    ● INTRODUCTION The T119 DIN is the most advanced unit on the market as regards temperature monitoring units for MV cast resin transformers which utilize PTC sensors. The unit gives the L1 pre-alarm and L2 alarm-trip signals when the temperature limits sensed by the PTCs in the coils are reached.

    If the FAN is set up, the relay activates when the relative PTC sends the first signal and the FAN LED is steady ON: the relay is active for as long as the PTC senses the temperature is normal, the T119 DIN unit keeps the relay ON for the time set during programming and the FAN LED flashes.

    PTC FAN The FAULT +FAN LEDs are flashing ATTENTION If the T119 DIN control unit is not connected to the correct PTC model, the LEDS flash. The PTC temperature is nat + T = 1300 ohm. "PTC" TYPE TEMPERATURE SENSORS The PTCs can be compared to bimetallic thermostats where the contact opens and closes at the approximate temperature, defined as their operating characteristic (NAT=operating temperature).

    The resistance value shown in table 1 refers to a single or multiple series of PTCs. The correct operation of the device is obtained by complying with the stated resistance values. In case the single or multiple series of PTCs have resistance values other than the stated, please contact TECSYSTEM Srl - Technical Service.
