2.8 Battery Low Voltage Protection

(BLVP or commonly known as an LVD)
The PM435 unit has a built-in battery low voltage protection relay. It will disconnect the load once the battery voltage
drops below the threshold voltage. The default setting is 10.5Vdc and it can be changed by crystal central monitor or
mobile APP from 10.0Vdc to 11.7Vdc.
2.9 Battery Switch
The PM435 unit offers a convenient way to switch off the output of the service battery on-board. It protects the
service battery from being drained by electronics on board, completely isolating the battery. PM435 unit also supports
a remote manual battery switch. Before using the remote switch, ensure the 'switch selector' is set to 'Remote'. The
switch is only effective when the system has no other energy resource for the load except the battery.

2.10 Precise Battery Measurement

PM435 unit has a battery measurement system controlled by microprocessor. It measures battery voltage, charge/
discharge current, remaining AH and display time to go.
Compared to conventional indicating meters, a small current can be measured and read accurately with this device.
With this feature, it highlights faults, alarms and installation errors.
ATTENTION: If you have loads connected directly on battery instead of PM435 Power Management System, the
measurement will not be accurate.
2.11 Scene mode setting
The PM435 supports the preconfigured scene mode for multiple loads controlled. There are two modes programmed
in MSP10 and MSP2.
"Night mode" on 10 Position Switch Panel (not inc. PM435-BT)
or "Silent" mode on the Monitor
By pressing "Night mode" on the switch panel or "Silent mode", all LED indicators of the 10 Position Switch and
backlight of Monitor will be turned off; in the meantime, the output power of PM435 will be reduced in order to stop
the fan for a noiseless night.
"Night Light" on 2 Position Bedroom Switch (not inc. PM435-BT)
By pressing "Night Light", the Ceiling light will be turned on, and by holding down "Night Light" button to adjust a
proper brightness for night without disturbing other's sleeping. The brightness setting will be remembered.
