TECHNOLOGY
13.22. Charge Circuit
Charger uses current-control-circuit to prevent sudden-recharge and use voltage-steady-circuit to
prevent over-recharge.
Charge inspection use 24Vac the same power as Relay Module has.
Disconnecting CN11 may cause spark, turn off NFB1(Battery Switch) and NFB2(Ac Power
switch) before disconnect CN11. Limit Current measuring should be tested on 10Ω in series with
CD Ammeter.
Charge Voltage : 27.5Vdc(±0.5V)
Charge Current : 300mAdc(±50mAdc)
NOTE :
The battery charger is fully temperature compensated.
Battery charger capacity can be changed by request of a user.
13.23. Battery Change
Battery Mounting consists of two of Bolt M6-15L. Battery Wire consists of M5 Bolt & Nut and
is connected to Battery Terminal. Bolt can be replaced using with (+) screwdriver.
For Battery wire de-assembling, disconnect Jumper wire first and disconnect CN11 wire(red and
black). When CN11 is disconnected first, battery short is considered in case of worker’s mistake.
For Battery wire connection, connect CN11 wire (red and black) first and connect Jumper wire
later. Reference “Figure 13-19. Battery”
13.24. Battery Protection
Battery protection is to protect the battery from over-discharge by disconnecting the battery from
the control circuit when AC power is lost and before the battery is completely discharged. CPU
measures the battery voltage and when the battery is below 21 volts, timer is operated and after
10 minutes, Latch Relay is set to disconnect the battery circuit.
On Power Down status, if the external power is re-supplied or the Power Switch is changed from
OFF to ON, Control Module is operated as normal.
When AC Power is not supplied, in order to operate it by Power Switch, OFF for 5 seconds and
turn it ON. When it is turned ON without Battery, it is Power downed after 10 minutes.
