SECTION 6 MAINTENANCE:
6.1 Position System
The HDI 2200 is a digital electronic gauge designed specifically for Oilfield applications. The
system is easily calibrated while at Open and Close respective position and can be completed
within minutes if Minor Adjustments are required. Generally, this system should only require
calibration every 2 years when the power pack is replaced or if there are any change in system
wiring or if a repair is completed. One (1) to two (2) hours per gauge should be allocated if a
potentiometer needs to be replaced allowing the unit to be removed from the choke body,
repaired and then calibrated to the LCD.
6.2 Position Systems Battery Replacement:
Remove the Canon Connector from the back side of the case. Remove the four (4) 1/4"-20 hex
screws, nuts and washers and remove the unit from the panel. Remove the 10 8x32 flat head
phillips screws from the front of the unit. Remove the front plate, trim ring plexiglass and gasket.
Be careful not to damage the gasket. Lay the gauge to the side and assure it does not get
damaged. The battery is secured by velcro to the case. Pull apart the connector that connects
the battery to the display. A large screwdriver may be used by carefully placing it under the battery
to pry it out of the case. Insert the new battery in the case to the velcro. Reconnect the connectors.
It is suggested that you replace the desiccant pack, corrosion inhibitor and humidity indicator at
this time. Reassemble the display which has the HDI 013 processor board assembly as one piece.
If possible, it is suggested that you Test the System to ensure everything is working before closing
up the gauge. You may connect the connector to the case and have the choke bodies functioned
to calibrate the unit per Section V. If the system operates properly, reassemble and remounte in
the reverse order. Connect the canon connector to the rear of the case prior to securing the LCD
to your panel. Check Calibration as a precaution. Note: the Power pack is covered under a 1
year warranty from date of shipment and will generally last you 18-24 months. When not in use,
it is suggested to power off the unit to extend battery life.
