OPERATION
Each of the 165 possible ID settings corresponds to a unique ID that is
associated with CPM, refill and discharge time values. For typical us-
age, only the UP/DOWN arrow keys are required to set flow, and the ID
number is provided for easy, direct return to past settings. Appendix 1
lists all possible ID settings and the default refill and discharge time
settings for each CPM. Appendix 1 also shows how the refill and dis-
charge time will change within a CPM setting as you press the UP or
DOWN keys.

Sample Collection
The PAUSE key ( ) is used to freeze the
controller action to allow the user time to collect a sample or carry out
other steps that might be difficult if the controller continued to auto-
matically cycle and cause the pump to produce water. While the cont-
roller is cycling, pressing the PAUSE key causes the controller to imm-
ediately enter the Hold state. Drive air is vented from the pump (this is
the pump refill cycle) and the pump fills and waits. Pressing the PAUSE
key a second time causes the controller to immediately enter the Sample
state. Drive air is directed to the pump causing the pump to discharge
its volume of liquid. Bladder pumps typically hold 400-500ml of liquid,
so use of the Hold and Sample states allow the full volume of the pump
to be discharged into a sample container. Pressing PAUSE once again
returns the MP10 to its normal Automatic Cycling state. During Hold
and Sample a HELD is displayed to remind you that the controller is in
a paused state. Figure 3 shows an example of the MP10 in MP mode,
but HELD in the Sample state.
Note: Pressing the Cycle key also freezes
controller cycling. However, using the Cycle key rather than the Pause
key causes the startup screen to be displayed upon restart. Use of the
Pause key is recommended for typical operation.
