About ePG - 14 Battery Pack The battery provides a long operation time and can be quickly charged. You can also charge a spare battery separately, and replace in the field when needed Figure 4: Battery Pack locked When the slot is in a vertical position the Battery Pack is locked. - Page 15 When the temperature is under or over the limits (other than 0 °C to 45 °C / 32 °F to 113 °F) the Battery Pack cannot be charged. Additionally, if the internal temperature is over 60 °C / 140 °F, the ePG stops working automatically as a precaution until the temperature is within the limits again.

Connect one of the remaining open ends to the calibrator's/pressure measuring device's input connection. Connect the last open end to DUT's* input connector. -
Page 17: User Interface And Functionality
You can operate the ePG by pressing the buttons on the device. Figure 7: Buttons on the device Figure 8: Power button The ePG is powered-on by pressing the Power button. This is indicated by Power button lighting up. When powered-on, the device goes automatically into the vent mode. This is indicated by green LED blinking. - Page 18 Operating instructions - 18 Figure 9: Vent/Mode button Vent/Mode button is used to vent the ePG or change the mode from pressure to vacuum and vice versa. When pressed, the ePG goes into the vent mode which is indicated by the green LED blinking.
- Page 19 The button can be either clicked or pressed and held. When it is clicked, the ePG decreases pressure in bigger steps (~ 100 to 200 mbar / 1.45 to 2.90 psi per step). When it is pressed and held, the output...

Coarse Adjustment Down button lighting up. After locking you can lift your fingers off the buttons. Locking can be released by pressing any of the the arrow buttons. The ePG then holds the generated pressure and waits for further instructions. Please notice, that if the Power or Vent/Mode button is pressed to release the lock, the device either switches itself off or vents itself. -
Page 21: Enabling Communication Between An Mc6 Family Calibrator And The
The MC6 family calibrator does not automatically recognize your ePG. You need to configure the controller communication to pair the devices. Note: If you have more than one ePG, you can assign each ePG to a separate Controller Presets channel (maximum 4). -
Page 22: Working With An Mc6 Family Calibrator And The Epg
Examples: • With P6C, the ePG provides the lower setpoint limit (-0.85 bar / -12.4 psi) and the pressure module provides the upper limit (6 bar / 87 psi) •... -
Page 23: Settings/Controller Presets: Shut Off Vs. Continuous
Shut off Shut off means that once the setpoint is reached, pressure adjustment stops. The ePG will not try to adjust the pressure even in case of an overshoot and the hysteresis will be preserved. Continuous Continuous means that pressure adjustment continues even after the setpoint is reached. -
Page 24: Venting And Zeroing
There are two different ways to vent the ePG with MC6 family calibrator. The ePG vents when you enter value 0 in the Gauge pressure mode. If no other setpoint is given, Vent leaves the valves open for 1 minute. This gives the user some time to zero the reference pressure module. - Page 25 Operating instructions - 25 Figure 18: Vent button - Documenting Calibrator mode Figure 19: Vent menu - Documenting Calibrator mode...

Page 31: Opening An Instrument While The Epg Is Not Connected
Operating instructions - 31 Opening an instrument while the ePG is not connected If you open an instrument, where controller communication is needed and the controller is not available, the calibrator will prompt you about a missing controller. You are still able to access and edit the instrument and when you connect the pressure controller, calibration can start. -
Page 32: Working With The Calibration Management Software
Calibration Management Software configuration (CMX or LOGiCAL). Working with CMX Requirements There is no need to upgrade the CMX version in order to start using the ePG. The only requirement is that your MC6 family calibrator is able to communicate with your CMX version. - Page 33 Operating instructions - 33 If you want the calibrator to automatically accept the calibration points, make sure you have the following configurations in the procedure window: • Acceptance set to automatic; • Max Deviation sets a range around the setpoint (in % of span). When the Input is within the set range, the calibration point can be automatically accepted, even though the exact setpoint has not been reached;...

By activating the star ( ) next to the selection, you can set the selected row to be the preferred method. This calibration method will be selected by default when assigning the calibration tasks from LOGiCAL.
- Page 37 Operating instructions - 37 • Calibration Point Delay: defines the time (in seconds) the calibrator waits after the Input is stable before the readings are accepted; • Max Deviation: sets a range around the setpoint (in % of span). When the Input is within the set range, the calibration point can be automatically accepted, even though the exact setpoint has not been reached.

Page 55: Maintenance
Note: Please notice that the ePG must be in the Pressure mode during the dryout procedure. If any parts of the ePG require cleaning, use a cloth damped with a water-based or alcohol-based solvent. Alternatively, use low concentration of hydrogen peroxide or mild solution of mild soap water. -
Page 56: Regular Inspections
(8006160, 5 pcs). Check the condition of the Mesh Filter at least every 3 months. A Mesh Filter prevents impurities from getting into the ePG during venting. The Mesh Filter might require cleaning or changing from time to time. The Mesh Filter can be found under the output fitting. -
Page 57: Method A (Removing Condensation)
Maintenance - 57 Choose the correct method depending on the serial number of the device: • Method A (removing condensation) - valid for the devices with a serial number 20240054 and higher; • Method B (removing condensation) - valid for all devices with firmware version 2.20 or later, however method A is a preferred and reliable method of removing condensation for newer devices. - Page 58 Maintenance - 58 When the ePG is powered-on, press the Coarse Adjustment Up button and hold it for 1-2 minutes. During this time the possible condensation is pumped out from the Pressure Block. Warning: Be extra careful not to put your fingers between the Piston Assembly when the ePG is powered-on and it starts generating pressure (when the motor is running).

Page 71: Firmware Update Instructions
To update the firmware version follow the instructions below. Note: It is not recommended to use the ePG update application with a Windows version older than Windows 10. If Beamex ePG Electric Pressure Pump and Controller firmware is updated from a PC for the first time, correct Windows driver needs to be installed: Connect the USB cable between the ePG and PC. - Page 72 This will stop firmware update mode by doing a forced power down of the ePG. Alternatively, disconnect the ePG's battery to power down the ePG. III. After powering down, the ePG will no longer be in firmware update mode and will start normally after pressing Power button again.
