OVERVIEW

The MICRO-800 Datalogger is designed to support the reading of a large number of Geokon

Vibrating Wire Instruments for various unattended data collection applications through the use of an internal Geokon Model 8032 Multiplexer. Weatherproof packaging allows the unit to be installed in field environments where inhospitable conditions prevail. The Nema 4X enclosure also has a provision for locking to limit access to responsible field personnel.

A basic datalogging system consists of the Campbell Scientific CR800 datalogger, an internal multiplexer and an External Multiplexer port. Multiplexers expand the system by increments of

16 or 32 channels depending on the instrument type and configuration. The standard model

8025-2 Micro-800 datalogger can support one (1) internal Multiplexer and (1) external

Multiplexer. The External Multiplexer port can also be used to Daisychain up to eight (8)

Multiplexers (please see 8032 Manual for more information). The standard model 8025-4 and

8025-5 dataloggers are identical to the model 8025-2, but are configured for 32 VW gages only

(8025-4) or 32 Thermistors only (8025-5). The standard model 8025-3 Micro-800 datalogger can support two (2) internal 16 channel Muliplexers and has 32 cable enties.

1.0 HARDWARE

The controller portion of the MICRO-800 datalogger consists of a Campbell Scientific CR800

Measurement and Control Datalogger. To gain an understanding on the workings and capabilities of the CR800 it is necessary to read the Overview section of the CR800 Operator’s Manual. The

CR800 Operator’s Manual is available as a pdf file on the Campbell Scientific Resource CD supplied with the datalogger.

A Campbell Scientific AVW200 Vibrating Wire Interface provides the required excitation and signal processing for the vibrating wire sensors connected to the Datalogger. The AVW200 uses spectral analysis to find the resonant frequency of the Vibrating Wire Gage. The AVW200 is also used to measure the thermistor used in Geokon’s vibrating wire instruments. For complete specifications of the AVW200 see the AVW200 Instruction Manual on the Campbell Scientific

Resource CD.

A dual-mode battery charging circuit board is used to provide the charging voltage for proper maintenance of the installed lead acid battery. The circuit board contains fused protected terminal blocks used to provide a nominal 12VDC supply for devices such as the CR800 and

Model 8032 Multiplexer board. In some cases a Solar Charge Regulator may be used in place of the dual-mode charger.

The Model 8032 Multiplexer board expands the number of channels that can be read by the

MICRO-800 Datalogger. The channel switching is accomplished by mechanical relays mounted on the underside of the circuit board and the transducer connections are accomplished by friction locking terminals. Power, reset and clocking for the multiplexer are supplied by the MICRO-800.

The Model 8032 multiplexer can be configured for 16x4 or 32x2 channels depending on application. Please see Appendix F for more information on the Geokon Model 8032 multiplexer.

A 12V – 7Ah lead acid battery is used to provide power for the datalogger. The battery is provided to supply operating power for a limited period of time should the AC or solar power, used to maintain the battery, be interrupted. Under normal operating conditions and proper maintenance, the life expectancy of the battery is approximately five (5) years.

1.1 INSTALLATION

The recommended method of installation involves attaching the enclosure (MICRO-800) to a fixed structure, such as a wall, in an upright position (Figure 1). Mounting dimensions shown in inches.

Figure 1

1.2 Power

After the Datalogger is installed the charger can be plugged into the AC mains and the On/Off switch S1 on the Charge Regulation circuit board switched to the “On” position (Figure 2). It is recommended that the charger be left plugged in at all times (Section 3.1).

Figure 2

1.3 Earth Ground

An earth grounding lug is supplied on the exterior of the Micro-800 enclosure to connect the system to earth ground (Figure 3). A grounding rod can be driven (or other suitable attachment to earth utilized) to ground the system and provide a path to earth for protection against a lightning strike or other transient voltage. A 6’ to 8’ copper grounding rod connected to the

Dataloggers grounding lug with a large gauge wire (12 AWG or larger) is recommended. The earthing connection should be made as close to the Datalogger as possible.

