INTRODUCTION
The 50-HERK2 is an advanced planar microwave motion sensor designed
for commercial doors and gates. The sensor can differentiate between
people and vehicles. Its two relay outputs can be programmed
independently for a multitude of applications. Additional features include
cross-traffic optimization and slow-motion detection.

MICROWAVE MOTION SENSOR
for Commercial Doors
Failure to follow these safety precautions may cause DAMAGE to
sensor or objects, SERIOUS PERSONAL INJURY, or DEATH.
• This product is designed to be mounted above an overhead
commercial door.
• DO NOT use this product other than for its specified application.
• Observe ALL applicable local, national, and international door safety
standards, codes, and laws.
• ONLY trained and qualified personnel may install and initialize the
sensor.
• ONLY authorized factory personnel may perform hardware/software
changes or repairs to the product.
• The sensor should ONLY be operated from a safety extra low
voltage (SELV) system with safe electrical separation.
• ALWAYS consider the safety functions of your applications as a
whole, NEVER just in relation to one individual section of the
system.
• The installer is responsible for testing the system to ensure it
meets ALL applicable safety standards (e.g. UL 325).
• NEVER touch ANY electronic components or lenses.
• After accessing the inside of the sensor, ensure the cover/
protection seal is closed tightly to achieve designated protection
rating.
• ENSURE the commercial door operator has ALL of its monitored
entrapment protection devices installed and operational. This
sensor does NOT replace any entrapment protection devices.

ADJUSTMENT INCLINATION ANGLE TILT ANGLE It may be necessary to tilt the sensor for certain applications (not After installation, adjust the inclination angle to the desired detection pattern. Adjust the inclination angle by loosening the hand-screws on the recommended unless warranted by special circumstances). Loosen the sides of the sensor and adjusting as shown below. -

PROGRAMMING - WITHOUT REMOTE CONTROL SENSOR FUNCTIONS Several crucial functions can be programmed with the buttons on the sensor. All remaining functions must be configured by the 50-HERK-RC2 remote control (not provided). 1. Remove the screws from the front cover and remove the front cover to locate the LEFT L and RIGHT R buttons. -
Page 5: Remote Control Power
PROGRAMMING - WITHOUT REMOTE CONTROL WIDE FIELD SENSING To use wide field sensing, the clip MUST be installed on the front of the microwave planar module and the wide field setting turned to ON. The sensor will not function correctly if the clip is installed and the wide field setting is set to OFF. The wide field setting is only available for mounting heights up to 13' (4 m). - Page 6 PROGRAMMING - WITH REMOTE CONTROL (NOT PROVIDED) If unable to enter programming mode with the remote control or no access code is set, use one of the alternate methods: Enter programming mode (OPTION 2): Restart the sensor (temporarily disconnect the power supply). Programming mode is activated when the sensor is switched on. Enter programming mode (OPTION 3): Remove the screws from the front cover and remove the front cover.

Page 8: Troubleshooting
TROUBLESHOOTING SYMPTOM SOLUTION People/vehicle separation does not work as expected Check mounting height and setting (more than 10' [3 m] is recommended) Check mounting situation and environment (sensor centered above door is best) Check setting/clip for wide field pattern Late detection of traffic Increase field size/sensitivity Adjust inclination angle to move the pattern away from the door Door reverses (sensor reacts to closing door)
