Example (decimal):
STATUS= „5” means UPS_SB_OUTPUT_ACT (4) + UPS_SB_BYPASS_MODE (1) are active
! = UPS on Bypass!
STATUS= „12” means UPS_SB_OUTPUT_ACT (4) + UPS_SB_BACKUP_MODE (8) are
active ! = UPS Powerfail!
STATUS= „22” means UPS_SB_OUTPUT_ACT (4) + UPS_SB_BACKUP_MODE (8) +
UPS_SB_BATTERY_LOW (10) are active ! = UPS Powerfail and Battery low!
STATUS= „4” means UPS_SB_OUTPUT_ACT (4) + no other alarms = UPS OK
D.7. Bus termination
It is necessary to set the last bus device on the RS-485 Bus jumper for the bus termination.
(120 Ohm) The jumper is already set in newly delivered adapters. Please remove the 4 screws
at the underside of the adapter in order to open the box. You will find the jumper J1 near the
network connector, near the PCB shows a “+” symbol. (see fig.) Default is OFF = CS121 is
NOT last device. To terminate the RS485 bus at your CS121, please close the Jumper.
