Prologue
Thank you for buying Beamex ePG, Electric Pressure Pump and
Controller.
Beamex ePG is a portable, hand-held, battery-powered device that is used
to generate reference pressure in pressure calibration applications. With
ePG you can generate pressure between -0.85 to 20 bar / -12.4 to 300
psi. Since the device does not have a display to indicate the generated
pressure reading, it must be connected to an external pressure device
with an appropriate display, e.g. Beamex pressure calibrator or a pressure
indicator. ePG contains a lithium-ion battery pack that can be charged
using a USB Type-C charger either separately or while attached to the
device (see chapter Battery Pack).

vent mode which is indicated by the green LED blinking.
If needed, venting can be interrupted by pressing the Vent / Mode button
again. Otherwise after ca. 30 seconds venting ends and the green LED
lights up to indicate that ePG is ready to generate pressure or vacuum.
Figure 10: Coarse Adjustment Up button
Coarse Adjustment Up button is used to generate pressure in bigger steps
or at maximum speed. The button can be either clicked or pressed and
held.
When it is clicked, the ePG generates pressure in bigger steps (~ 100
to 200 mbar / 1.45 to 2.90 psi per step). When it is pressed and held,
the output pressure increases as fast as possible. Notice, that when the
generated pressure is < 2 bar / 29 psi, pumping speed is limited to prevent
possible overshots. When the pressure reaches 2 bar / 29 psi, the pump
accelerates to maximum speed.
When desired set point is getting closer, release the button ~ 0.1 to 0.2
bar / 1.45 to 2.90 psi before (the set point is reached). After releasing, the
output pressure stabilizes after a short waiting time.
Coarse Adjustment Up button can also be locked by pressing and holding
it and pressing the Fine Adjustment Up button at the same time. Locking
is indicated by the Coarse Adjustment Up button lighting up. After locking
you can lift your fingers from the buttons.
Locking can be released by pressing any of the operation (arrow)
buttons. Then the ePG holds the generated pressure and waits for further
instructions. Please notice, that if the Power or Vent / Mode button is
pressed, the device either switches itself off or vents itself.

System is not holding the set pressure.
INDICATION SOLUTION
Calibrator or external pressure
measuring device indicates that
there is a leak in the system.
Check that all pressure connections
are tight enough and they are not
leaking.
Pressure/Vacuum can not be generated.
INDICATION SOLUTION
1. Power button and the yellow LED
flashing alternatively. The green
LED is off.
1. ePG's internal temperature
is under or over the limits. All
functions to change the pressure
towards 0 bar / 0 psi are available.
Let the ePG temperature return to
normal (only green LED lights up).
2. The yellow LED is blinking and
the Power button is very bright.
2. There might be a major fault in
ePG. Power the ePG off and on
to check if the fault disappears. If
the fault indication reappears, send
your ePG to Beamex for service.
