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! Hazardous voltage can cause severe injury or death.
Turn OFF power before servicing the circuit.
WARNING! Maximum total load shall not exceed rated
capacity of the panel as listed in the equipment
ratings section.

ACCUTRACE™
Single & Dual Zone Heat Trace Control Panel
Valin’s AccuTrace™ control panel incorporates the latest technology and is packed with features designed to help
optimize your heat trace system. The easy-to-use touchscreen and non-incendive internal components allow the
panel to be used in hazardous locations (Class I, Division II, groups A, B, C, and D) while providing an easy to use
interface.
The AccuTrace™ panel utilizes PID algorithms designed to maintain temperature in the most challenging
applications. The panel has 40 amp Solid State Relay controls and 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™ has a 7”, full color, easy-to-navigate display. It can be programmed in minutes, reducing project
commissioning time and bringing the heat trace on line faster. Remain connected with protocols that include
Modbus TCP and Modbus 232/485. AccuTrace™ also oers 3 levels of password protection, to further ensure the
highest security while allowing quick access in the field, as appropriate.

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 2-1 to accomplish
proper heat dissipation.
WARNING! Installation of equipment must
be performed by qualified and experienced
personnel.
Mounting Location
Determine the mounting location based upon the
enclosure dimensions shown in the Overview Section.
If installed indoors the recommended materials include
metal surfaces, concrete, or wood. If mounting on drywall,
the construction requirements must be of at least ½”
thickness, supported by 2”x4” studs on 16” centers. If
installed outdoors, metals must be corrosion resistant
and woods must be sealed and treated for outdoor use.
Anchors must be capable of supporting at least 100lbs
each.

INSTALLATION
Conduit
All hubs and fittings shall be of Type 13, 4X to maintain
environmental ratings of enclosure. Installer shall use earthing rings
or equivalent to provide continuity of grounding between all conduit
entries. Installer shall maintain the minimum spacing between
conduit centers as noted in Figure 2-2. Conduit must be routed
through the base of the enclosure as shown in Figure 2-3 below.
The recommended area for entry is shown in Figure 2-4 below.

INSTALLATION
Hardware
The pair of brackets that come with the AccuTrace™ panel are designed to provide the necessary airflow to the
heat sink on the back of the enclosure. Ensure that airflow is not blocked or restricted in any way. Maintain at
least 12” of clearance above and below the AccuTrace™. Refer to Figure 2-5 below.
The heat sink 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.
