  • Page 20: Installation

    Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.

  • Page 21: Hardware Installation

    For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

    MODULE ARCHITECTURE 40-290-021 The 40-290-021 Module utilises 32 SPST relays. In the default state, all relay signal paths are open circuit and all resistors are linked in the chains. Energising a particular relay creates a signal path between the C and A terminals of the relay and short circuits the corresponding resistor.

  • Page 34: Maintenance Information

    For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.

    SECTION 7 - MAINTENANCE INFORMATION pickering CALIBRATION The 40-290 and 40-291 have no user adjustable components. In most applications regular calibration is not required; however for applications where a routine calibration is required for a system we suggest the following functional test for the module.
