Section 2 - Instrumentation For Models: JGH:E:K:T Normally Open and Normally Closed Definition Most electrical components define Normally Open (NO) and Normally Closed (NC) operation as the default state or “on the shelf” state. Example: A NO solenoid valve is open when the coil is not energized, and closed when the coil is energized. A NC solenoid valve is closed when the coil is not energized, and open when the coil is energized. This is not true of DNFT or Proflo electrical contacts. Both the DNFT and Proflo switch contacts are defined as switch states after the divider valve cycles. NO = Normally Open when running; switch is open while the divider valve cycles. This is non-failsafe operation. If a wire falls off while the unit runs, the control system will not alarm/shutdown. NC = Normally Closed when running; switch is closed while the divider valve cycles. This is fail-safe operation. If a wire falls off while the unit runs, the control system will alarm/shutdown. Ariel recommends NC operation. The Proflo is pre-programmed for NC operation. Proflo Installation 1. Loosen the two hex-socket set screws on top of Proflo case and remove magnet housing. Do not remove magnet, spring, and spacer from magnet housing. 2. Remove end plug from desired divider valve. The Proflo installs on either side of any divider valve, but requires the correct magnet housing for each divider valve manufacturer (Trabon, Dropsa, etc.). NOTE: Do not install the Proflo on any divider valves with cycle indicator pins. 3. Verify O-ring is in place on Proflo magnet housing. Screw magnet housing into end of divider valve. Torque magnet housing to 15 foot-pounds max. 4. Slide Proflo all the way onto magnet housing. Torque set screws to 15 inchpounds max. DO NOT over tighten set screws. FIGURE 2-2 Proflo Installation 5. The Proflo LCD indicates cycle time. Verify correct operation by pumping oil through the divider valve assembly. The LCD enables the operator to adjust the lubricator pump for correct cycle time. The force feed lubricator data plate on the lubricator box indicates either normal and breakin cycle times at maximum rated speed, or normal cycle time for applied speed. Use break-in cycle times only for the first 200 hours of operation before changing to the normal cycle time. If unable to determine cycle time, contact the Ariel Response Center. 6. All conduit and connections should be appropriate for area classification. Use flexible conduit to ease installation. Support conduit and fittings to minimize vibration. 7. After Proflo installation or performance of any maintenance on the lube system, compressor cylinders, or packing, pre-lube the complete system with a purge gun to purge air from the divider valves and all components BEFORE COMPRESSOR START-UP.

For Models: JGH:E:K:T Section 2 - Instrumentation the last divider valve cycle time in seconds. AVG is the average time of the last six (6) divider valve cycles in seconds. 2. Push MODE button; the LCD displays NOW, which is current divider valve cycle time in seconds. This mode allows operators to accurately change cycle time by adjusting the force feed lubricator pump. The force feed lubricator data plate on the lubricator box indicates either normal and break-in cycle times at maximum rated speed, or normal cycle time for applied speed. Use breakin cycle times only for the first 200 hours of operation before changing to the normal cycle time. Compressor speed is directly proportional to cycle time; at 50% rated speed, the lube cycle time doubles (see lube sheets in the Ariel Parts Book for table of speeds vs. cycle times). If unable to determine cycle time, contact the Ariel Response Center. 3. Push MODE button again; the LCD displays RUN TIME, which is the total run time of the lube system in hours since the last reset. 4. Push MODE button a third time; the LCD displays CYCLE TOTAL, which is the total divider valve cycles since the last reset. Test Proflo for reliability if CYCLE TOTAL displays over two million. 5. Push MODE button a fourth time; the LCD displays BATTERY - PCNT, which indicates percentage of remaining battery life. If battery voltage drops below safe operating levels the monitor enters ALARM mode. 6. The display mode changes to ALARM when an alarm is triggered. The display defaults to LAST and AVG while the divider valve cycles. To set alarm time and mode: a. Push SET. b. Push MODE six times until LCD displays SETUP?. c. Push SET. The LCD displays SET ALARM TIME. d. Push SET again to display current alarm time. e. Push and release SET button to change alarm-shutdown from 30 to 240 seconds in 5 second increments. Ariel typically sets it to 120 seconds. Ariel recommends setting alarm time to 2 times normal cycle time rounded up to the nearest 5 seconds. Minimum: 30 seconds; maximum 180 seconds. Find normal cycle time on the force feed lubricator data plate. f. Push MODE two more times to scroll the LCD to SET ALARM MODE, which configures the control system to shutdown the compressor for a no-flow indication. Push SET to toggle from N/O (normally open) or N/C (normally closed). Ariel recommends N/C operation. After setting wiring mode, either push MODE two times or simply wait 30 seconds to return to the LAST and AVG display. The Proflo records any setup changes to the EEPROM. Display Errors ALARM - Displays when divider valves are not cycling. Programmed divider valve cycle time has expired. ALARM flashes every 2 seconds during compressor shutdown.To clear alarm, press SET. Alarm will clear and again indicate cycle time upon compressor re-start. OVERLOAD - Indicates a wiring short or circuit switching of too large a load. To correct this, check wiring insulation for bare wires touching ground or each other. Insulate unused wires or re-terminate wires. Self-resetting fuses on the inputs protect Proflo electronics; they auto reset 45 seconds after fixing a short. LOW BATT - Indicates 20% remaining battery life. At 10% remaining battery life, the Proflo shuts down the compressor and flashes ALARM and LOW BATT until batteries are replaced. See battery replacement procedure below. RESET X - Indicates an internal Proflo fault. No alarm displays; the Proflo still counts divider valve cycles and controls inputs and outputs. While the divider valve cycles, the Proflo counts pulses and measures time between divider valve cycles. At 30-minute intervals, the processor writes data stored in memory to on-board EEPROMS. If there is a problem with this, the Proflo issues a Reset error. 3/11 PAGE 2-3
