Introduction

Model AACC 2000’s are high stability, process controllers with self and adaptive tuning. They have a modular hardware construction which accepts up to three plug-in Input/Output modules and two interface modules to satisfy a wide range of control requirements. Two digital inputs and an optional alarm relay are included as part of the standard hardware.

Before proceeding, please read the, Safety and EMC Information.

Controller labels

The labels on the sides of the controller identify the ordering code, the serial number, and the wiring connections.

Appendix A, Understanding the Ordering Code, explains the hardware and software configuration of your particular controller.

MECHANICAL INSTALLATION

To install the controller

1.Prepare the control panel cut-out to the size shown in Figure 1-3, or 1-4.

2.Insert the controller through the panel cut-out.

3.Spring the upper and lower panel retaining clips into place. Secure the controller in position by holding it level and pushing both retaining clips forward.

Note: If the panel retaining clips subsequently need removing, in order to extract the controller from the control panel, they can be unhooked from the side with either your fingers, or a screwdriver.

Unplugging and plugging-in the controller

If required, the controller can be unplugged from its case by easing the latching ears outwards and pulling it forward out of the case. When plugging the controller back into its case, ensure that the latching ears click into place in order to secure the IP65 sealing.
