Why won't my 9900 print the time or date on outside of chart?
 
  1. Chart ran past 12 hours. Follow sticker in door to Stop Chart and Start New chart. This will divert the system.
  2. Verify print head cartridge contains 4 pens. Two and three color cartridges look the same from the front, but do not have all the pens.
  3. Bad print cartridge - replace with new, or test with cartridge from working recorder.
  4. If print arm just replaced, wide blue connector that plugs into motor driver board positioned upside down.
  5. Verify bold scale lines (vertical lines with numbers) start at inner blue ring, and end at outer blue ring. If not, perform chart calibration. Seal needs to be broken - chart cal under Calibration menu.
  6. Faulty print arm assembly - contact Anderson Technical Service

How long does the print cartridge last?
 Typical print cartridge life is two to six months. Time period is dependant on hours per day use, along with the amount of information printed to the chart.

Can't go to forward flow - what should I look for?
  Be sure the timing pump is running. Next, check the front display of the 9900. If set to display, STLR OUT should say ON - if not, you are not above cut-in temperature. If it says ON, you have reached cut-in. Check the flow diversion valve microswitches (shorted, stuck or not alligned). Check for power at the flow diversion micro-switches also - you may have a blown fuse in the 9900 - if this is the case, the legal chart plate seal will need to be broken in order to change. To see the fuse spec go to the 9900 parts page - Click to See

Are the AV-9900 and DART Thermometer probes interchangeable?
 No - although both contain dual 1000ohm elements, the DART probe contains additional circuitry. They are NOT interchangeable.

Can I run the system longer than 12 hours without diverting?
  Yes - at a point prior to reaching a full 12 hour cycle, press the CHART key twice. A menu will appear allowing you to place the unit in HOLD. The rotation will stop, but all legal controls will remain active. The system will not divert as long as you remain above cut-in temperature. Within 5 minutes, you must replace the chart. Press the CHART key twice to return to the menu, and select NEW. A new chart will begin to print, giving another 12 hours of run time. No breaks in data will occur - all data collected while changing the chart will be properly recorded.

My 4-20 current output to my valve does not change. Do I have a bad output board?
 No,you probably don't have a bad output board.Check to see if the controller is in the manual or automatic mode. Section 4. of the AV9900 manual,page 4, 4.3

Can I add cold product record (CPR) or any other option to my existing recorder? Options, hot water control(HWC),flow(SFLR),4-20mA output, relays.
 Yes, you may add any option by obtaining the appropriate input,output,or relay boards, plus an add on kit.Contact Anderson Instrument technical service for a password to change the model number to correspond with the options you have added or removed from the recorder. 9900 Spare Parts
