GM Overview and Configuration
The SMARTDAC+ GM Data Acquisition System is a versatile and expandable data logger. The system typically consists of a GM10 Data Acquisition Module, a GM90PS Power Supply Module, and a GM90MB Module Base that houses various GX90 series I/O modules.
The GM can be configured in different system types:
- Single Unit System: Comprises a GM10 and GM90PS. Up to 10 I/O modules can be connected.
- Multi Unit System: Connects a main unit (GM10 + GM90PS) with sub units via GX90EX Expansion Modules. Up to six sub units can be connected, each supporting up to six modules. The maximum connection distance between units is 100 meters.
Modules are installed into the GM90MB. The system configuration requires proper linking of modules and potentially the GX90EX for multi-unit setups.
Module Compatibility and Channel Naming
Ensure that the firmware versions of the I/O modules are compatible with the GM. For example, GX90XA modules require specific firmware versions (e.g., R1.04.01 or later).
Module Limitations:
- There are limits to the number of I/O modules that can be connected per unit, depending on the module types (e.g., GX90XA-10-T1, GX90XA-04-H0, GX90UT).
- Measurement modes (Normal, High speed, Dual interval) affect supported modules and scan intervals. For instance, High speed mode may limit detected modules to GX90XA-04-H0, GX90XD, and GX90WD.
- Specific module combinations or settings (like Dual interval mode) may restrict the use of certain modules (e.g., GX90UT is not detected in Dual interval mode).
Channel Names:
Channels are identified by a 4-digit system-specific name: Unit Number (0 for main, 1-6 for sub) + Slot Number (0-9 or 0-5 depending on system type) + Channel Number (e.g., 01-10, 01-16). Tags can be assigned for user-defined names.
Operating Procedure
The GM system can be operated standalone or via a PC. Configuration and monitoring are typically performed using a PC.
- Module Preparation: Check and prepare all required modules.
- Installation: Install modules into the module base (GM90MB) and assemble the system units (GM10, GM90PS, GM90MB, GX90EX if applicable).
- Wiring: Connect I/O signals and power supply according to the wiring diagrams and precautions.
- Power On: Turn on the power supply.
- PC Configuration:
- IP Address: Use the IP Address Configurator for Ethernet connections.
- Hardware Configuration: Use the SMARTDAC+ Standard Hardware Configurator software for detailed settings via Ethernet, USB, or Bluetooth. This includes setting the measurement mode, date/time, signal inputs, and recording conditions.
- Reconfiguration: Perform reconfiguration after initial setup or when modules are changed to ensure the system recognizes the hardware.
- Start Measurement/Recording: Initiate recording via the Web application, Hardware Configurator, or the START/STOP keys on the GM10 unit.
Communication Methods:
- Ethernet: Direct connection or via a network hub.
- USB: Requires the Hardware Configurator software and a USB driver.
- Bluetooth (/C8 option): Requires pairing and configuration via the Hardware Configurator.
Installation
[CAUTION] Ensure power is OFF before installation.
Installation Location
Install the GM unit indoors in a well-ventilated location, free from excessive dust, moisture, or corrosive gases. Avoid direct sunlight, heat sources, and strong magnetic fields. Ensure minimal mechanical vibration and a level surface. The ambient temperature range is -20 to 60°C (or -20 to 50°C with specific modules).
For safety compliance (CSA/UL/EN 61010-2-201), install the GM unit in a panel with a door, ensuring adequate protection (IP1X, IK09). If hazardous voltages are present, ensure the unit is inaccessible to prevent accidental contact.
Installation Procedure
The GM can be installed in several ways:
- Desktop or Floor: Place the unit upright using the integrated legs on the GM90PS and GM90MB.
- DIN Rail Mounting: Hook the unit onto a DIN rail and secure it by pushing until it clicks. Removal involves releasing a latch.
- Wall Mounting: Secure the GM90PS to the wall using screws, then link GM90MBs to the GM90PS and fasten them. Install modules afterward. Ensure modules are installed upright.
