Section 2 - Instrumentation For Models: JGH:E:K:T 1. RESET 1 - Proflo processor unable to determine if the EEPROM contains valid configuration information. Reset 1 usually occurs after a RESET 3 occurs. Upon reboot, the Proflo loses stored and configuration data; programmed information must be reentered. 2. RESET 2 - Proflo processor unable to determine storage of any data or location for next data. Upon reboot, the Proflo loses stored data, but retains configuration data; programmed information need not be reentered. 3. RESET 3 - Internal Proflo fault. The Proflo processor tried and failed three resets. The most likely cause is failure to write to the EEPROM. To try to correct the problem: a. Remove Proflo batteries. b. Press SET button for 45 seconds to discharge internal capacitors and ensure a complete reset. c. Re-insert batteries to reboot the Proflo. • If the error was a one-time problem, the Proflo reboots as normal. • If diagnostics detect an error on reboot, the Proflo displays a constant RESET error again. Replace the Proflo and contact Ariel Corporation. Sometimes on reboot, the Proflo flashes RESET. This is normal. NOTE: Moisture on Proflo circuitry causes most reset errors. Several design precautions keep moisture from the circuit board: • The Proflo housing is completely sealed in a low humidity room. • There is a desiccant pack in the circuit board chamber. • The circuit boards have a protective conformal coating. Proflo Battery Replacement The Proflo formerly used alkaline batteries. Sometimes, alkaline batteries leak, release acid, and corrode the battery compartment, and their service potential diminishes at extreme temperatures. The Proflo now uses Lithium batteries, which provide superior leakage resistance, greater service advantage at temperature extremes, and longer shelf and service life. Ariel highly recommends AA Energizer Lithium/FeS2, model L91 batteries to reduce maintenance costs. This is a true Lithium battery, unlike several other brands. While not recommended, use replacement alkaline batteries only when Lithium batteries are unavailable. Component damage due to battery leakage is not normally covered under warranty. Front cover removal voids the warranty, except on older Proflo monitors made prior to 3/2003 where batteries may be located under the front cover. CAUTION: Explosion hazard! Disconnect/lockout electrical power to control circuits before battery cover removal. Power connected to the Proflo presents a potential of fire, electrical shock, personal injury, or death. Change batteries only in a non-hazardous area. Earlier Proflo models use a front battery access cover while later models use a rear access cover to reduce potential risk. Disconnect power to Proflo to replace batteries regardless of battery access location PAGE 2-4 3/11
For Models: JGH:E:K:T Section 2 - Instrumentation 1. Remove the six battery cover screws. Battery Compartment 2. Remove battery cover and gasket. Cover with Gasket 3. Remove old batteries. Remove plastic protective sleeves from old batteries. Save the sleeves and discard the old batteries in a responsible manner. Two AA Energizer Lithium L91 Batteries with Plastic Protective Sleeves - + 4. Press SET for 45-60 seconds without batteries installed to dissipate stored energy and allow the Battery Cover Screw battery display to update immediately after new battery installation. This step is optional; the monitor automatically updates the battery display within 30 Battery Clips + - minutes of operation. FIGURE 2-3 Proflo 5. The outer cover of batteries is the positive terminal; verify it is unscratched. If a scratched outer cover touches the metal battery holder, the battery depletes Rear Battery Compartment 6. very quickly and the Proflo displays LOW BATT. It is possible for one battery to completely deplete and the other to reverse polarity. Replace with new unscratched batteries if this occurs. Slide the plastic protective sleeves onto the new batteries and insert new batteries into the battery holder. The plastic sleeves and the gasket on the bottom of the cover ensure a tight battery fit. Compressor vibration can cause premature failure in batteries not installed tightly. Verify the batteries are installed with correct negative/positive orientation. Do not scratch or damage new battery outer covers during installation. 7. Re-assemble cover, gasket, and screws. The cover holes align with the six monitor body holes in only one direction; verify correct installation. Installing the cover upside down results in stripped screw threads and compromises the battery compartment seal. Do not over-tighten the screws. Replace lost cover screws with 4-40 x 3/16 in. pan head machine screws. 8. Press SET once, then press MODE until the LCD displays BATTERY. If stored energy was dissipated (see step 4), the monitor checks battery voltage, resets, and displays remaining battery power. The monitor automatically searches for battery voltage at the next 30 minute read/write interval and updates to the new battery power percentage. All trending and configuration data store in the Proflo EEPROM. Battery failure or replacement causes no memory loss. 3/11 PAGE 2-5
