CTI Janus Programmable Automation Controller IOG
3.2.4
Inserting the Battery
The Janus controller uses a non-rechargeable lithium battery which supplies power to save processor contents
after AC power is removed. The Janus controller is shipped with the battery installed in the unit. The battery is
accessible by removing the front panel battery cover. Rotate the cover counterclockwise to remove it by inserting
a coin or a screwdriver into the slot on the cover.
WARNING
The controller uses a 4.0 lithium battery, size AA. See Appendix D for additional battery specifications.
Batteries must be changed in an area known to be non-hazardous.
Do not attempt to charge the lithium battery. Charging a lithium battery can cause the battery to explode,
resulting in serious injury or death and/or damage to equipment. Replace the battery as shown above.
Lithium batteries contain flammable material. Do not puncture or crush the battery case, since this can
release the material and electrolyte. Exposure to electrolyte can cause eye and/or throat irritation. If the
electrolyte comes into contact with your skin or eyes, flush thoroughly with water.
Do not place batteries on a metal surface, as this could cause a short circuit. If a lithium battery short-
circuits, disconnect it immediately and move it to a well-ventilated area. Wear safety glasses and other
protective gear when handling a defective battery.
Do not use lithium batteries in a completely sealed container. There must be a means of relieving pressure
if the battery is exposed to high temperature or abuse.
The Janus controller mo
nitors battery status and provides ‘Battery Low’ indication when the battery has
approximately 30% of its usable life remaining. At this point, the battery will still provide adequate power for
power-loss conditions for some period of time (based on size of application and number of occurrences). However,
a replacement battery should be ordered and installed as soon as possible.
To replace the battery, insert the battery into the battery holder with the button end (+) facing outward.
Then
align the battery cover tabs with the slots in the holder, press the cover in until it is flush with the holder, and
rotate it 90º in a clockwise direction.
Batteries should be stored in the original shipping container in a cool well-ventilated area. Dispose of used
batteries according the instructions of its manufacturer and in compliance with all federal, state, and local
regulations.
