CHAPTER 4
HARDWARE SET UP
Hardware configuration determines the available outputs as well as the type of
input signal. The 535-PROF controller comes factory set with the following:
•
All specified module and options installed (for details, refer to the Order Code
in Chapter 1).
•
Process variable and remote setpoint set to accept a milliamp input
•
Relay outputs set to normally open.
Alter the factory configuration of the 535-PROF, requires accessing the circuit
boards, and locating the jumpers and output modules (see
Figure 4.1).
1. With the power off, loosen the four front screws, and remove them.
2. Slide chassis out of the case by pulling firmly on the bezel.
A detailed view of the circuit boards appears in
Figure 4.2.
After configuring the hardware, or if no changes are necessary, continued set-
ting up the process as needed.
HARDWARE INPUT TYPES
The Process Variable
The 535-PROF accepts several different types of process variable signals. Set
a jumper location to specify the type of input signal. Set the signal range in the
software (see Chapter 5 for software menus, or Chapter 7 for applications).
The jumpers for the process variable are located on the Microcontroller Circuit
Board (see
Figure 4.2). The factory default is Milliamp. Locations are marked
as follows:

NOTE:
Thermocouple downscale and
upscale burnout offers a choice in
which direction the controller would
react in the event of thermocouple
failure. For example, in heat
applications, typically, it is desirable
to fail upscale (TC ) so that the
system does not apply more heat.
