Metasys Ventilation Controller Application for the DX-9100 DX-9100 The DX-9100 is a controller manufactured and marketed by Johnson Controls. The Metasys Ventilation Controller Application of the GX-9100 Software Tool is used to program the DX-9100. DX-9100 Hardware The MVC-2000-1 product utilizes one DX-9100. The DX-9100 is factory installed in the MVC-2000-1.
Page 8: Air Valve
Metasys Ventilation Controller The CO sensor is factory mounted and wired in the MVC-2000-1 enclosure. Since it is also factory calibrated, there is no need to calibrate the CO sensor before starting the MVCA. Air Valve Each MVC-2000-1 contains two solenoid air valves. These two V11HGA-100 3-way solenoid air valves switch the input source of sampled air from one of three sampling tubes to the CO sensor.
Page 9: Sample System
Metasys Ventilation Controller Application for the DX-9100 Sample System Figure 2 shows a sample system with an MVC-2000-1 connected to a Metasys Supervisory Controller that supports the DX-9100 via an N2 Bus. The Metasys Supervisory Controller is optional and the workstation is only required for visual trending of data.

Page 11 Metasys Ventilation Controller Application for the DX-9100 • Position: Mount the enclosure vertically. • Air Sampling Locations: Remote or local sensing is acceptable; the outdoor and return air sampling devices can be mounted up to 30.5 m (100 ft) away from the unit. The supply air sampling device can be mounted up to 9.2 m (30 ft) away from the unit.

Metasys Ventilation Controller Procedure Overview Table 2: Using the MVCA with the DX-9100 To Do This Follow These Steps: Install a UPM In a secure location, install the UPM according to procedures listed in the Universal Packaging Module Technical Bulletin (LIT-6363070). Note shock and equipment damage hazards.
Page 13: Detailed Procedures
Metasys Ventilation Controller Application for the DX-9100 Detailed Procedures Installing a UPM To install a UPM: 1. Decide on a location for the enclosure based on the Location Considerations section of this document. 2. Install the MVC-2000-1 enclosure by following the procedures in the Universal Packaging Module Technical Bulletin (LIT-6363070).

Metasys Ventilation Controller 4. For additional maneuvering space during the wiring operation, remove the bottom endcap of the UPM by disconnecting the two assembly screws. 5. Complete the field wiring to the DX-9100. 6. Reassemble the lower UPM endcap. 7. Take care not to pinch any wires. Note: Be aware that in low lighting conditions or cramped spaces, reassembly of the endcap may be difficult.

Page 16: Checking The Solenoid Valves
Metasys Ventilation Controller Checking the Solenoid Valves To check the solenoid valves: 1. Listen to the valves. They produce an audible click when changing states. This should happen approximately every sixty seconds. 2. Time the changes in the valves. Are the solenoid valves changing state in the proper sequence (as detailed in Table 3)? Table 3: Commanded States of Solenoid Valves Relative to Air Sampling Sites...
Page 17: Checking The Controller Application
Metasys Ventilation Controller Application for the DX-9100 Checking the Controller Application Note: Check the controller application to verify that the system remains stable when changing from the ventilation control strategy to the temperature control strategy and that the controller that demands the highest output is in control of the system.
