8. Chassis Compatibility: Designed exclusively for T8100 chassis, ensuring seamless integration with Trusted system components.

Application Overview

• Fire and Gas Control: Reliable processing of fire and gas detection signals for timely alarm and control actions.
• Emergency Shutdown Systems (ESD): Core processing for emergency shutdown triggers, ensuring rapid response to hazardous conditions.
• Turbine Control: Precise control and monitoring of turbine operations in power generation and industrial plants.
• Industrial Monitoring & Control: Central processing for analog/digital I/O data, enabling comprehensive system monitoring and control.
• Critical Safety Systems: Any application requiring SIL 3 safety integrity, where system failure could lead to safety hazards, production losses, or environmental damage.

Module Configuration

1. Updater Section:
   • Auto Protect Network Variables: Configures the system to use a reduced Modbus Protocol map (see PD-8151B for details).
   • Inter Group Delay: Equates to the Modbus update cycle (default 50 ms), adjustable in 32 integer ms increments (e.g., 33 = 64 ms, 64 = 64 ms). Adjustments have minimal benefit if the application scan time exceeds 50 ms.
2. Security Section:
   • Configures a password for system interrogation via Windows-based HyperTerminal or similar terminal programs, set by selecting "New Password" and entering the password twice.
3. ICS2000 Section:
   • Applies only to Trusted Systems connected to an ICS2000 system via a Trusted to ICS2000 Interface Adapter, allowing selection of data sources for three mimic tables (contact supplier for details).

Installation Guide

Preparation Steps

1. Gather necessary tools: screwdriver, torque wrench, and cable cutter.
2. Inspect the T8110B module for transportation damage (check housing, connectors, and front panel indicators).
3. Verify compatibility with the T8100 chassis (exclusive compatibility) and confirm the module model (ICS Triplex T8110B) matches application requirements.
4. Prepare the 20-32Vdc power supply and communication cables, ensuring they meet the module’s electrical specifications.
5. Ensure the T8100 chassis is powered off and properly grounded before installation.

Mounting

1. Locate the left slot of the T8100 Processor chassis (default slot for the T8110B processor).
2. Align the module with the chassis guide rails and slide it into the slot until it clicks into place.
3. Secure the module to the chassis using the provided mounting screws, tightening to the recommended torque to ensure stability.
4. Ensure adequate ventilation around the module (critical for heat dissipation, as the module dissipates 80W) — maintain a minimum 10cm clearance from other components.

Wiring

1. Power Supply Wiring: Connect the 20-32Vdc power supply to the module’s dedicated power terminals, ensuring correct polarity to avoid damage.
2. Inter-Module Bus Wiring: Connect the module to the triple redundant Inter-Module Bus (for communication with I/O modules), following the chassis wiring diagram.
3. Communication Ports Wiring: Connect external devices to the RS422/485 ports (configurable as 2 or 4 wire) and RS232 diagnostics port as needed.
4. Time Synchronisation Wiring: Connect IRIG-B002/122 time synchronisation signals to the dedicated terminals for precise time stamping.
5. Shielding: Use shielded cables for all communication and signal wiring, connecting the cable shield to the module’s ground terminal to prevent electromagnetic interference.

Testing & Configuration

1. Power on the T8100 chassis and the T8110B module. Check the front panel status indicators to confirm normal operation (green = healthy, no fault lights).
2. Connect a terminal or PC to the front panel RS232 diagnostics port to verify system communication.
3. Load the System.INI configuration file (per PD-T8082) and use the System Configurator to set port options, IRIG time sync, and security settings.
4. Test fault handling by simulating a processor discrepancy; confirm the module automatically detects and handles the fault without nuisance alarms, and the fault is logged in the time-stamped fault historian.
5. Verify SOE buffer functionality by triggering test events and confirming they are transferred to the CI buffer (1000 SOE events → 4000 CI buffer events).

Usage Notes

• The T8110B is exclusively compatible with the T8100 chassis — do not attempt to install it in other chassis models.
• Ensure adequate ventilation to manage 80W heat dissipation; insufficient cooling may cause overheating and module failure.
• Do not exceed the 20-32Vdc voltage range or 80W maximum load, as this may damage the module.
• Hot replacement is supported, but ensure proper safety procedures are followed (e.g., de-energize the module slot) before swapping.
• Regularly check front panel indicators and use the RS232 diagnostics port to monitor module health and log faults.
• The System.INI configuration file is critical for proper operation — ensure it is correctly configured per PD-T8082.
• Only use the T8110B in applications that meet its SIL 3 safety integrity requirements; consult the certification documents for details.
