Dip switch info

Bit Switch Option when bit=1

0 4 Low battery alarm changed from 2 to 5 mins. Autostartup

disabled on SU370ci and 400

1 3 Audible alarm delayed 30 seconds

2 2 Output transfer set to 115 VAC (from 120 VAC) or to 240

VAC (from 230 VAC)

3 1 UPS desensitized - input voltage range expanded

4-7 - Unused at this time

Status bits

This is probably the most important register of the UPS, which indicates

the overall UPS status. Some common things you’ll see:

• 08 = On line, battery OK

• 10 = On battery, battery OK

• 50 = On battery, battery low

• SM = Status bit is still not available (retry reading)

Bit Hex

Bit

Meaning

0 0x01 1 = Runtime calibration occurring Not reported by Smart

UPS v/s and BackUPS Pro

1 0x02 1 = SmartTrim Not reported by 1st and 2nd generation Smar-

tUPS models

2 0x04 1 = SmartBoost

3 0x08 1 = On line (this is the normal condition)

4 0x10 1 = On battery

5 0x20 1 = Overloaded output

6 0x40 1 = Battery low

7 0x80 1 = Replace battery
