Overview Manuals Fault Isolation Circuit Architecture Replacement Application
  • Legacy two-channel plug-in module for ABB / Hartmann & Braun Contronic systems
  • Channel 1 and 2 status groups with visible Us, Uv, and Uz markings
  • Front-access protection components and a rear multipin rack connector

LZ02 is an ABB / Hartmann & Braun plug-in control and interface module associated with the Contronic system family.

The module provides two visibly identified channel sections, front status indication, accessible protection components, populated electronic circuitry, and a rear interface for connection to the installed rack.

Before installation or replacement, verify the complete part-number suffix, rack position, rear connector, channel wiring, recorded indicator states, front-component ratings, supply requirements, and applicable cabinet drawings.

Availability, condition, price, and shipping time for LZ02 are confirmed during quotation.

  • If both channels show the same fault, check the common cabinet supply, module seating, and rear connector
  • If only one channel is affected, inspect its field wiring, front-access component, and associated circuit path
  • Compare channel measurements with the cabinet drawings before determining that the LZ02 board has failed
  • The LZ02 board uses a two-channel layout with repeated logic and interface sections
  • Its circuitry includes DIP integrated circuits, resistors, capacitors, and discrete semiconductor components
  • The predominantly through-hole circuit design routes both channel sections to the rear rack interface
  • Record the channel 1 and 2 indicator states and front-component positions before removal
  • Match the complete LZ02 suffix, rack position, rear connector, and circuit-board configuration
  • Verify cabinet wiring and the applicable Contronic drawings before restoring power
  • Like-for-like replacement in an existing LZ02 position within a Contronic rack
  • Maintenance of documented two-channel status and interface functions in legacy Contronic cabinets
  • Restoration of the associated channel 1 and channel 2 signal paths after module failure
Description
ABB LZ02 is a H&B Contronic Control/Interface Module. ABB LZ02 is a Hartmann & Braun Contronic plug-in control/interface module with two-channel front indicators, three accessible protection/control caps and a rear rack connector.

For replacement work, confirm the complete model identity, installed slot or mounting context, connector and terminal arrangement, power requirements, configuration and site drawings before energization.

Apter supports legacy automation spares, technical cross-reference and replacement planning. Availability and configuration should be confirmed against the installed unit.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can LZ02 be installed as a direct replacement in an existing Contronic rack?
Use LZ02 only for like-for-like replacement after confirming the complete part-number suffix, rack position, rear connector, channel arrangement, front protection components, and installed system drawings.
Are all 0776067-series versions of LZ02 interchangeable?
Do not assume interchangeability. Compare the complete suffix, circuit-board population, front-panel arrangement, connector configuration, and cabinet documentation before substituting one version for another.
What should be recorded from LZ02 before removing the installed module?
Photograph and record the channel 1 and 2 indicator states, front-cap positions, complete suffix, rack slot, rear-connector orientation, and associated cabinet wiring references.
Can the front protection components on LZ02 be replaced with any equivalent part?
No. The visible M3.15E marking does not fully establish the required electrical characteristics or circuit assignment. Use only components confirmed by the installed documentation or the original part markings.
Does LZ02 require programming before installation?
No standalone programming requirement has been confirmed. Preserve the original rack assignment, channel arrangement, front-component configuration, and any system-level settings associated with the installed module.
What should be checked if LZ02 does not operate correctly after installation?
Check module seating, rear-connector engagement, rack position, suffix compatibility, cabinet supply, front protection components, channel wiring, and the complete indicator pattern before suspecting a board fault.
How should LZ02 be tested after replacement?
Restore power under the site procedure, check the channel 1 and 2 indications, verify the associated Contronic functions, and complete the required signal and system tests before returning the equipment to service.
