The intelliTRACE ITASC1D2 and ITLSC1D2
Series is a micro-processor based Control/
Monitoring and Power Management system
for Ambient Sensing, Line Sensing or a combination
of Line and Ambient Sensing Heat
Trace Applications and is suitable for use in
Class I, Division 2 environments.
The base panels will handle 6 - 36 loops
and may be increased up to 72 loops with
the Extension Panels. Each circuit has a 40
Amperage capacity and accepts 100 to 480
Vac service. The SCR Control may be set to
Automatic, which includes PID or On/Off control
or to Manual, which spans a 0% to 100%
The HMI is a 12” (30 cm) user friendly touch
screen computer. It displays the process variable,
temperature setpoint, alarm status, current
load, control mode, sensor failure manual
override output for any 6 loops at a time as
well as the alarm status for all other loops.
The standard enclosure is rated for NEMA 4
environments and an optional NEMA 4X 304
SS enclosure is available.
The ITASC1D2 / ITLSC1D2 Control Panel Series
provide alarms for high and low temperatures,
current load, communications, sensor
faults and ground fault leakage. There are several
output/control behavior scenarios for the
ground fault (GFEP) alarm condition. Choices
include Trip and/or Latch options in which
both, either or none may be enabled. Trip sets
the output to zero %, while Latch requires a
manual reset. Alarm events are automatically
logged and stored for easy access.
Advanced standard features include a proprietary
soft start function, off duty Auto Cycle
maintenance program and either Modbus
RTU/RS485 or Ethernet communications.
Optional features include an industry leading
I/O (Sensor & Output) Mapping** function,
remote monitoring and wireless communications.
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.
