    POWER SUPPLY The NT538 ETH control unit can be supplied by 85 to 260 Vac-Vdc, 50/60 Hz irrespectively of polarity in Vdc (terminals 40-42). This is obtained thanks to the use of a tested power supply unit, newly designed and manufactured, that frees installers from worrying about the correct Vac and Vdc supply.

  • Page 14: Programming Notes

    We recommend you check the unit's programming before starting the device. The default parameters set by TECSYSTEM might not match your requirements. Programming the device is the end user's responsibility, the settings of the alarm thresholds and the enabling of the functions described in this manual must be checked (by a specialized engineer) according to the application and features of the system the control unit is installed on.

    / electrical fault of the 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: model CT-ES NOTE: the use of cables not complying with the above might cause reading anomalies.

The temperature values displayed might be incorrect. Return the control unit to TECSYSTEM for repairs. VOTING FUNCTION The voting function is derived from the concept of redundancy which consists of the duplication of components of a system with the intention of increasing reliability.

COOLING FAN CONTROL The unit NT538 ETH has two contacts FAN (FAN1 and FAN2), if properly programmed, can control ON-OFF of fans for cooling system checked. The high flexibility of the NT538 ETH allows you to select, for each channel, an operation mode for contact management of FAN1 and FAN2.

    If WRITE data must always respect the rule T_trip> T_alarm and FAN_ON> FAN_OFF. In case you try to set these thresholds incorrectly, the control unit NT538 ETH will not proceed with the programming and storage of data, therefore in subsequent readings will read the data from the previous schedule.
