6.3 Fault Conditions
Any fault will shut down and prevent pump from starting.
A. Clearing a Fault Condition from the LCD
After the fault causing problem has been corrected, clear the fault
message from the LCD by disconnecting electrical power from the
pump, wait until all characters clear the LCD (~ 30 seconds), then
reconnect power.
B. Power Failure
Display: "POWER OFF"
Screen 14
POWER
(See Screen 14.) The Power Off fault is displayed when the main
power supply drops to 65% or less of nominal voltage. The pump
will automatically shut off the valves and the motor, and display
"Power Off" on the LCD. NOTE: Power Off is also displayed for
several seconds after the unit is disconnected from electrical
power.)
C. Button Fault
Display: "Button Fault"
Screen 15
BUTTON
FAULT
(See Screen 15.) The Button Fault is displayed when the
microprocessor detects any button press during the boot
sequence or if shroud on/off button is held in for more than 3
seconds.
D. Motor Overload
Display: "MTR OVLD"
Motor Overload
Screen 16
MTR OVLD
(See Screen 16.) The Motor Overload fault is displayed when the
electric current draw exceeds the pre-set limit of the pump's
internal circuit breaker. The circuit breaker will automatically
reset in about 2 to 3 minutes after the condition has been
corrected. However, before the pump can be restarted, the
OFF
MOTOR
OVERLOAD
operator must clear the fault by disconnecting and reconnecting
electrical power as described in Section 6.3A.
E. Oil Temperature (requires optional float/temperature
switch)
Display: "OIL TEMP"
Screen 17
OIL TEMP
(See Screen 17.) The Oil Temperature Fault is displayed when the
temperature of the oil inside the reservoir exceeds 175 ºF (80 °C).
F. Oil Level (requires optional level/temperature switch)
Display: "OIL LEVEL"
Screen 18
OIL LEVEL
(See Screen 18.) The Oil Level Fault is displayed when the oil level
inside the reservoir drops below 1.3" (34 mm) from bottom.
6.4 Warning Conditions
All warnings notify operator of abnormal operating condition,
however, allow pump to continue operating. Warnings will
automatically clear once issue has been resolved.
A. Low Voltage
Display: "LOW VOLT"
Low Voltage
Screen 19
LOW VOLT
LOW
VOLTAGE
(See Screen 19.) A "Low Voltage" condition is defined as an
operating condition with the main power supply is at or below
80% of nominal voltage. While running the pump under this
condition, the "Low Voltage" signal will flash on the LCD and the
Low Voltage hours will be counted and stored on the control
board. Normal pump operation is still provided.
CAUTION: For optimized pump performance it is
recommended NOT to run the pump at Low Voltage
condition.
