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. 7/09 PAGE 4 - 39
FOR MODELS: JGZ AND JGU SECTION 4 LUBRICATION 2. Days of over and under lubrication. 3. Total oil consumption of compressor lube system 4. Daily and total lost dollars (US) for over lubricating. 5. Total divider block cycles, 6. Total run time of the compressor. The Proflo PF1 monitor can store one year’s worth of operating data in a first in, first out (FIFO) memory. The FFT software can be used to reset Proflo PF1 memory. The reset time and date is recorded to the Proflo PF1's Electrical Erasable Programmable Read Only Memory, (EEPROM). To start the download push the SET button then push the mode button 5 times until the LCD displays SEND DATA? then push the SET button. Set the FFT software to accept the Proflo PF1 data and hold the handheld computer in a position to communicate with the IrDA port. The LCD will display SENDING. If there is no devise to receive the data the LCD will display FAIL- URE and after 30 seconds return to LAST and AVG default display. The software provides for conversion to Microsoft Excel files for trending and graphing. Hand held Palm operating system computers are available at most electronic or discount stores or on the Internet. For more details on this product and other Proflo PF1 accessories, see the Ariel web at www.arielcorp.com and/or contact your packager or Ariel. Proflo PF1 Setup Alarm Time and Mode: To setup the Alarm contact output operation, red wires, first push the SET button. Push mode button six (6) times until LCD displays SETUP?. Push SET button and the LCD will scroll to 1. SET ALARM TIME. Push and release set button to change alarm-shutdown from 30 to 240 seconds. When the compressors leave Ariel this time is set to 120 seconds. Ariel recommends setting the alarm time to 2 times the normal cycle time rounded up to the nearest 5 seconds. This time should not be less than 30 seconds or greater than 180 seconds. Normal design cycle time can be found on a nameplate on the lube oil pump box. The control system must be configured to shutdown the compressor for a no-flow indication. Push the mode button, two (2) more times and the LCD will scroll to SET ALARM MODE. Push set button to toggle from N/O normally open or N/C normally closed. Ariel recommends using the NC operation. After wiring mode is set the monitor will automatically return to the LAST and AVG display in 30 seconds. PAGE 4 - 40 7/09
