External Alarm Contact
The INS-806 Industrial Switch has one Alarm Contact
located on the green Power Block Contact on the top
panel. For detailed instructions on how to connect the
Alarm Contact power wires to the two middle contacts of
the 6-contact terminal block connector, see the
Connecting DC Power inputs in the section above (it is
the same procedure).
You can connect the Fault circuit to any warning light
which the user’s factory or industry already has located in
the control room or factory floor. When a fault occurs, the
Switch will send a signal through the Alarm contact, to
activate the external alarm or siren. The Alarm Contact
has two terminals that form a Fault circuit for connecting
to an alarm system.
An alarm will be signaled in the following situations:
1.
Ports 1 ~8: link fail (ex: cable disconnected,
device break down .....)
2.
PWR/RPS: Power failure
a.
Power cord is disconnected, power
supply malfunction, etc.
b. Input power is out of the range listed in
the spec (9 ~ 48V)
