Important Application Information
Prevention of False Actuation
Any anti-tiedown control must be designed to prevent accidental actuation. Anti-tiedown circutry must be designed to ignore false
input signals. False signals include (but are not limited to) voltage transients, contact "bounce", and EMI or RFI "noise". If a PLC
or any other solid-state controller is used to provide anti-tiedown, the design must assure that short duration signals (typically any
signals less than a few milliseconds) are ignored. There are several manufacturers of anti-tiedown logic modules which include
circuitry to minimize the possibility of false actuation.
Definitions:
Two-hand Trip (Control): A control that requires the operation of two separate control actuating devices by a machine operator's
hands for initiation of a machine cycle.
Anti-tiedown (Control): A two-hand trip control configured so that both of the operator's hands must be removed and then
reapplied to the control actuating devices to start another machine cycle. (Also called "anti-defeat" control.)

Ordering Information:
OPTO-TOUCH Optical Touch Buttons are shipped with a black field cover, as standard. A black field
cover will be received if the OPTO-TOUCH is ordered by its model number (only). Red, yellow, or green field cover may be specified instead by
ordering the OPTO-TOUCH using the appropriate 5-digit part number from the table, below. Field covers may also be ordered separately (page 3).
