2.1 Planning

our Installation
Preparing
the site for installation of your TI545/TI555 controller consists of
the following tasks.
•
Defining control requirements
•
Determining the number of controllers needed
•
Determining the panel and grounding layout
NOTE:
Since no two applications are identical, use these recommendations
as general guidelines only
.
Use the following steps to define your control requirements:
•
Define the number and type of inputs and outputs you need.
•
Calculate the number of I/O modules and bases that you need.
•
Determine the power requirements and mounting space needed.
•
Consider availability of space (including growth potential). This is
particularly true if several double-wide modules are needed.
Calculate a power budget for each base prior to installation. The power
requirements of all modules must be included in the calculations — the
controller
, the base controllers, as well as the I/O modules. The
user
-supplied power to individual modules is not a part of the power budget
calculation. Refer to Appendix B for Series 505 module power consumption
information.
T
o help ensure reliable system operation, the total power required for the
controller and I/O modules must not exceed the total power available from
the system power supply
. Refer to Chapter 3 for Series 505 power budget.
