SOR GI169 Instruction manual

1/12
This instruction provides information for mounting, electrical
connection, process connection, and calibration of SOR®
Temperature Switches.
The SOR Temperature Switch consists of a pressure switch
with a sealed temperature sensing bulb attached directly to the
pressure port. (An optional remote temperature sensing bulb may
be connected to the pressure port with an armor-clad capillary.) The
temperature sensing system is pressure filled with a volatile fluid.
Process temperature changes cause proportional vapor pressure
changes in the temperature sensing bulb that act on the diaphragm/
piston assembly to actuate and deactuate a snap-action electrical
switching element at discrete process temperatures. The
instrument’s
behavior is
determined by vapor pressure
(105 range model fill media is inert gas).
NOTE: If you suspect that a product
is defective, contact the factory
or the SOR Representative
in your area for a return
authorization number (RMA).
This product should only be
installed by trained and
competent personnel.

Installation
Direct-Mount Probe
The temperature sensing probe is rigidly attached to the instrument’s body/housing.
nCarefully insert the sensing probe into the process through a suitable fitting or
thermowell. The standard process connection is 1/2-inch NPT(M).
oEnsure that ample clearance exists before rotating the instrument housing to make
threaded connection.
pTighten the probe hex fitting with 1-1/8-inch open-end wrench for a leak free fit.
NOTE: A locally customized mounting bracket may be used if more support is desired.
Housings L, S, TA, V1, V2, LC, SC, BA, B3, B4, B5 and B6 are not recommended for direct
mount where vibration is expected. These housings should be securely mounted to a at
surface (bulkhead or panel rack) or pipe stanchion.
Remote-Mount Probe — Capillary
nSecure the housing-mounting pad to bulkhead, panel rack or pipe stanchion with
suitable 1/4-inch (6.35 mm) bolts.
oMounting by electrical conduit connection is NOT recommended.
p Suggested mounting orientation is electrical conduit connection at 3 or 9 o’clock
and sensing body at 6 o’clock. However, the device is not position sensitive and
may be mounted in any position. If a breather drain is installed, it must be
oriented at 6 o’clock (pointing down) so condensation will drain. It must be kept
clear of paint and foreign matter.
q Carefully insert the sensing probe into the process through a suitable fitting or
thermowell. Adjust the desired insertion length. Tighten the probe hex fitting with
a 7/8” open-end wrench. Tighten 9/16” hex nut to fingertight. Then hold the 7/8”
fitting with a wrench and tighten the 9/16” hex nut an additional 1-1/4 turns from
finger tight. Avoid sharp bends in capillary.
When mounting to an irregular or uneven surface, install rubber washers on
bolts between the housing and mounting surface (except for high vibration
applications) to prevent deformation of housing, which could change relative
positions of internal parts and affect calibration or render device inoperative.

3/12
Process Connection
The temperature sensing probe is 300 series stainless steel. If the process is
compatible, it may be directly inserted into the process without the use of a thermowell.
Best results are obtained when the probe is completely immersed in the process.
A thermowell increases response time (lag). A thermowell filled with thermal transfer
media reduces lag.
Safety Integrity Level (SIL) Installation Requirements
The SOR pressure switches have been evaluated as Type-A safety related hardware.
To meet the necessary installation requirements for the SIL system, the following
information must be utilized:
Proof Test Interval shall be one year.
Units may only be installed for use in Low Demand Mode.
Products have a HFT (Hardware Fault Tolerance) of 0, and were evaluated in a
1oo1 (one out of one) configuration. Form 1538 (03.12) ©2012 SOR Inc.

Electrical Connection
When making electrical connections, use care to apply minimal strain to the electrical
switching element. Refer to wiring schematic below for terminal and wire codes.
Ensure that wiring conforms to all applicable local and national electrical codes and
install unit(s) according to relevant national and local safety codes.
The Switching Element Assembly has been precisely positioned in the
housing at the factory for optimum performance. Any inadvertent movement
or replacement in the eld will degrade performance and could render the
device inoperative, unless factory authorized procedures are followed.

The permanently attached cables are to be suitably terminated and protected
from impact and UV light.
To minimize the risk of electrostatic discharge, clean only with a damp cloth.
The switch capsule has an expected life cycle of 1x105, therefore end user shall
ensure that the switch capsule does not exceed the stated life cycle.
Flameproof joints are not intended to be repaired
Special Conditions for Safe Use for ATEX/IECEx Certied
Mini-Hermet Temperature Switches only
Calibration
 Disconnect electrical power to the temperature switch.
NOTE: It is not necessary to disconnect electrical power with the Big Hermet series or models
in B3, B4, B5 and B6 housings provided that only the cover fastened with four captive screws
over Set Point adjustment is removed.
 Remove the housing cover (or weathertight cap).
Units in Hazardous Locations – Prior to calibration, make sure that the work
area is declassied before removing the explosion proof cover to calibrate
the unit. Failure to do so could result in severe personal injury or
substantial property damage.
For instruments with 3/4-inch hex set point adjustment:
Use 3/4-inch open-end wrench to turn hex adjusting nut clockwise (in) to increase
set point, and counterclockwise (out) to decrease set point.
Approximate set point can be obtained by sighting across top of adjusting nut to
calibration scale on the housing floor.
If precise set point calibration is required, it will be necessary to use a regulated
thermal bath and suitable continuity tester. Consult factory.
For instruments with dead band adjustment:
Use the fixed dead band procedure (above) to calibrate the desired decreasing
temperature set point. The increasing temperature set point can then be adjusted by
turning the white thumbwheel on the electrical switching element. Setting Ayields the
smallest possible dead band. Setting Fyields the widest possible dead band. Settings
above Emay degrade repeatability.
Do not unthread the adjusting screw more than two threads below the ush
point of housing as calibration could be adversely affected.
For instruments with 1/8” hex Allen wrench set point adjustment under weathertight cap:
Use 1/8” hex Allen wrench to turn adjusting screw to achieve desired set point.
Turn the adjusting screw clockwise (in) to increase set point and counterclockwise
(out) to decrease set point.
A calibration scale is not installed, so external measurement of the process
temperature is necessary. Consult the factory.
