Remove the housing cover.
Place the instrument on an insulated surface or support
so the sensor does not touch a conductive surface.
Apply 12 to 28VDC, and observe the LED. (See on page 2)
NOTE: When the LED is on, it indicates the output is in the normal state 16-20mA.
Turn the sensitivity adjustment clockwise (up to 25 turns) to increase sensitivity until
the LED goes out.
NOTE: Do not turn the sensitivity adjustment past 25 turns! Damage to the unit could result.
Turn the sensitivity adjustment counterclockwise to decrease sensitivity until the
LED illuminates.

Turn the sensitivity adjustment slowly clockwise until LED goes off, then
counterclockwise until LED goes on to check the null position to verify that the bridge is
balanced. It is desirable to closely bracket the position where the LED came on.
Turn the sensitivity adjustment one turn counterclockwise from the null position. Next,
slowly move a hand toward the probe to touch it. The LED should stay on until the
probe is touched. If it goes out when the hand is near, turn the sensitivity control
counterclockwise so the LED stays on until the hand touches the probe. Usually,
1-2 turns will locate the new null point.
When practical, use a small container of actual process material to calibrate the control.
If the actual process vessel is metal, use a metal container (coffee can, etc.) and ground
it to the instrument housing. If the actual process vessel is an insulator, such as,
fiberglass, use a plastic container.
Immerse the sensor in the process material; the LED should turn off. If not, rotate the
sensitivity adjustment clockwise until the LED goes off.
To detect an interface, such as oil/water or foam/liquid, the lighter material must be in
contact with the sensor, then tuned out. Then adjust the sensitivity to detect the heavier
process material. (See and )

Standard conguration is a 3/4” NPT(M) pipe nipple that threads into a 3/4” NPT(F) vessel
nozzle or half coupling. Allow a 4” turn radius (See and ). Sometimes open tanks,
vats, sumps or basins require a locally-made bracket mount similar to that shown in.
(See ).
Optional conguration is a raised face or flat face ANSI flange. See Form 1100 for
selection. (See

and )
Orientation. The control can be mounted in any position. Sensitivity is optimized when the
greatest surface area of the sensor is parallel to the process level. (See

Electrical Connections
When the process is adhesive, i.e. it tends to coat the sensor, it may be desirable to mount
it on a 45° angle to reduce product build-up and to increase its effective surface area. (See
and )
Placement and orientation of the sensor in a vessel is frequently determined by available
nozzles. The sensor should be away from fill points to avoid false trips. The insulator
bushing on the sensor should protrude a minimum of 1” from the inner wall of the vessel.
The sensor must not touch any metal, nor should conductive product build-up be allowed
to bridge between the sensor and a grounded metal tank wall.
This product must be installed with an explosion proof breather vent per
Agency requirements and the National Electric Code-Article 501, Section F,
paragraph 3.
Electrical power must be disconnected from explosion proof/intrinsically
safe models before the cover is removed. Failure to do so could result in
severe personal injury or substantial property damage.
Remove the housing cover. Ensure that all wiring conforms to all applicable local and
national electrical codes and install unit(s) according to relevant national and local
safety codes.
Connect the positive loop power wire to the terminal marked “+”.
Connect the negative loop power wire to the terminal marked “-”.
Replace the cover.
Apply power.
Post-Installation Calibration
Units in Hazardous Locations — Prior to calibration, make certain that the
work area is declassied before removing the explosion proof cover to
calibrate the unit. Failure to do so could result in severe personal injury
and/or substantial property damage.
Turn the set-point adjustment to the full clockwise position. The LED should be off
(in Hi Level Fail-safe mode).
Turn the adjustment slowly counter-clockwise until the LED just changes state (on).
Raise the material level until it is above the sensing element. The LED should be off.
Turn the adjustment slowly counter-clockwise until the LED illuminates. Then turn the
adjustment 1/2 turn clockwise (LED off) to complete the calibration.

Instructions for EMC
651K9
When subjected to an RF Interference, the
651K9 will maintain the +1% accuracy in
all frequency ranges. In order to achieve
the stated accuracy for the 651K9, a
shielded cable, cable gland, shield bead
and the probe should be mounted in a
metallic vessel. SOR recommends using
a shielded cable made of PVC
Insulation around a tinned copper braid
shield (Olflex CY cable or equivalent).
Refer to illustrations for installation of
shield bead onto the probe wire.
