The data in the Control Temp, G.F. and Current windows are displayed in color to identify their state:
• - Circuit is off
• - Within Normal range of setup parameters
• - In alarm condition
• - Control Temp only. Temperature not within setpoint + Dead Band range
• - Alarm Reset button only. A latching alarm event has occurred
The fields and displays in the Status|Circuit provide the following information:
• - Enter the Circuit number to view the status of a specific Circuit
• - In normal state, the Alarm Reset button is grayed out. If a latching alarm occurs, the Alarm Reset
blinks orange/red. The alarm cannot be reset until the fault has been cleared
• - Displays the ID tag defined in Setup/Circuit window
• - The Control Temp is the temperature the NGC-UIT3 is using for the control algorithm. If more than one RTD is
connected to a Circuit, the system displays the lowest Control Temp of all the RTDs assigned to that Circuit
• - The Setpoint is the desired maintain temperature for the circuit
• - Displays the ground-fault current for the Circuit
• - Displays the Relay device and number defined in the Setup/Circuit window
• - Displays the relay output status (on, off, or trip) of the EMR or SSR. If communication is lost to the output device, a
red COMM appears and alarms
• - Displays the Control Mode selected in Setup | Circuit window
• - Displays the heater amperage of the Circuit when the relay output is on
• - Give the input status of the CB signal. In case of a circuit breaker trip it will display in RED the text "Tripped"
The Status|RTDs window lists the RTD devices and numbers assigned to the selected Circuit, along with the last reported
temperature from each RTD and the assigned RTD Mode.
Data in this status window cannot be changed.
