There are following fuses on the printed circuit board of the power supplies:
Power supply
Fuse
Type
Voltage rated value
SP22.5/SP23.5
F601
T4A H
250 V
SP8.5
F400
T8A H
250 V
NOTE
The power supply PC boards are suitable for the connection to IT
systems.
2.2.2 Voltage monitoring functions
The input voltage is monitored for undervoltage and overvoltage conditions.
Input voltage
Response
Undervoltage:
SRx.1/SRx.2:
< 20 V
or
SRx.3/SRx.4:
< 170 ...175 V
Green OK-LED goes dark
The output voltages are shutdown;
CPU stop (DSAVE signal)
The system automatically restarts when
the input voltage increases to approx.
196 V.
Overvoltage
SRx.1/SRx.2:
> 32 V
or
SRx.3/SRx.4:
> approx. 265 V
Red fault LED is lit;
The output voltages are shutdown,
CPU stop (DSAVE signal)
Automatic restart
All of the output voltages are monitored for an undervoltage condition (e.g.
as a result of overload/short-circuit)
Undervoltages at the output
Response
V (5 V)
< 4.7 ... 4.85 V
(for t>100-200 µs)
Red fault LED is lit
The output voltages are shut down;
(CPU stop)
No automatic restart (the line supply
voltage must be disconnected)
V (+ 15 V)
< approx. 14 V
V (- 15 V)
> approx. -14 V
Red fault is lit
5V voltage remains
System failure message
The associated module (under the „STOP“ tab) is configured in HWConfig
under "object properties" to define how the module behaves when a system
failure message is output (bus signal *RDYIN=low):
Modules can reset their binary and analog outputs
CPU modules can go into the "stop" condition ("H")
