Installation for 4-1/2 in. (114 mm) dial Temperature MURPHYGAGE® and SWICHGAGE®
Model Series: SPLG, SPLC, SPLBP, 45TE and 45TEBP Options: -OS and -ES
SPL-92106N Revised 04-04 Section 10
(00-02-0167)
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.
GENERAL INFORMATION
WARNING
BEFORE BEGINNING INSTALLATION OF THIS MURPHY PRODUCT
Disconnect all electrical power to the machine.
Make sure the machine cannot operate during installation.
Follow all safety warnings of the machine manufacturer.
Read and follow all installation instructions.
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 contacts. 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 connected 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.
