Hardware composition and connection

(1) Compatible connector board

Model, type, and purpose

X-CB 014 01 single channel, screw terminal single module screw terminal wiring

X-CB 014 02 redundant, screw terminal dual module redundant screw terminal wiring

X-CB 014 03 Single Channel, Cable Plug Single Module Cable Plug Wiring

X-CB 014 04 redundancy, cable plug dual module redundant cable plug wiring

Mechanical coding: The connector board and module are protected against accidental insertion through wedge-shaped coding, and the coding position follows the X-CB 014 series specifications

(2) System cable

Model: X-CA 011 (LIYCY-TP 18 × 2 × 0.25 mm ²)

Length: standard 8m, 15m, 30m, minimum bending radius: fixed installation 5 x cable outer diameter, flexible application 10 x cable outer diameter

Characteristics: Flame retardant and self extinguishing (compliant with IEC 60332-1-2/-2-2), color coding follows DIN 47100

(3) Wiring method

Single channel wiring: Use X-CB 014 01/03 to directly connect the actuator

Redundant wiring (serial): using X-CB 014 02/04, dual modules installed adjacent to each other, sharing actuators

Closed loop control: AO output → actuator → AI input (such as X-AI 32 01) → processor module, forming a feedback loop

FTA connection: Through X-FTA 002 01/X-FTA 009 02, connect the module to the on-site terminal components via system cables

HART communication: The handheld device is connected in parallel at both ends of the actuator, and the residual error after compensating for communication current fluctuations is ≤ 2% of the full range

Configuration and Operation (Based on SILworX Tool)

(1) Core configuration items

Key parameter description for configuring labels

Module Noise Blanking is activated by default, and the processor module delays response to transient faults

Missing modules in the redundant group of Spare Modules are not considered as faults and are automatically shut down by default

I/O submodule AO16_01 Background Test Error: True=Test Fault, False=Normal

I/O submodule AO16_01 Restart on Error Force the faulty module to restart and self check, default shutdown

The default mapping value for Channels 4mA/20mA is 4.0/20.0, and unused channels should be kept as default

After activating Channels redundancy, it is added to the redundancy group and is turned off by default

Channels status (Channel OK): True=Channel normal, False=Channel fault (output set to 0)

(2) Diagnostic status code

Module Status: 32-bit WORD, such as 0x00000001=module fault, 0x00000010=L1+voltage fault

Submodule Status: For example, 0x00000040=module shutdown due to overcurrent, 0x00000010=temperature threshold 1 overtemperature

Channel diagnosis: supports open circuit detection (OC) and OC Monitoring Defect

​Safety and maintenance requirements

(1) Security protection

ESD protection: Only authorized personnel with ESD knowledge are allowed to operate, and must wear anti-static wristbands. Unused modules must be stored in their original packaging

Fault response: In case of module failure, all outputs should be turned off within 16ms; When there is a channel failure, turn off the corresponding channel group (2 channels), and the Error LED will light up

Ex area use: Additional explosion-proof measures need to be taken to avoid sparks caused by plugging and unplugging loaded connectors

(2) Maintenance and disposal

Verification testing: to be conducted every 10 years, refer to the security manual HI 801 003 E

Operating system update: Use system downtime to load the latest version, modules need to be in STOP state

Repair authorization: Only HIMA company has the right to repair, unauthorized intervention will result in safety function failure and warranty failure

Transportation and discontinuation: Original packaging is required for transportation (to prevent ESD and mechanical damage); Discontinuation requires disassembly from the substrate and disposal according to environmental requirements
