User manual FUTABA CDR5000

[. . . ] Thank you very much for purchasing a rapid charging & discharging equipment CDR-5000. The CDR-5000 features in rapid charging, rapid discharging and cyclic charging/discharging of NiCd and NiMH batteries used for motors, radio transmitters and receivers for radio control model applications. And the large LCD screen enables you to monitor various data and charts. Please read this instruction manual prior to the use of this product so that you would draw the maximum performance of the CDR-5000 while you keep the safety. Do not leave the CDR-5000 unattended while using it. [. . . ] And charging will start. [Discharging at TX/RX] 1)Push "TX/RX D-CHG" key. Caution for discharging: Sensing the voltage of the battery while discharging at TX&RX, CDR-5000 automatically calculates the voltage level that stops discharging. It suggests that if you discharge a battery that has been already discharged or a battery whose voltage is already very low, the battery will be over-discharged. Never do an additional discharging If the voltage of a battery under discharging declines in the early stage and becomes lower than 0. 8V/cell, stop discharging. It is recommended to use a cooling fan to keep the temperature of a battery low while discharging in Cycle Mode, because the temperature of the battery under Cycle Mode generate a large amount of heat due to continuous operation. And it is also recommended that "CYCLE DELAY" in the "INITIAL SETTING" be set "ON" during the usage. 21 CDR-5000 Functions 4. End of Charging/Discharging [End of charging at DX] Alarm buzzer will beep as soon as charging at DX is over. Charging process is now completed. *If the "BUZZER" is set to "OFF" in the "INITIAL SETTING", there will be no alarm buzzer. <How to return to "DX DATA" screen> Push "Data" key to return to "DX DATA" screen from "FINISHED DX CHARGE" screen. CUTOFF BY This is show the item that is detected at first among the items related to CHARGE CUT in the "SETUP" screen. *DELTA PEAK (0 DELTA VOLT. ): When DELTA PEAK was used for CHARGE CUT. *LOW DC 12V: When the voltages drop of a power source was used as a parameter for CHARGE CUT. 22 CDR-5000 Functions POWER LEVEL This is the number that represents the status of a battery under charging by calculating from the voltage drop of the battery to which a certain constant load is applied. Take into consideration this number as a guide for daily maintenance of batteries. FINISHING BATTERY TEMP This shows the temperature of a battery when the charging of the battery is completed. [End of discharging at DX] Alarm buzzer will beep as soon as discharging at DX is over. Discharging process is now completed. *If the "BUZZER" is set to "OFF" in the "INITIAL SETTING", there will be no alarm buzzer. <How to return to "DX DATA" screen> Push "Data" key to return to "DX DATA" screen from "FINISHED DX DISCHARGE" screen. CUTOFF BY This shows the item that is detected at first among the items related to DISCHARGE CUT in the "SETUP" screen. POWER LEVEL This is the number that represents the status of a battery under discharging by calculating from the voltage drop of the battery to which a certain constant load is applied. Take into consideration this number as a guide for daily maintenance of batteries. This shows the temperature of a battery when the discharging of the battery is completed. 23 CDR-5000 Functions *VOLT: When the voltage level was used for DISCHARGE CUT. *TIMER: When timer was used for DISCHARGE CUT. [End of charging at RX/TX] Alarm buzzer will beep as soon as the charging at TX/RX port is over without fail after detecting "DELTA PEAK". Charging process is now completed. *If the "BUZZER" is set to "OFF" in the "INITIAL SETTING", there will be no alarm buzzer. <How to return to "TX&RX DATA" screen> Push "Data" key to move to "DX DATA" screen from "FINISHED TX & RX CHARGE" screen, then push "Data" key again to return to "TX&RX DATA" screen. CUTOFF BY This shows a detected item such as bellow. *DELTA PEAK: This message will be shown when CHARGE CUT is carried out in proper way by "DELTA PEAK". *LOW DC 12V: This message will be shown when CHARGE CUT is carried out by the drop of a power source. Caution: If the output voltage increases abnormally, charging will be forced to stop as the "FINISHED TX & RX CHARGE" screen will not be shown, MODE indicator changes from "CHARGE" to "READY" with an alarm buzzer. 24 CDR-5000 Functions [End of discharging at TX/RX] Alarm buzzer will beep as soon as discharging at TX/RX is over. And the "FINISHED TX & RX DISCHARGE" screen will be shown. Discharging process is now completed. *If the "BUZZER" is set to "OFF" in the "INITIAL SETTING", there will be no alarm buzzer. <How to return to "TX&RX DATA" screen> Push "Data" key to move to "DX DATA" screen from "FINISHED TX & RX DISCHARGE" screen, then push "Data" key again to return to "TX&RX DATA" screen. 5. Cycle Charging/Discharging [Cycle Charging/Discharging at DX] 1)Push "DX CYCLE" key. 2)Either the blue LED of "DX Discharging" or the red LED of "DX Charging" turns on. [. . . ] "SHORT or REVERSE!" This warning indicates an electrical shortage at output terminals of DX or TX&RX, a wrong polarity connection of a battery or over-discharge. Check the conditions of terminals and the battery condition. "INPUT POWER SUPPLY VOLTAGE IS TOO LOW!" This warning appears when the output voltage of a power source for charging drops. "THERMO STAND DISCONNECTED or TEMPERATURE OVER RANGE!" This warning appears when the Thermo Stand (option) is disconnected from the CDR-5000 and when the temperature measured by it exceeds the specified temperature. To clear the warning, push "Data" key or plug the Thermo Stand into the CDR-5000. [. . . ]
