Process Ports
Your instrument is shipped with plastic plugs fitted in the port openings. To
lessen the chance of contaminating the flow stream do not remove these
plugs until you are ready to install the device.
Controllers with M5 (10-32) ports have O-ring face seals and require no sealant
or tape. Do not use tape with welded or O-ring fittings.
For non M5 (10-32) ports use thread sealing Teflon® tape to prevent leakage
around the port threads.
Do not wrap the first two threads. This will minimize the possibility of getting
tape into the flow stream and flow body.
Warning:
!
compounds can cause permanent damage to the controller should they get into the
flow stream.
When changing fittings, carefully clean any tape or debris from the port
connections.
Maximum Pressure
Both the valve and the sensor can be damaged from over-pressurization. The
valves on an EPC or EPCD are rated to 150 PSIG, unless custom-ordered. The
burst pressure of the pressure sensor is 3x the full scale, and permanent
damage will occur if this is exceeded.
Pressure Controller Operation
The response time of the system will depend on the size of the volume being
controlled, the operating conditions, and the PID tuning of the device. The
controllers are intended for use with clean, non-corrosive gases only.
Do not use pipe dopes or sealants on the process connections, as these
