Description

Philips LCCII MRI Cooling Service Procedure Document

This 93-page Philips service procedure document is dedicated to the LCCII liquid cooling cabinet used with Intera/Achieva hardware. It covers configuration, electrical programming, cooling-loop setup, testing, adjustments, filling and draining procedures, component replacement, communications, interlocks and faultfinding in one detailed service reference.

Compatibility and Hardware Scope

• Intera / Achieva hardware
• System software R2.6.3 or higher when replacing an older LCC with an LCCII
• Minimum hardware identified in the document: CDAS with Copley 281 / 281+ or Copley 78X gradient amplifiers
• Procedures include specific references for Copley 781 and Copley 787 configurations

Cooling-System Architecture Covered

The manual describes the LCCII as a cooling cabinet with a primary circuit connected to hospital cooling water or a chiller, a direct primary connection for the cryo compressor, and two hydraulically separated closed secondary loops: one for the gradient coil and one for the gradient amplifier. It documents APD HC-8E and Sumitomo F-50/SHI compressor arrangements and 50 Hz/60 Hz configurations.

Programming, Tests and Adjustments

• FSF configuration
• Q1, Q2 and Q3 current settings
• LCCII voltage programming
• APD and SHI cryo-compressor voltage programming
• Pump mains phase-order checks
• LCC board and LCC Info overview tests
• Temperature and pressure checks
• Copying hardware parameters to the LCC
• Resetting gradient-amplifier and gradient-coil pump hour counters
• System startup and standby procedures
• Cryo-compressor primary-water flow checks
• Secondary-flow checks and adjustments

Replacement, Filling and Cooling-Loop Procedures

The largest part of the document is hands-on service work. It covers primary-circuit filling, mains connection, filling-pump use, expansion-vessel pressurizing, gradient-coil circuit filling or water replacement, gradient-amplifier circuit filling, loop draining, pump service, heat exchangers, electronic box, sensors, filters, transformer, hoses and complete LCCII replacement. The GA II filling procedure explicitly notes that it must also be performed for C781 configurations because of the bypass arrangement.

Separate procedures cover installation of primary hoses, gradient-coil hoses and gradient-amplifier hoses, including Copley 781 and Copley 787 connections. The document also gives operational pressure/flow context, pump types for 50/60 Hz and practical restart steps following service.

Faultfinding and Communications

• Controller, GC and GA status displays
• Input/output status LEDs
• RS232 PC-to-LCCII interface
• RS232 IGCI-to-LCCII interface
• Interlock-error status
• LCC Info overview diagnostics
• LCC fault diagnosis
• Service-PC connection and HyperTerminal commands
• Error codes for primary, gradient-coil and gradient-amplifier circuits

This makes the manual useful for both planned component work and active troubleshooting of cooling faults, interlocks, flow problems and LCC communication issues.
