Parameters (Screen 2: Activate Channel, Mode,
Controlled System Heating Rate)
Temperature Channel: Select Activated/Deactivated
Deactivated
A deactivated channel is not heated. Temperature control and monitoring for
faults do not take place. Exception: Overtemperature shutdown at a fixed
temperature value of 245°C (475°F) with standard melters or 265°C
(510°F) with high temperature melters.
Enabled
Normal state of a channel during operation. Activated channels can be
switched to display or control mode.
NOTE: Temperature channels for reservoir and grid can not be deactivated.
Deactivated
Control mode: Select Display Mode or Control Mode
Display Mode
In Display mode only the measured temperature is displayed. Temperature
control and monitoring for faults do not take place. Exception:
Overtemperature shutdown at a fixed temperature value of 245°C (475°F)
with standard melters or 265°C (510°F) with high temperature melters.
NOTE: Temperature channels for reservoir and melting plate (grid) as well
as grouped channels cannot be switched to display mode.
Control mode
The PID control algorithm is used for the selected controlled system heating
rate, e.g. Normal, in control mode.
