Operation - An ultrasonic/electromagnetic pulse is transmitted from the
ABM sensor . The pulse travels to the surface being monitored and is
reflected off this surface back to the sensor . The time of flight is divided
by 2 and converted to an output signal directly proportional to the
material level .

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 protection against harmful interference when
the equipment is operated 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 interference
in which case the user will be required to correct the inter­ference 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 circuit 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
insulation from hazardous voltage under normal and sin­gle fault conditions .

- Connection used at the remote end of external circuit .
