Heavy Duty Balanced Opposed Compressors - Ariel Corporation

FOR MODELS: JGZ AND JGU SECTION 4 LUBRICATION
NOTE: TO SWITCH TO 120/240 VAC LOAD USING THE PROFLO PF1 OUTPUTS, A
RELAY INTERFACE MUST BE USED. SEE “Proflo PF1 Accessories Available:”
ON PAGE 4-47.
Proflo PF1 Button Operation:
Following is a description of how an operator can use the Proflo PF1 buttons.
1. First push set button on the front of the monitor box housing to clear ALARM and
the LCD will display LAST and AVG. When this is done the alarm output contact
will go to the as running state. If the operation is set to NC then the output alarm
contact will close.
LAST is the last divider block cycle time in seconds.
AVG is the average time of the last six (6) divider block cycles in seconds.
2. Push the mode button once and the LCD will display NOW.
NOW is the current divider block cycle time in seconds.
This mode allows the operator to accurately change the cycle time by adjusting
the force feed lubricator pump. Break-in and normal lube timing in seconds per
cycle is given on the force feed lubricator data plate on the lubricator box at maximum
rated speed, based on the gas operating conditions provided to Ariel (or
clean, dry 0.65 S.G. sweet natural gas, rated speed and discharge pressures if no
conditions were provided), when plate was installed. At reduced compressor
speeds cycle time may be increased in a directly proportional relationship. At
50% rated speed the lube cycle time is doubled (see lube sheets provided in the
Ariel Parts Manual for table of speeds vs. cycle timing).
3. Push the mode button again and the LCD will display RUN TIME.
RUN TIME is the total run time of the lube system in hours since the last reset.
4. Push the mode button a third time and the LCD will display CYCLE TOTAL.
CYCLE TOTAL is the total divider block cycles since the last reset.
5. Push the mode button a fourth time and the LCD will display BATTERY - PCNT If
battery voltage drops below safe operating levels the monitor will go into ALARM
mode.
BATTERY - PCNT indicates percent of remaining battery life.
The display mode will change to alarm when the Proflo PF1 goes into alarm. The display will
default to LAST and AVG display when the divider block is cycling.
Downloading Proflo PF1 Data:
A hand held Palm operating system computer equipped with an infrared (IrDA) port and running
Palm Operating System can be used to interface with the Proflo PF1. CCT Incorporated,
Fluid Flow Trending (FFT) software can be used to download operating data. Using this feature
is not essential for compressor operation, but recommended for evaluating the force feed lube
operation and reducing operating costs. See “Proflo PF1 Accessories Available:” on page 4-
47, for more info on the FFT software. The following information may be obtained:
1. Oil consumption for each 30-minute interval, of compressor operation.
