Connecting an Accessory to the Operator Alert Contacts
This function provides you with a set of external contacts that allow the hook-up
of an alert signal of your choice.
The post accepts the following:
v
Standard dual or single banana plugs
v Leads that are terminated with spade lugs
v Stripped, bare wire leads.
The recommended voltage for the posts is 12 V dc, at a maximum current of 5
amps.
Note: There is an internal 5-amp fuse.
Voltage is not present at the binding post. You are responsible for supplying power
to run any external device. The two contacts of the binding post are connected
together with the closing of a relay contact. The relay turns on only when the
operator alert lamp is operating during an error condition. To reset or turn off the
relay, press the Check Reset switch on the Display Touch Screen window for the
affected printer.
