Run Screen Alarms
Alarm Indication Comments
Left/Right/Intensifier
Overstroke
Abnormally high stroke rate caused by
an external or internal leak. Shutdown
will occur if condition persists.
Overstroke warnings, pending
shutdowns and shutdowns are issued
as left, right or intensifier. An
intensifier warning or shutdown
indicates the intensifier is shifting too
fast in both directions. If the machine
is running near full capacity it is
possible an intensifier shutdown is
actually caused by a left or right fault.
This can be diagnosed further by
reducing the operating pressure and
monitoring all alarm occurrences on
the Alarms Screen.
If the machine is equipped with a
pressure transducer, another level of
overstroke protection is obtained by
shutting down at the warning level if
the pressure is less than 3,000 psi (207
bar).
Low Battery Battery is low. After the alarm
occurs, the battery will last for
approximately seven days.
Replace with backup/replacement
battery.
Low Booster
Pressure
Booster pump output pressure is
inadequate for proper machine
operation, less than 60 psi (4 bar).
Shutdown is pending.
Seven seconds after the machine is
started, the booster pump output
pressure switch is monitored. If the
switch opens, a warning is issued. If
the condition persists, shutdown will
occur after 30 seconds.
Low Inlet Water
Pressure
Cutting supply water pressure is
inadequate to permit proper machine
operation, less than 30 psi (2 bar).
If the inlet cutting watering pressure
switch is not closed the machine will
not start and a warning is issued. If
the switch opens after the machine is
started a warning is issued. If the
condition persists shutdown occurs
after five consecutive seconds.
Reset Inlet Water Inlet water solenoid valve must be
reset.
RESET will flash and can be
reset by pressing the
STOP button
