 - When the heating cable is OFF, the temperature measurements will be transmitted from the SES, SPC and 700-TT
transmitters to the PLI module/NGC-30 controller based on the configured PLI Update Interval time. The NGC-30 system turns the
heater on in the time intervals defined in the field PLI Update Interval and reads the temperature measurements. Based on these
temperature measurements and the Setpoint, NGC-30 Control System determines whether to leave the heater On or turn it Off.
If the Update Interval time is set to 10 minutes, the NGC-30 control system turns ON the heater every 10 minutes.
On time intervals when no additional heat is required is as follows:
For 700-TT Transmitter ….. 5 seconds
For SES Transmitter ……..Highest SES Address Number for that circuit / 2 + 5 = in seconds
Range: 1-255 Minutes
Default: 10 Minutes

After entering a start time, the Power Cycle test feature turns on the heat tracing for a one-minute period each day starting at the
indicated time. If the heater system is damaged during a season when the system would normally be turned off, the daily Power Cycle
test can help detect the problem within 24 hours. This is particularly helpful in warm months when heat tracing may not be energized.
Range: vAny time selected from the 24-hour clock (00:00–23:59, where 00:00 is off)

The default interval is 24 hours. The example in the window above schedules a one-minute test every morning at 6:00 a.m. Other
entries are possible, but multiples of 24 hours are recommended to preserve the predictable start-time. For instance, 48 hours will run
the test at 6:00 a.m. every other day. 168 hours will run the test once a week starting with the first occurrence of 8:01 a.m. after the
set-up procedure and once a week thereafter. To run the test twice a day, enter 12 hours etc.
Range: v1–1000 hours
Default: 24 hours

This entry is used to create a heater inspection maintenance schedule. Enter the number of hours the heater can be energized
before inspection and testing is due. The NGC-UIT3 tracks the accumulated “on” time for each heater circuit and generates an alarm
message and advises that heater maintenance is due.
Range: 1–1,000,000
Default: 100,000
