To prevent the accidental use of OPS function, the OPS reverts back to its default
setting of zero each time the inflator is powered down.
WARNING
When using the OPS function, the sum pressure must not exceed the tire
manufacturer's maximum inflation pressure.
Nitrogen Purge Setting (N2P)
"N2P" represents the number of "purge" cycles, inflation and deflation of the tires, the
inflator will perform. To set the number of purge cycles, or N2P, press the
"SET/MODE" button. The display will flash “OPS” and the OPS set value alternately.
Press the "SET/MODE" or (i) button again and the display will flash “N2P” and the
N2P set value alternately. To change the N2P, press the "+" or "-" buttons. Save your
selection by pressing the "FILL/PURGE" or ( ) button. The N2P setting can be
changed again when required. N2P is preset to '"2" and can be set per above from "0"
to"9" purges.
Deflation Value Setting (DPS)
"DPS" represents the deflation value, or the value to which the tires will deflate, during
the first deflation cycle when the unit is in the "N2P" mode. DPS is preset, and defaults
upon power up, to 5 psi but is adjustable from 4 psi to 50% of the target pressure. All
subsequent deflation cycles, from the second deflation on, if more than one N2P
cycles are selected, will deflate the tires to 25% of the target pressure. This "multiple
deflation" value is not adjustable.
For example, DPS is preset to 5 psi, if it is not changed, and the unit is set to N2P
"1," upon activation the tire will deflate to 5 psi and re-inflate to the target pressure. If 2
N2P cycles are chosen, and DPS remains at 5, the tire will deflate to 5 psi, re-inflate to
the target pressure, deflate to 25% of the target pressure and finally re-inflate to the
target pressure. If DPS "6" is chosen, the tire will deflate to 6 psi on the initial deflation,
and deflate to 25% of the target pressure on any subsequent deflation cycles.
Hence, if a final target pressure of 32, an N2P setting of "2," and a DPS of 5 are
chosen, the tire will deflate to 5 psi, re-inflate to 32 psi, deflate to 8 psi (25% of 32 psi)
and finally re-inflate to 32 psi.
To set DPS, press the "SET/MODE" or (i) button. The display will flash “OPS” and the
OPS set value alternately. Press the "SET/MODE" or (i) button again and the display
will flash “N2P” and the N2P set value alternately. Press the "SET/MODE" or (i)
