CHAPTER 1: INTRODUCTION
See Instruction Manual 84372 supplied with the instrument for standard operating information for the 770MAX. This service manual covers instrument calibration, upgrades, RS232 communications and other information for troubleshooting and training.
The 770MAX is provided with a Help key which provides supplementary information about the area of the menus being displayed. It can be especially helpful in initial configuration.
INSTRUMENT OVERVIEW
The 770MAX series utilizes 3 or 4 surface-mount printed circuit boards plus a display module which slide into the molded case and are held in place by the front cover secured by two screws.
The main circuit board is located in the front of the instrument. It contains the display module, main processor, operating firmware and flash memory which retains all setup configuration data plus calibration data for (standard) analog outputs 1-4.
The power supply circuit board is located on the left side of the instrument. It contains the universal 100-240 VAC or 24 VDC power supply plus terminal connections for the 4 standard analog outputs, RS232 communications, discrete inputs and outputs and pulse flow input circuits.
The measurement circuit board is on the right side of the instrument and contains the measuring and communication interface circuits for smart sensors plus the NVRAM with measuring circuit calibration data.
The options circuit board, if used, is in the center and contains 4 relays, and may contain 4 additional analog output circuits and their calibration data, depending on the option specified. The label on the rear of the case depends on which, if any, options board is installed. An options board may be installed in the field using the appropriate kit of parts.

CHAPTER 2: METER CALIBRATION
The 770MAX has been factory calibrated to meet its specifications. It is not normally necessary to re­calibrate unless extreme conditions cause out-of­spec operation shown by verification. Periodic verification or calibration may also be necessary to conform with QC requirements.
The 770MAX may be calibrated using high precision resistance decade boxes, voltage source and frequency generator with the following procedures. This is intended only for installations that have a policy of traceability to their own internal standards. Standards equipment accuracies must exceed the 770MAX specifications as required by the applicable QC policy.
NOTE: This is an extensive process requiring 72 calibration points to fully cover all measurement ranges of all parameters on all channels. It is strongly recommended, where possible, to use the Thornton 1875 Automatic Smart Calibrator Kit which is supplied with a traceable certificate of accuracy. It also enables printing out calibration certificates for instruments it has calibrated. It is supplied with its own instruction manual.
It is necessary to verify and/or calibrate only those measuring circuits actually being used in the installation. The following Adapters are needed to interface with standards equipment:
leads—two for resistance and two for temperature.)

10. Set the test equipment for exactly the same verification value from Table A.
11. Allow the error value to fully stabilize and then confirm that the resulting Error (in percent of reading, except for voltage) is acceptable.
12. NOTE: Calibration is unnecessary if the error is smaller than the limit of error of the standard or of the 770MAX specification.
1000-82 resistance adapter for conductivity, resistivity, temperature.
1000-79 voltage adapter for pH, ORP, pressure, level.
1000-83 frequency adapter for flow. Before attempting calibration, perform a verification
to determine if calibration is, in fact, necessary. Verify at least one value for each internal range. Recommended values are given in the table at the end of the verification procedure.

