    MSDS and take appropriate precautions when performing maintenance on the gas cell. Most of the time, the ACM 150 monitor operates, sampling ambient air without toxins. In the event of a toxic gas release at one of the sample points for the monitor, small amounts of poisonous gas and residue may be trapped inside the sample tubing, filters, and pumps inside the monitor.

    The user must provide a circuit breaker for the main power supply per local electrical codes. 2.10. Hazardous Energy Isolation The ACM 150 monitor uses high-pressure CDA (compressed clean, dry air up to 100 psig) and low-pressure (5 psig) nitrogen. Both energies may be stored inside the monitor and must be relieved before performing any maintenance work involving the pneumatics.

  • Page 19: Compressed Air Isolation

    ACM 150 2.10.1. Compressed Air Isolation Compressed air can be isolated by ensuring that the ACM 150 monitor compressed air isolation valves for the supply have been installed during installation or setup. Since each site’s requirements vary, it is up to the end-user to provide this isolation. Compressed air- stored energy can be removed by shutting off the air supply and allowing the pressure to bleed.

  • Page 26: Main Power Switch

    ACM 150 3.2.2. Main power switch This switch controls the line power. The ACM 150 monitor cannot operate unless it is switched ON. Switching it OFF disconnects line power to all ACM 150 assemblies. This is also a Lockout/Tagout (LOTO) switch. It accepts an external padlock in the OFF position.

  • Page 27: Sample Valve Control Panel

    Each area number is also a momentary test switch, which may be pressed and used for test purposes when the ACM 150 monitor is in the Front Panel Mode. In other modes, the switches are inactive.

  • Page 28: Control Panel Status

    To perform correctly, check valves must be installed in the sample lines connected to the ACM 150 monitor for the Line Leak Test to perform appropriately. This feature may be disabled via the configuration software.

  • Page 29: Cycle Valves

    ACM 150 3.2.6. Cycle valves When the computer selects a sample area, the corresponding sample valve diverts the flow path from bypass to sample. The boost pump draws the air sample in and pumps it to the gas cell connected to the boost pump through the cycle valve assembly.

  • Page 32: Pump Assemblies

    3.2.8.1. Venturi Pumps The ACM 150 monitor has two air-driven ducts (venturi pumps). One is the Bypass Venturi Pump. It draws a constant airflow through the tubes and the sample valves. This flow is only interrupted when the sample valve is energized, i.e., when the ACM is sampling that area.

  • Page 33: Figure 12. Mechanical Pump Assembly

    3.2.8.2. Mechanical pumps The pumps are isolated in the bottom section of the ACM 150 monitor to muffle the noise and isolate vibration. Heat—cooling fans in the bottom section of the cabinet direct airflow across the pumps and their motors. The pumps are accessed by removing the front panel.

  • Page 47: Other Sampling Components

    3.4.6.4. In-line sample filters Honeywell supplies the initial set of inline filters for each sample port on the ACM 150 monitor (from 10 to 40). The filters are installed near the sample inlet. They prevent a build-up of particulates in the tubes and protect the flow control orifices in the Sample Valves.

    The following options can be included with or added to any ACM 150. 3.5.1. Sample points The ACM 150 monitor can be purchased with 10, 20, 30, or 40 sample points. There is a maximum of 40 sample points. 3.5.2. Automatic line leak test Sample tube integrity must be confirmed whenever a new tube is installed.

  • Page 49: Acm 150 Operating Principle

    The ACM 150 monitor can provide qualitative identification and quantitative analysis of the chemicals in their gaseous state. Each time the ACM 150 monitor scans an air sample, it collects multiple spectra of that sample, typically 4 or 2. The FTIR spectrometer takes about 1.2 seconds to collect a single scan.

  • Page 50: Permanent Calibration

    Calibrations taken on one ACM 150 must be valid for computing accurate concentrations on any other ACM 150. In that way, calibration spectra are also valid for all ACM 150s and older models. This is accomplished using a reference (or background) spectrum to which each analysis spectrum is ratioed.

