TA561-RTC - Real-time Clock Adaptor

../_images/056b23c8e3878f990a33139000eba54e

Intended Purpose

The TA561-RTC real time clock adaptor is used for equipping AC500-eCo Processor Modules with a real-time clock.

The real time clock can be buffered via an optional standard lithium battery (CR2032) during power supply failures (see lithium battery for real-time clock of AC500-eCo Processor Modules CR2032 - Battery for Real-Time Clock).

Insertion and Replacement of the Adaptor

Warning

:strong:Risk of electric shock!

With an opened option cover, energized parts of the Processor Module could be touched.

  • Always turn off and disconnect the power supply for the Processor Module before you open the option cover.
  • Make sure that die option cover is closed before reconnecting the Processor Module to the power supply.

Insertion/ removal of the adaptor and replacement of the battery is also described in the installation instruction for TA561-RTC. See https://new.abb.com/products/ABB1SAP181400R0001

Click tab Documentation and select Operating Instruction.

The option cover is available as a spare part (see TA570 spare part set for AC500-eCo Processor Modules TA570 - Spare Part Set).

Replacement of the Battery

Warning

:strong:Risk of death by electric shock!

The terminals of the module can carry 240 V voltage.

Make sure that all voltage sources (supply and process voltage) are switched off before you begin with operations at the system.

  1. Switch off power supply of the system and verify that the CPU is powerless.

    ⇒
    ../_images/b13fa624490c9c6a0a317f3432f8ddbd

    LEDs (PWR, RUN, ERR) must be off.

  2. Remove the option cover.

    ⇒
    ../_images/ce7112314914c0dd0a317f3411077519

    Remove the option cover of the CPU totally by pushing it to the outer side.

    Attention

    :strong:Avoidance of electrostatic charging

    PLC devices and equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Observe the following rules when handling the system:

    • Touch a grounded object to discharge potential static.
    • Wear an approved grounding wrist strap.
    • Do not touch connectors or pins on component boards.
    • Do not touch circuit components inside the equipment.
    • If available, use a static-safe workstation.
    • When not in use, store the equipment in appropriate static-safe packaging.

  3. Remove the option board.

    ⇒

    Note

    Remove SD Memory Card (if installed) / terminal block (COM2).

    ../_images/9ea54b5e4924d1360a317f343d8eab44

    Remove the option board from the CPU by lifting it up with a screwdriver.

  4. Remove the battery.

    Note

    :strong:ATTENTION!

    Lithium batteries must not be recharged, not be disassembled and not be disposed of in fire.

    Exhausted batteries must be recycled to respect the environment.

    Dispose of battery properly according to disposal procedures for lithium batteries.

  5. Insert replacement battery.

    Note

    :strong:ATTENTION!

    A standard batterie CR2032 can be used for TA561-RTC and TA562-RS-RTC.

    Nominal voltage: 3 V DC.

    Required capacity: 230 mAh.

    Required temperature range for discharge: 0 … +70 °C.

    After replacement of the battery, the Real-time Clock (RTC) date and time must be set again by the user.

    Don’t use a battery older than 3 years for replacement (e.g. battery kept too long in stock).

    Batteries must be stored in a dry place.

  6. Insert option board into the CPU.

    ⇒
    ../_images/b36ee3ff49633fa70a317f3418cbb923

    Plug the adapter TA56x-RTC to the right expansion slot of the CPU.

    Note

    Make sure that the 2 noses of the expansion module fit to the holes of the CPU PCB.

    See white circle in figure above.

    Note

    Remember to re-insert a SD Memory Card first if it has been removed previously.

  8. Only now the CPU can connected to power.

    Note

    Set the time of the RTC.
