FCC INFORMATION TO RADAR USERS
NOTE: This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provided reasonable pro-
tection against harmful interference when the equipment is oper-
ated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interfer-
ence in which case the user will be required to correct the interfer-
ence at his own expense.
WARNING-Changes or Modifications not expressly approved by
ABM Sensor Technology Inc. could void the user’s
authority to operate the equipment.
Wiring Information
- Ground shield at one end only.
- All terminal block wiring must be rated for 250V.
- Power input wiring must be protected by a 15A double pole cir-
cuit breaker .
- Terminal is for use only with equipment which has no live parts
which are accessible .
- Terminal is for use with equipment which maintains basic insula-
tion from hazardous voltage under normal and single fault condi-
tions .
- Connection used at the remote end of external circuit .

Calibration — 4 -20 or 20 - 4 mA Output
For Radar programmable through communication is
recommended.
FULL — Calibrate 20 mA or 4mA (Set Near Target)
1. Calibration mode LED color is Green.
(for Radar Low Dielectric Materials has to be off)
2. Push button and hold until LED turns Yellow (20 mA)
or push button and hold until LED turns Red (4 mA)
3. Release button, observe LED flashes to acknowledge
the calibration.
EMPTY— Calibrate 4 mA or 20 mA (Set Far Target)
1. Calibration mode LED color is Green
(for Radar Low Dielectric Materials has to be off)
2. Push button and hold until LED turns Red (4 mA)
or push button and hold until LED turns Yellow (20 mA)
3. Release button, observe LED flashes to acknowledge
the calibration.
For Radar to turn the Low Dielectric Materials operation mode
ON and OFF (this mode is recommended for materials with
dielectric constant lower than 4 and also to eliminate multiple
reflections in tank.)
1) To turn the Low Dielectric Materials ON. Push button and hold until
LED goes OFF after the sequence of Yellow , Red and turns Off. The Low
Dielectric Material operation is On when the LED’S Green light blinks
constantly.
2) To turn the Low Dielectric Materials OFF. Push button and hold until
LED goes OFF after the sequence of Yellow , Red and
Turns OFF. The Low Dielectric Material operation is OFF when LED is
continuously Green.
3) Use communication software.
