Hardware Set Up
535 User's Manual Chapter 4 21
CHAPTER 4
HARDWARE SET UP
Hardware configuration determines the available outputs as well as the type of
input signal. The 535 controller comes factory set with the following:
• All specified modules 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.
Altering the factory configuration of the 535, 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, continue set-
ting up the process as needed.
HARDWARE INPUT TYPES
The Process Variable
The 535 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 s) so
that the system does not apply more
heat.
NOTE: Hardware configuration of the
controller is available at the factory;
Consult a Moore Industries application
engineer for details.