CHAPTER 3: ANALOG OUTPUT CALIBRATION
ANALOG OUTPUT CALIBRATION
This section describes calibration of the 0/4-20 mA output signals. For startup information to scale the range that the signal represents in engineering units, see main Instruction Manual 84372, Chapter
4. Analog output signals are factory calibrated
within specifications but may be re-calibrated if necessary.
The 770MAX analog output calibration is performed by measuring the output signal when it is set to its minimum (4 mA) and maximum (20 mA) limits and entering the exact mA value into the instrument’s display. The 770MAX automatically computes any deviation from 4 and 20 mA and adjusts itself accordingly. Verification of outputs is accomplished through a diagnostic menu.
It is desirable to calibrate and verify when the system receiving instrumentation is connected in the circuit to present the approximate operating load to the circuit. Maximum load is 500 ohms.
Calibration Procedure
7. Read the exact output current on the milli­ammeter and enter that precise value into the “20 mA reads= 20.000” screen of the 770MAX and press Page Down. (NOTE: For meters with
software version 2.5 or greater, at the “20mA adjust=” screen, use arrow keys and re-adjust % value displayed until milli-ammeter reads
20.000mA and press Page Down.)
8. Enter the date and press Page Down to save it.
9. Press page up twice and repeat steps 2 and 5-8 for the additional outputs.
10. Press Menus twice to exit and resume normal measurement. The 770MAX automatically computes any deviation from 4 and 20 mA and adjusts itself accordingly.
11. Reactivate any system suspended in step 1.
ANALOG OUTPUT VERIFICATION
Analog outputs may be verified using the 770MAX diagnostic menu and a milli-ammeter. The menu allows setting the analog outputs to specific mA values.
1. Disable or place in manual any control system using the analog output signals since they will be interrupted during calibration.
2. Connect a high precision milli-ammeter in series with the analog output signal to be calibrated. (See Chapter 1 for terminal connections.)
3. Press Menus and Up arrow to display “Goto: Calibrate”, and press Enter.
4. Press Up arrow to display, “Goto: Analog”, and press Enter twice, (press Enter once for meters with software version 2.5 or greater), passing through the Hold Time screen.
5. Select the output signal # to be calibrated and press Enter.
6. Read the exact output current on the milli­ammeter and enter that precise value into the “4 mA reads= 4.0000” screen and press Page Down. (NOTE: For meters with software version
2.5 or greater, at the “4mA adjust=” screen, use arrow keys and re-adjust % value displayed until milli-ammeter reads 4.000mA and press Page Down.)
Verification Procedure
1. Disable or place in manual any control system using the analog output signals since they will be interrupted during verification.
2. Connect a high precision milli-ammeter in series with the analog output signal to be verified. (See Chapter 1 or terminal connections.)
3. Press Menus and Down arrow to display, “Goto: Diagnostic” and press Enter.
4. Use Up/down arrows if needed to display, “Goto: Analog Output” and press Enter.
5. Using up/down arrows select the Analog Output # to be verified and press Enter.
6. Using Up/down arrows set Output @ 4.00mA or another level to be verified.
7. Press Page Down.
8. Measure the actual output on the milli-ammeter, record the value and compare it with 770MAX output specifications.

OUTPUT UPGRADES
Relays and additional analog outputs may be added with circuit boards to an existing 775-_A0 Instrument (which has no option board already installed). Kit 1000-91 adds 4 SPDT relays to convert an instrument to model 775-_A1. Kit 1000­92 adds 4 SPDT relays and 4 additional analog outputs, to convert an instrument to model 775-_A2.
CAUTION: Adding these outputs restricts operating conditions:
Kit 1000-91 lowers the maximum ambient temperature rating to 104°F (40°C) when operating on 230 VAC power.
Kit 1000-92 lowers the maximum ambient temperature rating to 104°F (40°C) on 115 VAC power and cannot be used above 130 VAC. This kit may only be installed in an instrument with main software revision 1.5 or higher.