External dimensions and mounting hole details are provided in the original manual.
Wiring
[CAUTION] Ensure power is OFF before wiring. Use appropriate cables and crimp-on lugs with insulation sleeves for secure connections. Avoid applying excessive tension to cables.
Wiring Precautions:
- Use cables rated for at least 70°C.
- Prevent conductive debris from entering the unit.
- For signal cables carrying voltages over 30V AC or 60V DC, use double-insulated cables.
- Take measures to prevent noise, such as separating measurement circuits from power cables and using shielded wires. Ground shields appropriately.
- When using thermocouple inputs with internal reference junction compensation, ensure stable terminal temperature and avoid thick wires that cause heat dissipation.
- Do not apply voltages exceeding specified limits to input terminals; this can damage the instrument.
Terminal Blocks and Covers:
Terminal covers protect against accidental contact and should be reattached after wiring. Terminal blocks can be removed and attached using levers or screws, depending on the module.
Wiring to Modules:
The GM system supports various I/O modules:
- GX90XA (Analog Input): Supports DC voltage, TC, RTD, and DC current inputs. Available with screw terminals or clamp terminals.
- GX90XD (Digital Input): Supports open collector/voltage-free inputs. Features photocoupler isolation and a shared common (COM).
- GX90YD (Digital Output): Relay output (SPDT).
- GX90WD (Digital I/O): Combines digital input (photocoupler isolation) and digital output (relay).
- GX90XP (Pulse Input): Supports DC voltage/open collector inputs.
- GX90YA (Analog Output): Provides DC current output.
- GX90UT (PID Control): For PID control loops, includes DI, DO, AI, and AO terminals.
Detailed wiring diagrams and terminal arrangements for each module type are available in the full user manual.
Communication Connections:
- RS-422/485 (/C3 option): Connect using four-wire or two-wire systems, ensuring proper shielding and grounding.
- USB Port: Connect via a USB 2.0 (mini B type) port for configuration using the Hardware Configurator.
- Ethernet Port: Supports Ethernet communication with status indicators for link and speed.
Power Supply Wiring:
Use a power supply within the specified voltage range (90-264 VAC). Connect power and protective ground using appropriate crimp-on lugs (M4) and insulated sleeves. Ensure the power switch is OFF before wiring and that the protective ground terminal is properly earthed. A dedicated power switch for the GM is recommended.
Turning the Power On and Off
The power switch is located on the front panel of the GM90PS. Before turning on the power, verify that all connections are secure and the GM is connected to the correct power supply.
After turning on the power switch, the GM performs a self-test for a few seconds before becoming operational.
Before turning off the power, ensure the GM is not accessing external storage (SD card).
Connecting GX90EX Expansion Modules
The GX90EX is used to expand the system into a multi-unit configuration. It connects to the main unit (GM10) or sub units via Ethernet STP cables in a cascaded connection.
Dipswitch Settings:
- Master/Slave Operation: Set dipswitch 8 to ON for master I/O expansion when connecting to the main unit.
- Unit Number: Dipswitches 1-4 are used to set the unit number (0-6) for sub units. Unit number 0 is reserved for the main unit.
- Data Rate: Dipswitch 7 can fix the data rate to 10 Mbps.
The 7-segment LED on the GX90EX displays the unit number and error codes. Status LEDs (RDY, MAIN, FAIL) indicate operational status.
Bluetooth Connection Procedure (/C8 option)
To connect via Bluetooth for the first time:
- Ensure the GM10 BT LED is off.
- Press and hold the GM10 USER1 key for at least 3 seconds. The BT LED will turn on, indicating standby mode.
- Perform a pairing operation from your PC. A 6-digit authentication code will appear on both the PC and the GM10's 7-segment LED. Confirm the codes match to pair. A COM port will be assigned.
- Connect to the GM from the PC. The default password is '1234'. The BT LED will blink upon successful connection.
Configuration is then performed using the SMARTDAC+ STANDARD Hardware Configurator.
