The External Power Option may be used in
lieuoftheinternalbatterypack. TheExternal
PowerOption(model No. EPO-120)consists of
aACto DC convertor andintrinsically safe
barrier to convert 120 VAC power to 28 VDC to

internalbatterypack.
The Solar Power Option would be used in lieu
oftheinternalbattery pack. The Solar Power
Option (model #SPO-12) consists of a 5 watt

pack.
3. Theory of Operation:
The DynaPak 3010RNM Sampler is a liquid
samplingsystemwhichusesthepneumatically
operated,positive displacement DynaPak
3000HPpump,theZ-65/6.1timer/controller,
thePIM-100interfacemodule,theYZfilter/
regulatorandalowpowersolenoidvalveto
obtain liquid samples. The 3010RNM has
two modes of operation:
A. Time-based sampling: in this mode of
operation,the3010RNMextractsaliquid
samplefromthe pipeline at regular time
intervals.Thevolumeofthesampleissetbythe
operatorusingthevolumeadjustmentfeatureof
theDP-3000HPpump.TheZ-65/6.1controller
operatesasarecyclingtimer, periodically
energizingalowpowersolenoidvalve.
Energizingthesolenoidvalveallowsexternally
provided actuation gas to stroke the DP-3000
HPpump. Therate at which thisoccurs is a
functionofoperatorinput. Two10position
switchesareusedtosettheofftimeinterval.
Thisallows a stroketime intervalof 1- 99
minutes. Thenumberoftimesthesolenoid
outputisactivated is recorded bythe onboard
LCD stroke indicator.
B. Proportional-to-flow sampling: in this
modeofoperation,theZ-65/6.1counter