CHAPTER 5: TROUBLESHOOTING
ON-LINE ERROR MESSAGES
The following messages can appear in the “Go to: Messages” menu to indicate error conditions or problems with reading sensors. This menu area should always be checked first when an operating problem is encountered.
1. "Measure PCB failed" – hardware failure.
2. "No sensor on chan"
3. "Invalid sensor type"
4. "Sensor checksum err"
5. "Sensor const bad" – the sensor multiplier or adder factor may be wrong.
6. "Invalid pipe ID"
7. "Invalid tank height"
8. "Invalid channel" – the selected channel is wrong for the desired measurement (i.e. %Rejection, ratio, etc.).
9. "Res sensor open" – patch cord or sensor cable may be bad.
10. "Res sensor shorted" – patch cord or sensor cable may be bad.
11. "Compensate error" – wrong compensation method selected or conductivity may be too high for this compensation method.
12. "Temp out of range"
13. "Unable to measure R" – unable to measure resistance of sensor (air bubble, dry cell, etc.).
14. "Invalid max PSI"
23. "Range may be wrong" – measurement may have a wrong range (i.e. set for S/cm instead of uS/cm).
24. "Invalid setpoint #"
25. "Reference volts bad" – for pressure sensors this is a bad sensor.
26. "Flow rate is 0" – the flow rate is zero gpm so the calculated measurement is zero or over range.
27. "Bad meter calibrate" – a meter calibration factor is bad, should recalibrate.
28. "A/D over range" – the A/D convert reported an error, may be a defective measurement board.
29. "Unknown error #xxxx"
“LSC is Locked” could appear in the startup screen and indicates that internal local serial channel communication has halted. This could be caused by loose internal connections. Re-seat all circuit board and ribbon cable connectors and re-power the instrument. If the message persists, factory service will be required.
NOTE: When a 500TOC Sensor is connected to a 770MAX instrument, the ‘Messages’ menu area will appear different. There will be three options shown on the message display; 1-Current Messages, 2­Messages History, and 3-Clear History. There may be Error and Fault messages specific to the 5000TOC Sensor within these menu options. Refer to the 5000TOC operations manual, 84445 for detailed information regarding Error and Fault messages specific to the 5000TOC Sensor and the use of these menus.
15. "Invalid tank area"
16. "Unknown measurement"
17. "Too big to display" – the measurement is too large to be displayed.
18. "Total flow over" – total flow has reached the upper limit.
19. "Temperature high"
20. "Voltage over range" – the voltage from the sensor (pH, pressure) is too high (bad sensor).
21. "Invalid max GPM"
22. "Check TDS factor"
Chapter 5 Troubleshooting 11
SENSOR TROUBLESHOOTING
Temp. Compensated Measurements
Temperature compensated measurements such as conductivity/resistivity and pH require the temperature signal from the sensor to be within range or the compensated measurement will display asterisks. If the temperature signal has failed or is not available, operation can be continued by changing the temperature source (under the Measurements menu) to a fixed value or to use the temperature signal from another channel that is also correct for this measurement. In some cases, using temperature from another channel
Page 18
may be desirable anyway, to obtain a faster responding or more accurate temperature signal.
“Raw” Sensor Signals
Direct reading of the sensor output is available from the “Measurements” menu. It gives “raw” readings in base units, e.g. Hz for flowrate. It is not adjusted with calibration factors, temperature compensation, etc. and is helpful in finding the cause of erroneous readings.
To view the “raw” reading, press Menus and select the desired measurement. Page down to the last normal screen (indicated by disappearance of the down arrow in the lower right corner), then page down one more to see “Raw reading from the sensor= XXXXX XX” plus identification of channel (and internal range for resistivity).

CHAPTER 6: RS232 COMMUNICATIONS
Connections for the RS232 serial port are shown in Chapter 4.
GENERAL
The Serial Port Communications command set provides the user with complete control and configuration of a meter.
1. All messages sent to and from the meter will consist of the printable set of ASCII characters. Each message will be terminated with a carriage-return (<CR>) character.
2. All messages sent to the 770MAX will receive a response. The response will consist of the requested data, an "OK" message, or an error message.
3. All commands must specify an identifier address (same as the network address). The identifier address “00” will be read by any meter as its address. Therefore there are two addresses that the meter will respond to: address “00” and the address set as the Network Address.
COMMAND FORMAT
The format of all commands is: "axxc…c<CR>". Where:
"a" is the opcode (upper case letter from A to Z). "xx" This address is "00" for the serial port interface.
"c…c" is the command data. Format may include “=” for setting parameters or special function characters <CR> is the ASCII carriage-return character.
RESPONSE FORMAT
The format of all responses is: "axx=c…c<CR>". Where:
"a" is the opcode (upper case letter from A to Z). "xx" is the network address of the unit (from 01 to FF hexadecimal).
"c…c" is the response data. <CR> is the ASCII carriage-return character.
The response data will be one of the following types:
1. Command Accepted message "OK".
2. Command Data data depends upon the command type.
3. Command Rejected "ERROR #yy" where "yy" is an error code.
: if the command is accepted then the response data section will consist of the
: if the command requests data then that information will be returned. The format of the
: if the command is rejected then an error message will be returned with the format:
ERROR CODES
The following error codes will be used when a command is rejected (the form at is "ERRO R #xx"):
01: invalid opcode. 02: parameter error. 03: checksum error. 04: parity error. 05: unit is not available. 06: command failed. 07: timeout error. 0C: overflow error 0D: invalid board type 0E: data not available

