Pulsafeeder Pulsa Series Cruise Control - Manual (Page 5)

1. Single Page Start-Up
Although the Cruise Control
™ is factory set to your specifications, it is always good practice to verify jumper
settings to insure nothing was removed, changed, or damaged during shipping or installation. Once a visual
inspection is complete, connections can be made. Refer to Section 4 for terminal block layout. Ensure that all
electrical wiring meets applicable local and national electrical codes as well as appropriate facility standards.
Motor and Control Connections
1. Verify that jumper JP8 on the DC SCR drive for motor armature voltage is set properly to match the
motor nameplate data (LO = 90VDC, HI = 180VDC).
2. Connect the motor armature, ground, and shunt wires (where applicable) to the proper [black] terminal
blocks.
3. Connect tachometer (optional) to the proper [orange] terminal blocks.
4. Verify that Jumper JP4 on the drive is set for tachometer feedback if applicable.
5. Verify that Jumper JP3 on the drive is positioned properly for the tachometer feedback range.
6. Connect a two-wire dry contact drive start input (or the optional 24VDC or 120VAC drive run input) to
the proper [yellow] terminal blocks. Note that 24VDC and 120VAC signals are polarity sensitive.
7. Connect external 4-20mA speed reference [blue terminal blocks].
8. Connect the drive status output [green terminal blocks].
9. Connect any other additional optional inputs and outputs.
Pre-Sets
10. Verify that the "Drive Start" selector switch is in the "OFF" position and that the "Drive Speed" selector
switch is in the "LOCAL" position. The speed potentiometer should be in the full counter-clockwise
position.
11. Verify that Jumper JP11 on the drive is set for the proper system input voltage.
Power Connections
12. Connect power to the main disconnect, or if a disconnect was not specified, to the terminal blocks located
in the upper right corner. For a single phase system, only the hot wire is connected to the disconnect. The
neutral and ground wires are connected to terminal blocks.
13. Turn on disconnect power and verify power is present in the panel. A "Power On" pilot light may be
included as an option.
Testing
14. Verify that it is safe to run the pump within the system, or that the pump is properly isolated from the
system.
Remember that diaphragm metering pumps should not be run against closed valves on either side
(suction and discharge) of the piping system.
15. Put the "DRIVE RUN" selector switch into the "ON" position and slowly turn the speed potentiometer
clockwise until the motor runs. Perform other testing and adjustment as required.
