Sievers 800 TOC Analyzer Flow Switch Upgrade

(Flow Switch Kit and Firmware 2.12 CBI)

1. Purpose: To describe the mechanical installation for the flow switch, firmware 2.12 CBI upgrade installation and operation of the flow switch.

2. Scope: This procedure describes the activities required to install the flow switch and firmware 2.12 CBI in all Model 800 series TOC analyzers. For TURBO analyzers, this procedure describes the installation and configuration of the flow switch. Turbo Analyzers will omit the firmware installation section.

3. Materials and Tools:

7/16" open end or adjustable wrench 1/2" open end wrench Flat head screwdriver Phillips head screwdriver Scriber

Teflon® tape

WARNINGS:

• A 60-micron filter must be used to ensure proper operation of the flow switch.

• Do not over tighten any fitting.

• Switch orientation should be no more than 15° from vertical alignment.

• Do not install units near ferrous metals, magnets or electromagnetic fields.

• Please review the enclosed Operation and Maintenance Manual. There have

been features added to the analyzers. These additions are dependent upon the firmware version and software version currently in use.

4. Mechanical installation

Refer to Figures One or Two for this procedure. Reference will depend on orientation of tubing from regulator.)

4.1. Remove the outlet PFA tube connector from the pressure regulator of the analyzer.

4.2. Detach the regulator from the analyzer by removing the two screws on the bottom of the mounting bracket making sure not to lose the fiber spacers.

4.3. Remove the elbow from the outlet side of the regulator and clean the port and connector threads of any Teflon® tape remains. Reapply 4 wraps of Teflon tape to the elbow and screw the fitting back into the regulator ending with the tube fitting pointing down as shown.

4.4. Reinstall the regulator to the analyzer with the two screws making sure to use the fiber spacers.

4.5. Remove the PFA tube from the inlet of the sampling block.

4.6. Position the flow switch and secure the end of the stainless steel U-tube to the regulator outlet. Wires must point up to have a calibrated normally open switch.

4.7. Secure the PFA tube from the outlet of the switch to the inlet of the sampling block.

4.8. Connect the wires from the flow switch to the Binary Input Module, polarity not important to the binary module.

4.9. Route the electrical cable as desired and plug the end into the AUX PORT on the opposite side of the instrument.

4.10. If installing the switch on a TURBO analyzer, proceed to 6, if not proceed to 5.

5. Firmware installation

5.1. Print the current constants.

Any IBM compatible dot matrix printer with a parallel printer cable equipped with a 25pin connection may be used. It is very advantageous to have a printout of the constant values.

If a printer is not available, go to Step 5.2.

5.1.1. From the RUN-TIME Menu, press STOP TOC.

5.1.2. The MAIN Menu will be displayed select SETUP, press Enter.

5.1.3. Select PRINTER, press Enter.

5.1.4. Select PRINT CONSTANTS, press Enter.

5.2. If a printer is not available, access the FACTORY ACCESS Menu to scroll through and record constant values on the Constants Record Form within this procedure.

Constant values for C1THERM A, C2THERM A, C1THERM B, AND C2THERM B will be rounded values. The displayed constant value will differ from the printed constant value. This should not impact the analyzer’s performance. Contact GE Analytical Instruments for the last printed Constant Value list, if desired.

5.2.1. From the MAIN menu select CALIBRATE, press Enter.

5.2.2. Select TC ZERO OFFSET, press Enter.

5.2.5. Constants will be displayed in the sequence listed on the Constants Record

Form. Record each constant value on the form contained within this document.

IMPORTANT:

It is critical that this Printout or Constants Record Form is retained for

comparison to the Constant Printout or Record Form at end of upgrade

procedure. These Constants will have to be checked and any variations

must be corrected after the upgrade is completed.

5.2.7. Record Dates and Percents for consumables on the Constants Record

Form. These will need to be reentered after upgrade.

5.2.8. From the MAIN MENU select CONSUMABLES, press Enter.

5.2.10. REAGENT FLUSH is not a consumable to record.

5.2.11. Print or record Errors and Warnings if desired.

5.2.12. Data on the Ram Card will not be erased or affected in any way upon performing this procedure.

5.3. Replace the EPROM chip (IC chip).

CAUTION:

Prior to performing the following instructions it is essential, to be grounded

according to established procedures. Failure to be properly grounded will

result in damage to the EPROM Chip and void the warranty.

5.3.1. Turn off the analyzer power and disconnect the power cord.

5.3.2. Lift the analyzer cover and locate the PC electronics board, refer to Figure Six.

5.3.3. Depending on the type of chip holder in the analyzer, different techniques are required to replace the existing EPROM with the EPROM labeled 2.12CBI. Facing the analyzer’s front panel, locate the EPROM socket on the left side of the PC electronics board near the rear of the analyzer. If the chip socket has a metal lever at the top, it is a Zero Insertion Force Socket (Step 5.3.4). If the chip socket does not have a lever, it is a Low Profile Socket (step 5.3.5). Figure Six illustrates the low profile socket. Use the appropriate instruction to replace the chip.
