2.1.3 Connections

Power supply

"24 VDC" model:

 "+" 24 VDC terminal

Supply voltage input 24 VDC

 "–" 24 VDC terminal

Reference potential of 24 VDC supply voltage

"120 VAC" and "230 VAC" models

 "L1" terminal

Supply voltage input,

depending on model: 120 VAC or 230 VAC

 "N" terminal

Supply voltage input,

depending on model: 120 VAC or 230 VAC

 "+" 24 VDC terminal

Control voltage for "Start" and "Teach" controlling inputs

24 VDC unregulated, output current 0.1 A max.

If an external control voltage is applied, this terminal is not connected.

 "–" 24 VDC terminal

When using the internal control voltage, this terminal must be connected to the "Com"

control inputs terminal.

If an external control voltage is applied, this terminal is not connected.

Note:

Alternatively, "120 VAC" and "230 VAC" models may also be supplied with

24 VDC.

In this case, "L1" and "N" terminals must not be connected.

"+24 VDC" and "–24 VDC" terminals are to be connected as described above

for "24 VDC" model.

Caution

Note:

The secondary voltage (24V) of the 120/230V Versions can be used to supply

the control inputs. It is not allowed to supply other accessories which are located

outside the overall enclosure.

Control inputs

 "Com" terminal

Reference potential for control inputs and selection inputs

 "Start" terminal

An input level of +24 VDC relative to "Com" terminal will trigger a "Start" cycle

(the real scanning process).

 "Teach" terminal

An input level of +24 VDC relative to "Com" terminal will trigger a learning cycle

(the "Teach-in").
