8.7. Transmitting unit power supply
Radio remote controls with portable transmitters are supplied with two rechargeable Ni-Mh batteries
and a dedicated battery charger.
8.8. Battery status of charge
The battery’s status of charge is shown by the YELLOW LED
on the transmitting unit.
A YELLOW LED OFF means the battery is charged.
A flashing YELLOW LED means the battery is low. Turn off the transmitting unit and change the
battery. The LED begins to flash when the battery has power left for approximately 10 to 15 minutes.
Note:
The yellow LED flashes with the specific sequences during special setup procedures and in the
case of system failure.
A low battery charge can also be indicated by an intermittent acoustic warning by connecting a horn to
the corresponding relay output on the receiver, which in this case, closes for 1 second every 8
seconds.
8.9. Changing and charging the battery
Shut-off the transmitter unit, remove battery from its housing and insert it into the battery charger.
In order to guarantee better battery duration and efficiency, it is best to use the charge until it drains
completely.
The battery charger must be powered by a conventional voltage line without significant fluctuations, in
order to not affect the smart charging process managed by the microcontroller.
The battery chargers CB36NIMH, CB3600AC e CB3600DC
for NiMH cells
are equipped with a green
LED that indicates that power is present and a yellow LED that flashes 4 times when the battery is
inserted (pre-charge) and remains on until charging is complete.
The battery charger is capable of detecting residual charge and battery capacity. The average charge
time for a battery that has been properly discharged is 2-3 hours, depending on the residual charge
and cell capacity. The charge cycle ends when the yellow LED shuts off.
It is possible that, while charging a battery that was completely empty, the flashing yellow LED phase
(pre-charge) lasts several minutes.
If the flashing persists, clean the golden battery contacts using a soft cloth. If this problem
continues, replace the battery with a new one.
It is best not to interrupt the charging by removing the battery from the housing or by shutting-off the
battery charger while the yellow signal LED is still on.
In order to extend battery life cycles, if possible, avoid charging batteries that are already completely
or partially charged.
The battery charger is designed for indoor use: do not expose it to the elements. To preserve battery
life, recharge the battery in a dry place and at a temperature between 5°C and 35°C (values
recommended by NiMH cells manufacturers)
The battery chargers CB37LION for Lipo and Li-ion cells
are equipped with a green LED that indicates
that power present and a blue LED that, after inserted the battery, if the voltage residual is below of
4,2V, remain on until charging is complete.
The battery charger is capable of detecting residual charge and battery capacity. The average charge
time for a battery that has been properly discharged is about 3 hours, depending on the residual
charge and cell capacity. The charge cycle ends when the blue LED shuts off.
The battery charger is designed for indoor use: do not expose it to the elements. To preserve battery
life, recharge the battery in a dry place and at a temperature between 0°C and 45°C (values
recommended by Lipo and Li.-ion cells manufacturers)
Warning: Explosion hazard if non-compatible batteries are used! Use IMET batteries only. See
Chap. 14 for information on the disposal of exhausted batteries.
