Page 3: Introduction
It includes a rugged enclosure, protecting state-of-the-art electronics and will withstand the harsh ambient conditions present in heavy industrial environments. The HMD-SM is used to detect hot metal in a range of temperatures, shapes and sizes of wire, bar, strip, thin plate, thick plate, billet, and slab production facilities. -
Page 4: Specifications
Table 2 2.3 Operating Principle Detector- The HMD-SM uses a Lead Sulfide (PbS) photocell, which is characterized by a very strong signal output for the range of infrared energy emitted by steel, compared with other detector materials. The high signal-to-noise ratio from this detector virtually eliminates detection errors. - Page 5 Figure 2.2: HMD-SM Scanning System Vertical Scanning field- The HMD-SM is manufactured with one of three vertical field angles 10, 30 and 50 degrees, selected at the time of purchase. This enables the sensor to cover the entire process area but not scan beyond the process line where interfering sources of infrared energy may be present.

1. Select the appropriate scanning angle when originally placing order to avoid “over- scanning”. 2. Gradually reduce the sensitivity adjustment on the HMD-SM’s control panel until the background interference is not detected (when no target metal is within the scanning field). -

Purge Air, Cooling Water- The HMD-SM has a water-cooling jacket to cool down sensor temperature and an air-purged shroud for protection of lens; allowing the sensor to be used in harsh environments with high temperatures, steam, dust and smoke. - Page 9 Logika Technologies Inc.

Page 12: Automatic Threshold Level Description
Figure 5.1: HMD-SM Control Panel 5.2 Automatic Threshold Level Description Definition- The HMD-SM includes an Automatic Threshold Level Adjustment. The sensor’s built in circuit will automatically adjust the signal output when hot metal enters scanning field to prevent detect signal from saturation. According to different field applications, base threshold signal level is determined on installation. -

Figure 5.2 HMD Remote Sensitivity Setup and Wiring Diagram 5.4 Test Function To test the electrical integrity of the HMD-SM sensor, follow the steps below: Connect power supply to the HMD-SM, make sure the green LED is ON. Press and hold the “TEST” button when no target in the scanning field of view. -
Page 15: Maintenance
Diagnostics- Usually, the HMD-SM does not need special maintenance. Regular attention to the following will ensure steady operation of the sensor: Lens Cleaning- periodically check the HMD-SM sensor’s glass for dust or oil residue, like a month or 2 months depended on the sensor’s environment and purge air quality. Open the black lens shroud and clean the glass with alcohol and lens paper or soft cloth. -
