WARNING . . . Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

R58 Expert™ Registration Mark Sensors

Overview

R58 Expert (R58E) sensors offer maintenance-free solid-state reliability for typical color contrasts found in product and material registration applications. Fast 50-microsecond sensing response produces excellent registration repeatability, even in ultra-high-speed applications. This fast response, coupled with the small 1.2 x 3.8 mm (0.05" x 0.15") sensing image, allows the detection of even small and inconspicuous registration marks.

R58E sensors feature TEACH mode sensitivity adjustment by presenting two sensing conditions to the sensor. TEACH mode has two options: Static TEACH and Dynamic TEACH.

Static TEACH is used to position the two sensing conditions individually. Dynamic TEACH provides a means for teaching a series of conditions on-the-fly; the R58E samples the sensing events and automatically sets the switchpoint between the lightest and darkest conditions. The sensor then determines which sensing condition is present for the shortest time and assigns the Output ON condition to that event (therefore, LO/DO selection is automatic). The LO/DO setting can then be reversed in SETUP mode.

The sensor uses a tri-color LED during either teach process and automatically selects a red, green, or blue sensing beam, based on the contrast between the registration mark and its background. For applications where the user wishes to select the sensing beam color, individual colors may be enabled/disabled in SETUP mode.

Sensitivity may be fine-tuned at any time by simply clicking the “+” or “-” buttons on the sensor. The eight-element bargraph display clearly displays the relative received signal strength.

The discrete bipolar (one NPN and one PNP) outputs may be configured in SETUP mode to include a 30-millisecond ON-delay and/or OFF-delay, if required.

TEACH and SETUP configuration may be accomplished either by using the push button on the sensor, or by supplying input pulses via the remote TEACH input. The push buttons may be diabled via the remote input.

The construction of the R58E is extremely robust, with a die-cast metal housing, plastic optics, and IP67 and NEMA 6 leakproof design for harsh sensing environments.

R58 Expert™ Registration Mark Sensors

Sensor Configuration

The R58E is pre-set to power up in RUN mode and sense the most recently taught registration mark. The sensitivity of the R58E may be quickly optimized by using one of two available

TEACH modes: Static TEACH or Dynamic TEACH.

•Static TEACH: Both the Output ON and Output OFF conditions are presented, and sensitivity can be adjusted manually via the push buttons.

•Dynamic TEACH: The registration mark is presented during actual sensing conditions, and the sensitivity can be adjusted manually via the push buttons.

Remote TEACH

The sensor may be configured either via its push buttons, or via a remote switch. Remote configuration also may be used to enter SETUP mode to set ONand OFF-delay, and to disable the push buttons to prevent unauthorized adjustment of the configuration settings. To access this feature, connect the gray wire of the sensor to 0V dc, with a remote switch between the sensor and 0V dc.

Configuration is accomplished by following the sequence of input pulses (see following procedures). The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are defined as “T”:

0.04 seconds ≤ “T” ≤ 0.8 seconds

Static TEACH

In Static TEACH mode, the sensor learns two sensing conditions after each is presented one time. The sensor automatically positions the switchpoint midway between the two conditions. See Figure 3.

NOTE: The sensor will return to RUN mode if either TEACH condition is not registered within

60 seconds. TEACH mode may be cancelled by pressing and holding the Static push button for ≥ 2 seconds. In either case, the sensor will revert to the previous conditions taught (i.e., exit without save).

Static TEACH and Manual Adjust

Sensitivity may be adjusted at any time when the sensor is in RUN mode by clicking the “+” and “-” buttons. Each click translates to 1/2 segment on the signal strength bargraph display. For best sensing reliability, both sensing conditions should register equally distant from the switchpoint on the signal strength bargraph display.
