The NGC-20 main screen supports different options as shown in
Figure 20 1.
Configure: to configure the selected unit.
Monitor: to monitor all process variables as currently active
on this unit. All measured sensor temperatures, control
temperature, load current, supply voltage, ground fault current
and the status of the safety limiter.
View Alarms: shows an overview of all active alarms and to
reset alarms.
