Introduction/Quick Start

Introduction / Quick start

Introduction:

The MP10H Micro Purge Basics Controller is used to operate QED Well Wizard™ bladder sampling pumps to purge and sample ground water. The MP10H has specific design features to make MicroPurge ™ sampling easier. These features include:

MicroPurge Mode Operation

Simple Increase / Decrease keys allow you to easily set the flow rate you need for each well.

ID Time Set Mode Operation

Quickly recalls pre-determined settings for each well by specifying a 3-digit ID.

Level Delay Interface

The controller plugs into the optional MP30 MicroPurge Drawdown / Water Level Meter to provide direct feedback of well drawdown and to pause pump operation until the level recovers.

The optional MP30 MicroPurge Drawdown / Water Level Meter plugs into the MP10H to provide water level feedback. The MP30 uses a standard conductivity probe to detect the ground water surface and a marked tape allowing the user to measure the depth. When the meter is set in MicroPurge mode, the probe is lowered a specific distance below the static water level and fixed in this position. During well sampling if the water level drops below the user-set probe position, the MP10H is paused which prevents further drawdown by the pump. Once the level recovers the MP10H begins pump operation again, starting in the pump refill cycle. Use of the MP10H with the MP30 is detailed later in this manual.

Insert Batteries:

Remove the battery cover on the top of the MP10. Insert 3, AA alkaline batteries into the battery holder and carefully replace the holder in the carrier. Replace the battery cover and tighten the 4 screws. Batteries should last for about 6-8 weeks of typical full-time field use. If the MP10H will be stored longer than about 3 months, the alkaline batteries should be removed to prevent leakage.

Bladder Pump Operation in Low-Submergence

Bladder Pump Operation in Low-Submergence Applications

Pump submergence is defined as the height of the static water column above the top of the pump. In wells in which this water column height is 5 feet or less, the pump is considered to be in a low-submergence application.

QED sampling bladder pumps fill by hydrostatic pressure. As the inside of the pump's bladder fills with water, the bladder expands. This filling and expanding of the bladder is referred to as the "refill" half of the pump cycle. When air pressure is applied to the outside of the bladder, the bladder is squeezed, forcing the water up the discharge tubing. This is referred to as the

"discharge" half of the pump cycle. In low-submergence applications, there is less water pressure available to expand the bladder during the refill.

This can result in a smaller volume of water being pumped with each pump cycle because the bladder may not fully expand.

As a result of the lower volume per cycle, more time will be required to bring the water to the surface. An easy way to verify that the pump is working, prior to the water reaching the surface, is to submerge the pump's discharge tubing in a beaker of water. Each time the pump goes into discharge, air in the discharge tubing, which is displaced as the water level in the tubing rises, can be seen as air bubbles coming from the end of the tubing. To optimize the pumping rate, the refill time should be set long enough to achieve the maximum volume of air bubbles on each pump cycle, and the discharge time should be set long enough to ensure that the air has stopped bubbling out of the tube before the pump controller switches back into refill.

In low submergence wells,

it is critical that the air pressure driving the pump not be more than 10-15psi higher than the minimum re-quirement of 0.5 psi per foot of pump depth.

Higher pressures than this can cause the bladder to be squeezed too tightly during discharge, a condition which can prevent the bladder from expanding during refill. To avoid this condition in deeper wells, it is suggested that the air pressure applied to the pump be gradually increased as the water level in the pump's discharge tubing rises. It is recommended that the air pressure be set at 15 psi initially, and slowly increased in increments of 10 psi as needed until the water reaches the surface. Submerging the end of the discharge tubing under water as described above will verify whether the air pressure is set high enough.

Operation

Operation

Turning the MP10H Display On -

The MP10H is powered on automatically by opening the lid.

The MP10H displays an opening screen for 5 seconds, after which it displays the default Micro-

Purge screen. At this point the MP10H 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 MP10 is turned off. Also, the MP10H automatically powers down when the lid is closed, so make sure the MP10H 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 controller 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.

Manual Mode For Pumps Located At Pump Depths Over 250 Feet

For deep wells manual mode (MN on the display), is useful for manually setting refill and discharge times on the controller as in traditional controllers (like previous model QED pump controllers). An example of the MP10H in Manual Mode is (shown in Figure 2). Manual Mode is also used when there are other conditions where one of the 165 possible preset times of ID and MP modes will not match your needs. MN mode is entered when the MODE key is pressed twice from the default MP mode.As shown in Figure 2, the display indicates MN mode in the lower left corner and CPM and ID are not displayed.

