Chapter 1 – Safety Instructions
Introduction
Follow all CAUTION notices to prevent damage to the chamber or your test sample. Failure to
follow all CAUTION notices may void your warranty. CAUTION may also indicate a
potentially hazardous situation which, if not avoided, may result in minor or moderate personal
injury.
The safety alert symbol ! precedes a general CAUTION statement.
Safety Notices
! CAUTION: The Watlow F4T Manuals are written by the manufacturer, Watlow, for a
wide variety of applications and configurations. Not all features or functions
are applicable. Only the capabilities of model F4T1L2EAA2A1017 (for
Temperature Chambers) or F4T1L2EAA2B2018 (for Temperature/Humidity
Chambers) are applicable. “Cascade Control” and “Retransmit” functions are
available as options.
! CAUTION: The F4T “Alarm” functions are NOT used in the chamber’s safety system.
TestEquity does NOT recommend using the F4T alarm function as the main
protection device. The independent EZ-Zone Limit Controller functions as the
main protection device.
! CAUTION: The F4T 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
Watlow F4T Manuals 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: Configuration files are unique to each particular model chamber and must
NEVER be transferred to a different model chamber.
! CAUTION: NEVER select “Factory” in the “Restore Settings From” prompt in the Device
Details menu in Composer Software. This will erase all controller
configuration settings. The chamber will not work if you do this.
