Various symbols are used across this User Manual to caution the reader on potential safety hazards and
additional operation information. These symbols must be followed to reduce the risk of injury or damage. Below
is an index containing definitions of each symbol.
Pre-Start Up Inspection
Before installing the AccuTrace™ panel, take time to check the wiring and connections on the unit. Some
components can be aected during shipping by environmental factors, so it is important to inspect the panel
before power is applied.
SAFETY INFORMATION
WARNING - Refer to supplemental information listed next to this
symbol for details on specific hazard.
ELECTRICAL HAZARD - Hazards referring to electrical
conditions such as high voltage. Refer to specific details listed next to
symbol.
WARNING! Maximum total load shall not exceed rated capacity
of the panel as listed in the equipment ratings section.
WARNING! Hazardous voltage can cause severe injury or death.

Storage Guidelines
If this unit is not intended for operation upon receipt, follow the guidelines below to aid in preventing damage
from common environmental factors.
• Storage in a clean, environmentally controlled area is advised.
• To prevent warping during storage, unit must be placed on a solid, even surface.
• Outdoor storage of indoor units is not recommended. The packaging used for shipment of indoor units is
not appropriate for outdoor storage. Provide coverage for the unit to prevent damage from dust, dirt, and
corrosive elements. The jacketing must protect the assembly while providing sucient ventilation.
• If the storage area is aected by humidity and temperature fluctuation, utilize the anti-condensation
enclosure heater provided in the unit, or add heat from an external source to prevent condensation inside
the unit. The internal temperature must be at least 9˚F (5˚C) above ambient. If storage temperatures fall
below 32°F (0°C), utilize the enclosure heater provided, or add sucient heat from a separate source to keep
the internal temperature of the panel at least 32°F (0°C). Inspect the equipment regularly, and add additional
heat if necessary, to keep the equipment dry.
• Remove remaining packing material, paper documents, and other flammable items before operating the
enclosure heater.
Pre-Start Up Inspection
Before installing the AccuTrace™ panel, take time to check the wiring and connections on the unit. Some
components can be aected during shipping by environmental factors, so it is important to inspect the panel
before power is applied. For your safety, please review the Operation Manual prior to start up.

ACCUTRACE™
Multizone Zone Heat Trace Control Panel
The AccuTrace™ panel utilizes PID algorithms designed to maintain temperature in the most challenging
applications, for both ambient sensing and line sensing. The panel has 30-amp Solid State Relay controls and
GFEP (30mA) trip protection. a multitude of alarms, including high temp, low temp, high current, low current,
sensor failure and Ground Fault Equipment Protection, creating a package of unrivaled performance.
For extreme cold starts and long circuit lengths, the AccuTrace™ panel employs a soft start feature, reducing the
inrush current. This helps mitigate potential high current alarms that are a known problem during startups.
The AccuTrace™ multiloop has a 10”, full color, easy-to-navigate touch screen display. The control interface is
intuitive and simple to program, allowing for fast, accurate setup and commissioning. We also oer 3 levels
of password protection, to further ensure the highest security while allowing quick access in the field, as
appropriate.

ADVANCED CONFIGURATION OPTIONS
Remote Terminal Unit (RTU) Expansion Panel
Each AccuTrace™ RTU expansion panel adds an additional 4 loops of heat trace circuits to the system. They are
controlled via Modbus communications by the AccuTrace™ multiloop panel, so an additional HMI is not necessary
for the expansion unit, lowering cost.

OVERVIEW
CONTROL METHODS
The AccuTrace™ multiloop is capable of PID control, on/o control, and manual control for 48 loops locally, and
up to 224 loops remotely through the use of the RTU Expansion Panels. Each circuit may be rated up to 30A.
Auto PID Mode
A closed loop control method that will control the power output to the heat trace circuit based on a PID
algorithm. The proportional, integral, and derivative variables can be modified via the touchscreen HMI for
process optimization.
Manual Mode
An open loop control method that sets the power output to a user-specified percentage. As a safety feature,
manual mode is also the failover mode from Auto PID or On/O if the temperature sensor fails. This way, the
integrity of the process may be automatically maintained.
On/O Mode
A closed loop control method that utilizes Deadband hysteresis values to determine the power output. The
output will turno once the process temperature reaches the deadband’s high setpoint and turns on when the
process temperature reaches the deadband’s low setpoint.

INSTALLATION
1 . INSTALLATION
WARNING! AccuTrace™ utilizes Solid State Relay (SSR) power switching. To dissipate the
heat generated from the SSR’s, the heat sink located on the back of the enclosure must
be in an upright position. The panel must be mounted vertically as shown below in Figure
1-1 to accomplish proper heat dissipation.
WARNING! Installation of equipment must be performed by qualified and experienced personnel.
Installation Location
The heat sink side of the AccuTrace™ Multiloop panel is designed to provide the necessary airflow for heat
dissipation. Ensure that airflow is not blocked or restricted in any way. Refer to Figure 1-1 below. Allow 3 inches
of clearance between heat sink assemblies and surrounding equipment or walls. Allow 12 inches of clearance
above heat sink assemblies. The heat sink assemblies must be inspected every season to confirm that no debris
or objects are in contact with the heat sink. To dislodge debris, use high pressure blasts of clean air that will not
damage the fins.