3

1.4 Gages

At this time the vibrating wire sensors can be connected to the multiplexer. Please refer to

Appendix F for the appropriate connection description.

1.5 Communications

Standard communications with the Datalogger is established by connecting the supplied serial cable to the RS-232 port (Figure 3) and the COM port on a computer, or a USB port on the computer by using the provided USB to Serial converter cable.

Figure 3

2. SOFTWARE

The Micro-800 Datalogger is operated by a download file that is generated by a software program. The software package the MICRO-800 Datalogger may be supplied with is either

MultiLogger software (developed by Canary Systems, Inc, New London, NH) or LoggerNet software (developed by Campbell Scientific, Logan, Utah). Please refer to the manual supplied with the software for instructions on installing the software and creating the required download file for datalogger operation.

3. BATTERY MAINTENANCE

3.1 AC Power

The MICRO-800 is supplied with an external AC to DC power supply for maintaining the charge of the battery and providing power to the Datalogger and peripherals. It is imperative that the power supply remain connected to the Datalogger as the battery installed in the Datalogger is only provided as a temporary source of power should the power supply be disconnected or mains power interrupted. Actual run time solely on battery power will vary for each datalogging system, depending on the hardware configuration and sensor scan interval. If the battery voltage drops below 9.6 volts operation of the Datalogger will become erratic as evidenced by communication problems and possible improper measurements.

3.2 Solar Power

If AC mains power is not available, a properly sized solar panel can be used to provide power to maintain the charge state of the battery and provide power to the Datalogger and peripherals. The size of the solar panel is determined by geographic location of the Datalogger, hardware configuration, and the sensor scan interval.

3.3 External Battery

Additionally, a large external battery, such as a deep cycle marine battery, may be connected to the Datalogger via the supplied external power cable to provide power to the Datalogger and peripherals. When this type of battery is connected to the Datalogger the internal Datalogger battery is automatically disconnected from the system to prevent parasitic drain on the external battery.

3.4 Battery Replacement

If the internal Lead Acid Battery has failed it is recommend that the unit be returned to the factory for service by Geokon personnel. However, with skilled personnel and appropriate tools, it is possible for the user to replace the battery. Consult the factory for information.

3.5 Fuses

There are five fuses on the dual mode charger board of the MICRO-800 (Figure 2).

Once removed and with the power switch off, a fuse can be checked visually and with an ohmmeter. A gap may be evident (with some discoloration) if the fuse needs replacing. This can be verified by a high resistance measurement (mega-ohms) with an ohmmeter. If fuse needs replacing, insert one of the supplied replacement fuses. If there are no replacement fuses available, consult the factory or they can be purchased from an electrical supply house. All five fuses are 2 amp SLO-

BLO 5x20mm. Consult Appendix D.3. for fuse assignments.

4. TROUBLESHOOTING

This section will NOT attempt to cover all possible problems that could be encountered in the course of Datalogger operations. Consult the factory if other problems arise or remain unresolved.

• Cannot communicate with the Datalogger.

Suggestions:

1. The wrong communication cables are being used or the cables in use are defective.

Consult Appendix D.1.2 to verify cable pinout. Consult the factory for interfacing information.

2. The internal battery could be dead. Charge overnight and try again. If it still doesn’t work check the voltage across the terminals of the battery. If the voltage is still below 10 volts the battery may need to be replaced.

3. The wrong communication port is being used on the host computer (default is COM1).

Consult the appropriate software manual for instructions on changing the communication port.

4. The communication port on the host computer is defective. Verify the functioning and configuration of the COM port by using it with another RS-232 device, such as a modem or serial printer.

5. The Datalogger Auxiliary Fuse on the Dual-Mode Charger board is blown. Refer to

Appendix D.3 for proper fuse replacement.

• The system battery voltage and panel temperature read odd numbers.

Suggestions:

1. The system battery could be low. Charge and check again (see previous section).

2. A disruptive current loop may be operating as a result of improper grounding or excessive noise. Consult the factory for more information.

