Alarm Inputs
The VideoJet X20 SN has four alarm inputs on the orange terminal block (see
Section 8.7 Terminal Block, page 116). The alarm inputs are used to connect to external alarm
devices such as door contacts or sensors. When configured appropriately, an alarm device
can, for example, trigger the VideoJet X20 SN to automatically establish a connection with a
remote station.
A zero potential make contact or switch can be used as the actuator.
NOTICE!
i
If possible, use a bounce-free contact system as the actuator.

Relay Outputs

other alarm units in response to an alarm signal. The relay outputs are also located on the
orange terminal block (see Section 8.7 Terminal Block, page 116).
CAUTION!

A maximum load of 30 V and 2 A may be applied to the relay contacts.
