Page 5: Safety Notes And Recommendations
3. The air supply must be turned off before carrying out any work on the pneumatic system. 4. The air supply must not exceed that specified on the instrument or in the Test Certificate. 5. If in doubt about any aspect of safety with the equipment then contact Furness Controls BEFORE proceeding. -
Page 6: Introduction
The output can be scaled as a linear or rooted function to facilitate the use of Pitot Static Tubes or other primary flow elements. The FCO432 is suitable for industrial applications of control, measurement and monitoring. -
Page 7: Installation
Installation Mounting The recommended mounting position of the FCO432 is with the pressure entry ports facing directly downwards. This helps prevent the ingress of dust and liquid. Due to the sensitivity of lower range instruments, they should not be mounted in areas where they will be subjected to high vibration as this could cause spurious readings. -
Page 8: Electrical
Electrical The FCO432 is fitted with a M12 connector as standard. See the “Alternative electrical connections” section at the end of this user guide for non-standard connector information. M12 (5-Pole) Electrical Connection Connector type: 5-Pole M12 female, Code A, shielded, straight, field installable connector with screw terminals and a PG9 cable gland (suitable for cable Ø4 to Ø8mmOD). - Page 9 Connector wiring Assembly Note Housing alignment tabs must be fitted into the plastic locating slots and not the electrical terminals FCO432 Users Guide Issue 1 Page 9...
- Page 10 Connector type: 5-Pole M12 female, Code B, straight, field installable connector with screw terminals and a PG9 cable gland (suitable for cable Ø4 to Ø8mmOD). The FCO432 can incorporate a pair of relays for triggering auxiliary equipment such as alarms. Note the relays are supplied from the +24V on the power connector.

Installation USB-B Connection The FCO432 is fitted with a Micro USB-B connector on the main circuit board and can be fitted with an optional external USB-B port. USB drivers and support tools are available on the Furness Controls product CD (\Drivers\USB drivers) or may be downloaded from http://www.furness-controls.com/filelist. - Page 13 The write settings tab allows the settings to be saved to text (.txt) file and formatted with each heading and the setting that has been applied to it. The Write settings button will save all the Transmitter settings under the headings from the 400 Series firmware menu. FCO432 Users Guide Issue 1 Page 13...

Page 23: Error Messages
Error Messages The FCO432 displays an error number, followed by a description of the error. The description is scrolled across the display after a short delay. Error 0 EEPROM calibration data error Calibration data stored in the EEPROM may have become corrupted. -
Page 24: Calibration
Calibration Furness Controls recommend that all pressure transmitters and flow devices are recalibrated annually. For critical applications, it is advisable to check the calibration more frequently. All calibration adjustments of 400 series pressure transmitters are performed through a PC using the FCS541 Utility software/cable or using the optional keypad. -

The Mid button sets the output to the mid-point value (e.g. 12mA). The Maximum button sets the output to the maximum value (e.g. 20mA). The Reset button immediately cancels test mode and returns the output to normal. FCO432 Users Guide Issue 1 Page 25... -
