Backup Battery Replacement
WARNING! Before disconnecting or connecting equipment, switch
the power OFF and, if possible, lock it out. Assure the area is in a
non-hazardous condition before beginning the installation of any
new equipment or repairing existing equipment. Bypassing these
precautions may present an environment in which explosive
hazards are present. If you are working in a hazardous location,
take the appropriate precautions to assure the safety of all
personnel and equipment.
The TTD Annunciator contains a Backup Power Battery (shipped loosed
with the TTD annunciator) located in the power supply module.
While this battery has a potential life of up to 1 year, it may require replacement. The LOW
BATT icon will appear when the internal backup battery voltage is below 5.0 volts. If the battery
is missing or the voltage falls below 4.6 volts, the LOW BATT icon will
blink. Replace the battery when the LOW BATT icon displays in the
lower left corner.
NOTE: Internal backup battery not required for normal operation. Backup
battery supplies power to operate TTD annunciator when CD Ignition is the only
source of power and it is not operating (Shutdown).
When CD Ignition or DC voltage is present, power is not consumed from the internal backup
battery.
