Page 13: Power Supply
POWER SUPPLY The NT511 control unit has 230Vac ±10% 50-60Hz power supply (terminal 36-38). The ground must always be connected to terminal 37. When the unit is supplied directly by the secondary of the transformer to protect, it can be burnt out by strong overvoltages. This happens if the main switch is closed and the transformer has no load (blank test). -

Page 15: 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. -

Page 18: Introduction To The Modbus Inside
RS485 MODBUS OUTPUT (ONLY FOR NT511 MODBUS AND AD) INTRODUCTION TO THE MODBUS INSIDE MODULE The MODBUS INSIDE expansion module is built in the monitoring unit and allows data transfer on a RS485 line with MODBUS RTU protocol, max 32 devices. OPERATING NOTES For the module to work correctly, it is necessary to set the RS485 network set-up parameters: address, baud rate, parity bit. -
Page 19: Function Code
FUNCTION CODE The ModBus module supports the following function codes: - holding register reading (10) - register multiple writing (10) If ModBus receives a message and a CRC error is detected, no answer is given. CODE 3 (10) Request: Slave address, code 3 , Starting address HI, Starting address LO, Number of Point HI, Number of Point LO, Crc LO, Crc HI. -
Page 20: Error Codes
ERROR CODES (exception codes) In case of a wrong request, ModBus will answer with modified codes and codified errors according to the following: - Unsupported function code - Wrong data address - Wrong data (for instance length) POLLING FREQUENCY We recommend polling frequencies equal to or greater than 1 second are adopted. More frequent polling can overload the system without any benefit. - Page 21 Address Address Primary Data HI Data LO Note tables (10) (10) Holding Setting Ch1 register Holding Setting Ch2 register (See note 2) Holding Setting Ch3 register Holding Setting Ch4 register Holding T. max Ch1 register Holding T. max Ch2 register Range 0-200°...

Page 24: Crc Calculation
When the flag is active it means that the fan, even if supplied, is not working because it does not detect the current flowing (presence of no-load voltage). It is assumed that the fan is faulty or improperly connected. CRC CALCULATION The protocol includes 2 CRC-16 bytes in each transmission. - Page 25 The Product purchased is covered by the manufacturer's or seller's warranty at the terms and conditions set forth in the "Tecsystem s.r.l's General Conditions of Sale", available at www.tecsystem.it and / or in the purchase agreement.
