1.9 Functional Overview 1.9.1 General Description The Bacharach Refrigerant Monitor is a portable refrigerant gas monitor. The unit is designed to test for a specific refrigerant gas for the purpose of determining the presence and level of that gas being tested.
Halogen Monitor Operation 2 Operation 2.1 Front Panel Display & Controls 2.2 Connecting Gas-Sample & Exhaust Lines 2.2.1 Overview A single gas-sample line needs to be run from the HM unit to the area to be monitored. An optional purge- air line can also be installed to bring fresh air into the monitor for the purpose of resetting its infrared detector to a baseline of 0 ppm during the purge cycle.
Operation Halogen Monitor 2.2.3 Connecting the Exhaust Line The exhaust line carries the exhausted gas sample away from the monitor, and is required if the monitor is located in a confined, poorly ventilated area. The exhaust line can be up to 50 ft (15.2 m) in length. Ideally this line should terminate outdoors in a location that is not exposed to the elements.
Halogen Monitor Operation The operator can reset the peak value to zero by pressing the ENTER button. The measurement cycle runs for 4 minutes. A log of up to 200 previous measurements can be viewed using the PPM LOG function (page...
Operation Halogen Monitor Tip: If NO button is pressed within 60 seconds the monitor automatically continues with the current TWA/twa. Note: During the time the monitor is OFF, the gas measurement is assumed to be zero and will be factored into the TWA/twa calculation.
Halogen Monitor Operation 2.8.2 Using the Battery The PAGM is designed for a 16VDC input. Following the instructions for the particular battery in use, set the output voltage to 16V. Plug the battery into the instrument's battery input port and the instrument is ready for use.
Operation Halogen Monitor During normal operation, the Data Display screen shows when the monitor is performing the following two functions: MEASURE indicates that the monitor is actively measuring gas. In the screen shown above, 10 ppm of R-134A gas is currently being detected, and that a peak measurement of 20 ppm has occurred sometime in the past.

Operation Halogen Monitor – Used to select one of any of the gas types available for SELECT GAS TYPE monitoring. Factory default is R-134A. Note that the factory can R134A program a custom gas type as specified on the sales order. Use the Keypad to select the desired gas type, and then press ENTER to save the selection and return to the previous screen.
Halogen Monitor Operation The alarm log shows the type of alarm (LEAK, SPILL, or EVAC), plus the date and time it occurred. If CLEAR is displayed, this indicates that an alarm was acknowledged at the date and time shown. Immediately after selecting the ALARMS function, the most recent alarm SPILL @ event is displayed.
Operation Halogen Monitor 2.11.4 Fault Codes FAULT CODES ARE ADDITIVE. For example: A fault code of <0003> indicates that both a Box Temperature Fault <0001> and a Bench Temperature Fault <0002> have occurred. Code Fault Name Description Enclosure temperature is outside normal range (or IR detector has failed).
Halogen Monitor Operation 2.13 The DIAG Function 2.13.1 Overview The DIAG function displays sensor data and status information useful to a service technician for troubleshooting various fault conditions. Explanations of the data shown in these screens are given below. 2.13.2 Keypad Functions From the Data Display screen, press any one of the Keypad buttons to display the first Function Menu screen.
Operation Halogen Monitor 2.14 The Calibration Function If greater than standard accuracy is desired, the factory’s default calibration factor of 1.000 may be adjusted by performing the calibration procedure as described below, and then selecting the monitor’s CAL function to enter the new calibration factor.
2.16 Print/Plot Logged Gas Levels A printout or plot of the last 200 ppm measurements can be made by connecting the optional Bacharach printer and printer cable to the monitor as follows. (Refer to Replacement Parts on page 23 for printer and cable part numbers).
Operation Halogen Monitor 2.17 Downloading Stored Data to a Personal Computer Using the monitor’s PC DUMP feature, the last 200 gas readings that were stored in memory can be downloaded to a personal computer in ASCII text, comma-delimited format, which can then be imported into most spreadsheet programs for analysis.