In Manual Mode the CPM and UP, DOWN keys function differentlythan MP mode. The CPM key becomes a key used to select the digits of the refill and discharge time settings found at the rightmost positions on the display. The UP and DOWN keys are used to adjust the digit value up or down. By selecting and adjusting digits up and down a user can quickly set any time from 00.1 seconds to 999.9 seconds. Sampling in Manual Mode is the same as explained, above, for MP mode.

The MP10H does not attempt to translate a user set time into a corresponding ID or CPM.

Also, any settings you have entered in MP or ID modes are lost once you press the MODE key to enter MN mode.

Note:

changes in time settings that are entered while the controller is cycling are reflected on the next cycle change (so a long refill time of 15 seconds will time out before a new refill time becomes valid).

Operation

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 automatically cycle and cause the pump to produce water. While the controller is cycling, pressing the PAUSE key causes the controller to immediately 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 400-500 ml 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 MP10H 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 MP10H in MP mode, but

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.

Operation

Flow Throttle Use

The flow throttle is used during sampling to regulate the pressure applied to the pump.

Turning the throttle clockwise increases the pressure and counterclockwise decreases the pressure. The pressure gauge shows the approximate pressure applied to the pump. This allows easy adjustment of the throttle giving pressures that will produce gentle, nonturbulent flow (normally 5-10 psi higher than the minimum requirement of 0.5 psi per foot of pump depth). For traditional, high volume purging pressure may be increased with the throttle to maximize pump flow during well purging.

11

Operation

MicroPurge Mode for pumps located at depths less than 250 ft.

Most MP10H users will leave the controller in the default MicroPurge (MP) mode. See Figure 4 for an example of the MP10H in MP mode.MP mode lets you to use the UP and DOWN keys to directly increase and decrease pump flow rates.The MP10H has a broad range of other CPM settings to ensure the availability of a time setting that will match your specific conditions. MP mode also displays an ID, with a value of 1 to 165 that matches the flow settings (CPM and refill and discharge times you have set). This ID should be noted alongside the well identification

(QED provides custom weatherproof ID badges for purchasers of our MP series of well caps) for quick setting of the optimal controller settings on the next visit by using the MP10H in ID mode.

Using CPM

The MP10H introduces a simpler way to control bladder pump flow rate and achieve the low-flow method used by experts. Up/down arrow keys are used to adjust pump flow even at very low rates, with excellent control and repeatability.

With previous bladder pump controllers, a leading low-flow technique called for selecting the number of pump cycles per minute, then adjusting the bladder pump discharge and refill times to achieve the desired volume per cycle. These adjustments were interrelated, complex, and varied by operator. The new MicroPurge Mode (MP) of the MP10H builds in a "cycles per minute", or CPM, method of flow control.

12

Operation

With this method, the number of complete pump cycles per minute is fixed, within a range of 1 to 6; 4 CPM is the default value which appears at startup. Each time the up/down arrow keys are pressed, the pump refill and discharge times are both automatically adjusted to maintain the selected CPM value. Each adjustment increases or decreases the volume pumped per cycle, and the per-minute flow rate is the volume per cycle X the CPM value.

For example, with a 4 CPM setting, 60 ml volume per cycle equates to 4 X 60 = 240 ml/min flow rate. A single press of the Flow up-arrow key could change the volume per cycle to 80 ml, for example, resulting in a new, increased flow rate of 4 X 80 = 320 ml/min. And the MP10H assigns a unique identification value to each setting, the ID value, which can be directly set during later sampling events.

"MP" displayed in the lower left corner of the display indicates MicroPurge mode.The default CPM setting of 4 cycles per minute is a good starting point for wells with depths from 25-100ft. Micro-

Purge mode starts at a time setting of 10 seconds refill and 5 seconds discharge, close to optimal for many wells. This startup settings corresponds to a 4 cycles per minute setting (CPM4) and an

ID setting of 103.

Using the CPM key will change the CPM setting on the controller. The range of CPM settings is

CPM1 through CPM6. CPM changes like this each time you hit the CPM key: 4 5 6 1 2 3 4 5, etc. The UP and DOWN keys change the flow rate directly, by altering the refill and discharge times within a CPM setting.

Note:

changes in settings that are entered while the controller is cycling are reflected on the next cycle change (so a long refill time of 15 seconds will time out before a new refill time becomes valid).

Each of the 165 possible ID settings corresponds to a unique ID that is associated with CPM, refill and discharge time values. For typical usage, 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 discharge 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 automatically cycle and cause the pump to produce water. While the controller is cycling, pressing the PAUSE key causes the controller to immediately 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-

500 ml 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 MP10H 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 MP10H 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.

14

Operation

Flow Throttle Use

The flow throttle is used during sampling to regulate the pressure applied to the pump.

