Minuteman UPS MBK-E SERIES Turning The Unit On/Off, English, ON / OFF / Test Button, Self Test

English

TURNING THE UNIT ON/OFF

ON / OFF / Test Button

Press and release the ON/OFF/Test Button after one beep to turn the UPS ON and supply power to the load. The load is immediately powered while the UPS runs a two-second self test. Press and release the ON/OFF/Test Button after one beep to turn the UPS OFF. The UPS will continue to charge the batteries whenever it is plugged into an AC outlet and there is AC present.

SELF TEST

The self test feature is useful to verify the correct operation of the UPS and the condition of the batteries. With the UPS in the normal On-Line mode, press and hold the ON/OFF/Test Button for approximately 4 seconds (four beeps), then release the button. The UPS will perform a ten-second self test. During the self test, the UPS will switch to battery power and the On-Battery LED will blink and the audible alarm will sound. The length of the test that is automati- cally performed every two weeks is longer than the start-up or user invoked test. This test will run for approximately fifteen-seconds to measure the battery’s capability to provide an acceptable amount of runtime. If the UPS fails a self test, one of the LEDs will remain illuminated indicating the type of problem.

Note: The UPS will automatically perform a self test on start-up and every two weeks.

DIP SWITCH SETTINGS

The DIP Switch setting may be changed by the user to set the desired Inverter (on battery) output voltage and the Low voltage transfer set points. The DIP Switches must be set to the desired Inverter output voltage and the Low voltage transfer set points then, the UPS must be turned OFF and restarted to reconfigure the microprocessor and save the changes. The Inverter (on battery) output voltage setting can be either 120VAC (default) or 127VAC. Changing the In- verter output voltage to 127VAC, will also change the Overvoltage set point from 132VAC (default) to 140VAC. The Low voltage transfer set points can be changed to 85VAC (default) or 80VAC or 75VAC.

Inverter output voltage		Low voltage transfer
		Switch	2	3
Switch	1	75V
120V		80V
127V		85V
