1. Introduction SDIS is universal configurable sensor for the detection of hot metal and its position. For its versatility can sensor operate as a hot metal detector (responds to the presence of hot material), or as a loop scanner (determines the position of the material in the field of view). Main advantages of SDIS are high speed scanning, comfortable and easy setting and displaying parameters using the push buttons and display on the unit or remote (RS232, RS485), wide set of options, two independent sets of detection parameters and switching between them (also...
HMD - hot metal detector - a device only detects the exceeding signal amplitude of photocells over the set threshold. It does not matter if the field of view of the sensor is an edge of the material. It is necessary to limit field of view (depending on site conditions) by the appropriate mechanical shutters or cover.

4. The mounting and wiring 4.1. Location The distance between the SDIS and the measured product is not critical and depends on the scanning angle so as to cover the entire measurement field. Measured product may not fill the entire sensor field of view. Just intersects only a portion of 1 cm ² at a distance of 4 m sensor The optimal distance between the sensor and the various types of materials are as follows: Material Distance between product and sensor...

The buttons have their numerical meanings: [↑] = 1 [←] = 2 [→] = 3 [↲] = 4, then confirm PIN by [↲]. There are two levels of user privileges to change the settings: Basic - for change the most important parameters- PIN: 3412 Advanced - for adaptation of the sensor on actual measuring site - PIN: 2314 - includes all items of the main menu (PIN: 3412)

Window – measuring window configuration For position measurement there is possibility to adjust measuring window - e.g. narrow max. field of view range or adjust start and end limits for analog output signals 4 - 20 mA (menu items Beg and End), and adjust hysteresis to eliminate signal bouncing at the edges of measuring window (menu items HysB and HysE).
