Adjust Carrier’s
Pressure Relief
SETTING FLOW & PRESSURE
Now adjust the oil flow on the carrier, so the flow meter reading equals:
TC51L/FC: 8-12 USgpm (30-45 l/min) TC51H/FC: 12-18 gpm (44-68 l/min)
TC71: 13-17 USgpm (49-63 l/min) TC71FC: 13-22 gpm (49-83 l/min)
TC80: 20-26 USgpm (75-97 l/min)
TC91S: 18-24 USgpm (68-91 l/min)
TC151S: 25-31 USgpm (95-117 l/min) TC151SH: 35-43 gpm (132-163 l/min)
TC301: 35-43 USgpm (132-163 l/min) TC301H: 50-61 gpm (189-231 l/min)
To ensure the carrier's pressure relief valve does not activate while the compactor
is working, the pressure relief must be set at least 350 psi above the maximum
working pressure of the compactor.Continue to load the circuit pressure by adjust-
ing the flow meter. Eventually the carrier's relief valve will activate and the oil
flow will drop to zero. The pressure at which the oil goes over relief will be dis-
played on the flow meter. If this pressure setting is at least 350 psi or greater than
the maximum working pressure of the compactor, your machine is ready. If not,
you need to adjust the carrier's pressure relief setting.
TC51 2200 + 350 psi = 2550 psi (176 + 24 = 200 bar) relief
TC71 2000 + 350 psi = 2350 psi (136 + 24 = 160 bar) relief
TC80 2000 + 350 psi = 2350 psi (136 + 24 = 160 bar) relief
TC91S 2000 + 350 psi = 2350 psi (136 + 24 = 160 bar) relief
TC151S: 2000 + 350 psi = 2350 psi (136 + 24 = 160 bar) relief
TC151SH: 1600 + 350 psi = 1950 psi (109 + 24 = 133 bar) relief
TC301: 2000 + 350 psi = 2350 psi (136 + 24 = 160 bar) relief
TC301H: 1600 + 350 psi = 1950 psi (109 + 24 = 133 bar) relief
If more than one attachment with different flow requirements is to be connected
to this carrier, you will need to measure the flow and note the adjustments of
each. Mark these two locations directly on the flow control valve.
Record the oil flow and relief pressure settings when filling out the BTI
Compactor Installation Notice form.
If you are unable to obtain the proper flow when installing or adjusting the
hydraulic circuit, contact your BTI dealer for technical support.
