industrial heat tracing solutions
These are the general settings for the Raychem NGC-30:
Range: –73°C (–99°F) to 482°C (900°F)
Default: 482°C (900°F)
For Raychem NGC-20:
Range: –80°C (–112°F) to 700°C (1292°F)
Default: 700°C (1292°F)
Low Limit Cut-out entry Field - nGC-20 only
Low Limit Cut-Out feature is triggered depending on Control and RTD Modes of the NGC-20. Table
3.3 indicates which RTD Modes will initiate a Low Limit Cut-Out for each Control Mode. If these
RTDs are assigned to a Circuit and measure a temperature above the Low Limit Cut-Out threshold,
the NGC-UIT2 generates an alarm and the relay output is turned off. If the Low Limit temperature
is above this threshold plus the variable Deadband, the output is turned on.
Limit Cut-out enable/disable toggle Buttons
Enables or disables the high limit cut-out capability. When enabled, the NGC-UIT2 alarms and the
output relay turns OFF if any RTDs exceed the cut-out value. If the high limit cut-out is disabled,
the relay output will continue to function normally without the high temperature cut-out feature.

3.3.8 setuP | eLeCtriCaL WindoW

This window configures ground fault alarm and trip values for the Circuit. (This feature is only
supported when used with CRM/CRMS or Raychem NGC-20 controller boards. This feature is not
supported with RMC controller output modules. Ground fault alarm is a latching alarm and must
be reset.) These alarms are latching alarms and must be reset.

Ground-Fault alarm entry Field
Set the Ground-Fault Alarm threshold to the desired level. The ground-fault alarm may not be
disabled.
