Definitions for each of the Temp Setup Input Cells:
Name:
Customize the Name of this individual circuit or loop
Temp STPT:
Process Temperature Set Point (degrees F or C)
HI STPT:
High Temperature Alarm Limit (degrees F or C)
LO STPT:
Low Temperature Alarm Limit (degrees F or C)
Auto/Manual:
Select Auto if you wish the Output behavior to be a function of a PID Algorithm or ON/OFF
Control (See Tuning Tab for selection)
Select Manual if you wish the Output to be driven by a pre-determined Output Percentage.
Enter the desired % output.
Disable Output:
Select this check box if you wish to turn off or disable this circuit.
Apply Globally:
This allows the user to copy all of the settings or Circuit Parameters from Circuit #1 to all other
available circuits.
Apply Settings Globally
The ITLS/ITAS has a feature which allows the user to apply settings from a single circuit to all of the remaining
circuit within the system. Within Circuit #1 on the Load Setup Menu (See Figure 6), complete the input of the pa-
rameters and select the “Apply Glob” button to mirror these settings across all circuits.
Soft Start Feature
These control panels are ideal for controlling heat trace
cable. Certain heating cables exhibit inherent current
inrush in colder temperatures. This inrush can cause
nuisance breaker tripping. To limit inrush current on
the overall system, a proprietary soft start algorithm is
applied during system start-up. This will ONLY occur
while the operation mode is set to AUTO.
The soft start program will increment output % by
1% every 1 second until the desired temperature is
reached or the output % achieves 100%. After the soft
start program completes its cycle, the control mode of
the system will either be PID or ON/OFF Control Mode,
depending what was selected by the user.
The soft start program will not function if the control
mode is set to Manual.
The default setting of the proprietary soft start feature
for each circuit is “enabled”. However, the soft start
feature may be disabled if so desired by the owner. The
owner has the option to manage the soft start feature
on each circuit individually.
See Figure 5.
