OV1. Physical Description

Figure OV1-2 shows the CR5000 panel and the associated program instructions. Unless otherwise noted, they are measurement instructions (Section 7).

OV1.1 Measurement Inputs

OV1.1.1 Analog Inputs

There are 20 differential or 40 single-ended inputs for measuring voltages up to ± 5 V. A thermistor installed in the wiring panel can be used to measure the reference temperature for thermocouple measurements, and a heavy copper grounding bar and connectors combine with the case design to reduce temperature gradients for accurate thermocouple measurements. Resolution on the most sensitive range is 0.67 µ V

CR5000 Overview

OV1.1.2 Signal Grounds ( )

The Signal Grounds ( ) should be used as the reference for Single-ended Analog inputs, Excitation returns, and sensor shield wires. Signal returns from the CAO and Pulse channels should use the located on the CAO and Pulse terminal strip to minimize current flow through the grounds on the analog terminal strips. terminals

OV1.1.3 Power Grounds (G)

The Power Grounds (G) should be used as the returns for the 5V, SW12, 12V, and C1-C8 outputs. Use of the G grounds for these outputs with potentially large currents will minimize current flow through the analog section, which can cause Single-ended voltage measurement errors.

OV1.1.4 Ground Lug

The large ground lug is used to connect a heavy gage wire to earth ground. A good earth connection is necessary fix the ground potential of the datalogger and to send to earth transients that come in on either the G or terminals or are shunted to ground via the spark gaps protecting other inputs.

OV1.1.5 Power In

The G and 12V terminals on the unplugable Power In connector are for connecting power from an external battery to the CR5000. These are the only terminals that can be used to input battery power; the other 12V and SW-12V terminals are out only. Power from this input will not charge internal CR5000 batteries. Power to charge the internal batteries (17-28 VDC or 18 VRMS AC) must be connected to the charger input on the side of the LA battery back.

OV1.1.6 Switched 12 Volts SW-12

The SW-12 terminals provide an unregulated 12 volts that can be switched on and off under program control.

OV1.1.7 Switched Voltage Excitation (VX)

Four switched excitation channels provide precision programmable voltages within the ±5 Volt range for bridge measurements. Each analog output will provide up to 50 mA between ± 5 V.

OV1.1.8 Switched Current Excitation (IX)

Four Switched Current Excitation channels provide precision current excitations programmable within ± 2.5 mA for resistance or bridge measurements.

OV1.1.9 Continuous Analog Outputs (CAO)

Two Continuous Analog Outputs (CAO) with individual outputs under program control for proportional control (e.g., PID algorithm) and waveform generation. Each analog output will provide up to 15 mA between ± 5 V.

OV-3

CR5000 Overview

OV1.1.10 Control I/O

There are 8 digital Input/Output channels (0 V low, 5 V high) for frequency measurement, digital control, and triggering.

OV1.1.11 Pulse Inputs

Two Pulse input channels can count pulses from high-level (5 V square wave), switch closure, or low-level A/C signals.

OV1.1.12 Power Up

The CR5000 allows shutting off power under program control. The Power Up inputs allow an external signal to awaken the CR5000 from a powered down state (PowerOff, Section 9). When the CR5000 is in this power off state the ON Off switch is in the on position but the CR5000 is off. If the "<0.5 " input is switched to ground or if the ">2" input has a voltage greater than 2 volts applied, the CR5000 will awake, load and run the “run on power-up” program. If the "< 0.5" input continues to be held at ground while the CR5000 is powered on and goes through its 2-5 second initialization sequence, the CR5000 will not run “run on power-up” program.

OV1.1.13 SDM Connections

The Synchronous Device for Measurement (SDM) connections C1,C2, and C3 along with the adjacent 12 volts and ground terminals are used to connect SDM sensors and peripherals.

OV1.2 Communication and Data Storage

OV1.2.1 PCMCIA PC Card

One slot for a Type I/II/III PCMCIA card. The keyboard display is used to check card status. The card must be powered down before removing it. The card will be reactivated if not removed.

