 being used today.
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 (see output ratings, page 6).
STBs must be connected to a type IIIC Two-Hand-Control circuit module, in most cases, when
used to initiate potentially dangerous machine cycles.
Mechanical Installation
OSHA and ANSI require that the hand controls be mounted to pro t ect them from ac c i d en t al or
unintentional operation. Use shields, covers, rings, collars, dividers, or similar protection to pre vent
ac ci den tal switch actuation and to discourage use of forearms or elbows. European standard ISO
13851 (EN 574) includes a detailed discussion of ap proach es to pro tec tion 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.
See ISO 13851 (EN574) Two-Hand Control, ANSI B11.TR1—Ergonomic Guidelines, and EN894—
Safety of Machinery—Ergonomic Requirements—Control Actuators for further information.
Figure 2 shows two methods for mounting the STB Touch Buttons. When mounted on top of the
control bar, the protective field covers should be in place, as shown. For added protection, mount
the STB Touch Buttons sideways under and behind a protective hood, rather than on top of the
bar. This side mount prevents the operator from positioning and leaving an object in the path of the
beam, intentionally bypassing the safeguard.