  • Page 51: Analytical Methods

    The computation accuracy is further improved using advanced data fitting statistical techniques, known by the broader term of Chemometrics. The technique of PLS (partial least squares) is employed in the ACM 150 monitor to fit a data set from the unknown air spectra to the “training” set in the method.

  • Page 52: Zpd Values (Zpd Energy And Zpd Position)

    3.6.5.2. Your Methods - Chemicals Monitored by Your ACM 150 The ACM 150 monitors the air samples for the presence of gases and vapors of liquid chemicals. It will monitor only those chemicals for which it has been configured. Although several methods may be used, the ACM 150 monitor is always provided with at least one analytical method.

  • Page 53: Installation Environment

    4.1. Space requirement No access is required from the rear or either side. The ACM 150 monitor may be against a wall or set back-to-back with another monitor.

  • Page 56: Electrical Power

    The user must install an external circuit breaker for the power supply line to the ACM 150. It should be dedicated and rated for 20 A at 115 Vac with a minimum of 10,000 AIC (amperes interrupting capacity). Honeywell does not provide an external circuit breaker.

  • Page 57: Emergency Power-Off (Epo) Option

    Lockout/Tagout procedures. 5.2.2. Emergency Power-Off (EPO) option Some facilities require equipment like the ACM 150 monitor to have an EPO (or panic) switch. The user can add an EPO switch between the external breaker/switch and the Main Power Switch.

    This sequence can cycle repeatedly and may result in exposure to toxic gas while ERT personnel are repairing the leak. If the ACM 150 monitor output relays are used to shut down the gas source and interrupt the gas flow, a latching relay must be used in the control loop. If not, the ACM 150 monitor relay will shut down the gas source and stop the leak detected by the ACM 150 monitor.

  • Page 73: Computer Information

    Typically, the ACM 150 monitor operates in normal scanning mode. The display updates each time the ACM 150 monitor completes a scan of a sample area. A scan samples the air from that area, analyzes the sample, and displays the results. The cycle time for each update depends upon the setup and configuration of the ACM 150 monitor.

  • Page 79: Relay Activation

    Figure 40. Export Events 6.5.2. Relay activation When an Alarm 1/Alarm 2 Incident occurs, the ACM 150 monitor software activates the corresponding relays. All ACM 150 monitors have at least 80 output relays, and each relay's action is programmable. The default setup for the ACM 150 monitor assigns these relays to areas 1-40.

  • Page 80: Action Plan

    Typically, alarm incidents are brief and quickly clear if the alarm event activates automatic gas shutdown. With the gas supply cut off, the leak should dissipate. However, if the leak is not shut off, the ACM 150 monitor will likely sense the alarm event each time it scans the leaking area(s).

    ACM 150 7.6.3. Reviewing and changing the order of scan You must wait to log in with an access code to review the scan order, but you may not change it. After you log in, you may edit the sequence and enable or disable points. When editing the Order of the Scan, follow the steps in.

  • Page 102: Figure 59. Editing The Order Of Scan

    Decide on the scan sequence you want to use before you make any changes. Note that points may be scanned in any sequence. If you want the ACM 150 monitor to spend more time scanning one or more critical points, you can repeat the point(s) in the sequence.

  • Page 103: Composite Points

    Composite Point groups have only one advantage. They shorten the scan cycle. Since the ACM 150 monitor typically monitors air with no target gases, the readings are usually zero. Composite sampling enables the ACM 150 monitor to increase its scan rate until a gas leak occurs.

  • Page 104: Settings - Method Manager

    ACM 150 CAUTION Composite point sampling may expose employees to hazardous conditions by lowering the gas detection capability. Use Composite Points only if the rate of scan must be increased. The following rules apply and must be followed: Group only the sample areas to avoid combining long and short tube runs, which may cause an imbalance in the composite mixture.
