If any shortages or damage is noted, please contact the shipping company and/or McMillan Company to resolve the problem. Contents of Box Model 80/80S shown; Model 80D and 80SD have an integrated display. drop Caution: Take care not to your controller. -
Page 4: Product Overview And Principle Of Operation
Flow in the Model 80 Series is controlled by a proportional solenoid valve with active servo electronics. The flow measurement signal is analyzed by micro-processor controlled electronics and compared to a set-point. Adjustments are then made to the valve in order to achieve the required flow rate. -
Page 5: Installation
Installation Caution: Do not exceed the pressure, temperature or power operating ranges detailed in the SPECIFICATIONS section of this manual. McMillan Company shall not be liable for any damage or injury caused by incorrect operation of their products. 1. General Considerations It is recommended that a safety shut-off valve be installed upstream (before) of the controller. -
Page 6: Mounting The Flo-Controller
® 2. Mounting the FLO-CONTROLLER McMillan Model 80 series controllers have no particular orientation or installation requirements so may be mounted in any convenient position. It is recommended that units be fixed to a suitable substrate using the two 4-40 mounting holes provided. -
Page 7: Tubing Connections
When connecting the sensor to the tubing, take care not to over-tighten the fittings or leaking may occur. 4. Installing a McMillan Inline Filter (Optional). An optional 20 Micron Aluminum filter is available for use with the Model 80 series. If ® this is ordered at the same time (recommended) as the FLO-CONTROLLER it will be preinstalled at the factory. -
Page 8: Electrical Connections
Read the following instructions carefully before making any connections. a) Overview The Model 80 Series provides a 0-5VDC analog output proportional to the flow rate. This output may be connected to a display, data acquisition system or voltmeter with an impedance of greater than 2.5 kΩ (kilo ohms). -
Page 9: B) Connecting The 6 Pin Mini Din Connector
(Ground) terminal of the voltage source. Caution: Avoid high voltage static discharges to the input signal connection. Do not short the input/output signal wires or allow them to contact the power wires at any time. DAMAGE WILL RESULT! 80-M001, pg. 9 of 32... -
Page 10: C) Connecting The 6 Pin Mini Din Connector And Cable Assembly
Caution: Avoid high voltage static discharges to the input signal connection. Do not short the input/output signal wires or allow them to contact the power wires at any time. DAMAGE WILL RESULT! 80-M001, pg. 10 of 32... -
Page 11: D) Connections For The 9 Pin D Sub Connector
Pins 1, 5, and 9 are not used. Caution: Avoid high voltage static discharges to the input signal connection. Do not short the input/output signal pins or allow them to contact the power connections at any time. DAMAGE WILL RESULT! 80-M001, pg. 11 of 32... -
Page 12: E) Connections For The 15 Pin D Sub Connector
Pins 3, 4, 6, 9, 11, 12, 13, 14 and 15 are not used. Caution: Avoid high voltage static discharges to the input signal connection. Do not short the output signal pins or allow them to contact the power connections at any time. DAMAGE WILL RESULT! 80-M001, pg. 12 of 32... -
Page 13: F) Using A 0-5Vdc Output / Input Power Adapter Package
An optional 0-5VDC Input / Output Power Adapter Package is available for use with the Model 80 series. This consists of a power source (115VAC or 230VAC), a connection hub and two cable assemblies with pig-tail (soldered wire) ends. This should be assembled as shown in the following diagram. -
Page 14: Operation
At 500sccm the output signal would be 5VDC If the output signal were 3.5VDC then the flow rate would be: 500 ÷ 5 × 3.5 = 350sccm If the maximum flow rate is exceeded non-linear and inaccurate readings will result. 80-M001, pg. 14 of 32... -
Page 15: Changing The Flow Rate Set-Point (From An External Voltage Source)
For a flow range of 0-500sccm (Range 6) : A 5 VDC Input Signal would correspond to a flow rate of 500sccm If a flow rate of 300sccm were required then the set-point would be: (300 ÷ 500) × 5 = 3.0VDC 80-M001, pg. 15 of 32... -
