Senix ULTRA-30 Series User manual

ULTRA-30 ultrasonic dis-
tance sensors provide an
output between 0 and 10 volts
DC that is proportional to the
distance of a measured target.
The voltage output range can be
calibrated to span the distance
between any two distance "end-
points" in the sensor's range.
The slope can either increase
or decrease with distance. Both
endpoints are push-button
adjustable. It includes a sensitive
transducer and electronics in a
small threaded, rugged, anod-
ized aluminum enclosure that is
easily mounted. Typical applica-
tions measure roll diameters,
and object sizes and height.
• Designed for indoor or dry
environment applications
• Standard 0-10 VDC output
has adjustable distances and
polarity
• Long range, short deadband
• High sensitivity for weak or
non-woven targets
• Simple pushbutton “teach”
setup of many features, and
calibration using actual targets
• Rear LED Status indicator
quickly identifies proper and
improper target conditions
• CE compliant for use in EU
• Output response filter for
stability with unstable targets
• Security “Lock” prevents
accidental mis-adjustment
• All in one small package!
• Simple 3-wire interface–power,
ground and voltage output
• Threaded aluminum
housing quickly bolts into a
round mounting hole
• Permanently attached 2-meter
cable
• Simple push-button TEACH
setup - no potentiometers!
• Rear pushbutton is used with
rear indicator to accomplish all
TEACH features
• Rear indicator displays target
status conditions including too
close, no target and target out
of calibrated range.
• Detects both hard and soft
objects
• Stable outputs and output filter
options
• No light or laser beam required
• Works in the dark
• Works with optically reflective,
transparent or opaque materials
• Unaffected by target color

Rear Status Indicator
This LED has four functions:
(1) ON continuously when a
stable target is within the adjust-
ed 0-10 VDC span, (2) flashes
slowly for targets out of span but
in sensor's range capability, (3)
flashes quickly when no target
is detected or target is closer
than the minimum range and (4)
flashes slowly during TEACH
setup.
Push-button Switch
Used to set the TEACH features
listed in table. To TEACH, count
the status indicator flashes while
switch is pressed and held.

Flashes Sensor Feature Selected
4 Set the 0 VDC distance endpoint (anywhere in range, using a target)
5 Set the 10 VDC distance endpoint (anywhere in range, using a target)
6 Set response time = SLOW (step change approx. 10-90% in 4 seconds)
7 Set response time = FAST (updates every 50 mSec.)
10 Unlock/lock sensor for adjustment. Relocks automatically after 15 min-
utes or power is recycled.
12 ULTRA-30-VA: Set LONG range and all factory defaults
ULTRA-30L-VA: Set factory defaults with 8-in. (203 mm) minimum range
13 ULTRA-30-VA: Set SHORT range and all factory defaults
ULTRA-30L-VA: Set factory defaults with 6.5-in. (165 mm) min range
Note: Adjust a feature by holding TEACH button pressed until the LED flashes the number of times in
the "TEACH Flashes" column, then release it. The sensor must first be unlocked using 10 flashes. It
any TEACH feature is attempted before Unlocking, the rear indicator will display 3 successive short-
long flashes then the sensor resumes operation and all reatures remain unchanged.
This product is not recommended for applications with hazardous or explosive materials, or as a primary device for personal safety.
