Turning The Mp50 On; Opening Display - QED MP50 Instruction Manual

Operation
Operation
Turning the MP50 Display On - The MP50 is powered on automatically by opening the lid.
The MP50 displays an opening screen for 5 seconds, after which it displays the default Micro-
Purge screen. At this point the MP50 is in MicroPurge mode (MP) but not cycling the pump.
This initial state allows the user to adjust time and throttle settings before the pump starts to
operate. Pressing the Cycle key begins pump cycling. Times and modes may be adjusted
while the pump is cycling or before. Pressing the Cycle key a second time will stop pump
cycling.
Note: all user-entered time settings are lost when the MP50 is turned off. Also, the MP50
automatically powers down when the lid is closed, so make sure the MP50 is stored with its
lid closed.
Opening Display - The opening display is shown for 5 seconds and displays the controller
name, the version number and the battery voltage, as shown in Figure 1. Figure 1 shows that
the battery is GOOD, that the battery voltage is 4.20 volts and that the software version in the
cont-roller is 1.0. Battery voltage must be greater than 3.6 volts for the unit to operate. If the
unit fails to cycle replace the 3-AA batteries with fresh cells. The opening screen is displayed
for 5 seconds, if you wish to by pass the opening screen, hitting any key, such as the CPM key
will bring you to the default MP display.
