TC7000

Battery Deep Discharge. 

WARNING. ONLY REMOVE THE BATTERY IN A SAFE AREA.

TC7000/7150 monitors battery status using a coulomb counting technique which measures the amount of energy used by the camera rather than the actual status of the battery itself. This is different from many other non-Intrinsically Safe devices and is a result of the certification restrictions. In order for this technique to function correctly, the camera requires a fully charged battery to be inserted.

To help prevent the battery going into deep discharge which can cause damage, TC7000/7150 incorporates a backup shutdown timer. After 6 hours runtime, the camera shuts down automatically at which point, the battery should be removed and recharged as soon as is safely possible.

If a partially charged battery is inserted, the battery status indication on the camera screen will be removed and the shutdown timer will timeout after 2 hours, this mode of operation is not recommended and may cause result in the battery going into deep discharge which renders the battery unsafe and in need of replacement*

Even with the camera powered off, the Intrinsically Safe safety circuits are still functioning; helping to ensure the camera is in a safe state. The trade-off for this continuous safety is that the battery is being drained even with the camera powered off, which can also lead to deep discharge. As such, at the end of a working period, the battery must be safely removed from the camera and placed on charge, never leave the battery in the camera overnight, even if the camera is powered off.

CAMERA OPERATION

ALWAYS ENSURE A FULLY CHARGED BATTERY IS INSERTED INTO THE TC7000/7150 OR POOR RUNTIME AND/OR BATTERY DAMAGE MAY OCCUR.

TC7000/7150 will prompt the user on initial camera power up, to confirm that a fresh battery has been installed;

If the user answered Yes, then the battery charge status indicator will be displayed as normal showing a full charge and the six hour safety timer will start.

If the user answers No, then the camera will display a second warning screen, informing the user that the camera will allow power up, but this mode of operation is not recommended and damaged caused may not be covered by the Warranty. If the user continues the power up routine in this mode, the battery charge status indicator will not be displayed as the camera has no method of measuring the charge and the six hour safety timer will be reduced to two hours. NOTE, this is not the preferred method of use for the camera and battery damage may still occur.

If on power up yes is entered numerous times for the question “has fresh battery been installed” and it is the same battery which has not been charged then the battery can be run down into deep discharge to a state where it is not recoverable and will not charge. In this case a new battery will have to be put in the unit.