“mmnnoopp” = IEEE floating point data (4 bytes, * ASCII characters). NOTE – the floating point number is sent in reverse byte order, i.e. the floating point number is ppoonnmm in IEEE format. Bit seven of the first byte (pp) is the sign bit for the number (=1 for a negative number). The next 8 bits are the exponent (power of 2). The exponent is offset by 127 (i.e. if the exponent is 126 then the exponent is –1, if the exponent is 127 then the exponent is 0, etc.). If the exponent is 00 and the mantissa is 0 then the number is 0. If the exponent is FF then the whole floating point value is not a number (this typically occurs from an overflow such as a divide by 0).

CHAPTER 7: MENU TREES
The following menu trees illustrate the general sequence of settings available in the 770MAX. However, some low level menu items are dependent on the type of sensor connected and on previous menu selections. For example, only a flow measurement with totalized flow units selected will show the menu field for setting External Reset. Also, the model of 770MAX will determine how many analog outputs and relays are present for configuration.
The screens below will appear after pressing Menu only if security has been enabled. Otherwise pressing Menu accesses the Main Menu directly, as shown on the following pages.

CHAPTER 8: PRINTER INSTALLATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS FOR USE WITH THE THORNTON 770MAX SERIES INSTRUMENTS
1. Connect the AC adapter to the printer and load paper.
2. Connect the communications cable from the printer to the 770MAX series meter. The cable has a 9-pin (DB-9) male connector on one end and three tinned leads at the other end. The male 9-pin connector is attached to the connector located at the rear of the printer. Use Table 1 and the operating manual for the meter to determine how to wire the leads to the meter. Connect the leads to the pluggable connector that comes with each meter.
3. If the printer power is turned ON, turn the power switch OFF.
4. While pressing the ONLINE button, turn the power switch ON. Release the ONLINE button after the list of the current settings starts printing.
5. The printer will print the following prompt:
Continue? :Push ‘ONLINE SW’ Write? :Push ‘Paper feed SW’
6. Compare the DIP SW settings to the values in Tables 2-4 in this Installation manual.
7. If any of the DIP SW settings need to be changed, push the ON LINE button. Do not change any of the critical settings noted as ** in Tables 2-4. Go to Step 9.
8. If none of the DIP settings in Tables 2-4 need to be changed, push the FEED button. Go to Step 16.
9. The printer will print Dip SW-1, then prompt for the input of new settings starting with 1 and continuing through 8 of software Dip SW-1. To select OFF, press the FEED button. To select ON, press the ONLINE button. The resulting setting is then printed out to signify confirmation of the new setting. The ONLINE or FEED lamp lights also light when pressed to confirm button operation.
The Dip SW Set mode can not be canceled once it is initiated. Input either “ON” or ”OFF” for every setting in order from switch number 1 through 8.
10. After switch number 8 on DIP SW-1 is set, the printer once again prompts with
Continue? :Push ‘ONLINE SW’ Write? :Push ‘Paper feed SW’
11. If any of the DIP SW settings on SW-2 or SW-3 need to be changed, push the ON LINE button. Do not change any of the critical settings noted as * in Tables 2-4. Go to Step 13.
12. If the DIP SW-2 and SW-3 settings do not need to be changed, push the FEED button. Go to Step 16.
13. Repeat according to Step 9. As the settings are printed, press FEED to select OFF and press ONLINE to select ON.
14. After switch number 8 on DIP SW-2 is set, the printer once again prompts with
Continue? :Push ‘ONLINE SW’ Write? :Push ‘Paper feed SW’
15. Repeat this process for SW-3.
16. After all settings are selected, the ONLINE and FEED lamps blink alternately and the new settings are written to the memory. When the printer finishes writing everything to memory, “Dip SW setting
complete!” is printed and the printer returns to ONLINE mode.
Never turn the printer off while the new settings are being written to the memory. Always wait until “Dip SW setting complete!!” is printed. Then turn the power off.
