In Vortex and Vortex Panel the Display Module is mounted on the enclosure door. In Vortex Rack, the
Display Module is mounted on a 19"rack panel. For Vortex DIN there is no Display Module and
monitoring can be done using the RS485 port on the Node Controller Module (see section 4.2)
The Display Module displays the status of each channel. If any alarm or fault condition is detected, the
relevant LED lights up on the Display Module. Depending on the configuration of the system, the
internal sounder on the Node Controller Module emits a sound, and anyassigned relays operate.
Details of the displays module features can be found below.The type of input monitored on each
channel may be indicated on the front of the Display Module by a label above the LEDs for that
channel.
