display. The stroke rate is displayed as a percentage
of the fastest rate. If you attempt to go beyond these
limits, the display will show three dashes indicating you
have reached a limit.
To run the V300 system in manual mode, simply turn
the Mode Switch to "MANUAL" using a screwdriver.
Note: In manual mode, the motor will not start until the
user presses the "RUN" button. This allows the user to
adjust the stroke rate prior to starting the pump. The
last stroke rate to be selected before turning off the
power will be the stroke rate stored for the next power
up.

Analog Input Modes
General Note:
While configured for a remote inter-
face, the actual percentage of the Stroke Rate
Maximum is displayed on the LCD for easy monitoring.
a) 0-5 Volt Mode:
Use this mode to remotely control
the stroke rate with a voltage source of 0 to 5 VDC.
This voltage level interface utilizes the "ANALOG
INPUT" connector on the control module to connect to
the user's voltage source. (see figure 2)
Standard RG58 or other coaxial cable should be uti-
lized for inducted noise immunity. The 0-5 volt inter-
face requires approximately 2 mA of drive current at 5
volts thus making it compatible with most analog volt-
age interface modules. The stroke rate is displayed as
a percentage of the fastest rate. The stroke rate is lim-
ited to a minimum of 5.0% and a maximum of 100.0%.
If the control voltage is less then the minimum of 5.0%
the display will alternate three dashes and the control
value, indicating you are under the limit.
To run the V300 system in 0-5 V mode, simply turn the
Mode Switch to "0-5 V" using a screwdriver (see Fig 1).
0-5 Volt input specifications:
Isolated input:
limited to ± 30 VDC from
earth ground.
Input voltage range
0-5 VCD
Input current at 5 volts
2 mA
Maximum Rate (100.0%) 4.5 V
Minimum Rate (5.0%)
225 mVDC
Interface Linearity
1.5%
Accuracy
1%
Caution:
If power is applied to the control unit
while in 0-5 V mode, the motor will start automatically if
the input voltage is 225 mV or above. The "STOP" and
"RUN" buttons will stop and start the pump while in the
0-5 VDC mode however the up down arrows are not
functional in this mode.
b) 0-10 Volt Mode:
Use this mode to remotely control the stroke rate with
a voltage input source of 0 to 10 VDC. This voltage
level interface utilizes the "ANALOG INPUT" connector
on the control module to connect to the user's voltage
source. Standard RG58 or other coaxial cable should
be utilized for inducted noise immunity. (See Figure 2
for cable connections)
The 0-10 VDC interface requires approximately 1 mA
of drive current at 10 VDC thus making it compatible
with most analog voltage interface modules. The
stroke rate is displayed as a percentage of the fastest
rate. The stroke rate is limited to a minimum of 5.0%
and a maximum of 100.0%. If the control voltage is
less then the minimum of 5.0% the display will alternate
three dashes and the control value, indicating you are
under the limit.
To run the V300 system in 0-10 V Mode, simply turn the
Mode Switch to "0-10 V" using a screwdriver. (See
Figure 1)
0-10 Volt input specifications
Isolated input:
limited to ± 30 VDC from
earth ground.
Input voltage range:
0-10 VDC
Input current at 10 volts: 1 mA
Maximum Rate (100.0%): 9.5 VDC
Minimum Rate (5.0%):
450 mVDC
Interface Linearity:
1.5%
Accuracy:
1%
Caution:
If power is applied to the control unit
while in 0-10 V Mode, the motor will start automatically
if the input voltage is 450 mV or above. The "STOP"
and "RUN" buttons will stop and start the pump while in
the 0-10 Volt mode however the up down arrows are
not functional in this mode.
c) 4-20 mA Mode:
Use this mode to remotely control
the stroke rate with a current source of 4 to 20 mA DC.
This current level interface utilizes the "ANALOG
INPUT" connector on the control module to connect to
the user's current loop controller.
Standard RG58 or other coaxial cable should be uti-
lized for inducted noise immunity. The 4-20 mA inter-
face requires approximately 3.8 V of drive voltage to
achieve 20 mA. thus making it compatible with most
current control loop configurations.
The input is isolated to allow the control module to be
inserted anywhere into a current loop that does not
exceed ± 30 volts from earth ground. The stroke rate
is displayed as a percentage of the fastest rate. The
stroke rate is limited to a minimum of 5.0% and a max-
imum of 100.0%. If the control current results in less
then the minimum of 5.0% the display will alternate
three dashes and the control current percentage, indi-
