Aligning the Sensor With an Alignment Aid The alignment aid is useful for the precise alignment of the retroreflective sensor at long distances. With the alignment aid, it is easier to adjust the visible pilot laser spot, even when the spot is on a retroreflective target that is more than 50 m (160 ft) away. Sight hole Focus screw 1. Mount the sensor. 2. Affix the alignment aid over the laser emitters on the front of the sensor. 3. Activate any item on the Main menu to turn on the pilot laser. 4. Aim the sensor at the reflector. 5. Look into the sight hole from about 50 mm (2 in) away, rotating the barrel as needed. 6. Turn the focus screw located opposite the sight hole to focus the laser spot as sharply as possible. 7. Adjust the sensor or target position until the laser spot is centered on the target. 8. Tighten the mounting screws and recheck the alignment. 9. Remove the alignment aid. While the alignment aid scope is in place, the displayed measurements are inaccurate. The pilot LED is visible only through the sight hole of the alignment aid; the red laser light cannot be seen on the target or another surface. Aligning the Sensor Without an Alignment Aid The measuring (sensing) laser is located where the pilot laser spot is. For fine adjustment, use bracket SMBLT7 with the fine-adjust accessory kit SMBLT7F for an angle of up to ±3° in both X and Y axes. 1. Use the bracket SMBLT7 to mount the sensor. 2. Select any item on the Programming menu and activate it. The pilot laser is on. 3. Hold the retroreflector or target at a short distance. For example less than 1 m (3 ft) and verify that the laser light-spot is centered on it. 4. Move the retroreflector or target to its final position, adjust the position as needed, and verify that the laser light-spot remains centered on it. 5. Tighten the screws of the bracket. Installing the Mounting Brackets SMBLT7 and SMBLT7F These instructions are for the mounting bracket SMBLT7 and the fine-adjust accessory mounting bracket SMBLT7F. 1. Align the pins on the fine-adjust accessory bracket with the holes on the mounting bracket. 2. Bolt the fine-adjust accessory bracket to one or both angles of the mounting bracket. 3. Bolt the mounting bracket onto the mounting surface of the sensor. 4. Loosen the fine-adjust accessory bracket to adjust the laser sensor's alignment with the target. Laser sensor and target are aligned. 5. Tighten all bolts. L-GAGE® LT7 Long-Range Time-of-Flight Laser Sensor 6 www.bannerengineering.com - Tel: +1-763-544-3164 P/N 120244 Rev. C

C

The sensor recalculates the distance measurement every 12 ms. This is not a moving average. A new average is calculated for the previous 12 ms of data. With the SSI output, the data can be read every 1.4 ms (possibly the same reading for 8 or 9 readings, followed by a change). For the most accurate prediction of the target location, take a sample at the 1.4 ms read-rate of the SSI and determine when the change happens. In the worst case, the data is for the average target location and over the previous 12 ms, plus a 1.4 ms delay. For example, the 12 ms average was changed just after the previous read had started. RS422 Protocol RS422 serial interface commands have this structure: <STX><Command><[Data]><EOT>. The sensor responds to the commands in three different ways:

  • <NAK>—The command was not recognized or the data is outside the limit values.
  • <ACK>—The command was recognized and executed. The command requires no response data.
  • <Data>—The command was recognized. The requested data was sent. Definitions STX Start transmission (hex 02 or CTRL B) EOT End of text (hex 04 or CTRL D) NAK No acknowledgement (hex 15 or CTRL U) ACK Acknowledge (hex 06 or CTRL F) Command 3-digit command (ASCII text) [Data] Whole numbers (ASCII text) Note: In ASCII text (Command + [Data]), spaces and uppercase/lowercase letters are ignored. RS422 Cable The RS422 interface is a reliable, serial interface in full duplex mode with transfer rates up to 10 MBaud. The maximum cable length is 1,000 m (4,000 ft). The shielded cable is connected to the sensor connector and the ground terminal of the control cabinet.
