PANEL BUTTON OPERATION

PANEL BUTTON OPERATION
Pressing and holding the button for more than 3s, all LEDs are illuminated to enter into lamp test mode; Keep pressing and don’t release, after 7s all LEDs are flashing (once per 500ms) to enter parameter setting status, and release the button; At this time if users don’t plan to set paramters, press button, and all LEDs flash rapidly for 5 times (once per 200ms) to return back to normal testing mode. At the status of lamp test, release button and controller goes back to normal testing mode. After entering parameter setting status, if parameters are not set, controller will automatically go back to normal testing mode after about 1 minute and 30 seconds.

MASTER SETTING
First of all make controller enter parameter setting status, and then conduct the settings. Procedures of setting “1# Master ”, “ Master ” and Each Backup

• Press , and at the sam e time, when 1# 1#/#2 power indicator and auto indicator are illuminated; release the three buttons, then the auto indicator and 2# power indicators extinguish, 1# power indicator illuminates, which means the controller master setting s tatus is entered
• Pressing can circularly set 3 conditions of power supply.
  • 1# Master : 1# power indicator illuminates and 2# power indicator extinguishes
  • 2# Master : 2# power indicator illuminates and 1# power indicator extinguishes

OPERATION CONTROL

When the controller is running, pressing key can set the controller to Auto mode and auto status indicator is illuminated. The pressing key can set the controller to Manual mode and the manual status indicator is illuminated. In auto mode, the controller can automatically transfer the load to 1# power supply or 2# power supply. When it is set to Auto Transfer Auto Restore, master power is normal, and the controller will transfer to master power in priority. When it is set to Auto Transfer Non-Restore, the controller only transfers to backup power, and master power transfer can only be controlled manually. Each Backup is mutually backed up for dual power sources. When 1# power is abnormal, and 2# is normal, the switch will transfer to 2# power supply, and vice versa. When it is set to Each Backup, the controller will not detect Auto Transfer Auto Restore settings.
In Manual mode, press key and load will be transferred to 1# power supply; press key and load will be transferred to 2# power supply.
