VideoJet 400
All four alarm inputs are metallically isolated from the other com-
ponents of the
VideoJet 400
via optocouplers and require a
DC voltage of 5 to 12 V for switching.
If a metallic isolation is not required, the operating voltage of the
VideoJet 400 is alternatively available at the input marked
+5V (up to max. 5 mA).
If necessary, a floating NO contact or push-button can be con-
nected to this input.
If a floating NO contact is used, the c5V must be connected
to the corresponding INPUT connection. The signal generator is
then connected between the other contact of the INPUT connection
and the contact GND.
)
Pull terminal block INPUTS from its plug-in base.
)
Lay the conductors to the terminals and then check that all screws
are securely tightened.
)
Push the terminal block onto the plug-in base again.
Attention!
On no account should the external switching voltage be connected
to the housing earth of the
VideoJet 400
. The external switching
voltage must not exceed 12 V.
Note
If possible, use a bounce-free push-button as signal generator.
