4.0 INSTALLATION AND CONNECTIONS (CONTINUED)
4.6
CUSTOMER INTERFACE CARD A 230 (OPTION)
Terminal strips X1/X2/X30 on the Customer Interface
Board can be used by the customer to match the
equipment to his own electronic installation, such as
emergency stop circuit, remote control signals and so on.
4.6.1
Terminal Strip X1
Terminal strip X1 is used for external emergency
stop, remote control and additional special
signals.
Emergency Stop Circuit
The emergency stop circuit is initially only fitted
internally. If an external emergency stop contact
is to be added, then the links between EPOint
X1.1 and EPOext X1.2 should be removed and
replaced by a normally-closed contact from the
external emergency stop button.
Remote Control Functions/Terminal Strip X1
The “on and off” remote control functions and
additional special signals can be controlled from
a potential-free contact as well as from an
external 24-V signal. The current loading is 13
mA.
These inputs are connected to the controller of
the customer interface card, which transmit the
signal states serially to the system controller. Each signal group has an own earthing. When
using an external 24 V DC voltage, this must therefore also be connected to the external earth.
Otherwise, when using an internal 24 DC voltage, this external earth connection has to be
connected with the internal earth.
These earth connections (links) are already installed ex works and have to be removed if it is
necessary.
The table on the following page shows the remote control functions when potential-free contacts
are used. However, if 24 V DC is used, then the GND should be connected to earth.
