How to align the DS455Q beam detector.

       

Issue What is the part number for the back up battery for the DS415i and the DS445? Solution The P333 Backup Battery is designed for use with both the DS445 and DS415i Photoelectric Beam Detectors. When using the P333 with the DS415i, the polarity plug in the battery connector must be removed. Pull the white plug out of the connector using a pair of needle nosed pliers before connecting it to the DS415i. When the P333 battery is used with the DS445, there are no modifications necessary.   Part numbers P333, DS445, DS415i  

Issue What is the proper alignment procedure for the DS455Q? Solution  Alignment by LED Apply power to the system. Use the supplied interruption sheets to cover the lower optical modules of the transmitter and the receiver. Look into the upper scope of the transmitter 10 cm (3.9 in.) to 15 cm (5.9 in.) from the optical module. Use the turntable to adjust the horizontal angle. Use the horizontal and vertical adjustment screws to locate the receiver in the center of the viewing area. Look at the Level Meter on the receiver to proceed with fine tuning.  Use a screwdriver to adjust the angle of the upper optical module. As more beam energy is received, each LED status follows this sequence: ON_Flashes quickly_Flashes slowly=>OFF Continue fine tuning until all LEDs turn off. Remove the interruption sheets from the lower optical modules and cover the upper optical modules of the transmitter and the receiver. Repeat the alignment process for the lower optical modules. When all LEDs turn off, the alignment is complete. Remove the interruption sheets from the optical modules. Alignment Using a Voltmeter Apply power to the system. Use the supplied interruption sheets to cover the lower optical modules of the transmitter and the receiver. Insert the voltmeter leads into the alignment check terminals. Set the voltmeter to 10 volts VDC. Use a screwdriver and adjust the upper optical modules to obtain the maximum voltage. In an ideal environment, the voltage is 3.0 VDC or above. Remove the interruption sheets from the lower optical modules and cover the upper optical modules of the transmitter and the receiver. Repeat the alignment process for the lower optical modules. Make sure to remove the interruption sheets and close the covers when alignment is complete.

     

Issue What would cause the Environmental Discrimination Circuit (EDC) activation?   Solution   Something is blocking the beams. Installed on unstable ground. Inappropriate beam power control level. Over the maximum protection range of the model. Soultion: Remove the object. Fix the installation site. Readjust the control level. Reinstall within the maximum range.   Part numbers DS453Q, DS455Q

Issue What would cause a constant alarm violation?   Solution   Something is blocking the beams. Optical modules or covers need cleaning. Optical modules misaligned. Wiring fault. Solution: Remove the object. Clean the optical modules and the covers. Realign. Check wiring.
