Campbell Scientific T.Weather T107 Toro Weather Station - Manual (Page 67)

T107 Weather Station
Replace the battery when voltage is approximately 2.7 V. If the lithium cell is
removed or allowed to discharge below the safe level, the T107 will still
operate correctly while powered. Without the lithium battery, the clock will
reset and data will be lost when power is removed. Contact your local Toro
distributor.
Toro recommends factory replacement of the lithium
battery. Misuse of the lithium battery or installing it
improperly can cause severe injury. It is a fire, explosion,
and severe burn hazard! Do not recharge, disassemble,
heat above 100°C (212°F), solder directly to the cell,
incinerate, nor expose contents to water. Lithium batteries
need to be disposed of properly.
The lithium battery contained inside of the T107’s canister is pn 13519.
TABLE 4-1 lists the specifications of the battery.

4.2 Troubleshooting
4.2.1 No Response Using the CR1000KD Keypad
Check keypad response after each of the following steps.
A. Make sure the battery has been installed and the PS100 power switch is set
to “ON” (Section 2.8, Battery Installation).
B. Use a voltmeter to measure the voltage on the 12 V and G terminals (see
FIGURE 2-44); the voltage must be between 9.6 and 16 Vdc.
Use a voltmeter to measure the voltage on the 5V and G terminals (see
FIGURE 2-44); the voltage must be between 4.9 – 5.1 Vdc.
C. Disconnect the Temp/RH sensor from the back of the enclosure.
D. Disconnect the 9-pin ribbon cable from any communication option used
with the station so that only the keypad is attached to the 9-pin plug in the
lower right hand corner of the enclosure.
E. Cycle the power to the datalogger by switching the PS100 power supply to
“OFF”, then to “ON” or disconnecting and reconnecting the battery plug.
Keypad should power up and the Campbell Scientific logo and text
appears on the display.
