Oil Level - Enerpac Z-Class Instruction Sheet

6.7 E Oil Level
(requires optional fl oat / temperature switch)
Display: "OIL LEVEL"
(See Screen 21) The Oil Level fault is
displayed when the oil level inside the
reservoir drops below 1.3" (34 mm)
from bottom.
6.7 F Oil Temperature
(requires optional fl oat/temperature switch)
Display: "OIL TEMP"
(See Screen 22) The Oil Temperature
fault is displayed when the temperature
of the oil inside the reservoir exceeds
175 ºF [80 °C].
6.7 G Oil Pressure
(requires optional pressure switch)
Display: "P SWITCH OPEN"
(Screen 23) The "P SWITCH OPEN"
fault is displayed when the high pressure
limit is reached and the pressure switch
opens.
Pressure Switch Notes:
• The pressure switch does not provide real time pressure data
to the LCD. For this reason, no pressure indication will be shown
on the "READY" screen unless a pressure transducer is also
installed.
• Factory installed pressure switches are typically installed in the
valve manifold "GA" port. However, if desired, the pressure switch
can be installed in the valve manifold "GB" or "GP" ports.
"GA" measures "A" port pressure.
"GB" measures "B" port pressure (if applicable).
"GP" measures pump pressure before the control valve.
6.8 LCD Warning Conditions
LCD Warnings notify the operator of abnormal operating
conditions, but allow the pump to continue operating. Warnings
will automatically clear once the abnormal condition has been
resolved.

6.8 A Low Voltage Warning
(See Screen 23) A "Low Voltage"
condition is defi ned as an operating
condition when the main power supply
is at or below 80% of nominal voltage.
While running the pump under this
condition, the "Low Voltage" signal will
fl ash on the LCD and the Low Voltage
Screen 22
hours will be counted and stored by the
OIL TEMP
microcontroller. Normal pump operation
is still permitted.
IMPORTANT: Pump operation during a Low Voltage condition
is not recommended. Motor RPM and hydraulic fl ow will be
reduced. The pump's internal circuit breaker may trip due to high
current draw, resulting in a Motor Overload fault (see section
6.7 D).
