Pinnacle Systems UltraTouch UL-101-2P 24VDC User Manual
Models
Models:
UL-101-2P (2 pole, 24VDC)
UL-101-4P (4 pole, 24VDC)
Installation
UltraTouch must be installed in pairs with an anti-tie down
circuit between them to force the user to activate both units
concurrently to initiate hazardous motion. Install units in
such a manner that the wrist or forearm cannot activate
both units while reaching into the point of operation. They
shall be located a minimum of 25” apart, center to center.
Install both units the proper distance away from the point of
operation in accordance with OSHA regulations.
WARNING: Do not over-tighten the four hold down
screws (diagram item #12). Tighten unit on top of gasket
to obtain a snug fit and no more.
WARNING: This unit does not contain anti-tie-down
circuitry. This function is performed either by a UL-601
unit or your own control system. This is an initiation
device only and not a safety device.
Operation
Each UltraTouch contains an optical sensor, capacitive
sensor and circuitry that requires the user to activate both
sensors within a 1/4 sec of each other. When you insert
your hand into the slot, (1) you break the infrared beam,
and (2) your mass is detected by the capacitive sensor (this
dual sensor system prevents accidental activation of the unit
due to shirt sleeves, etc.) The Green LED will light and the
relay(s) will energize.
