Buffer modules
Note
Contacts only available for SITOP BUF8600 buffer modules with double-layer capacitors
The control contact "ON", signaling contact "READY" and "BUF" are only available for buffer
modules SITOP BUF8600 with double layer capacitors (SITOP BUF8600 4 s / 40 A and 10 s
/ 40 A).
The buffer mode of the SITOP BUF8600 buffer module with double-layer capacitors can be
prevented using control contact "ON" (terminals "X1" and "X2"), if a scheduled shutdown of
the power supply is planned (e.g. for maintenance, period of no operation, end of work/shift).
This avoids unnecessarily discharging the buffer module.
Deactivation via the control contact is effective for all of the buffer components (buffer
module, UPS module) in the system.
Control contact
Explanation
X1-X2 closed
(delivery state: via wire jumper)
Buffer mode of the buffer module enabled,
System is buffered when the power fails.
X1-X2 open
All of the buffer components in the system deactivated.
The system is not buffered when the power fails.
The signaling contact sufficient buffer readiness "READY" is in the form of a relay contact
(NO contact, terminals "13" and "14"), 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.
For two BUF8600 buffer modules with double-layer capacitors in the system, the threshold
that is set refers to the sum of the charged energy storage devices in both buffer modules.
The signal "Sufficient buffer readiness" refers exclusively to the SITOP BUF8600 buffer
modules with double-layer capacitors.
