Description

The Honeywell FC-CPCHAS-0001 is a 19-inch rack-mounted Controller Chassis engineered to house and interface the Control Processor modules within the Honeywell Safety Manager system architecture. Installed as the main processing enclosure at the top position of a system cabinet, it provides structural housing and complete backplane interconnection for both redundant and non-redundant Safety Manager controller configurations.

The chassis integrates a specialized controller housing with card guides, quarter-turn module locks, and a integrated controller backplane (CPB-0001). The rear section features a magnetically locked back cover plate that swings upward to expose signal connections and a structured cable-management framework with dedicated horizontal bars for 24 Vdc supply/signals, communication links, and 5V/Watchdog lines. The unit routes internal power distribution—including a diode-decoupled, redundant 5V supply (5V-R) derived from connected power supply units—and interfaces up to four I/O buses, watchdog outputs, system power, and communication lines to field I/O racks and external networks.

Features

• Dual-Configuration Flexibility: Supports both single (non-redundant) and fault-tolerant redundant Control Processor setups within a single standard 19-inch housing.
• Integrated Backplane Architecture: Incorporates the CPB-0001 controller backplane to deliver signal routing, 5V-R diode-decoupled redundant power distribution, and I/O bus connections.
• Structured Rear Cable Management: Features three dedicated horizontal tie-wrap bars to separate 24 Vdc power/signals, communication cables, and low-voltage 5V/watchdog cabling.
• Swing-Up Rear Protection: Magnetically locked rear cover plate swings upward for easy access to backplane connectors during installation and maintenance.
• Comprehensive Expansion Capability: Offers interfaces for up to 4 I/O buses with dedicated terminator sockets (TERM-0001/TERM-0002) and 8 watchdog/power distribution channels (WdP1–WdP8) for downstream I/O chassis connection.
• Dedicated Control Inputs: Includes external Emergency Shut Down (SD) interlock terminals and 3 non-safety 24 Vdc general-purpose inputs (IN1–IN3) for functions such as external clock synchronization.

Applications

• Safety Manager Main Controller Enclosure: Primary processing hub housing Quad Processor Packs (QPP-0002), Universal Safety Interfaces (USI-0002 / FX-USI-0002), Power Supplies (PSU-240516), and Battery & Key Switch Modules (BKM-0001).
• Emergency Shutdown (ESD) Systems: Core chassis housing for ESD logic solvers in process plants, offshore platforms, and refineries.
• Burner Management Systems (BMS) & Fire & Gas (F&G): Central hardware frame for processing high-integrity safety loops and fire/gas monitoring logic.

Installation Guidelines

1. Rack Mounting: Install the Honeywell FC-CPCHAS-0001 horizontally into a standard 19-inch rack cabinet, typically positioned at the top location above the associated I/O chassis.
2. Grounding Verification: Ensure the chassis is bonded to the main cabinet frame ground. Built-in keying pins in the backplane provide chassis ground connection to module housings.
3. Module Insertion: Insert modules (QPP-0002, USI-0002, PSU-240516, BKM-0001) along the top and bottom guide rails through the front opening. Secure each module by tightening the quarter-turn fasteners below the module grips.
4. Blanking Plates: Fit BLIND-CPS plates over unused processor/power supply slots and BLIND-COM plates over unused communication slots to prevent airflow bypass and contamination.
5. Rear Cable Management: Swing open the rear magnetic cover plate. Group and secure cables to the horizontal tie-wrap bars according to voltage levels:
   • Top Bar: 24 Vdc supply and 24 Vdc signal wiring.
   • Middle Bar: System Ethernet and general-purpose communication cables.
   • Bottom Bar: 5V auxiliary and Watchdog distribution cables.
6. I/O Bus Termination: Verify that appropriate bus terminators (TERM-0001 or TERM-0002) are fully seated in all active Term IO bus sockets on the rear backplane.
7. Emergency Shutdown Link: Ensure the factory-installed LINK-SD jumper remains connected across the SD terminals unless an external hardwired Emergency Shut Down contact is wired to the chassis.

Configuration and Commissioning Recommendations

1. Power Supply Redundancy Check: Measure voltage at 5V-1, 5V-2, and 5V-R backplane test terminals. Confirm that 5V-R remains energized when either power supply module (PSU1 or PSU2) is operational.
2. Communication Verification: Verify link activity on RJ45 ports (COM1.1–COM2.2) when connected to system switches or downstream Safety Manager networks.
3. Interrupt & Clock Sync Verification: If using IN1 for clock synchronization, verify rising-edge signal integrity and line voltage levels before enabling software interrupts.
