Mechanical installation
LOCON 7 and LOCON 9 are designed for DIN-rail mounting .
3.5
Electrical installation
The complete electrical wiring of the basic device LOCON is carried out via the 18 pol. screw-
plug-connection on the front side.
3.5.1
Connecting the supply voltage
The supply voltage is 18..28V DC (typ. 24V DC) and is wired according to chapter "Connection
elements".
Before switching on the supply voltage the corresponding inputs and outputs have to be wired, to
avoid malfunctions.
3.5.2
Connecting inputs and outputs
As signal encoder of the machine SSI-, pulse- or incremental-encoders are used. They are con-
nected to the pins 1 - 4 (see pin assignment).
The output pins 7 - 14 of LOCON 7/9 are plus-switching 24V; that means an active output has a
level of 24V compared with GND, a deleted output is high-ohmic.
The outputs are short-circuit-proof and can drive max. 300mA, at which point the 8 outputs may
only be loaded with max. 1A.
In case of a permanent short-circuit or an overload the corresponding outputs are switched off,
the error-LED flashes, and a corresponding error message is shown on a connected display.
3.5.3
Connecting the external program selection
The pins "Program selection 1" and "Program selection 2" have to be wired only, in case the
external program switch (e. g. via PLC) shall be made. Please note that a program shift is carried
out with every change on the input pins; that means, if a program is chosen via the plugs, the sig-
nals "Program-selection 1" and "Program-selection 2" must be held on the respective level, until
a new program selection shall be made.
