Safety information
The documentation contains the information needed to assemble the controller CECX-K-
D1.
Knowledge and proper implementation of the information contained in the documentation
is a prerequisite for successful planning and safe installation, commissioning and mainte-
nance of control systems. Only qualified personnel have the necessary expert knowledge
to be able to correctly interpret and implement the instructions contained in these docu-
ments.
The documentation cannot take into account every conceivable application. Should you
require further information, please request it from your local Festo branch.
Follow the accompanying documentation for your diagnostic module when performing
installation, commissioning and maintenance.
The documents are intended for qualified personnel. These are people who have perti-
nent knowledge in the sphere of automation technology appropriate to their area of activ-
ity.
Safety information on handling
The modules used in the system are sensitive to electrostatic discharge in dismantled
condition.
Caution
Intervention in the device by unqualified people can cause the ma-
chine/system to malfunction as well as bodily injury or damage to
property.
Make sure that only qualified personnel intervene in the device.
Protect all modules with front power supply using a fuse in se-
ries. This fuse must not exceed 10 A under any circumstances.
Caution
Inappropriate handling can result in damage to the modules.
Do not touch any components.
Observe the handling specifications for electrostatic sensitive
devices.
To protect the components against discharges of static electric-
ity, discharge yourself of static electricity before installing or

Safety instructions on designing
Caution
Intervention in the device by unqualified people can cause the ma-
chine/system to malfunction as well as bodily injury or damage to
property.
Note the following information:
-Observe the safety information in the further documentation for your diagnostic mod-
ule.
-The instructions contained in the documentation must be followed exactly at all times.
Otherwise safety hazards may be created or safety equipment integrated in the device
may be rendered ineffective.
-The appropriate safety and accident prevention regulations for the respective applica-
tion must be observed irrespective of the safety information provided in these manu-
als.
-Design the load supply and the operating voltage supply as a limited-power circuit as
per IEC/DIN EN61131−2 and always ensure fuse protection of max. 10 A.
-The 24 V supply to the devices must be ensured through reliable isolation of the low
voltage from voltages that are dangerous to touch.

Product version of the controller CECX-K-D1
The diagnostic module undertakes status monitoring of a pneumatic system for early de-
tection of malfunctions. As part of this process, pressure and flow rate values are continu-
ously recorded and the cycle consumption calculated. These values are compared with
stored reference values. Values exceeding the tolerance range are immediately signalled.
To construct a diagnostic module, you will need the following:
Component
Description
Controller CECX-K-D1
The diagnostic controller controls the diagnostic module (Festo Energy Moni-
toring).
Sensors (flow rate and
pressure)
Sensors record the measured variables and send them as measurement data
to the controller, which processes and makes available the data.
Visualisation (Front End
Display FED or VIPWIN)
The visualisation system or the Front End Display displays and archives the
diagnostic data. It can also be used to change the parameters of the diagnostic
module.

1.2 Controller structure
The controller has a modular structure. It essentially consists of:
-a central module,
-optional modules (in plug-in slots in the central module),
-peripheral modules (installed to the right of the central module).
1.2.1Central module
The central module is the centrepiece of the controller CECX-K-D1. It provides the neces-
sary resources for executing the application software (processor, RAM, etc.).
The central module offers three slots for optional modules that offer further connections
for interfaces to the central module. Three peripheral modules for extending the function
are installed on the right side of the central module.
