Assembly and Instructions for use

10.Functional description
The TSC-UV V2 contains 4 separate network guard loops (CCIF), which are designated KK1,
KK2, KK3 and KK4. non maintainet standby (MB) is triggered when the line of the network
guard loop is interrupted or clumped. The operating status is visualised by the corresponding
LED "KK-ok" as follows:
•LED „KK-ok“ lights up
permanently network guard loop closed
•LED „KK-ok“ flashes
network guard loop triggered
(interruption or fault)
The following must be observed during installation:
•A 10 kΩ terminating resistor must be set.
•The maximum length of the network guard loop must not exceed 500 m.
Voltage drop must be observed.
•cable type J -Y(ST)Y 2x2x0,8mm²
•internal evaluation of the resistance value lies between 5-15kΩ
In the TSC-UV V2, a separate rental power feed (AC local) with integrated network guard is
provided. Here, an additional AC feed can be provided by a local general lighting distributor
and tenant-related electricity billing can be realised.
Only in the event of emergency operation of the main system (non maintenet standby)
by triggering the mains guard loop, battery or test operation or failure of the local general
lighting distributor is switched over to the single-discharger feed of the main plant.
Switching is done by a contactor switch integrated in the MCUV-E.
The network guard function is visualised via the LED "Mains / mains local ok" as follows:
•LED „network / mains
lokal ok“ lights up
Local network ok, power is taken from the local general
lighting distributor
•LED „network / mains
lokal ok“ of
Local mains outside the limit values, power is taken
from the main system
A potential-free relay contact S / S' (NO) is integrated in the TSC-UV V2 for evaluation of the
emergency operation (modified standby by triggering the mains monitor loop (battery or test
operation).
A separate operating mode selector switch (BAS) is provided as a push-button on the TSC-UV
V2 to simplify installation and maintenance work. The BAS can switch off and on the
TSC-UV V2 associated circuits of the DIN rail circuit module (TSM) in continuous light, modified
standby and battery operation off and on.
