SECTION 3 – MECHANICAL DETAILS
Logic Rack
The 9000TS System is mounted in industry standard 19" Racks manufactured to
IEC297-3 (DIN1494 Pt5). On larger systems multiple racks are supplied and ribbon
cables, which plug into dedicated sockets on the rear of each rack, are used to link
common bus lines.
When mounting the rack care must be taken to ensure that there is sufficient room to
withdraw the cards from the front of the rack and for cable access to the rows of 16
way terminals mounted on the rear of the rack. Customer inputs and outputs are
capable of accepting cable up to a maximum of 2.5mm2 and each terminal block can
be removed for ease of wiring using the locking screws provided at either end of the
block
Mounting
The 19” Rack should be mounted in a location that is free from excessive moisture,
vibration, heat and dust with sufficient clearance at the front to withdraw all cards
without obstruction and space at the rear to connect the associated field wiring. All
spare positions in a rack are fitted with all of the necessary edge connectors and
chassis blanking plates for ease of expansion at a later date. Additional Input, Output
or Relay Cards can therefore be plugged in and connected with ease.
Earthing
To comply with the EMC requirements for electrostatic discharge IEC801-2 it is
essential that each 19" Rack is suitably earthed. A dedicated earth point is supplied on
the right hand side plate of each rack for this purpose.
Plug-in Cards
The first rack in any system is supplied with one P925TS-X Interface Card and thirteen
vacant card slots, which can be used for a combination of :-

Once the cards are plugged into the rack they automatically connect to the
motherboard to link all of the control functions between cards and to provide
connections to the Customer terminals mounted on the rear of the rack.
Lamp / LED Displays
The 9000TS System is able to drive existing displays or RTK can supply the system
with RTK manufactured display units as required.
