3 Installation
20 Festo – P.BE-CPX-CTEL-EN – 1411a – English
Mounting
Mount the module as follows:
1. Check seal and sealing surface.
2. Insert module into the interlinking block. Make sure that the corresponding slots with the contacts
on the bottom of the module lie above the contact rails.
3. Push the module carefully and without tilting into the interlinking block up to the stop.
4. Screws should only be tightened by hand. Screws must be set so that the existing self-cutting
threads can be used.
5. Tighten the screws with a TORX screwdriver, size T10 with 0.9 ... 1.1 Nm.
Dismantling
Dismantle the module as follows:
1. Loosen screws with a TORX screwdriver, size T10.
2. Pull module carefully and without tilting away from the contact rails of the interlinking block.
3.3 I-port connecting cables
Note
Malfunction due to impermissible cabling.
To connect the I-port devices to the CTEL master module, use only the special I-port
connecting cables from Festo (
è
A.3).
The maximum length of the I-port connecting cables used to connect the I-port
devices is limited to 20 m.
You will then avoid errors in data exchange between the CTEL master module and the
connected devices.
For an operation with tool change, there are special specifications that must be observed
in designing the connection lines.
The interface in the connecting cable must be constructed so that, when creating the
connection, the contacts of the device supply voltage (24 V PS and 0 V PS) are energised
first.
Otherwise, a short circuit might be reported temporarily through the voltage present on
the C/Q cable when the connection is created.
