Power monitoring
" table
:
Power monitoring tolerances can be set/activated/deactivated in this table. Power monitoring limits in
relation to the reference power, as well as the current power are displayed. The latter is colored red
when outside its tolerance.
From this page you access the sub-menu for applying reference values.
The basic idea is to monitor the power applied to the load in order to detect if any of various parameters
drifts from its proper value (for example: excessive power consumption, etc.). A change in the power
percentage signals an abnormal physical change in the zone under control.
To monitor a control zone, a reference power value must be determined during an optimum stable
operating phase.
Once the control zone is monitored, drift is detected by comparing the applied power values with safety
tolerances set by the user.
When the monitoring system detects an anomaly it displays an alarm symbol for the faulty zone
and triggers an alarm signal at the back of the system, allowing a visual alert (alarm
indicator light) and / or deactivation of the machine cycle (IMM alarm).
The level is expressed as a percentage of the power normally applied to the zone. For example, if the
percentage of power applied to keep the zone at 180°C is 35% and the tolerance has been set at 10%,
the system will generate an alarm if the power applied to maintain the temperature exceeds 45% or falls
below 25%.

Heating element monitoring
" table
:
Heating element monitoring tolerances can be set/activated/deactivated in this table. Power monitoring
limits and the current power of the heating element are displayed. The latter is colored red when outside
its tolerance.