• The internal battery measurement does not increase and charging LED (Yellow =

Charging and Green = Charged) does not light when the AC adaptor is plugged in.

Suggestions:

The adaptor may be damaged. Check the output pins of the adaptor with a voltmeter.

The charger fuse is blown. Consult Section 3.5 for checking and/or replacement.

The internal battery is no good. Consult the factory.

• The Datalogger will not operate on external power.

Suggestions:

6

1. The external voltage supply is below operating limits. If the external source is a battery, charge it. If it’s a power supply, check the output with a voltmeter.

2.

•

The external power or battery fuse is blown (Section 3.5).

Loss of CR800 program and/or data.

Suggestions:

1. The system has experienced a voltage dropout or surge which disrupted operations.

2. The surge originated as a result of lightning. Install appropriate grounding. Install lightning protection devices on all incoming and outgoing lines (consult factory).

• Sensor readings show -99999 or are unstable.

Suggestions:

1. The wrong sensor type has been selected. Check the model number of the sensor against the software setting (Section E.1).

2. The cable(s) to the sensor(s) have been damaged permitting moisture and debris to enter the jacket. Wires may be shorted together. Inspect the cable.

3. If all sensors on a particular multiplexer are erratic or returning “-99999” perhaps the multiplexer or interface cable has been damaged / unplugged.

4. The sensor(s) have been damaged. For example, overrange on a vibrating wire sensor can cause erratic readings.

5. There is an electrical noise source nearby. Move the sensor, cables, and Datalogger away from the noise source. Install grounding devices. Consult the factory.

• The sensor readings show OVERRANGE all the time.

Suggestions

1. The “Sensor Type” selected for that particular channel is “None”. This is applicable for users of MultiLogger (Section E.1). Please refer to the MultiLogger manual.

2. A scan has not been initiated yet because of the “Start Time” setting (MultiLogger users only).

3. “Update” has not been run (MultiLogger users only).

APPENDIX E –LOGGERNET QUICKSTART GUIDE

E.1 Overview

Campbell Scientific’s LoggerNet Software is used to communicate with the Datalogger, program user specific settings and collect Data stored in the Datalogger memory.

LoggerNet is designed to be used with Geokon Micro-1000 and Micro-800 Dataloggers reading Vibrating Wire and MEMS tilt sensors; other configurations and sensor outputs are available upon request. Geokon provides the user with a generic Start Program to simplify acquiring Data without the need to be proficient in Campbell Scientific CRBasic programming code. The Start Program(s) will be pre-configured with a default Scan

Interval and will store Raw Units by default. Each Start Program will have two associated files on the factory supplied USB flash drive. The first is the Main CRBasic program

(.CR1/.CR8) and includes all programming code required to read and store Data according to the Datalogger configuration. The Main CRBasic program does not require modification by the user in most cases. The second file is the Include (.DLD) text file and is used by the Main program to import user specific parameters. The Include file allows program parameters such as the Scan Interval, Zero Readings, Linear Gage Factors, Data

File Header Labels and Temperature Correction factors to be modified by the user.

E.2 Getting Started

APPENDIX F –8032 MULTIPLEXER Manual

The following Appendix includes excerpts from the Model 8032 Multiplexer manual that apply to the Micro-800. A complete version of the Model 8032 Multiplexer Manual can be found at

WWW.GEOKON.COM

.

THEORY OF OPERATION

The Model 8032 Multiplexer expands the number of channels that can be read by the

MICRO-800 Datalogger or MICRO-1000 Datalogger. Channel switching is accomplished by mechanical relays mounted on the underside of the circuit board and the transducer connections are accomplished by friction locking spring-loaded terminals mounted on the top side of the circuit board.

Two switching configurations are supported, 16 channels of 4 conductors or 32 channels of 2 conductors. For the 8032-C, these configurations are set by a DipSwitch on the top side of the circuit board. A second DipSwitch selects whether the 8032-C is being used with a datalogger or GK-403 Readout Box

To protect against lightning or EMI/RFI induced transients, each channel is protected by an integrated lightning protection system, incorporating 230V tripolar plasma surge arrestors, 150V bipolar plasma surge arrestors, 10uH inductors and 16V transient voltage protection diodes. See Appendix A for complete specifications on these components.

