Page 32: Space Requirements
Space Requirements Refer to Dimensions drawings shipped with the analyzer for mounting hole and minimum door swing dimensions. Tools, Equipment, and Supplies Required for Installation To install the analyzer, you need the following: • M4 hex driver required to turn the Upper/Lower Cam Pins used to secure the Optical Bench on the Optical Bench Mount inside the Electronics En- closure.
Page 33 • Supply of adequately-sized electrical supply cable, which must be approved for the local wiring regulations and by electrical codes for the hazardous location, and which must be rated at 600 Volts and 105 °C (221 °F). • A supply of 1/4-inch non-rigid tubing, such as Teflon, for the Sample and Vent gas lines, and for the Calibration and Zero gas lines.

If there is a discrepancy, contact the local distributor or the factory. The 9933 Analyzer is available in two operating voltage configura- tions (120 VAC or 240 VAC), configured by AMETEK at the factory per customer/end user requirements. See the Product Label on the Electronics Enclosure door for the operat- ing voltage for your analyzer before working on the analyzer.
Page 58 4. Feed the AC power cable through the appropriate cable gland and secure the cable gland to the Power Entry Port on the bottom of the Electronics Enclosure (see Figure 2-9). Connect the GND wire to the Ground Stud (see Figure 2-12.2). Connect the L1 and L2(N) wires to the terminals on the AC Distribution Board (see Figure 2-12.2).
Page 59: Pressure Leak Check
Pressure Leak Check The analyzer has been checked at the factory for pressure leaks. However, fittings can loosen during transport. Also, fittings are tightened when the Sample, Vent, and other lines are connected during initial installation, and fit- tings are loosened/retightened whenever the Measuring Cell or other sample system parts are removed and reinstalled (i.e., for service).

To avoid tearing the Membrane Filters in the Filterblock, always bleed down the sample system pressure on the downstream (outlet) side of the Filterblock. Pressure differentials of more than 210 kPa (30 PSI) from the inlet side to the outlet side can tear the Filters and they will have to be replaced .

Page 65: Start-Up And Verification
Start-Up and Verification When powering up the analyzer, certain checks should be performed to en- sure the analyzer is operating properly and is ready to be commissioned into operation. These checks are discussed in the following procedure. If there are problems encountered during power-up, see “Performing Start-Up Diagnostic Checks”...
Page 66: Powering Up The Analyzer
Powering Up the Analyzer IMPORTANT Performing analyzer start-up and verification procedures requires you to work with analyzer’s HMI. Familiarize yourself with the software before working on the analyzer. See Chapter 3 for details on how to navigate through the software. Certain checks should be performed to ensure the analyzer is operating properly.
Page 67 Figure 2-14-2. HMI-Display, establishing communications with the analyzer’s UV Bench Controller board (and Process Sensor Controller board, if sensors are installed) is in progress. If the splash screen or Connecting to controllers... screens do not appear within approximately 30 seconds, cycle the analyzer power Off then On again.
Page 68 If the HMI displays the message “SEN99xx Controller not connected to “993X Gas Sensors” Manual HMI unit” (Figure 2-14.4) check the Communications Cables between the Supplement (AMETEK Part No. UV Bench Controller board and the Process Sensor Controller board or 10939-15-5) for sensor details.

If necessary, replace the RTD with an AMETEK-approved replacement part. Contact AMETEK Service for assistance. Problem Encountered Temperature Low status remains active after the analyzer has been allowed to warm up for at least 30 minutes and the heater duty cycle remains high (e.g., 100 %).
Page 71: Zero-Calibrating The Analyzer Upon Initial Start-Up
Zero-Calibrating the Analyzer Upon Initial Start-Up The 9933 Gas Analyzer has been Zero-calibrated at the factory before shipping. However, AMETEK recommends that you recalibrate the analyzer after initial start-up and before commissioning it into operation for the first time.
Page 72: Normal Operation
The data – which the HMI stores for the last 2 hours of operation, at 30-second intervals – can also be saved to a USB Flash Drive, when inserted in the 9933 Gas Analyzer’s USB port (mounted inside the analyzer, below the HMI). To ac- cess the USB port, open the analyzer’s Electronics Enclosure door.

Page 82: Entering Passwords To Change Analyzer Parameter Settings
Entering Passwords to Change Analyzer Parameter Settings A password is required to make changes to analyzer settings or parameters. There are two different levels of passwords: Screens that have a WHITE title require a Level1 password (1 3 5 7). Screens that have BLUE title require a Level2 password (2 4 6 8).
Page 83: Changing The Modbus® Node Address
Unit ID is the Modbus node/slave ID of the Controller board. For • 993X analyzers, the AMETEK factory default is ‘101’ for the UV99XX UV Bench Controller board and, if installed, ‘102’ for the SEN99XX Pro- cess Sensor Controller board.
Page 84: Upgrading Hmi-Display Unit Software
Upgrading HMI-Display Unit Software The HMI-Display Software can be upgraded by manually copying it to a USB Flash Drive (Standard method) and then installing it, or remotely using the Al- ternate FTP method.

Page 96: Viewing Uv Bench Setup Parameters
Target PMT Signal (V) This is the maximum PMT (photomultiplier tube) signal level (volts) that will be used during the Auto Setup (range is 0–10 V). AMETEK does not recommend adjusting this value from the factory default setting un- less advised to do so by AMETEK Service.
Page 97 Lamp2 Base This is the lamp base current (mA) for Lamps 1 and 2. This is the “simmer” current when the lamp is not being pulsed. AMETEK does not recom- mend adjusting this value from the factory default setting unless advised to do so by AMETEK Service.

Page 160: Monitoring Lamp Readings To "Predict" Lamp End-Of-Life
Monitoring Lamp Readings to “Predict” Lamp End-of-Life Recording lamp readings – whether on a new analyzer, or following lamp replacement – will help you to “predict” lamp end-of-life. This can help you determine when to order and replace the lamps, without unnecessary analyzer downtime.
Page 161 During normal analyzer operation, the lamp pulse mA levels are continuously adjusted in the software by the ALC (automatic lamp control), to keep the PMT (photomultiplier tube) signals from the Ref- erence path at the levels that resulted from the previous Auto Setup. As a lamp ages, most pulse mA levels associated to that lamp will be adjusted higher, signifying diminishing lamp life.
