E. Oil Temperature (requires optional float/temperature
switch)
Display: "OIL TEMP"
Screen 5
OIL TEMP
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 6
OIL LEVEL
The Oil Level Fault is displayed when the oil level inside the
reservoir drops below 1.3" (34 mm) from bottom.

6.3 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 7
LOW VOLT
LOW
VOLTAGE
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.
6.4 LCD Menus
(Also refer to Table 1, Quick Reference Chart (QRC) located after
Section 9.0)
A. Normal Operation
Screen 8
(See Screen 8.) LCD screen on a Z-class pump. CB has booted
successfully (OK); the pressure reading is 0 psi. Enter into the
menus by pressing the Menu button. See QRC step #1.
B. "Set Pres" Menu (Firmware 5.5 and earlier)
Screen 9
SET PRES
SET
(See Screen 9.) This screen allows the operator to set the trigger
pressure value the pump will either shift the valve (VE33 and VE43
electric valve) or turn the motor off. The specific operation of the
motor / electric valve is factory set by pump model. See the "Pump-
Model-Matrix", Page 16, Table 3 for details by pump model number.
Changes in increments of 50 psi (3.5 bar) by pressing either Down
(Up) Arrow button or keep either button pressed for speed setting.
Maximum pressure value 10,500 psi. NOTE: The hidden calibration
menu for the digital gauge is accessed from this menu. Save setting
and step forward by pressing the Menu button. See QRC step #2.
Caution: Due to motor coast down, valve shift time, and
system oil capacitance, always set the user adjustable
relief valve 200 psi above the "SET PRES" or "HI
PRESS" value to prevent pressure spikes.
C. "Units" Menu
Screen 10
SET
(See Screen 10.) This screen allows the operator to set the unit
of pressure-measurement by pressing the Down (Up) Arrow
buttons. PSI, BAR, Mpa are the options with PSI being the
default. Save setting and step forward by pressing the Menu
button. See QRC step #3.