The 16 channel 4 wire switching configuration is typically used to multiplex 4 wire sensors such as resistance strain gage load cells. It is also used to switch connections for instruments which have more than one sensor integral to them, such as vibrating wire pressure transducers with an integral thermistor for measuring temperature.

Figure 2 - 32 Channel Switching Block Diagram

The 32 channel 2 wire switching configuration is typically used to multiplex 2 wire sensors such as a vibrating wire pressure transducers, thermistors or thermocouples.

The multiplexer is powered by a nominal 12 VDC supply. Two control lines (RESET and CLOCK) determine how channel selection is accomplished. Two schemes are supported - one when connected to the GK-403 Vibrating Wire Readout Box and the other when connected to MICRO-800 or MICRO-1000 dataloggers. See the following sections explaining how each mode operates.

Figure 3 illustrates the DIP switch SW1 position 1 for switching between 16 and 32 channel operation. SW1 switch 1 ON = 32 channel, OFF = 16 channel. In Figure 3, 32 channel mode is chosen:

MICRO-1000 / 800 (CR1000 / CR800) Mode of Operation

The MICRO-800 and MICRO-1000 (which respectively utilize a CR800 and CR1000 controller, manufactured by Campbell Scientific, Inc. of Logan, Utah) mode of operation uses two control lines to operate the multiplexer. The RESET line enables the multiplexer and activates the MICRO-800/MICRO-1000 mode of clocking. Pulses received on the CLOCK line sequentially increment the channels while the RESET line is held high. See the timing diagram below;

The CLOCK line sequentially advances the channels beginning with channel 1. Note the timing diagrams below for 16 and 32 channel switching, respectively.

TROUBLESHOOTING

Below are some commonly experienced problems along with possible remedial action.

Contact the factory if any problem remains unresolved or additional help is required.

A particular channel on the multiplexer appears to be malfunctioning.

• Check sensor connections on the terminal board. Clean if corrosion exists.

• Try moving the sensor wired to the suspect channel to another channel to verify the malfunctioning of the channel (as opposed to the sensor).

No channels are working.

• Inspect circuit board for shorts, opens, or other damage.

• Is moisture present on circuit board? If so, install desiccant to absorb.

Channel selection appears to be random.

• Has corrosion built up on the circuit board? Clean if necessary.

• Is there a source of electrical noise nearby? Move multiplexer or noise source if possible.

DAISYCHAIN OPERATION

Up to (8) 8032’s may be ”daisychained” together using a common RESET and CLOCK control line. This may be advantageous in situations where either there are not enough control ports available on the Micro-800/MICRO-1000 datalogger for the number of multiplexers desired, or to reduce the number of cables required to implement a large multi-channel system.

SW1 located on the Terminal Block side of the circuit board determines the address of each multiplexer and the corresponding signal channels. As many as 256 2-conductor channels or 128

4-conductor channels may be accessed per RESET line.

MAXIMUM 8032-5 (TAN CABLE) CABLE LENGTHS

The 8032 Multiplexer is a low power device, that when combined with a Micro-800 or Micro-

1000 Datalogger can be physically located at a considerable distance from that Datalogger.

Still, there are limits to the maximum distance – mostly due to the voltage dropped by the 8032-5

MUX cable over its length. Factors such as ambient temperature, number of 8032 Multiplexers

(Daisy-Chain configuration) and system battery voltage need to be considered in determining the maximum 8032-5 cable length.

For a single 8032 Multiplexer under normal operating conditions (System Battery = 12V, ambient temperature = 20°C), the maximum recommended cable length from the Datalogger to the 8032 Multiplexer is 4588 feet (

≈1400m). Figure E.1 displays the maximum recommended cable length for various Datalogger, Battery Voltage and ambient Temperature combinations.
