The Z-65/6.1 counter periodically energizes a
low power solenoid valve. As in the time based
sampling mode of operation, this allows
actuation gas to stroke the DP-3000 HP pump.
The rate at which this occurs is a function of
operator input as well as the turbine flow meter
or other device that inputs pulses per volume
metered. The two 10 position switches on the
Z-65/6.1 are used to set the number of input
pulses the counter will count before activating
the solenoid output. The number of times the
solenoid output is activated is recorded by the
onboard LCD stroke indicator. Sample volume
is again controlled using the DP-3000 HP
volume adjustment knob.
In both modes of operation, the Z-65/6.1 timer/
counter operates using a replaceable internal
battery pack. The battery pack condition is
monitored by way of two indicator LEDs. Under
normal conditions, the green indicator LED will
illuminate when the solenoid output is actuated.
When the battery pack needs replacement, the
red LED will illuminate when the solenoid output
is activated. If the battery pack is good, the
green LED will illuminate when the solenoid is
activated.
The External Power Option may be used in
lieu of the internal battery pack. The External
Power Option (model No. EPO-120) consists of
a AC to DC convertor and intrinsically safe
barrier to convert 120 VAC power to 28 VDC to
operate the controller without the use of the
internal battery pack.
The Solar Power Option would be used in lieu
of the internal battery pack. The Solar Power
Option (model #SPO-12) consists of a 5 watt
solar panel with RM-12 charger regulator
module and internal 12V, 5 Amp hour battery
pack.
3. Theory of Operation:
The DynaPak 3010RNM Sampler is a liquid
sampling system which uses the pneumatically
operated, positive displacement DynaPak
3000 HP pump, the Z-65/6.1 timer/controller,
the PIM-100 interface module, the YZ filter/
regulator and a low power solenoid valve to
obtain liquid samples. The 3010RNM has
two modes of operation:
A. Time-based sampling: in this mode of
operation, the 3010RNM extracts a liquid
sample from the pipeline at regular time
intervals. The volume of the sample is set by the
operator using the volume adjustment feature of
the DP-3000 HP pump. The Z-65/6.1 controller
operates as a recycling timer, periodically
energizing a low power solenoid valve.
Energizing the solenoid valve allows externally
provided actuation gas to stroke the DP-3000
HP pump. The rate at which this occurs is a
function of operator input. Two 10 position
switches are used to set the off time interval.
This allows a stroke time interval of 1 - 99
minutes. The number of times the solenoid
output is activated is recorded by the onboard
LCD stroke indicator.
B. Proportional-to-flow sampling: in this
mode of operation, the Z-65/6.1 counter
operates as a dividing counter. The PIM-100
Pulse Input Module is a low power device
designed to interface between a DynaPak Z-65
controller and a magnetic pickup input. The
PIM-100 provides fixed width logic level output
pulses used to drive the count input of a Z-65
controller at a rate determined by a user
configurable divisor. The switch settable
divisor, ranging from 1 to 524,287, divides the
input pulses from a turbine flow meter by the
cumulative number represented by the “ON”
divisor switches. An input adjustment
potentiometer is provided to allow adjusting the
input sensitivity. Power is derived from the
Z-65 battery pack.
