Steps to install and configure a new application:
1.
Mount the module in a suitable location
2.
Connect the power supply and valve solenoids
3.
Adjust current range to match valve
4.
Adjust PWM/Dither to optimize performance of the valve
5.
Adjust analog input to voltage or current, and scale input to desired system speed
6.
Adjust ramping (if desired)
7.
Adjust internal monitor functions (if desired)
6.
Adjust customized current to of valve flow gain (if desired)
All parameters are adjusted using VEA-USB programming cable and CHI-PC Microsoft Windows
application:
Module Mounting Location:
This module is to be mounted in a cabinet for protection from the local environment.
Ensure there is adequate free space around the module to allow for cooling air flow.
This module is designed to snap onto an industry standard 35mm DIN rail.
Do not mount near other modules that emit high power electrical interference, such as motor
controllers and high power contactors.
Power Supply:
This module is designed to operate on DC power from a regulated power supply ranging from 12
to 30 volts.
A 3 amp medium action fuse is recommended in the “+” power supply line.
Adjust MODE to STD or EXP:
Simple parameters may be adjusted while in STD mode.
EXP mode allows for more complex parameter adjustments.
MODE parameter valid options are STD and EXP. Default is STD.
TS parameter:
TS sets the sample time of the closed loop control system. Valid settings are from 5 to 30 Units
are msec. Default is 10. It is advised to keep this parameter set to 10.
