NAMEPLATE LABEL
Electric coil data are incorporated in the nameplate label,
which is affixed to the control enclosure cover. The label
shows all necessary information required by UL with respect
to electrical power and circuit protection requirements.
HEATER CONTROL ENCLOSURE
Figure 4 shows the interior of a typical heater control
enclosure. All components within this space work together
to provide safe operation of the heater. Although it is not
required to meet NEC requirements, Nailor recommends a
door interlocking disconnect switch
. This safety switch
must be disconnected before the enclosure can be opened.
In the absence of a disconnect switch, a
terminal block
is provided for single point power connection. A
ground
lug
ensures the proper grounding of the unit housing and
enclosure.
Line fuses and fan motor fuses
provide
overcurrent protection, and come as an option. An
airflow
switch
de-energizes the heater when it detects no airflow
across the elements.
In fan powered VAV terminal units,
auto-reset limit
switches
in line with each element provide high temperature
protection. A single
auto-reset limit switch
provides
protection for single duct terminal unit heaters. These
switches automatically cut the heater off when overheating
occurs, and turn the heater back on when the elements have
cooled down.
Manual-reset limit switches
in line with each
element provide secondary over temperature protection in
single duct terminal units.
A control
transformer
is provided whenever a 24V circuit
is required.
PE switches
(when pneumatic controls are
used), like
magnetic contactors
, are used to energize
stages of electric heat. Small heaters may often use a load
carrying PE switch as the only control component. When
control systems require frequent cycling or silent operation,
mercury contactors
are available as an option. An
SCR
control
will provide fine space temperature control and
highest reliability. For fan-powered terminal units, a
fan
relay
is provided when required or requested.
