Chapter 4 – F4 Temperature/Humidity Controller
TestEquity 123H Temperature/Humidity Chamber Page 4-19
Operations Page
The Operations Page provides access to menus for control tuning (PID) and controller alarms.
TestEquity has configured the security to require a password for access to all parameters in the
Operations Page. You must call TestEquity at 877-512-3457 or 805-480-0638 to obtain the
password.
!
CAUTION: The Series F4 alarms are configured and dedicated for internal protection of
the humidity system. Do NOT change their configuration under any
circumstances. The independent EZ-Zone Limit Controller functions as the
main protection device.
!
CAUTION: The Series F4 Controller PID values have 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 values can result in erratic performance and unreliable operation. Do
not attempt to modify the PID values, unless you thoroughly understand what
you are doing. Setup examples in the “Series F4 User’s Manual” are NOT
applicable to this chamber. If there is any doubt, please call TestEquity before
proceeding. The correct values are documented in the “Series F4 Controller
Setup Parameters” section of this manual.
!
CAUTION: The Autotune PID function is not appropriate for use in this chamber. Using
this function will result in tuning values that will not work correctly.
Setup Page
The Setup Page provides access to menus for configuring the controller hardware. TestEquity
has configured the security to require a password for access to the Setup Page. However, there
will be times when entry into these menus is necessary. For example, you may need to gain
access to Setup Page in order to change from °C to °F display, or to change the time or date. You
must call TestEquity at 877-512-3457 or 805-480-0638 to obtain the password.
