Type-Approved OBM systems. In order to comply with the TCA requirements, the
below guidelines MUST be followed:
OPERATING MODE
User must set the scale operang mode to either Sensor Average (AVG), Esmated
Steer + Sensor Average (S-AVG), Independent (IDP), or Independent + Esmated Steer
(S-IDP). Mulple Calibraon (4CAL) Mode does not comply with TCA requirements.
DROP AXLES
PIN CODE
CALIBRATION
INSTALLATION
The vehicle must not have a drop/li axle. TCA does not approve the use of this
system on vehicles with drop/li axles of any kind.
It is required that the authorized user/installer create a PIN code for the gauge to
ensure that the vehicle operator cannot tamper with the calibraon sengs. See
page 19 for informaon on how to set the PIN code.
The gauge must be calibrated before use and then re-calibrated at least once every 6
months. Each calibraon event must be recorded in the Calibraon Log (PP-003-0065

*In 4CAL mode,
the scale can store
four sets of
calibraon data
for trailers that
have various
operang
condions.
This trailer axle group has 1
integrated li axle. Calibraon
set “1” is when the li axle is up
and set “2” is when the li axle
is down.
On some 4-axle heavy-haul
trailers, there are two fixed
axles, a li axle, and a flip axle
all on the same HCV. Many
operators use calibraon set “1”
when only two axles are down,
calibraon set “2” and “3” when
three axles are down, and
calibraon set “4” when all four
axles are down.
