2408 and 2404 Controller 1-3
INTRODUCTION
Models 2408 and 2404 are high stability, temperature or 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 fixed
hardware build.
The instruments are available as:
• standard controllers - which include a basic 8-segment programmer
Models 2408/CC and 2404/CC
• setpoint programming controllers: Models 2408/CP, P4, CM and
2404/CP, P4, CM
• motorised valve controllers - which include a basic 8-segment programmer
Models 2408/VC and 2404/VC
• setpoint programming motorised valve controllers: Models 2408/VP, V4, VM and
2404/VP, V4, VM
Before proceeding, please read the chapter called, 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 sleeve by easing the latching ears
outwards and pulling it forward out of the sleeve. When plugging the controller back into its
sleeve, ensure that the latching ears click into place in order to secure the IP65 sealing.