Turning the throttle clockwise increases the pressure and counterclockwise decreases the pressure. The pressure gauge shows the approximate pressure applied to the pump.This allows easy adjustment of the throttle giving pressures that will produce gentle, non-turbulent flow (normally 5-10 psi higher than the minimum requirement of 0.5 psi per foot of pump depth). For traditional, high volume purging pressure may be increased with the throttle to maximize pump flow during well purging.

Use with the MP30 Automatic Drawdown Control

The MP10H may optionally be used with the MP30 MicroPurgeDrawdown / Water Level Meter.

See Figure 5 for an example of the MP10H in MP mode with the controller in a level paused state enacted by an MP30 meter.

Operation

The MP10H and MP30 are connected with a cable (see Figures 6 and 7). The MP30 is switched into mode and the water level probe is lowered to the desired maximum drawdown level. Limiting the maximum drawdown depth limits the differential head driving flow into the well and the velocity of the water flowing into the well from the surrounding formation important in MicroPurge sampling. The MP10H and MP30 work together to automatically adjust the pump operation so as to maintain drawdown at the set level. When the water level drops below the probe, the MP30 sends a signal to the MP10H to pause pumping. Both the

MP10H and the MP30 give visual signals (and the MP30 emits an audio signal) that pump operation has stopped because of too much drawdown. Once the level recovers, the MP30 signals the MP10H to resume pump operation. The MP10H resumes by starting in the refill leg of the pump cycle. "DRAWDOWN CONTROL"

The normal operating mode for using the MP30 with the MP10H is:

1.

Use the MP30 in standard WLM mode to determine the static water level in the well

2.

Decide what the maximum drawdown for that well is during sampling

3.

Lower the probe to the maximum drawdown level

4.

Switch the MP30 into Drawdown Control mode

5.

Begin pumping with the MP10H

6.

Observe the interactions between the two devices, if the MP30 is frequently pausing the

MP10H, it may be appropriate to slow the flow down (using the DOWN key in MP mode)

to better match pump flow to well recharge.

When switched into MODE, the MP30 has a flashing red light and an optional (can be switched off by the user) audio alarm to indicate when the probe is in the dry state. A submerged probe in all modes is indicated by a solid green light. When the MP10H is paused by the MP30 the

MP10H display indicates this as shown in Figure 5."DRAWDOWN CONTROL"

17

Operation

If the MP30 is signaling the MP10H too frequently, the operator can slow down the pump flow rate by using the DOWN key (effectively increasing the pump refill time period). MP30 probe position may also be varied to provide a buffer zone for your draw-down limit and gauge rate of pumping effect on water level in the well.

If the selected maximum drawdown level is being reached even with the lowest desirable pump flow rate more drawdown may be required to attain equilibration, or a passive sampling approach may be required. In passive sampling, used where well recovery is extremely slow, samples are taken after just a few pump strokes sufficient to purge the pump and tubing volumes.

Additional information on the MP30 is given in the MP30 O&M manual

ID Mode

Figure 8 shows an example of the MP10H in ID time set mode. Once you've used the

MP10H in MP mode and found proper settings for your wells, subsequent sampling events are speeded along by using the controller in ID mode. Once the controller is turned on, a single press of the MODE key places the controller in ID time set mode (the default initial mode is MP mode). This mode allows the user to enter a 3-digit ID, which then is translated into the correct flow settings (CPM and refill / discharge time settings) for that well.

CPM.Appendix 1 also shows how the refill and discharge time will change within a CPM setting as you press the UP or DOWN keys. As you change IDs you will see the CPM change and the refill and discharge time setting change.

Note:

changes in time settings that are entered while the controller is cycling are reflected on the next cycle change (so a long refill time of 15 seconds will time out before a new refill time becomes valid).

MP10 Battery

The MP10H features sophisticated power-supply circuitry that optimizes battery life. A fresh set of AA batteries will provide more than 100 hours of controller operation at normal operating temperatures. As ambient temperatures drop below 15-20˚ F (-9˚ C to -6˚ C), the ability of the alkaline batteries to deliver energy is affected. Continuous operation may be difficult in extremely cold conditions. Once the batteries and MP10H warm, additional cycle capacity will be regained from a set of batteries.

Replace alkaline batteries by removing the 4 thumbscrews located on the battery cover and inserting 3 fresh

cells

. The MP10H battery holder includes space for

3 spare AA cells

so you should never be without power in the field. Properly dispose of the spent alkaline cells.

Note:

If you are storing the MP10H for more than 3 months, remove the AA batteries to prevent leakage. The MP10H power supply is automatically shut off by closing the lid. Make sure the lid is closed during storage.
