Pinnacle Systems UL-101-2P User Manual

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 t 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.

Troubleshooting System

Red light, but no Green light when Hand inserted into
channel:

A) Excessive Sun or incandescent light over top the

UL-101
B) Conductive grease, or liquid in the channel
C) Proximity of channel to nearby metal objects
D) Did not wait 15 seconds at power-up
E) Heavy gloves may require factory adjustment.

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.

SAFETY DISTANCE FORMULA

Each operator hand control shall be located at a distance from the point of
operation so that the operator cannot release either hand control and reach into the point of
operation prior to die closure or prior to cessation of slide motion during the closing of the
stroke.

Below is the formula for calculating the safety distance of the palm buttons:

The machine should be measured with the machine running at its fastest speed with its heavi­est die or tooling and the stop time being measured at the 90°
position in the down stroke. The following formula should be used when
calculating the safety distance.

Ds = K x (Ts + Tc + Tr + Tbm)

Ds = Minimum safety distance between the device and the nearest point of
operation hazard (in inches).
K = Hand speed constant. This value has been determined by various
studies and although these studies indicate speeds of 63 in./sec. to
over 100 in./sec., they are not conclusive determinations. The
employer should determine this value by considering all factors,
including physical ability of the operator.
Ts = Stop time of the machine tool measured at the final control element.
Tc = Response time of the control system.
Ts & Tc are usually measured by a stop time measurement device.
Tr = Response time of the presence sensing device and its interface, if
any, as stated by the manufacturer or measured by the employer.
Tbm = Additional time allowed for the brake monitor to compensate for
variations in normal stopping time.

Palm buttons used as operator hand controls must be installed in accordance with the instal­lation instructions and applicable local regulations, such as OSHA, ANSI or European stan­dards. The complete machine control system as well as the guarding systems must be con­sidered, including interface, safety distance, ancillary guarding, and all control elements that
affect safety. Consult with your local regulatory agency before installing the palm buttons.

WARNING: DO NOT use on full revolution power presses. This type of press cannot be
stopped in mid-stroke.
