setpoint entry Field
Use with On/Off, Proportional, and PASC control modes. The Setpoint is the
desired maintain temperature for the circuit.
Based on the measured control temperature, the Raychem NGC-20 and NGC-30 switches the
relay output to maintain the system at the desired set point.
Range NGC-20:
–80°C (–112 °F) to 700°C (1292 °F)
Default:
10°C (50°F)
Range NGC-30:
–73°C (–99°F) to 482°C (900°F)
Default:
10°C (50°F)
dead Band entry Field
Use with On/Off Control.
If the control temperature is above the Setpoint temperature plus Dead Band, the relay output is
turned off. If the control temperature is below the Setpoint temperature, the output is turned on.
Range NGC-30:
1°C (1°F) to 50°C (50°F)
Default:
3°C (5°F)
high temp alarm entry Field
If any RTDs assigned to a Circuit measures a temperature above this threshold, the NGC-UIT2
generates an alarm.
Range NGC-20:
–80°C (–112°F) to 700°C (1292°F)
Default:
10°C (50°F)
Range NGC-30:
–73°C (–99°F) to 482°C (900°F)
Default:
149°C (300°F)
Low temp alarm entry Field
If any RTDs assigned to a Circuit measures a temperature below this threshold, the NGC-UIT2
generates an alarm.
Range NGC-20:
–80°C (–112°F) to 700 °C (1292°F)
Default:
10°C (50°F)
Range NGC-30:
–73°C (–99°F) to 482°C (900°F)
Default:
–12°C (–10°F)
