PRODUCT APPLICATION LIMITATION:
Senva products are not designed for life or safety applications. Senva products
are not intended for use in critical applications such as nuclear facilities, human
implantable device or life support. Senva is not liable, in whole or in part, for
any claims or damages arising from such uses.
CALIBRATION
1. No calibration is necessary for normal applications. Sensor
will automatically learn motor run current and adjust threshold
as needed.
2. To manually re-calibrate sensor, press and hold button for 1
second. LED will blink twice. Sensor will discontinue automati-
cally threshold adjustment.
3. To set sensor to go/no mode, press and hold button for 5
seconds. LED will blink 3 times.
INSTALLATION
1. Determine mounting location for the sensor near the
conductor to be monitored. The sensor should be located AT
LEAST 1/2” from any uninsulated conductor.
2. Sensor features a exible iris which allows the sensor to
hang on the conductor if local codes permit. A bracket is
included for screw mounting or attaching to DIN rail. For screw
mounting, drill two 3/32”pilot holes using the bracket as a
template; ensure no drill shavings are present in enclosure. At-
tach bracket with screws provided.
3. Clamp sensor around INSULATED CONDUCTOR ONLY,
600VAC MAX to be monitored.
4. Snap the sensor into the mounting bracket.
5. Wire the output of the sensor to a control panel digital
input loop not to exceed 30VAC/DC wetting voltage. Tighten
terminals to 3.5 in-lb.
Disconnect, lock out and tag out all
power supplies during installation
