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.
