Battery Recharging - Delta DE212 GLOBAL Operation And Installation Manual

3.5 B R
ATTERY ECHARGING
1. Before the transmitter is used for the first time, it should be recharged with continues charging for 3 hours.
Place the transmitter in the charger on the receiver. Wait 30 seconds till the CH lamp start flashing, press the
CODE button on the receiver for some seconds, and the CH lamp will start to light constantly, indicating that
the transmitter battery is charged with maximum current. If the transmitter is left in the charger, this state
will last for 3 hours leaving a completely fully charged battery. Note, if the battery is not completely empty,
two hours charging is normally sufficient to start operation. Do not repeat the 3-hour full charging unless the
red LB lamp on the transmitter is flashing.
2. When the transmitter is placed on the receiver charge station, the transmitter battery will be recharged
according to the duration the transmitter has been used. The recharging will replace the used battery energy
actually used during operation. This type of charging will secure maximum battery capacity and lifetime.
Every time the transmitter is placed in the charger, it charges for 30 seconds with full current. After 30
seconds, and if the transmitter is unused, the charge current is reduced to maintenance charging and the CH
lamp will start flashing.
If the transmitter has been in operation longer than 5 minutes, the CH lamp will light constantly, indicating
that charging is at full current. When the battery energy has been restored, charging is reduced to
maintenance as long as the transmitter is in the charger. If the power of the receiver is switched off, stored
information regarding transmitter operation time, is erased.
The charging of the transmitter battery is controlled by the software in the receiver, and it is recommended
3.
always to leave the transmitter for charging. The charging current is limited to 50mA during full charge, and
the charging time is regulated by the receiver software. The battery temperature will never rise above +50ºC
and will not be a hazard for the EX environment. In case of a short circuit of the battery connections, a build
in temperature and current fuse, in the battery will secure a temperature allowable in EX environment.
With a fully recharged battery the operational time is 12 hours. This means that the Deadman button on the
transmitter might be held operated for 12 hours before it stops transmitting.
Note that operation of the transmitter in low temperatures reduces the capacity of the battery down to 30%
of normal capacity at room temperature. At temperatures lower than -20C, the battery may "freeze" and
lose all its capacity.
NOTE: Charging the battery, should take place at temperatures not lower than 0ºC and not higher than
4.
+50ºC. Charging outside these limits will results in very low charging current, or no charging of the battery at
all. The battery will however not be damaged.
When operating at low temperatures, lower than 0ºC, do not leave the transmitter in a cold driver's cabin
overnight or for a long period of time. Take the transmitter inside to keep the battery warm. Charging of the
transmitter will normally be finished before the car is back to the depot.
It is recommended to use a CH300-230/115V mains charger, if the receiver is installed so that the
temperatures often is outside the recommended temperatures.
Use only Delta chargers for charging the transmitter, other chargers might overload the battery and the
ATEX/IECEx certification is no longer valid.
5. The type of battery used is a 3,6V 300mAh NiMH. The battery is a part of the end section of transmitter
house. The connection to the printed circuit board is by a small connector. Defective batteries must be
disposed at a proper place, where batteries can be disposed. Please see chapter 8 for further information.
A normal lifetime for a battery is approximately 500 recharging.
NOTE: After July 1. 2003, the new ATEX norms are activated. For the DE212 system, the battery module and
the transmitter circuit board must be replaced with parts produced according to this norms. This means that
repair of the TX212 must take place at Delta RC AS or by a Delta RC AS appointed dealer. Otherwise ATEX
certificate is no longer valid.
