Each actuating device requires a normally open and a normally closed (e.g., Form C or SPDT) hard contact, each capable of reliably
conducting 25 mA at 24V dc (nominal). For complementary PNP operation, model STBVP.. touch buttons must be used to ensure proper
functionality.
Standards require that the actuating devices 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 ISO13851 includes a detailed discussion of approaches to protection of hand controls.
The installation of the hand controls must also consider:
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 ISO13851 (EN574). This standard also recommends that the hand controls be arranged on a horizontal (or nearly
horizontal) surface that is 1,100 mm/43.3" above the floor for ergonomic purposes.
Requirements for Multiple-Operator Control
Standards have specified several conditions for situations where multiple operators work together to control one machine:
It is the user's responsibility to determine if this two-hand control system can be interfaced to the machine in a manner to
satisfy all existing requirements for multiple-operator control.
When installing the hand controls, consider ergonomic
principles, in order to avoid unnecessary user fatigue.
See ISO13851 (EN574) Two-Hand Control, ANSI
B11.TR1 – Ergonomic Guidelines, and EN894, Safety of
Machinery – Ergonomic Requirements – Control Actua-
tors for further information.
The figure shows two examples for mounting Banner’s
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 devices side-
ways under and behind a protective hood, rather than on
top of the bar, leaving the field covers off. This side
mount reduces the possibility of the operator easily posi-
tioning and leaving an object in the path of the beam, in-
tentionally bypassing the safeguard.

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 OSHA reg-
ulations to arrange and protect hand controls to minimize possibility of defeat or accidental actuation.
