E) Rel-
The relative lower tolerance limit can be selected here, relative to the set-
point. If the tolerance is fallen short of, the “Minimum Temperature Toler-
ance Fallen Sort Of” alarm is triggered.
F) Max
Maximum permissible temperature can be selected here.
If the specified temperature is exceeded, the “Upper Temperature Limit
Value” alarm is triggered and the heaters are switched off.
G) CCS Button (optional)
This button is used to switch the Capability Control System on and off.

Setpoints can be entered and actual values can be displayed in this window.
In addition to this, tolerances and limits for manipulated variables can be
specified here for the heaters.
A) Designations of the individual heaters
B) Setpoint
Entry field for temperature setpoints.

These fields are identical to those
in the main window.
C) Actual Value
Temperature display for the heaters.
1
These fields are identical to those
in the main window.
D) Ymax (setpoint limiting)
Maximum heating power as a percentage: If set to less than 100%, heat-
ing power is pulsed in order to limit power.
E) Y (current setpoint)
Current manipulated variable
F) Rel+
The relative upper tolerance limit can be selected here, relative to the set-
point. If the tolerance is exceeded, the “Maximum Temperature Tolerance
Exceeded” alarm is triggered.
G) Rel-
The relative lower tolerance limit can be selected here, relative to the set-
point. If the tolerance is fallen short of, the “Minimum Temperature Toler-
ance Fallen Sort Of” alarm is triggered.
H) Max
Maximum permissible temperature can be selected here.
If the specified temperature is exceeded, the “Upper Temperature Limit
Value” alarm is triggered and the heaters are switched off.

J) Temperature sensor
Temperature after Pyrolysis regulation.
K) Monitor
Monitoring/Protection of the heating element.
L) Pyrolysis On/Off
It indicates if Pyrolysis runs.
Note!
If the set values (default-values) are not preset over 210°C in at
least 2 Peak-zones, the pyrolysis heatings are not controlled. If the
set values are over 210°C in at least 2 Peak-zones, the pyrolysis
heatings are controlled automatically and the valve air or nitrogen
is open (depending on the switch position).
If the heating is switched off, the delay time is expired which lets
the air or the nitrogen flow further 5 min. in order that the pyrolysis is cooled
down.
