graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

2.1
Milltronics TASS overview
The TASS trailing arm speed sensor is a compact, low-profile, wheel-driven return belt
speed sensor. The TASS has a sensor wheel and trailing arm assembly that rides along the
return belt. The sensor wheel rotates on a shaft fixed to the trailing arm. The internal
proximity switch detects rotation of the wheel, generating a signal proportional to belt speed.
The output signal is transmitted via cable connection to the integrator to determine the rate
of conveyed material.

The TASS speed sensor attaches to the static beam of the associated belt scale, or to a
structural cross member via a pivot and bracket assembly.
Do not allow the slope of the TASS arm to exceed 45° below the belt stringer line.
①TASS
②Milltronics belt scale
Note
Ensure that the wheel is in contact with the belt at all times.

3.1
Mounting location
Locate the TASS near the scale assembly to simplify wiring. The wheel should ride on the
return belt, either just before or just after a return belt idler.

Connection

Note
All wiring must be done in conjunction with approved conduit, boxes, and fittings and to
procedures in accordance with all governing regulations.
Ensure that there is sufficient slack in the cabling to allow the TASS arm to pivot freely so the
wheel rides on the belt. Restriction of the arm can cause slippage or excessive contact
between the belt and the wheel.
