"READY" signaling contact
Using control contact "ON" (terminals "X1" and "X2",
â‘ ), the buffer mode of the UPS
module can be deactivated if the power supply (line voltage) is scheduled to be shut down
(e.g. maintenance, pause, end of work/end of shift). This avoids unnecessarily discharging
the battery module.
Deactivation via the control contact is effective for all of the buffer components in the system.
X1-X2 closed
< 10 Ω
(Delivery state: via wire jumper)
Buffer mode of the UPS module enabled.
System is buffered when the power fails.
X1-X2 open
> 1 MΩ
All of the buffer components in the system deactivated.
The system is not buffered when the power fails.
Using control contact "START" (terminals "X3" and "X4", â‘¡), when the power supply voltage
(line voltage) is missing, the power supply system can be started using the energy saved in
the battery module (island operation).
Control contact START â‘¡
X3-X4 closed
The power supply system is started from the battery module.
X1-X2 open
> 1 MΩ
Starting from the battery module deactivated.
The signaling contact sufficient buffer readiness "READY" is in the form of a relay contact
(NO contact, terminals "13" and "14",
â‘¢) - and signals that the buffer module is charged to x
% (factory setting: 85 %) and is therefore ready for buffering. The threshold value can be
freely parameterized via the Industrial Ethernet/PROFINET interface.
