9.1. Replacing modules
CAUTION
Risk of damage to equipment or malfunction as a result of uncontrolled machine stop.
Ì The communication within the system is interrupted by the replacement of a module. If a process
is running, this situation can result in an uncontrolled stop and damage to the installation or the
product. Before replacement make sure the installation is in a suitable operating status.
The interlocking/locking module can be replaced only in combination with an overall system restart. On the disconnection
of the module connection, the system enters into a fault state. The related module and all downstream modules remain
inactive until the overall system is restarted (fault state).
9.2. Mounting submodules
CAUTION
Risk of damage to equipment or malfunction as a result of incorrect connection or a conguration
change.
Ì It is only possible to use submodules of connection types P, K and N. Check the compatibility be-
fore installation. For information on the related connection type of a submodule, please refer to the
sticker on the rear of the submodule or the data sheet for the related submodule. This is included
with each submodule.
Ì Pay attention to the alignment of the submodule. See marking (a) in Figure 10: Mounting submod-
ule. Submodules can also be installed rotated by 180°. The marking (a) always indicates the rst
position to be equipped. In the example, the emergency stop S1 is underneath.
Ì Make sure the pins on the submodule slide straight into the guide. Tighten the cover screws to 0.5
Nm.
Ì If you use a submodule, pay attention to the correct alignment of the modules in relation to the
labeling elds on the connection module. Incorrect assignments can cause serious malfunctions in
your installation.
Ì Make sure no foreign bodies, e.g. chips or wire enter the open slots on the submodule. These can
cause short circuits or contact problems.
Ì Avoid touching the contacts on the underside of the submodule. Risk of ESD damage and contact
problems due to soiling.
Ì Unused submodule slots must be tted with a cover (e.g. order number 126372).
