Description of operation
The Prism Expeditor is a valve monitoring and control package for linear
actuators that provides open/closed and intermediate positioning
functionality. Basic operation and intermediate control is accomplished
by 24VDC and a 4-20mA output signal from a control system.
Basic operation
The Prism Expeditor module is powered through the VDCIN terminals
and 24VDC must be present in order to calibrate the unit. The
CNTRLIN signal is also required for basic operation of the unit.
To stroke the valve fully closed position, apply a 4mA signal. To stroke
the valve fully open, apply a 20mA signal.
Intermediate position control
Intermediate positioning is accomplished by varying the 4-20mA
signal between 7.2mA and 16.8mA.
Note
Applying an out of range 4-20mA signal (<3.4mA or >21.1mA)
will drive valve to the 0% position and unlock the Wireless Link
control override functionality. Wireless functionality allows remote
monitoring, position control and TEACH capabilities. See page22
for Wireless Link user guide.
WARNING
Do not apply external power to the primary or secondary
solenoid terminals. This will cause permanent damage to the unit.
Calibration
The VDCIN terminals must be connected to a 24VDC power source
and unit connected to supply air.
1. Actuate the valve to the 0% position, red LED will be lit.
2. Press and hold the TEACH button for 2 seconds. The valve will
cycle open and closed one or more times while determining the
valve operating characteristics. The red, green, and yellow LEDs will
ash intermittently during these cycles.
3. Calibration will nish with the valve at the commanded position
and the appropriate LED will be lit.
