  • Industrial Bakery Allen Bradley PLC 5 Upgrade

    Non Supported Hardware required upgrading from PLC5 hardware to Allen Bradley Control Logix.

    The architecture of the original system was distributed across a local PLC 5 rack containing High speed counter card, analog and digital IO, DH+ Networks for HMI and PLC communications and RIO networks for 11 x field racks. HMI's connected to the system included 2 x PanelView Plus (Ethernet), 1 x PV 550 (DH+). Communications to other PLC's included SLC & Micrologix.

    This system was upgraded over 2 weekend shutdowns to reduce impact to production.

    The final system comprised of an Allen Bradley L71 processor, high speed counter card, and dual Ethernet cards, with local IO, Flex IO remote racks on Ethernet, and ControlNet with analog and digital IO. HMI's were reprogrammed to access the new L71 processor. The PLC code was translated to Logix 5000. Additional PanelView Plus 600's were installed to replace redundant local displays.

    The project was successfully completed with no downtime attributed to the project works.

  • MCC Replacement

    Our customers brief called for replacement of an ageing MCC and supply cabling used to power 'debarking' machinery in their timber mill.

    New electrical control panels required to upgrade the existing MCC were built at Pro-Built Controls premises prior to transporting to site.

    The project works included;

    • Complete all trenching work to accommodate the new supply including trench depth of 1500mm covered with "Quarter minus" screening compacted and covered with and additional 150mm of reinforced concrete and backfilled with remaining earth.
    • Supply and install new 150mm underground conduit (80mtr).
    • Supply and install new 100mm conduit for future cabling (40m).
    • Supply and install new 185mm 4C & E orange circ cable or equivalent.
    • Supply and install new 630 Amp MCCB bucket for the MCC 10.
    • Terminate test and energize the new supply.
    • Manufacture 4 bay distribution centre to replace the existing MCC & feeds to 16 plant items.
    • Remove existing MCC at planned shutdown (2 -3 Days)
    • Test and wire new distribution system prior to delivery
    • Supply and install 6 fortress key locks to existing guarding in the field.
    • Supply and install new fortress master key and key release system.
    • Incorporate one lockable 630 amp Circuit Breaker for single point of isolation.
    • Test and commission.
    • Create CAD electrical schematics and as built drawings

    Installation on the eve of Xmas shutdown, commissioning commencing Boxing Day.

  • Paper Machine DCS Upgrade

    Project requirements - project management, design, install and connect a DCS system to replace dated Siemens S5 and Taylor MOD systems to ABB AC800xA hardware.
    The installation was designed in parallel with the existing legacy system enabling full FATs and minimal disruption to production schedules.
    All new multicore cables were installed from the final point of field connection to MCC Marshalling panels where the IO was connected to multiple controllers depending on the machine process, prior to change over all new connections were tested from the final point of connection back to the respective controller verifying correct operation of each I/O.
    Installation included a new communications network linking all controllers via local Profi-Bus connections through converters to fibre and remote connections, additional server racks were also installed and connected to the DCS network via CAT5 cable.
    Testing included analog I/O and application of a process meter to ensure correct scaling.

  • Bakery Roll Line Control System Upgrade

    This project presented a number of unique challenges for our engineering team including a 48 hour changeover window, missing data & CAD files and insufficient scope documentation. Our engineering staff recreated scope documentation as a forerunner to building, installing and integrating a new control system to suit operational requirements. Integration of the new control system necessitated reverse engineering existing control and equipment function, hardware consisted of approximately 300 I/O utilising an Allen Bradley Compact Logix system coupled with a PV+1500 colour touch screen. System design and layout required conforming to our customers current standards whilst ensuring all applicable industry and regulatory requirements were maintained.

  • Fire Damaged Electrical Cable Restoration

    Fire had caused significant damage to electrical control & power cabling located in underground conduit & ducts.
    Pro-Built Control attended an emergency call out to bypass damaged wiring and install temporary power & control. Project restoration works necessitated reverse engineering system operation requirements and associated process control elements.
    All field, control and power wiring was traced from point to point to develop working schematics prior to rebuilding/rerouting cable runs.
