Install all protective equipment coversand safety ground leads after setup. Failure to replace covers and groundleads could result in serious injury or death. Models 218, 225, and 132 (Analog) Electronics refer to paragraph 3-2. Model 218A Electronics refer to paragraph 3-3. MODEL TC200 Electronics refer to paragraph 3-4. Model 132 Digital Electronicsrefer to paragraph 3-5. 3-2 MODELS 218, 225, AND 132 (ANALOG) ELECTRONICS SETUP Before beginning operation, it is important that the probe heater set point of the existing electronics be changed to support the World Class 3000 probe. The set point adjustment procedure required for Models 218, 225, and 132 analog electronics is as follows: b. On temperature controller card, Figure 3-1, connect jumper wire from TP3 to either Pin 2 or Pin 7. (3) 3 c. Set voltmeter to read DC millivolts (MV). d. Attach voltmeter with positive (+) lead on TP1 and negative (-) on either Pin 2 or 7. e. Adjust potentiometer M110-1 to read -322.3 millivolts nominal. Figure 3-1. Temperature Controller Card Calibration Points Rosemount Analytical Inc. A Division of Emerson Process Management Setup 3-1 Instruction Bulletin 106-300NE Rev. 3.4 May 2000 World Class 3000 NOTE The voltage given above is for an ambient (machinery space) temperatureof 77°F (25°C). For each degree of ambient temperature above or below 77°F(25°C), add or subtract 0.242 mV fromthe nominal. Example; at 87°F (31°C), the nominal voltage of -322.3 shouldbe increased (made less negative) by10 x 0.242 or 2.42 mV, making the adjusted nominal -319.9. f. Remove voltmeter leads. g. Remove jumper wire. 3-3 MODEL 218A ELECTRONICS SETUP Before beginning operation, it is important that the probe heater set point of the existing electronics be changed to support the World Class 3000 probe. To convert the Model 218A Digital Electronics Package for use with the World Class 3000 Probe and Heater Power Supply, an EPROM change is necessary. Remove Main PCB and check back of board to identify unit as G02 or G04. The replacement EPROM needed is as identified below: G02 G04 United States 1M03192G01 1M02982G01 United Kingdom 1M03192G02 1M02982G02 Germany 1M03192G03 1M02982G03 France 1M03192G04 1M02982G04 Italy 1M03192G05 1M02982G05 NOTE The replacement EPROM when using amultiprobe averager unit is1M02982G10. To replace the EPROM, proceed as follows: a. Shut off and lock out power to the electronics package. b. Open electronics enclosure. c. On the Main PCB, Figure 3-2, locate and remove old EPROM. d. Replace with new EPROM. e. Close electronics enclosure and power up system. Figure 3-2. Main PCB (Model 218A) EPROM Replacement 3-2 Setup Rosemount Analytical Inc.
