Temperature Parameters (contd.)
Overtemperatur
e shutdown =
Setpoint temperature + (Overtemperature fault + 10°C)*
Setpoint temperature + (Overtemperature fault + 20°F)*
The overtemperature shutdown is calculated and therefore cannot be
changed.
Example (Standard Melter)
Setpoint temperature = 170°C (338°F),
Overtemperature fault = 60°C (108°F)
This results in
Fault Overtemperature at 230°C (446°F)
Overtemperature shutdown at 240°C (466°F).
During operation the operator increases the setpoint to 190°C (374°F);
leaving the value Overtemperature fault delta unchanged. Mathematically, an
overtemperature fault indication would then occur at 250°C (482°F).
Shutdown occurs at a fixed value of 245°C (475°F).
