Precautions

Read these instructions before installation. Configuration may be
easier before installation.

Avoid shock hazards! Turn power off before connecting or
disconnecting wiring. All wiring must be performed by a qualified
electrician or instrumentation technician. See diagrams on other
side for wiring examples. Consult factory for assistance.

Install or remove thermometer using a wrench on the hex fitting
only. Do not attempt to turn by forcing the housing.

Do not exceed maximum allowable housing temperature.
The spring-loaded design must be used with a thermowell. The non-

spring-loaded design can be used in non-pressurized applications
or applications with no flow. Due to the hardness of 316 stainless
steel, it is recommended that a thread sealant be used to ensure
leak-free operation.

Normal Operation

The factory default configuration is °F, downscale burnout, Setpoint
1 High Alarm, Setpoint 2 Low Alarm, 1.0 degree alarm deadband,
normal acting relays, no pass code required for configure/test
alarms mode.

To turn the unit on, apply power. If so equipped, the optional display
backlighting will be on. The display backlighting will not be apparent
under bright lighting conditions.

The display segments are tested for approximately 1 second. During
the startup sequence, the alarm relays are de-energized and the
alarm status LEDs are off.

After power-up the RTD temperature and units are displayed along
with the alarm relay states as indicated by the LEDs. The display
and alarm status are updated approximately 4 times per second,

Alarm Test Mode

This mode allows testing of the alarms
regardless of the alarm trip points or the
temperature reading.

From the normal mode with temperature
being displayed, press and hold the TEST
button and then press the SEL button.

Release both buttons when the display
indicates - - - - .

- or ­If pass code protection is enabled, before

the unit enters the Alarm Test Mode, the
display initially indicates _ _ _ _ with the
left-most underscore blinking, and with
TSTPC on the lower display. Enter the user­defined pass code (3510 factory default) as
described in the Pass Code Entry section.

Note: During pass code entry the LEDs will
turn off and the unit will not respond to
changes in RTD temperature. The alarm
relays will maintain their prior states. The
unit will automatically revert to normal
operation if no buttons are operated for
approximately 15 seconds.

While in the Alarm Test Mode
with no buttons pressed,
the display will indicate the
temperature with DEG C or DEG
F slowly blinking on the lower
display.

While the TEST button is pressed
and held, both LED indicators
and alarm relays will toggle to
their opposite state. The display
will continue to indicate the
temperature.

To exit the Alarm Test Mode,
press and release the SEL
button. The display briefly
indicates - - - - and then returns
to normal operation.

Adjusting Set Points

Go to the User Configuration Mode to set up the alarm parameters
before setting up the alarm setpoints. Whenever the user
configuration mode is entered, even if no changes are made, all
alarm set points will be reset to the factory default maximum and
minimum values.

Alarm 1 factory default: HI alarm, 392.0°F trip point.
Alarm 2 factory default: LO alarm, –58.0°F trip point.

“Set Point” is defined as the temperature that will result in a change
of state only from a normal to an alarm condition.

“Trip Point” is defined as the temperature value that will result in
a change of state of alarm condition, and includes the effect of
deadband when returning from an alarm to
a normal condition.

The instructions illustrate how to change
Trip Point 1. The procedure is the same for
Trip Point 2.

From the normal mode press and release
the SEL button to display Trip Point 1. If
you want to change Trip Point 2, press SEL
again until TRIP2 is displayed.

While TRIP1 is displayed, press and hold the
TEST button and then press the SEL button.

WARRANTY/DISCLAIMER

OMEGA ENGINEERING, INC. warrants this unit to be free of defects in materials and workmanship for a period of 13 months from date of purchase.
OMEGA’s WARRANTY adds an additional one (1) month grace period to the normal one (1) year product warranty to cover handling and shipping

If the unit malfunctions, it must be returned to the factory for evaluation. OMEGA’s Customer Service Department will issue an Authorized Return (AR)
number immediately upon phone or written request. Upon examination by OMEGA, if the unit is found to be defective, it will be repaired or replaced
at no charge. OMEGA’s WARRANTY does not apply to defects resulting from any action of the purchaser, including but not limited to mishandling,
improper interfacing, operation outside of design limits, improper repair, or unauthorized modification. This WARRANTY is VOID if the unit shows
evidence of having been tampered with or shows evidence of having been damaged as a result of excessive corrosion; or current, heat, moisture or
vibration; improper specification; misapplication; misuse or other operating conditions outside of OMEGA’s control. Components which wear are not
warranted, including but not limited to contact points, fuses, and triacs.

REPRESENTATIONS OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, EXCEPT THAT OF TITLE, AND ALL IMPLIED WARRANTIES INCLUDING ANY
WARRANTY OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE HEREBY DISCLAIMED. LIMITATION OF LIABILITY: The remedies
of purchaser set forth herein are exclusive, and the total liability of OMEGA with respect to this order, whether based on contract, warranty, negligence,
indemnification, strict liability or otherwise, shall not exceed the purchase price of the component upon which liability is based. In no event shall OMEGA be
liable for consequential, incidental or special damages.

CONDITIONS: Equipment sold by OMEGA is not intended to be used, nor shall it be used: (1) as a “Basic Component” under 10 CFR 21 (NRC), used

WARRANTY / DISCLAIMER language, and, additionally, purchaser will indemnify OMEGA and hold OMEGA harmless from any liability or damage
whatsoever arising out of the use of the Product(s) in such a manner.
