OR NON-HAZARDOUS LOCATIONS ONLY. ENCLOSURE
TYPE 4X, IP66. AMBIENT TEMPERATURE RANGE -50°C
(-58°F) TO 71°C (160°F).
ATEX AND IEC SPECIFIC CONDITIONS OF USE:
ENCLOSURE CONTAINS ALUMINUM. CARE MUST BE
TAKEN TO AVOID IGNITION HAZARD DUE TO IMPACT
OR FRICTION.
THIS PRODUCT DOES NOT HAVE ANY FIELD REPLACEABLE
PARTS. ANY SUBSTITUTION OF COMPONENTS SHALL
INVALIDATE AGENCY CERTIFICATION(S), AND IMPAIR
SUITABILITY FOR CLASS I, DIV. 2 LOCATION.
The 117 series pressure and diff erential pressure
switch utilizes a bellows or diaphragm sensor to
detect a pressure change.
The response, at a pre-determined set point,
actuates a SPDT or DPDT snap-acting switch,
converting the pressure signal into an electrical
signal. Control set point may be varied by turning
the internal adjustment hex (see Adjustment-Part II).
PROOF PRESSURE* LIMITS STATED IN THE
LITERATURE AND ON NAMEPLATES MUST NEVER
BE EXCEEDED, EVEN BY SURGES IN THE SYSTEM.
OCCASIONAL OPERATION OF UNIT UP TO PROOF
PRESSURE IS ACCEPTABLE (E.G. START-UP, TESTING).
EXCESSIVE CYCLING AT MAXIMUM PRESSURE
LIMITS COULD REDUCE SENSOR LIFE. CONTINUOUS
OPERATION SHOULD NOT EXCEED THE DESIGNATED
OVER RANGE** OR WORKING PRESSURE RANGE ***.
*
Proof Pressure - the maximum pressure to which a pressure sensor
may be occasionally subjected, which causes no permanent damage
(e.g., start-up, testing). The unit may require re-gapping.
**
Over Range Pressure - the maximum pressure to which a pressure
sensor may be continuously subjected without causing damage and
maintaining set point repeatability.
***
Working Pressure Range - the pressure range in which two oppos-
ing sensors can be safely operated and still maintain set point provided
the diff erence in pressure between the low and high sides does not
exceed the designated adjustable range.
DEVICE MUST NOT BE ALTERED OR MODIFIED AFTER
SHIPMENT. CONSULT UE IF DEVICE MODIFICATION IS
NECESSARY.
