FAULT 26-28 NC: NO FAULT POWER ON POWER SUPPLY The MM453 control unit has UNIVERSAL power supply, i.e. it can be supplied by 24 to 240 Vac-Vdc, 50/60 Hz irrespec- tively 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. -

Finally switch the unit off and back on to check the memory works correctly, if it is damaged DATA ERROR will be displayed again (send the control unit to Tecsystem srl for repairs). In case of failure of the internal memory, LOST DATA indication appears with the relevant Fault contact (send the control unit to Tecsystem srl for repairs). -

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. 1MN0035 REV. 0 1MN0034 REV. 0 NOTE: the use of cables not complying with the above might cause reading anomalies. It is always important to take into account that any interference on the signal lines might cause anomalies on the Pt100 inputs (CH1-CH2-CH3- CH4......CH24) or on the sensors themselves. -

For a correct working of Modbus it is necessary to load the RS485 network setup parameters: address, baud rate, parity bit (please refer to Modbus parameter programming at page 20). The serial communication of the temperature control monitoring unit is active only when the MM453 is in monitoring mode and not in programming mode. -
