8.0 ACCESSORY INSTALLATION

The pressure transducer, heat exchanger, pressure switch,
pendant / foot switch, valve solenoids (A) and (B) are supplied
with connectors that plug into the proper plug-ins found on the
electrical power board (Figure 11).

8.1 Pressure Transducer Installation (Requires LCD
Electric. Not compatible with pressure switch
option.)
Install pressure transducer into desired gauge port on valve
manifold. "GA" measures "A" port pressure, "GB" measures "B"
port pressure (if applicable), and "GP" measures pump pressure
before the control valve. NOTE: Factory installed pressure
transducers use port "GA".
Disconnect unit from power supply before opening electrical
box. Remove LCD half and one small hole plug from back panel.
Route wire through back panel, connect to power board (see
figure 11), and secure strain relief. Install shroud half.
The microprocessor will automatically detect the pressure
transducer and add the "Units" and "AUTOMODE" menus
during the following power up. Initial pressure transducer offset
and gain values are permanently stored in the microprocessor
memory and allow the pressure transducer to be used without
further setup. If refinement is needed to certify the LCD reading
to a master gauge, see Table 2 for calibration procedure when
using port "GA". "Contact Enerpac on procedure changes when
using port "GB" or "GP".
NOTE: Pump models with remote VE33 or VE43 electric valves,
boot sequence will also show "PRES PORT (A/B)", A = GA, B =
GB. This is the pressure port the microprocessor is
programmed for the pressure transducer to measure. The
location of the pressure transducer must match this value for
proper operation of AUTOMODE. Factory default is A. Contact
Enerpac Technical Service for procedure to move pressure
transducer setting to B port.
Variable Rate Display of Pressure
The pressure transducer is very accurate and measures
pressure real time. To aid the operator when pressure is
changing rapidly, Z-Class provides a variable rate display.
Pressure values are updated 5x per second on the display.
The microprocessor will automatically change the increment
value based on rate of pressure change, increments are 50, 100,
500, and 1000 psi. When the rate of pressure change is slow, the
display will update in 50 psi increments. When it changes
rapidly, the display will update in 1000 psi increments.
8.2 Pressure Switch
Electric. Not compatible with pressure transducer
option, electric valves, or locking manual valves)
Install pressure switch onto desired gauge port on valve
manifold. "GA" measures "A" port pressure, "GB" measures "B"
port pressure (if applicable), and "GP" measure pump pressure
before the control valve. Note Factory installed pressure
switches use port "GA".
Disconnect unit from electrical power supply before opening
electrical box. Remove LCD half and one small hole plug from
back panel. Route pressure switch wire through back panel,
connect to power board (see figure 11), and secure strain relief.
Install shroud half.
9.0 TROUBLESHOOTING (SEE TROUBLE-SHOOTING
GUIDE)
Only qualified hydraulic technicians should service the pump or
system components. A system failure may or may not be the
result of a pump malfunction. To determine the cause of the
problem, the complete system must be included in any
diagnostic procedure.
The following information is intended to be used only as an aid
in determining if a problem exists. For repair service, contact
your local Authorized Enerpac Service Center.
