6 Module Exchange and Expansion
of the Unit
Danger of explosion!
Working on the device in an explosive atmosphere can lead to
explosions.
O
Make sure that the atmosphere is not explosive if work is
required on the device.
Large differences in potential occur when disconnecting plugs
under voltage, which could result in an explosion in explosive
atmospheres.
O
Never disconnect the device from the power in an explosive
atmosphere.
O
Never loosen the spring clamp elements on the modules in
an explosive atmosphere.
The unit was individually configured according to your
specifications and fully assembled on delivery. You may, however,
exchange bus couplers and I/O modules, and add or remove I/O
modules.
O
Always document all changes to your configuration.
The valve system assembly instructions contain a detailed
description of the assembly of the complete unit.
Module fastening methods
The bus couplers are fastened as follows:

The spring clamp elements are secured in captive connections on
the right side of the I/O modules and the left end plate.
Preparing exchange and extension
1. Make sure that the atmosphere is not explosive if work is
required on the device.
2. Make sure the relevant system part is not under pressure or
voltage.
3. Disconnect the electrical connections on the bus coupler and
I/O modules if required to mount the device.
Danger of injury if unit is mounted in a suspended position.
Parts of the unit may fall down and cause injuries.
O
Support the device before commencing disassembly.

CAUTION
Exchanging the bus coupler
Disassembling the bus coupler
1. Remove the screws used to mount the left end plate to the
mounting surface.
2. Loosen the spring clamp elements, e.g. using a screwdriver,
between the bus coupler and I/O module, or between the bus
coupler and left end plate, and pull them up to the stop
3. If necessary, remove the retaining brackets (
modules.
4. Pull all of the components away towards the left until they are
no longer connected with the bus coupler
5. Loosen the mounting screws (
system: Ejot TORX PLUS®/AUTOSERT® 20IP
6. Pull the bus coupler to the left to remove it from the transition
or end plate.
Mounting a new bus coupler
1. Check the part number on the rating plate to make sure that
you are exchanging the correct bus coupler.
2. Mount the labels from the old bus coupler onto the new bus
coupler or label the equipment ID field (
coupler.
3. Adjust the switches on the new bus coupler in line with the old
bus coupler. Open the window (
are fitted correctly when closing the window.
4. Place the new bus coupler on the mounting surface and slide it
to the right onto the transition plate or the end plate for the
stand-alone variant on
correctly.

5. Insert the three mounting screws into the through holes (
10) on the left side of the bus coupler and tighten the screws.
Tightening torque: 1.5–1.8 Nm with drive system Ejot TORX
PLUS®/AUTOSERT® 20IP
Remounting the I/O modules and end plate
1. At the right side of the previously removed I/O modules, lift up
both spring clamp elements until the stop
2. Place the removed modules on the mounting surface and slide
them to the right onto the unit
inserted correctly.
3. Press down both spring clamp elements until the stop
All modules are now connected to the unit.
4. Retighten the end plate and retaining brackets
(if required) to the mounting surface.
5. Reconnect the electrical connections on the unit according to
the labels.
Exchanging the I/O module
Disassembling the I/O module
1. Remove the screws used to mount the left end plate to the
mounting surface.
2. Loosen all of the required spring clamp elements, e.g. using a
screwdriver, and pull them up to the stop
3. If necessary, remove the retaining brackets (
modules.
4. Pull all of the components away towards the left until they are
no longer connected
5. Remove the desired I/O module.
