Minimum 10 cm Minimum Minimum 10 cm 10 cm Minimum 10 cm Enclosure wall Fig. 8 Panel unit rear view Environmental conditions The flow computer should be located in an environment that minimises the effects of heat, vibration, shock and electrical interference. The flow computer should also be installed away from external magnetic fields, such as those generated from electric motors and large transformers.

9. Electrical installation Note: Before actioning any installation observe the 'Safety information' in Section 2. 9.1 Important - please read the following general wiring notes: Every effort has been made during the design of the flow computer to ensure the safety of the user but the following precautions must be followed: 1.
Page 22 12. A disconnecting device (switch or circuit breaker) must be included in the building installation. It must: Have a rating with sufficient breaking capacity. Be in close proximity to the equipment, within easy reach of the operator but not cause difficulty in operating. Disconnect all phase conductors.

Page 26 The quick start commissioning assumes that the M850 will be used with either Spirax Sarco ILVA, Gilflo or M410 (Orifice plate) flowmeters that all use a differential pressure cell. The quickstart guide will show you how to set up the inputs from the DP Cell and pressure and temperature sensors as a stand-alone system only.
Page 27 A grey screen will appear. 'Click' on File / New Settings and select either imperial or metric units. Select units Type in a name that you wish to identify the flowmeter into application A, i.e. Boiler house. 'Click' on 'Configure the installation'.
Page 28 Select 'The flow of steam' and 'Next'. Select the option that you require. To measure saturated steam either a pressure sensor or temperature sensor can be used. If Superheated steam is being measured both pressure and temperature sensors will be required to calculate density compensation.

Page 30 Forward through the next two main application screens. Choose the flowmeter type and size you are using from the drop down menu (ILVA, Gilflo or Orifice flange taps (M410)). Enter the MAX F and V - Z coefficients from the flowmeter calibration certificate supplied with the flowmeter (ILVA and Gilflo).
