Setting range: 0 s…180 min
Resolution of settings: 50 ms / 100 ms / 1 s / 5 s / 1 min
4. t(test) Test time for "Autom. changeover":
Setting range: 2 s…180 min
Resolution of settings: 1 s / 5 s / 1 min
5. System U1-U2 Voltage line 1 - Voltage line 2
Line G Line 1 - Generator
L1-L2 Line 1 - Line 2
AV-SV Normal power supply source - Safety power supply source
SV-AV Safety power supply source - Normal power supply source
SV-UPS Safety power supply source - Special safety power supply source
UPS-SV Special safety power supply source - Safety power supply source
SV-BSV Safety power supply source - Battery-supported safety power
supply
BSV-SV Battery-supported safety power supply - Safety power supply
The setting also influences the creation of the alarm text which is displayed in case of
voltage failure on a line:
Setting alarm text
U1-U2 Undervoltage, overvoltage, voltage value
Line G, L1-L2 Failure line 1, failure line 2
AV-SV, SV-AV Fail.norm.supply, Fail.safet.supply
SV-UPS, UPS-SV Fail.safet.supply, Failure UPS
SV-BSV, BSV-SV Fail.safet.supply, Failure BSV
Explanation of abbreviations:
AV = Normal power supply source
SV = Safety power supply source
UPS = Special safety power supply source
BSV = Battery-supported safety power supply
6. SwitchBackLock on Switch-back lock enabled
off Switch-back lock disabled
See chapter „Time diagram: Changeover between preferred and redundant line“ on p.
19.
7. Preferred line 1 Line 1
2 Line 2
In generator mode, line 1 is always the preferred line.

note: A parameter change can result in an immediate changeover.
8. Test interval Interval for testing the changeover function:
Setting range: off, 1…24 months
Resolution of setting: 1 month
