2. Primary Remote Switches:
A. Used with a Primary TIT Instrument - A Priamry Remote Switch may be connected to a TIT
channel on any appropriate Electronics International Instrument. This gives the TIT instrument
multi-channel EGT capability. Only the TIT or any EGT cylinder may be displayed on a Primary
TIT instrument. The channel marked "Primary" on the remote switch is used to display TIT.
B. Used with a Primary CHT Instrument - A Primary Remote Switch may be connected to a CHT
channel on any approprate Electronics International Instrument. This gives the CHT instrument
multi-channel CHT capability. Only CHT's may be displayed on a Primary CHT Instrument. The
channel marked "Primary" on the remote switch is used to display the primary CHT cylinder (i.e., if
cylinder number 3 is the primary CHT cylinder for your engine, cylinder 3 will be displayed on the
CHT instrument when the remote switch is set to the channel marked "3" or the channel marked
"Primary").
Note: When using a Primary Remote Switch, the switch must be left in the "Primary" posistion
during flight.
TIT
1. Maximum Operation TIT Limit (Red Line):
Do not operate your engine above the Maximum Operating Temperature Limit as indicated on the front
of this instrument. Operating above TIT Red Line can cause turbine housing and component failures,
detonation or preignition (which will destroy engine and turbine components), loss of engine power,
reduced turbocharger and engine life and can cause a fire hazard. It is essential to operate your engine
within its TIT operating limits. Electronics International’s TIT instruments give you three mechanisms
to detect an over-temperature limit (Red Line) condition.
A. The Large Digital Display gives you a fast and very accurate indication of your current tem-
perature condition. This instrument will display temperatures from ambient to 1999‘F in 1‘F
increments. This also allows you to interpret rate and trend information at a glance.
B. This instrument incorporates an Over-Temperature Warning Light. This light will come on any
time the TIT is above the Maximum Operating Temperature Limit as indicated on the front of this
insturment. This light provides the advantage of catching your attention without your having to
scan or interpret the display.
C. This insturment also comes with an External Warning Control Line. This line can be connected
to an external light in a control panel or mounted in front of the pilot. This control line will turn on
the external light any time the TIT exceeds the Maximum Operating Temperature Limit as indicated
on the front of this instrument.
