Operation
The basic operation of the KSC-14 involves trickle recharging when a battery pack is inserted. Rapid recharging starts when the recharging start switch is pressed. Two battery packs can be recharged in sequence, and the recharging status for each channel is indicated by an LED. Two recharging currents are available, and the voltage for short judgment can be changed according to the battery type. The recharging operation follows the sequence: battery pack insertion, trickle charging, recharging start switch ON. The LED indicates the recharging status for each channel, lighting in red, green, or orange. The recharging start switch is effective for unrecharged batteries only, and sequential recharging is performed if the switch is pressed when one battery pack is being recharged and the other is waiting. The battery pack is identified by checking the connection of the battery pack terminals. The voltage for short judgment is changed according to the battery type, and if the short detection time of 20 minutes is exceeded, an error is displayed. The timer is fixed at 120 minutes.
