More Information

Overview Manuals Specifications Pair Verification Classic Support Failover Setup

Features:

  • Classic redundant controller: ABB documents PM861A in the Classic lifecycle phase.
  • Paired K02 hardware: The package includes two CPUs, bases, links, terminators, and batteries.
  • Application continuity: Flash storage and the approved recovery process support controlled restoration.
PM861AK02 is the two-controller PM861A package for maintaining a verified redundant AC 800M installation.
Its official kit configuration pairs the processors and baseplates with TK850, TB851, ModuleBus termination, and one backup battery per controller.
A Classic-phase procurement review should address immediate package matching, supported firmware and engineering tools, synchronized backups, tested failover, spare strategy, and future migration.
The PM861AK02 3BSE018160R1 ABB may be available from Apter Power subject to exact-article, condition and sourcing confirmation.

PM861A hardware checks

  • CPU labels: Match both PM861A nameplates and hardware revisions.
  • TP830 pair: Confirm both baseplates and DIN-rail positions.
  • Link parts: Verify TK850 and TB851 against the system drawing.
  • Backup batteries: Confirm one approved battery per controller.

Installed-base planning

  • Software path: Confirm the engineering and firmware releases still used at site.
  • Tested spare: Define a recoverable spare and storage procedure.
  • Documentation: Keep project, network, I/O, and cabinet records current.
  • Migration roadmap: Evaluate modernization without changing the current order scope.

Redundant functional checks

  • Synchronization: Confirm matching firmware and application state.
  • Link diagnostics: Check CEX and RCU communication before testing.
  • Power independence: Verify both controller supply paths.
  • Controlled test: Record switch-over behavior under the site procedure.
Description

How should ABB PM861AK02 be evaluated in its Classic lifecycle phase?
Confirm current support, engineering tools, firmware, tested spares, backups, repair strategy, and a separate long-term migration plan.
How should procurement check an ABB PM861AK02 package without relying on appearance?
Match all controller and accessory nameplates to ABB documentation and the installed redundancy drawing before accepting the offer.
What must match before ABB PM861AK02 controllers synchronize?
Align CPU revisions, firmware, application, hardware tree, network identity, link hardware, supply status, and controller diagnostics.
Why might ABB PM861AK02 fail over but not resume normal redundancy?
Review the returning CPU health, firmware, application synchronization, network and link diagnostics, battery, supply status, and event log.
Can ABB PM861AK02 be replaced by a PM864A or PM866A kit directly?
No direct interchange is assumed. Compare software, resources, hardware interfaces, application conversion, I/O, networks, and validation requirements.
What cabinet and power checks apply to ABB PM861AK02?
Verify both 24 V DC paths, DIN-rail mounting, IP20 protection, ventilation, EMC bonding, temperature, humidity, and cable segregation.
What should a sourcing request for ABB PM861AK02 include?
Send both CPU and accessory nameplates, software and firmware releases, package inventory, quantity, condition, destination, and delivery target.
