Banner DUO-TOUCH Run Bar with STB Buttons - Manual (Page 7)

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.
