Temperature Status and Overheat Indicator
All DigiTrak transmitters are equipped with an internal digital thermometer. The temperature
displays on the bottom right of the receiver and remote display screens next to the transmitter
temperature symbol . Normal drilling temperatures range from 64 to 104° F. Suspend
drilling when temperatures exceed 97° F to permit cooling.
A small triangle beside the temperature icon indicates whether the temperature is trending
up or down since the last reading.
Note Because the digital thermometer is inside the transmitter, temperature increases
due to external drilling conditions will take time to transfer to the transmitter.
Resolve increases in temperature quickly to avoid irreversible damage.
If the temperature reaches 118° F, the thermometer icon will change to show that the
transmitter is becoming dangerously hot . The transmitter must be allowed to cool
immediately or it will be damaged.
To cool the transmitter, stop drilling and retract the drill bit a few feet and/or add more drilling
fluid.
Transmitter Temperature Warning Tones
The Falcon F5 receiver and remote display emit the following audible tones to indicate
increases in the transmitter temperature:
Icon
Temperature
Warning Tones
Below 61° F
None
61–97° F
Double-beep sequence (beep-beep) for every 7° F increase in
temperature.
104–111° F
Two double-beep sequences (beep-beep, beep-beep) for every
7° F increase in temperature. Action is required to cool the
transmitter.
118–133° F
Three double-beep sequences (beep-beep, beep-beep, beep-
beep) for every 7° F increase in temperature. Cooling is critical to
avoid irreversible damage.
flashing
Above 140° F
Three double-beep sequences every 5 seconds on the remote
display, and every 20 seconds on the receiver. This warning
signifies dangerous drilling conditions; irreversible damage may
have already been done to the transmitter.
220° F
None: transmitter overheat indicator (temp dot) turns black.
