Page 3: Basic Requirements And User Safety
User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a 1. BASIC REQUIREMENTS AND USER SAFETY - The manufacturer is not responsible for any damages caused by inappropriate installation, not maintaining the proper technical condition and using the unit against its destination. - Installation should be conducted by qualified personnel . During installation all available safety requirements should be considered. -
Page 4: General Characteristics
User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a 2. GENERAL CHARACTERISTICS The ambient temperature transducer is a basic device of the TRS system (multipoint temperature and humidity measurement system). It is designed particularly to measure temperature (range: -40°C to +85°C) in rooms where food products are manufactured and stored. -

Page 9: Maintenance
User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a An example of the transducers application is multipoint monitoring system (Figure 4.5). Control panel (i.e. SPA-99 made by SIMEX) is used as MASTER in MODBUS network, simultaneously it displays readed informations of all measurement points. -
Page 10: Principle Of Operation
User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a 5. PRINCIPLE OF OPERATION TRS-01a module is equipped with modern digital temperature converter. These IC has resolution of 12 bits. Converted measurement signals are transmitted to the microcontroller where they are computed and filtered according to given parameters. Measurement data can be readed from the module via RS-485 interface by any MASTER controller (i.e. -

Page 12: Transmission Errors Description
User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a 6.3. TRANSMISSION ERRORS DESCRIPTION If an error occurs while write or read of single register, then the device sends an error code according to Modbus RTU specifications (example message no 1). Error codes:... - Page 13 User manual - AMBIENT TEMPERATURE TRANSDUCER TRS-01a a) The answer (we assume that input signal is not out of range): ADDR FUNC BYTE C DATA H,L CRC L,H DATA H, L - measurement value = 255 (25,5°C), no decimal point. Decimal point position can be read from reg.
