    Unused slots in the System 10/20 chassis are populated with blanking plates to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals.

    1. Logic Test: Checks all logic including on-board microprocessor, relay drivers etc. Note: In the unlikely event of a relay needing replacement additional relays are available from Pickering Interfaces. Self-Test Operation Self-Test is always run at power on. If self-test is run under software control it will firstly clear the whole matrix (Manual Test will only function when the module is in a clear state).
