F. "PRESR B" Menu
(accessible only when Dwell Mode is ON)
Screen 7
SET
PRESR B
5000
(See Screen 7.) This screen allows the operator to set the PRESR B limit
for the pump. After pressure reaches this value, the Dwell Mode feature
will be activated and the motor / electric valve will remain energized for
the specified number of seconds. The default value is 5000 psi [344 bar].
The message "Use A" will appear first. Choosing this selection will set
the PRESR B limit to the same value as PRESR A. If desired, PRESR B
can be adjusted to a different setting by pressing the Up or Down Arrow
buttons again.
CAUTION: Due to motor coast down, valve shift time,
and system oil capacitance, always set the user
adjustable relief valve 200 psi above the higher of the
two pressure values (PRESR A or PRESR B) to prevent pressure
spikes. See Section 5.4 for relief valve adjustment instructions.
IMPORTANT: When the Dwell timer is activated, the pump will
continue to build pressure to the system relief valve setting. The
relief valve setting should be adjusted to the maximum fixture
clamping pressure, to avoid over-pressurizing any components.
Note: Maximum system pressure is mechanically limited to
approximately 5,300-5,600 PSI [366-386 bar] by an internal relief
valve located within the pump element. Setting the PRESR A or
PRESR B pressure value higher than the relief valve maximum
limit will not result in higher system pressure.
G. "DWELL B" Menu
(accessible only when Dwell Mode is ON)
Screen 8
SET
DWELL B
60
(See Screen 8.) This screen allows the operator to set the DWELL B
time in seconds. After the specified DWELL B time (0 to 60 seconds)
has elapsed, the pump will de-energize the motor / electric valve.
The DWELL B value is adjusted by pressing the Up-Arrow and Down-
Arrow buttons. The message "Use A" will appear first. Choosing this
selection will set the DWELL B time to the same value as DWELL A. If
desired, DWELL B can be adjusted to a different setting by pressing the
Up or Down Arrow buttons again.
If the DWELL B time is set to zero (0) seconds, the pump will shut-off
immediately when the PRESR B limit is reached.
Save setting and step forward by pressing the Menu button. See
QRC step 3b.
