Then, press and hold the shroud Motor
on/off button for 7 seconds. ENTRY CODE will appear on the
LCD.
Then, press and hold both the Down Arrow and Up Arrow buttons
for 7 seconds. CAL PT A will appear on the LCD.
See Table 2, “Z-Class Pressure Transducer Calibration”, located
near the end of this document. Follow the steps in the table to
perform calibration procedures.
6.6 LCD Fault Conditions
Any fault condition will shut down the pump and prevent it from
starting.
6.6 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 (~ 20 seconds),
then reconnect power.
6.6 B Power Off Fault
Display: “POWER OFF”
POWER
OFF
Screen 19
See Screen 19) The Power Off fault
occurs when the AC line power drops
to 65% or less of nominal voltage. The
pump will automatically shut-off the
valve solenoid and motor, and “Power
Off” will be displayed on the LCD.
Note: The Power Off message will also
appear for several seconds after the
pump has been disconnected from
electrical power.
6.6 C Button Fault
Display: “BUTTON FAULT”
BUTTON
FAULT
Screen 20
(See Screen 20) The Button fault occurs
when the microcontroller detects that
any button has been pressed during
the boot sequence or if the shroud
Motor on/off button has been pressed
for more than 3 seconds.
6.6 D Motor Overload Fault
Display: “MTR OVLD FAULT”
and “Motor Overload”
MTR OVLD
FAULT
Screen 21
MOTOR
OVERLOAD
(See Screen 21) The Motor Overload
fault occurs when the electrical 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 operator must clear the fault by disconnecting
and reconnecting electrical power as described in Section 6.6 A.
6.6 E Oil Temperature Fault
Display: “OIL TEMP FAULT”
OIL TEMP
FAULT
Screen 22
Note: The LCD will display this fault only if the pump is equipped
with the optional oil / level temperature switch (available only on
2.5, 5, and 10 gallon reservoir sizes).
(See Screen 22) The Oil Temperature
fault occurs when the temperature
of the oil inside the reservoir exceeds
175 ºF [80 °C].
