ELECTRICAL CONNECTIONS
1.
Make sure all electrical power is OFF while making electrical connections. Improper connections can damage the QPV.
2.
Identify the command input and analog output signal types for your specific QPV part number using the ordering information
section on the last page of this sheet. Confirm this against the calibration card included in the packaging.
3.
Use the information below to wire the QPV according to your specific part number and signal type(s).
NOTE: ALL COLOR CODES RELATE TO THE FACTORY WIRED QBT-C-x POWER CORD.
VOLTAGE COMMAND VALVES
All voltage command QPV1’s use single ended voltage, meaning
the DC Common pin (Pin 1) is the common reference for both
power and command. Pin 1 is used as both the command signal
common and power supply common.
CURRENT COMMAND VALVES
All current command QPV1’s use a differential current loop
scheme (not isolated), meaning current flow is from Pin 4 to Pin
2 on the QPV valve. Some applications may require the common
of the power supply that provides loop power for the 4-20mA
command to be tied to power supply common.
