Also we can use addresses 127 to get the UPS status. A decimal value will be received from address 127.
If that value is converted to binary number, the UPS status can be read.
Online Mode
ESD interface is activated
DC Bus voltage is out of limits
General Alarm
Example:
Let’s receive 28673 (DEC) from address 127. If that value is converted to binary number,
111000000000001 will be obtained. Then the following status can be read from that number:
bit 0
UPS operates on Online Mode
bit 1
UPS operates on Bypass Mode
bit 2
UPS operates on Battery Mode
bit 3
Output voltage is out of limits
bit 4
Output overload
bit 5
Inverter temperature is high
bit 6
Rec
tifier t
emperature is high
bit 7
Ambient temperature is high
bit 8
Bypass is not synchronized
bit 9
Maintenance Bypass Breaker is “ON”
bit 10
UPS operates on Green Mode
bit 11
Battery Failure
bit 12
ESD interface is activated
bit 13
DC Bus voltage is out of limits
bit 14
