5.35 Advanced Mode: Alarm Inputs

You can configure the alarm inputs of the VideoJet X20.

Alarm input

Select Active high if the alarm is to be triggered when the contact closes. Select Active low if

the alarm is to be triggered when the contact opens.

Name

You can enter a name for each alarm input, which is then displayed below the icon for the

alarm input on the LIVEPAGE if configured correctly (see Section 5.15 Advanced Mode:

LIVEPAGE Functions, page 44).

5.36 Advanced Mode: Relay

You can configure the switching behavior of the relay outputs. For each relay, you can specify

an open switch relay (normally closed contact) or a closed switch relay (normally open

contact).

You can also specify whether an output should operate as a bistable or monostable relay. In

bistable mode, the triggered state of the relay is maintained. In monostable mode, you can set

the time after which the relay will return to the idle state.

You can select different events that automatically activate an output. It is possible, for

example, to turn on a floodlight by triggering a motion alarm and then turning the light off

again when the alarm has stopped.

Idle state

Select Open if you want the relay to operate as an NO contact, or select Closed if the relay is

to operate as an NC contact.
