13.2 Description of signaling
In contrast to the default signaling set upon delivery, you can
customize the signaling to the specific needs of the system.
The following signal options can be selected to signal
system states.
13.2.1 Output voltage
Signals whether the output voltage is in the preset range. If
the output voltage of the power supply falls below the set
threshold value, the signal state changes.
Example of use
Indicates whether connected loads are being supplied.
Used to quickly detect a load circuit that is not being
supplied (e.g.,in the event of mains failure or short circuit in
the supply line).
13.2.2 Output current
If the output current of the power supply exceeds the set
threshold value, the signal state changes.
Example of use
In the case of system extensions, loads are added. This
increases the utilization of the power supply. Preventive
function monitoring detects critical operating states in good
time. Action can be taken before system downtime occurs.
13.2.3 Output power
If the output power of the power supply exceeds the set
threshold value, the signal state changes.
Example of use
In the case of system extensions, loads are added. This
increases the utilization of the power supply. Preventive
function monitoring detects critical operating states in good
time. Appropriate measures can be taken before system
downtime can occur.
13.2.4 Operating hours
If the preset operating time of the power supply is exceeded,
the signal state changes.
Example of use
For systems with a very long operating time, suchas wind
turbine generators or refineries, maintenance intervals are
planned. You can even schedule the maintenance date
during configuration based on the ambient temperature and
utilization of the power supply (see service life section).
13.2.5 Early warning of high temperature
Before the power supply protects itself through power
derating in the event of an overtemperature, the signal state
changes.
Example of use
Outdoor control cabinets can reach a high internal
temperature depending on the position of the sun. The same
is true if a control cabinet fan or cooling system fails. In the
event of any form of overtemperature, the power supply
provides a warning by means of this signal, well before the
supply of the loads is in any danger.
13.2.6 Voltage limitation active
If the circuit inside the device for protecting against surge
voltages is activated at the output, the signal state changes.
Example of use
Normative requirements stipulate that an upper voltage limit
must be observed at the output in the event of an error. It
must therefore be ensured, forexample, that safety-related
controllers are not supplied with an output voltage that
exceeds 32VDC, even in the event of an error. If foreign
bodies (ferrules, screws, etc.) enter the power supply and
generate an error, the signal state changes.
The simultaneous control of multiple signal
outputs by means of one signal option is
possible, as is the use of logic operations to
link multiple signal options to one control. The
power supply is configured using the QUINT
POWER software or the QUINT POWER app.
