The IntelliTRACE ITAS-EXT Series is a micro-processor based control/monitoring and power management and distribution system for heat trace applications. The ITAS-EXT Panel Series provides expanded circuit service up to 72 loops when paired with the ITAS Series Heat Trace Control Panel/Ambient Sensing. The 40 Amps per circuit capacity, the Integral Circuit Panel save significant time, installation and maintenance costs. The customizable I/O (Sensor) Mapping, the remote monitoring capability and the wireless communication option provide desirable process management flexibility options.
Soft Start Feature
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. 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 default setting of the
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 independently manage the
Soft Start Feature on each circuit.
Auto Cycle Feature
During prolonged down time periods, typically
during the summer months, it advisable to
intermittently exercise the system circuits.
This exercising of the loops is accomplished
via the Autocycle feature. On a sequential
circuit basis, the Autocycle feature periodically
monitors system performance between
1-999 hours. This provides a certain level
of predictive maintenance of the system as
Faults (Alarms) will present themselves accordingly.
Problem areas may be addressed
during non-essential operating periods. The
owner has the option to engage or disengage
the Autocycle feature at any time.
I/O (Sensor & Output) Mapping**
When factory enabled, the ITLS & ITLSC1D2
Models provide the owner with customizable
I/O Mapping. This becomes a very powerful
and desirable feature when the owner needs
added flexibility in controlling the circuit outputs
beyond the standard single sensor input.
There are two types of I/O Mapping: Sensor
Mapping and Output Mapping. Sensor Mapping
is the assignment of one or more Sensor
Inputs to one or more output circuits. Output
Mapping is the assignment of one or more
Power Outputs to one or more output circuits.
