The Main Screen
The Main screen displays the summarized information for each circuit. Point out:
•
Full text circuit ID for easy identification of the circuit.
•
Measured pipe temperature so that you know what the present status is of the pipe
temperature.
o
At this point, touch the UIT on one of the circuits to bring up the Status
screen for that circuit.
o
Mention that if you want to know any additional information on that
particular circuit, touch it and the applicable Status screen will appear with
additional information.
o
Then touch the Main tab to return to the Main screen
•
Setpoint is listed so that you can compare the measured temperature to the
setpoint. Because no-one knows what the target temperature is from memory.
•
For circuits with On/Off control mode, the deadband setting is displayed.
•
Then the line current and ground-fault currents are displayed
•
The status of the heat tracing circuit is also shown – is it on or off at that moment.
•
Finally, the status of the 3 internal alarm relays is displayed. If an alarm is active on
any one of those relays, then the displayed square will be red. All green means
everything is good.
