TECHNICAL FEATURES AND REGULATIONS TRIGGERING SET POINT Fig. 3, 4 show the case where 6 sensors are applied. S model (standard) The triggering values are reported in fig. 3 and they enable to change over when the sensors reach the temperature VIN and to reset when the VIN temperature is -3°C. L model (large) The triggering values are reported in fig. 4 and they enable to change over when the sensors reach the temperature VIN +10°C, and to reset at the temperature VIN, for allowing the motor cooling. Characteristics of the sensors The PTC sensors are featured by VIN (nominal triggering temperature), that is the temperature value in correspondence of which they increase the value of their resistance. Fig5 shows the frame which must contain the curve R-T of each PTC sensor. Generally the PTC sensors are manufactured with VIN varying from 70°C to 180°C, with steps of 10°C. Fig.6 shows the frame which must contain the curve R-T of 9 PTC sensors in series. If the 9 sensors are equal, VIN value will be the same of the sensors; if the 9 sensors have not the same VIN, the device triggers when at least one sensor overcomes its own VIN, regardless of what is happening to the other sensors. Therefore the device is able to perform a simultaneous control of many points at different temperatures. SETTING: no setting. RESET: automatic. POSITIVE SAFETY The internal relay is normally ON and it goes OFF in case of alarm (fig. 3 and 4). INSTALLATION Follow the wirings as per fig. 2.

FUNCTION AND USE PT 01 detects the temperature increase in the motors (DC or AC) or in parts of machinery, by means of the PTC thermistor As regards the motors, the sensors must be inserted into the windings and serial connected, during the manufacture process. The device is normally used for the direct thermal protection of automatic machines. The parts relevant for the temperature control are: ball bearings, oil, reduction gears, heating elements, heads etc. Such parts can be at different temperatures and different nominal values (VIN) may be required.
