Issue 3 August 1998
Installation and Setup 4 - 15
Circuit Pack
Installation
When replacing a circuit pack or adding a new circuit pack to a
controller that is in service, the circuit pack hardware must first
be set up. (See “Hardware Setup.”)
WARNING
Circuit packs can be damaged by static electricity.
Operators should always be grounded when handling circuit
packs. Connect the grounding wriststrap to the ESD ground
plug on the controller front panel.
To install a circuit pack, simply open the controller front panel,
pull out the drawer, and slide the board along its guide rails into
the proper backplane connectors. For CP1, secure it in place with
retaining screws at the front edges of the display. Backplane
connectors are arranged so that circuit packs cannot be inserted
in the wrong slots. It is not necessary to pull fuses or power down
the plant or controller in any manner to remove or add any circuit
packs in the controller.
NOTE
Early versions of the basic Control Unit, coded 113A, do not
allow full functionality and should not be used in this
controller. Use only the 113B Control Unit.
