Installation

Unpack and inspect contents. Mount on DIN rail or flat surface.

Mounting: Secure to DIN rail (EN 50022) using clip; ensure proper ventilation.
Power connection: Connect 24V DC to power terminals observing polarity.
Sensor wiring: Connect sensors to appropriate input terminals.
Output wiring: Connect relay outputs to controlled devices.
Communication: Connect RS-485 or Ethernet cable as required.

WARNING! Disconnect power before wiring. Ensure proper grounding to prevent electrical shock.

First-Time Setup

Apply power; follow initialization sequence.

Power on: Connect 24V DC; controller performs self-test.
Basic configuration: Press PROGRAM to enter setup; navigate with UP/DOWN.
Set measurement units: Select appropriate units for each input channel.
Configure alarm thresholds: Set high/low limits for each monitored parameter.
Set communication parameters: Configure Modbus address and baud rate.
Save configuration: Press ENTER to save and exit setup mode.

CAUTION! Verify wiring before applying power. Use appropriate wire gauges.

Default password: 0000. Change in SYSTEM > SECURITY menu.

Connecting Devices

Sensors: Connect to appropriate input terminals. Outputs: Connect to relay terminals. Communication: RS-485 daisy-chain or Ethernet direct.

Turn off power before connecting devices.
Use shielded cables for analog signals; ground shield at one end.
For RS-485: Connect A to A, B to B; terminate with 120Ω resistor at ends.
For Ethernet: Use standard CAT5e or better cable.

Tip: Label all wires for easy identification during maintenance.

Operating Modes

Supports normal monitoring, calibration, and diagnostic modes.

Normal operation: Displays real-time values; triggers alarms when thresholds exceeded.
Calibration mode: Access via hidden menu (PROGRAM + ENTER for 5 seconds).
Diagnostic mode: Displays system status, error logs, communication statistics.
Data logging: Stores min/max/average values (configurable interval).
Manual override: Force relay states for testing via OUTPUT TEST menu.

WARNING! Calibration should be performed by qualified personnel only.

Advanced Features

Mathematical functions: Scaling, linearization, totalization. Communication: Modbus mapping for all parameters. Security: Password protection for configuration changes.

Care & Maintenance

Disconnect power before maintenance. Clean with dry cloth; ensure ventilation slots remain clear.

CAUTION! Do not use solvents or abrasives. Check connections periodically for corrosion.
