Series F4 Controller Setup Parameters
!
CAUTION: The Series F4 Controller has been properly configured by TestEquity to match
the chamber’s system requirements and to perform optimally over a wide
range of operating conditions. Improper modifications to these setup values
can result in erratic performance and unreliable operation. Setup examples in
the “Series F4 User’s Manual” are NOT applicable to this chamber. Do not
attempt to modify the setup values, unless you thoroughly understand what
you are doing. If there is any doubt, please call TestEquity before proceeding.
!
CAUTION: The “Series F4 User’s Manual” is a general manual and is written by the
manufacturer, Watlow, for a wide variety of applications and configurations.
Not all features or functions are applicable. Only the capabilities of a model
F4DH-CKCC-01, as described on page A.7 of the “Series F4 User’s Manual”
are applicable. “Cascade Control” as described on page 3.6 of the “Series F4
User’s Manual” is not applicable in this configuration. The “Retransmit”
function is available as an option.
!
CAUTION: The Series F4 alarms are configured for internal protection of the humidity
system. Do NOT change this configuration under any circumstances. The
independent EZ-Zone Limit Controller functions as the main system and
product protection device.
!
CAUTION: NEVER select “Full Defaults” in the Factory/Test Menu. “Full Defaults” are
NOT the TestEquity configuration parameters for this chamber. If you select
“Full Defaults”, you must reconfigure all System and Operation Parameters as
documented in the TestEquity manual, NOT the “Series F4 User’s Manual”.
TestEquity has configured the F4 Controller with the parameters as documented on the following
pages.
NOTE: If your chamber was ordered with the F4T Touch Screen Controller, see the
separate manual for that controller
