Troubleshooting and Maintenance
Issue:
My pressure controller disagrees with another device I have in line.
Action:
Pressure devices can normally be compared against one another provided there are no leaks between the two devices.
Another possibility is an improper tare error (
).
Issue:
Can I use the controller with other gases or liquids?
Action:
Yes for gases, maybe for liquids. Your pressure controller is designed to operate independent of the media being
used. One thing to check before changing gases or liquids is the chemical and material compatibility of the gas being
used with the wetted materials inside the controller. We also recommend contacting support (
) before
switching over to liquid pressure control.
Serial Communications
Issue:
I can’t communicate to the device when it is connected to my PC.
Action: 1.
Make sure the baud rate your software and COM port required is the one your pressure controller is using (

→
RS-232 Serial
or
RS-485 Serial
→
Baud Rate
).
2.
Check the unit ID (
MENU
→
SETUP
→
RS-232 Serial
or
RS-485 Serial
→
Unit ID
) to make sure you are addressing
it properly with your serial commands.
3.
Check the pinout (common pinouts are listed starting on
4.
Make sure the COM number matches the one your software is using to connect to the pressure controller.
5.
On the external serial communications device (computer, PLC,
etc.
), be sure that the pressure control (handshaking)
settings are set as on
