The P906C differential pressure controller provides proportional control to maintain the desired pressure difference between two points in a water system. It is suitable for use with modulating control valves to regulate the by-pass differential pressure of water chillers.
Features
• Proportional control
• 4 - 20 mA current output
• Control range: 0 - 70 psi (0 - 483 kPa)
• Adjustable throttling range

Operation
Pressure Difference Adjustment
Because these controllers have such a wide variety of applications, they are adjusted on the job with the system in operation.
IMPORTANT
The device controls the difference between the pressures exerted upon the 2 bellows, not the gauge pressure.
1. Connect a pressure gauge with adequate range to each element assembly.
2. Connect the differential pressure controller and gauges to the pressure points to be controlled.
3. Turn the pressure difference adjustment screw counterclockwise (↖) until the scale indicators reach the low (minimum) end of the scale (Fig. 5).
4. Turn the throttling range adjustment screw until the throttling range indicator is midway between C and D on the throttling scale plate.
NOTE: Do not go beyond the point at which the linkage begins to show slack.
5. Apply typical operating pressures in sequence to the left and right elements (high and low pressure sides, respectively). Turn the pressure difference adjustment screw clockwise (® ) until the desired differential pressure is reached.
6. Adjust the throttling range as needed. To increase the throttling range, turn the throttling range adjustment screw clockwise (® ). To decrease the throttling range, turn the throttling range adjustment screw counterclockwise (↖).
7. Apply pressures through a typical cycle while checking the differential pressure controller operation. Readjust settings if necessary. If there is any indication of short cycling or a hunting condition, increase the throttling range setting.
8. When the system operates as desired, mark the settings on the scaleplate.
