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 F4T1L2EAA2D7030 are
applicable.
!CAUTION: The Series F4T “Alarm” functions are NOT used in the chamber’s safety
system. TestEquity does NOT recommend using the Series F4 alarm function
as the main protection device. The independent EZ-Zone Limit Controller
functions as the main protection device.
!CAUTION: When using Part Temperature Control, the Part Thermocouple must always be
attached to the device under test (DUT). Failure to do this will result in erratic
temperature control. If you do not want to attach the thermocouple to the
DUT, then select “Air Control” on the F4T.
!CAUTION: When using Part Temperature Control, the Part Thermocouple must never be
placed outside the chamber. Failure to do this will result a thermal runaway,
up to the limits set on the Limit Controller.
!CAUTION: The Series F4T Temperature 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 Series 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.
