• Installation and maintenance should only be performed by qualified personnel.
• Ensure the power supply is disconnected before making any electrical connections.
• Verify correct wiring according to the connection diagrams to prevent damage.
• Do not operate the device in environments exceeding its specified operating conditions.
• Protect the device from moisture, dust, and extreme temperatures.

3. Product Overview

The Z109REG2-H is a compact, DIN-rail mountable universal converter. It features clearly labeled terminal blocks for inputs, outputs, and power, along with status indicators on the front panel.

3.1. Front Panel and Connections

Figure 1: Front view of the Logicbus Z109REG2-H Universal Converter. This image displays the device's compact black housing, designed for DIN rail mounting. Visible on the front are two sets of screw terminals, labeled 1-3 and 13-16 at the top, and 7-9 and 10-12 at the bottom. Between these terminals, three LED indicators are present: 'PWR/TAL' (Power/Talk), 'ALARM', and 'COM' (Communication). The model number 'Z109REG-H' is also clearly printed on the lower half of the device's front face.

The front panel includes:

• Terminal Blocks: Numbered 1-3, 13-16 (top) and 7-9, 10-12 (bottom) for various input, output, and power connections.
• PWR/TAL LED: Indicates power status and communication activity.
• ALARM LED: Illuminates when an alarm condition is detected.
• COM LED: Indicates communication status.
• Model Number: Z109REG-H, identifying the device.

4. Setup

4.1. Mounting

The Z109REG2-H is designed for DIN rail mounting. Securely attach the device to a standard DIN rail in a suitable enclosure, ensuring adequate ventilation and clearance for wiring.

4.2. Wiring

Refer to the specific wiring diagrams provided with your product documentation for detailed connection instructions. General wiring principles are as follows:

• Power Supply: Connect the 85-265 V AC/DC power supply to the designated terminals. Ensure the power source matches the device's requirements.
• Input Signals: Connect your analog sensor (e.g., current, voltage, thermocouple, RTD, potentiometer) to the universal input terminals. The device supports 2-wire sensor powering (20 Vdc stabilized, 20mA max with short-circuit protection).
• Output Signals: Connect the standard mA/V output signals to your receiving device (e.g., PLC, DCS).
• Digital Contact: The relay (SPST) output can be configured as an ALARM or STROBE contact. Connect as required for your application.

4.3. Configuration

The Z109REG2-H offers multiple configuration methods:

• DIP-Switches: Basic configuration for input type, START-END scale, output mode (zero elevation, scale inversion), and output voltage type (mA or V) can be set using the internal DIP-switches. Consult the product datasheet for switch settings.
• PC Software: For advanced configuration, connect the device to a PC. The software allows programming of beginning and end scale, additional input types, square root extraction, filter settings, burn-out detection, and relay output parameters.
• Handheld Device: A compatible handheld device can also be used for field configuration.

5. Operating Instructions

Once properly installed and configured, the Z109REG2-H operates automatically.

• Power On: Apply power to the device. The PWR/TAL LED should illuminate, indicating normal operation.
• Monitoring: Observe the ALARM LED for any fault conditions or out-of-scale readings. The COM LED indicates communication activity during configuration or data exchange.
• STROBE Input: If configured, the STROBE input can be used to activate the analog output on a PLC command, providing multiplexing capabilities.

6. Maintenance

The Z109REG2-H is designed for minimal maintenance. Regular checks include:

• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Connection Integrity: Periodically check all wiring connections for tightness and signs of corrosion.
• Environmental Conditions: Ensure the operating environment remains within specified temperature and humidity ranges.

7. Troubleshooting

If the device is not functioning as expected, consider the following troubleshooting steps:

• No Power (PWR/TAL LED off): Verify the power supply connections and voltage. Check for blown fuses in the power circuit.
• Incorrect Output Reading:
  • Check input sensor wiring and functionality.
  • Verify DIP-switch settings for input type and scale.
  • Confirm PC software configuration parameters (scale, filter, burn-out).
  • Ensure the output receiving device is correctly configured and calibrated.
• ALARM LED On: This indicates an out-of-scale condition or a setting error. Review input signal range and configuration settings.
• Communication Issues (COM LED): Ensure correct communication cable connection and PC software settings.

If problems persist, contact technical support.
