6.3.7>.Record and display discharging time if disabled Discharging Time OP when short press button SET. Clear time if at next discharging or exit discharging time display interface.
6.4>.Turn ON Delay Time dOP: Set the delay interval between the first and the second discharging. The time range is 0~999second.
6.5>.Discharge Turn ON Forced Start Time FOP:
6.5.1>.This function is used to prevent the device from starting instantly and reduce the battery voltage, so that it is lower than the Lower Limit Voltage Value dn and causing the module to automatically turn off the output and causing the battery can not discharge properly.
6.5.2>.The module will check the battery voltage again if enabled Discharge Turn ON Forced Start Time function.

11.Frequency asked questions:
1>.What is the control voltage range? What is the applicable battery range?
Q: Control voltage range is DC 6V-60V. But battery voltage max is 48V. Because the voltage of 48V battery is 60V after fully charged.
2>.Why relay is automatically turned on and off continuously after power on and flashing light?
Q: This is because your charging current is too large or the battery capacity is too small that cause the battery voltage to immediately exceed the Lower limit voltage ‘dn’ value and then relay will OFF.But the voltage drops quickly to the Lower limit voltage ‘dn’ after Relay OFF and then start to charging.Cycle and cycle.
At this point you have to reduce the charging current.Usually the charging current is 10-15% of the battery capacity.For example, if the battery capacity is 20AH, the charging current is 2-3A.
Note that high current charging can cause the battery to heat up, aging, bulging or even exploding.
3>.What control method?
Q: This is the voltage control.For example:Lower limit voltage ‘dn’ is set to 12.0V.Upper limit voltage ‘UP’ is set to 14.5V.It will close output when the voltage is charged to 14.5V.Relay will ON and begins to charge when the voltage is reduced to 12.0V.
4>.Can it be automatically cycled?
Q: Yes,it can.Voltage control mode only controls turn-off and turn-on.
5>.Can it limit the current?
Q: It can't limit current, the charging current is completely dependent on your charger.
6>.Can I charge a 24V battery by inputting 12V?Or charge a 12V battery by inputting 48V?
Q: This is a simple voltage controller just for ON/OFF.It can not change output voltage.So what kind of charger should you prepare for charging the battery!
