CPS Cleanout
CPS Cleanout is a function that pushes contaminants from the sump of the CPS out the drain tube. A low-
pressure setpoint is automatically set to establish a flow to clean out the CPS for the specified amount of
time. This same function occurs each time the CPS is controlling downward or venting with the pressure
less than 170 kPa (25 psi).
Disconnect the Product
To disconnect the Product, ensure that the system is vented and then disable the CPS in the controller
settings. Make sure that the CPS is disabled in the firmware if it is physically disconnected from the
controller. Failure to do so could result in the controller not being able to vent pressure. Once disabled in the
firmware, the CPS can be disconnected both electrically and pneumatically. Do not leave the CPS physically
connected to the controller if it has been disabled in the firmware.
Maintenance
Inspect the drain tube and waste bottle/container after use. If the drain tube or liquid from the tube shows
signs of contamination (particulates or oily substances), the coalescing filter and mesh filter should be
inspected. The frequency of inspection will vary depending on the condition of Devices Under Test (DUT)
that have been calibrated. With time and experience, you can determine if a regular inspection interval is
more appropriate, or if the filters should be inspected when the waste bottle/container is full.
Push on the plastic ring on fitting
to disconnect drain tube
, and pull gently on the drain tube. See
