  • Page 11 ELECTRICAL CONNECTIONS NOTE: all the useful information on the TRBH system's electrical connections is available in the TRBH SYSTEM manual. NT935BH ETH 1MN0171 REV.0 1) Pt100 sensors (white-red-red) RJ45 Ethernet output, Link-Activity led, see indication on page 30. 2) Power supply 85-260Vac-cc 50/60Hz.
  • Page 12 POWER SUPPLY The NT935BH ETH can be supplied by 85 to 260 Vac-Vdc, 50/60 Hz irrespectively of polarity in Vdc (terminals 40-42). This particularity is obtained thanks to the use of a tested power supply, of new conception and realisation, which frees the installer from any uncertainty regarding the correct Vac or Vdc power supply.

  • Page 15 Pt100 sensors c) damage to the Pt100 inputs of the control unit. TECSYSTEM S.r.l. has designed its own special cable to transfer the measurement signals, CEI-compliant, with all the protection requirements provided for mod. CT-ES NOTE: the use of cables not complying with the above could cause possible reading anomalies.
  • Page 16 Activation of the functions: VOTING (shown below) or FCD (on page 31) in relation to the system conditions. CAL message display: the indication appears when the measurement circuit is damaged. The temperature values displayed might be incorrect. Return the control unit to TECSYSTEM for repairs. VOTING FUNCTION The voting function derives from the redundancy concept that consists in duplicating the components of a system to increase their reliability.

  • Page 18 The ETH module is always in slave mode. The NT935BH ETH control unit is in communication with the network only when it is in temperature reading mode, while it is inactive when in the following modes: display, programming and test relays.
  • Page 19 Trip thresholds and that the Fan-on thresholds must be higher than the Fan-off thresholds. In case you try to set these thresholds incorrectly, the control unit NT935BH ETH will not proceed with the programming and storage of data, therefore in subsequent readings will read the data from the previous schedule.
