SPLC and SPLFC
SWICHGAGE
®
instruments have high
and low limit contacts to monitor, alarm or shutdown. The SPLC
has a flanged case. SPLFC has a flush mount case intended for
installation within a panel. A method to override the low limit
contact for startup is provided on most models (see Operation
Test Instructions on page 3).
45TE and 45TEF Series
are versions of the SPL Series
with 2-snap acting SPDT switches instead of the pointer type con-
tacts. The 45TE Series does not include low contact lockout.
SPLBP and 45TEBP
models are designed to start and stop
electric motor driven equipment. The pilot duty contacts are con-
nected to a latching control relay for automatic ON/OFF control,
either directly or through a motor starter.
Options -OS and -ES
The -OS (oil sealed case) and the -ES (environment sealed case)
options for corrosive environment feature flush mount case design
to be installed within a panel.
Precautions
■
Do NOT exceed rated temperature range.
■
Use shock mounts as necessary to protect from vibration.
■
Cutting or sharp bending the capillary will cause permanent
damage to the SWICHGAGE
®
and will void the warranty.
■
Excess capillary should be carefully coiled and secured
away from damage.
■
Do not route capillary along exhaust manifold.
■
Avoid routing capillary at level higher than gage mounting.
Please read the following instructions before installing.
A visual inspection is recommended before mounting.
General Information and these installation instructions are intended for all 4-1/2 in. (114 mm) dial temperature models.
