Page 13: Chapter 2 Installation
UNPACKING The Model 200L Single Dilution Probe Controller is shipped complete in one container. If, upon receipt of the controller, there is obvious damage to the shipping container, notify the carrier immediately and hold for inspection. -
Page 14: Installation Procedure
SYSTEM PLUMBING CONNECTIONS Connecting the various lines to the rear panel of the Model 200L Single Dilution Probe Controller is illustrated in Figure 2-3. If the unit was purchased with a system, please refer to those appropriate documentation for proper connections. All tubing connected to the controller is ¼"... -
Page 15: Startup Procedure
LEDs turn ON in turn. The Model 200L Single Dilution Probe Controller is now ready to be installed either in a rack assembly or for test bench purposes. With the unit placed in a secured location, the lines to the unit can be connected. - Page 16 Chapter 2 Installation The connection lines from the dilution controller to the dilution sample probe should be properly labeled and connected to the correct port fitting. A pressure of 60 to 80 psig of clean zero air is supplied to the high pressure air inlet port. The air inlet is then reduced to approximately 40 psig by a dilution air regulator.

- Page 18 Chapter 2 Installation The sonic orifice uses a quartz wool to prevent sample particulates to enter the critical flow passage. The quartz wool acts as a particulate filter (Figure 2-5). The quartz wool is periodically changed every three months for continuous monitoring. The quartz wool is placed into the end of the orifice against a glass frit.

Page 19: Chapter 3 Operation
CHAPTER OPERATION In order to fully understand the operation of the Model 200L Single Dilution Probe Controller, a general knowledge of the electronics, flow, and subassemblies is recommended. A better understanding of the components themselves will allow the user to correctly change parts or subassemblies more efficiently. - Page 20 Chapter 3 Operation 62P715 Figure 3-1. Relay Board Assembly...

Page 21: Switch Board
Chapter 3 Operation SWITCH BOARD A rotary switch allows the path for the +24 Volts DC to the solid state relays from the relay board Assembly. The rotary switch, behind the switch board assembly shown in Figure 3-2, uses two adjustable locking washers to select from zero, sample, and 5 span valves. -
Page 22: Rear Terminal Board
Chapter 3 Operation REAR TERMINAL BOARD The rear terminal board provides the necessary means to deliver status contact for zero, sample, and 5 span valves (Figure 3-3). A constant +24 Volts DC is present from the Rear Terminal Board for remote activation from a data acquisition system or relay contact configurations. - Page 23 Chapter 3 Operation Two ribbon cables are connected from the rear terminal board to the relay board assembly. J9 from the relay board provides the status contacts for zero air and one to five span gas valves. The connections for the status and remote activation are illustrated in Figure 3-4 * NU = Not Used.

Page 24: Gauges
Chapter 3 Operation GAUGES Three gauges are affixed to the front panel of the Model 200L Single Dilution Probe Controller. These are vacuum, dilution air, and zero air (Figure 3-5). The dilution air gauge should read from 30 to 45 psig with a dilution orifice setting of 100:1. A leak check should be performed if this pressure is below 30 psig,. -
Page 25: Flow Description
Chapter 3 Operation FLOW DESCRIPTION Flow path of the air and gas streams are the primary function of the Model 200L Single Dilution Probe Controller. The controller is utilized in conjunction with one dilution probe. The configuration will be determined by site application and the customer’s request or requirements. -
Page 26: Subassemblies
Chapter 3 Operation SUBASSEMBLIES The subassemblies shown in Figure 3-7 are available from Thermo Environmental Spare Parts Department. The subassemblies allow the customer to replace inoperable parts and troubleshoot efficiently. -
Page 27: Chapter 4 Calibration
This chapter describes the procedure for performing the multipoint calibration with the Model 200L Single Dilution Probe Controller using the Model 42C and NO as an example. Although the Model 42C is used in this example, a variety of instruments can be used to check the performance of the Model 200L Single Dilution Probe Controller. -
Page 28: Dilution Calculations
150 mil/min 20:1 6947 After the appropriate critical orifice is determined, the adjustment for the Model 200L Single Dilution Probe Controller can be made. Connect the analyzer unit to the diluted sample from the probe. Be sure that the gas is vented to the atmosphere. - Page 29 Chapter 4 Calibration Performance The dilution air is adjusted to mix the right amount of air with the gas in order to achieve the correct dilution ratio. Adjusting the dilution air regulator clockwise will introduce more air to the probe, thus increasing the dilution ratio. Adjusting the dilution air regulator counter- clockwise will reduce the amount of air introduced to the probe, thus decreasing the dilution ratio.

Model 200L Single Dilution Probe Controller to ensure proper, uninterrupted operation. For example, the precision orifices and gauges should be checked. This chapter also explains how to replace the Model 200L Single Dilution Probe Controller subassemblies. It is recommended that the individual be familiar with the subassemblies before attempting to disassemble or repair the controller unit. -

Chapter 5 Preventative Maintenance RELAY BOARD REPLACEMENT (Figure 3-1) Equipment required: New Relay Board Assy. (Part No. 14672) Nut Driver or Adjustable Wrench Flat Tip Screwdriver Slide the unit from the rack cabinet, so the cover can be taken off. Remove the four screws that hold the cover above the unit. -
Page 33: Precision Orifice Check
Chapter 5 Preventative Maintenance PRECISION ORIFICE CHECK The precision orifice allows a certain amount of flow for the zero and span gas to the dilution probe. The flow must be enough for the critical orifice to draw from while providing a reasonable lag time through the sample line. SPAN SOLENOID VALVE CHECK The valves can be checked by using air flow applied to the common port of the valve. -
Page 34: Flow Leak Check
FLOW LEAK CHECKING This procedure enables the user to thoroughly check the controller for leaks. Leak checking should only be conducted if the Model 200L Single Dilution Probe Controller is suspected of performance calibration errors. Leak checking the controller ensures that the unit does not produce erroneous readings on the gas analyzer. -
