22. s Note that the sensor output may become slightly negative within the sensor s specifications For example a 5000ppm sensor is still in spec if it is reading 20ppm on pure helium In this case the 4 20mA output would produce 3 94mA Some PLOs indicate a fault under these conditions if you cannot re configure the PLC to avoid this then we would recommend configuring the sensor as a 5 20mA output please contact Analox for details 2 4 RS485 output By connecting to the appropriate terminals see section 2 5 RS485 communications are available with the sensor Using this data from both the CO and O where applicable sensors can be obtained and calibration commands may be sent to the sensor The hardware protocol is 9600 baud 1 start bit 2 stop bits 8 data bits Two wire communications are utilised with the sensor only transmitting in reply to commands from the master Please see Application Note AN 001 for a description of the serial communication protocol with code and message examples 2 5 Internal terminal rail Terminal Function 1 O mV cell positive input 2 O mV cell negative input 3 Earth for cable screens 4 External pressure strain gauge positive supply 5 External pressure strain gauge negative supply 6 External pressure strain gauge positive signal 7 External pressure strain gauge negative signal 8 Earth for cable screen 9 Isolated voltage output
