TECHNICAL FEATURES AND REGULATIONS SP1 (triggering set point) The set point 1 is regulated by the multiturn trimmer SP1 on the front and it is displayed by turning the switch CO in position SP1. SP2 (reset set point) The set point 2 is regulated by the trimmer SP2 on the front and it is displayed by turning the switch CO in position SP2. SP2 must be lower than SP1. If by mistake SP2 is set at a value higher than SP1. the led E starts blinking. SP3 (safety set point) The set point 3 is regulated by the trimmer SP3 on the front and it is displayed by turning the switch CO in position SP3. This set point has a 3% hysteresis. CO When CO is in position T, the actual temperature value is displayed. In the positions SP1, SP2 and SP3, the correspondent set points are displayed. VISUALIZATIONS Display with red leds for the tempera- ture (T) and the set points. LED A: it lights on when T overcomes SP1 and it lights off when T returns below SP2. LED E: it blinks when SP2 is higher than SP1 (wrong condition). LED B: it lights on when T overcomes SP3. OVERFLOW (or broken sensor): Display : OFF, Led A and B are ON. DISPLAY: 3 digits, 7 segments 12,5 mm “high efficiency” THERMAL DRIFT: 50 ppM/°C ACCURACY: ±1% (fs), ±digit MODE OF OPERATION See fig. 1.
