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.
