ATEX AND IEC SPECIFIC CONDITIONS OF USE: ENCLOSURE
CONTAINS ALUMINUM. CARE MUST BE TAKEN TO AVOID
IGNITION HAZARD DUE TO IMPACT OR FRICTION.
PROOF PRESSURE * LIMITS LISTED ON NAMEPLATE MUST
NEVER BE EXCEEDED, EVEN BY SURGES IN THE SYSTEM.
OCCASIONAL OPERATION OF UNIT UP TO PROOF
PRESSURE IS ACCEPTABLE, E.G., START-UP AND TESTING.
CONTINUOUS OPERATION SHOULD NOT EXCEED THE
DESIGNATED OVER RANGE ** OR MAXIMUM 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 (consult factory
for re-gapping procedure).
**
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.
100 Series
Type H100 (Pressure Switch)
Type H100K (Diff erential Pressure Switch)
Refer to the final page for the Warranty.
THIS PRODUCT DOES NOT HAVE ANY FIELD
REPLACEABLE PARTS. ANY SUBSTITUTION OF
COMPONENTS SHALL INVALIDATE AGENCY
CERTIFICATION(S).
DEVICE MUST NOT BE ALTERED OR MODIFIED AFTER
SHIPMENT. CONSULT UE IF MODIFICATION IS NECESSARY.
The 100 Series pressure and diff erential pressure
switches are activated when a bellows, diaphragm or
piston sensor responds to a pressure change. This
response, at a pre-determined set point, actuates a
single snap-acting switch, converting the pressure
signal into an electrical signal. Control set point may
be varied by turning the internal adjustment hex.
(See PART II - Set Point Adjustment). Please refer to
the datasheet at www.ueonline.com for product
specifi cations. Date code format on nameplate is
"YYWW" for year and week.
Part I - Installation
• Adjustable wrench
• Screwdriver
• Hammer (for alternate wire knockouts)
Mounting
INSTALL DEVICE WHERE SHOCK, VIBRATION AND
TEMPERATURE FLUCTUATIONS ARE MINIMAL. DO NOT
INSTALL DEVICE IN AMBIENT TEMPERATURES THAT
EXCEED PUBLISHED LIMITS ON THE NAMEPLATE.
DEVICE SHOULD BE MOUNTED TO PREVENT
MOISTURE FROM ENTERING THE ENCLOSURE.
VERTICAL MOUNTING IS RECOMMENDED.
CONSIDER THE USE OF A PRESSURE SNUBBER IF
SEVERE PRESSURE SURGES ARE EXPECTED.
FOR PRESSURE MODELS, MOUNT VIA PRESSURE
CONNECTION. ALWAYS USE A WRENCH ON PRESSURE
CONNECTION HEX. DO NOT TIGHTEN BY TURNING
THE ENCLOSURE AS THIS WILL DAMAGE THE SENSOR
AND WEAKEN WELDED JOINTS.
