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.
3.2.2Analog 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).

!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)

!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-