CAUTION

Removing a card while it is active can cause garbled data and can actually damage the card. Do not switch off the CR5000 power while the card is present and active.

OV1.2.2 CS I/O

A 9-pin serial I/O port supports CSI peripherals.

OV1.2.3 Computer RS-232

RS-232 Port

OV-4

CR5000 Overview

OV1.3 Power Supply and AC Adapter

The CR5000 has two base options the low profile without any power supply and the lead acid battery power supply base. The low profile base requires an external DC power source connected to the Power In terminal on the panel. The battery base has a 7 amp hour battery with built in charging regulator and includes an AC adapter for use where 120 VAC is available (18 VAC RMS output). Charging power can also come from a 17-28 VDC input such as a solar panel. The DCDC18R is available for stepping the voltage up from a nominal 12 volt source (e.g., vehicle power supply) to the DC voltage required for charging the internal battery.

OV2. Memory and Programming Concepts OV2.1 Memory

The CR5000 has 2MB SRAM and 1MB Flash EEPROM. The operating system and user programs are stored in the flash EEPROM. The memory that is not used by the operating system and program is available for data storage. The size of available memory may be seen in the status file. Additional data storage is available by using a PCMCIA card in the built in card slot.

OV2.2 Measurements, Processing, Data Storage

The CR5000 divides a program into two tasks. The

measurement task

manipulates the measurement and control hardware on a rigidly timed sequence. The

processing task

processes and stores the resulting measurements and makes the decisions to actuate controls. The measurement task stores raw Analog to Digital Converter (ADC) data directly into memory. As soon as the data from a scan is in memory, the processing task starts. There are at least two buffers allocated for this raw ADC data (more under program control), thus the buffer from one scan can be processed while the measurement task is filling another. When a program is compiled, the measurement tasks are separated from the processing tasks. When the program runs, the measurement tasks are performed at a precise rate, ensuring that the measurement timing is exact and invariant.

Measurement Task: Processing Task:

Digital I/O task Processes measurements Determines controls (port states) to set next scan Stores data Analog measurement and excitation sequence and timing Reads Pulse Counters Reads Control Ports (GetPort) Sets control ports (SetPort)

OV-5

CR5000 Overview

OV2.3 Data Tables

The CR5000 can store individual measurements or it may use its extensive processing capabilities to calculate averages, maxima, minima, histogams, FFTs, etc., on periodic or conditional intervals. Data are stored in tables such as listed in Table OV2-1. The values to output are selected when running the program generator or when writing a datalogger program directly.

You may use the default directory of PC9000 or install the software in a different directory. The directory will be created for you. To abort the installation, type Ctrl-C or Break at any time.

OV3.3 PC9000 Software Overview

This overview points out the main PC9000 functions and where to find them. PC9000 has extensive on-line help to guide the user in its operation, run PC9000 to get the details. A CR5000 is not necessary to try out the programming and real time display options; a demo uses canned data for viewing. Without a CR5000, there are no communications with the datalogger; operations such as downloading programs and retrieving data will not function. Figures OV3-1 and OV3-2 show the main PC9000 menus. The primary functions of PC9000 are accessed from the File, Comm, Realtime, and Analysis selections on the main menu (Figure OV3-1).

PERIOD AVERAGING MEASUREMENTS

DESCRIPTION: The average period for a single cycle is determined by measuring the duration of a specified number of cycles. Any of the 40 SE analog inputs can be used; signal attenuation and ac coupling may be required.

PULSE COUNTERS

DESCRIPTION: Two 16-bit inputs selectable for switch closure, high frequency pulse, or low-level ac.

MAXIMUM COUNT: 4 x 10 9 counts per scan SWITCH CLOSURE MODE: Minimum Switch Closed Time: 5 ms Minimum Switch Open Time: 6 ms Maximum Bounce Time: 1 ms open without being counted.

HIGH FREQUENCY PULSE MODE: Maximum Input Frequency: 400 kHz Maximum Input Voltage: ±20 V Voltage Thresholds: Count upon transition from below 1.5 V to above 3.5 V at low frequen cies. Larger input transitions are required at high frequencies because of 1.2 µs time constant filter.
