Lifetime indicators (service life)
The LEDs indicate the remaining service life of the device.
It is based on the sum of all loads. The service life starts at
15 years and decreases depending on the stress level and
the load.
Load level indicator (load level)
The LEDs indicate the current load of the device without
any delay:
Display elements
Stress level indicator (Voltage level)
The green, yellow and red LEDs indicate the electrical and
thermal load. This data is collected and evaluated during a
three-hour cycle. The operator is thereby able to check
and then modify the ambient conditions to prevent nega-
tive influences on the device.
Installation (continued)
Internal fuse
The internal input fuse protects the device and cannot be
replaced. If an internal fault occurs, return the device to the
manufacturer as a precautionary measure.
Rail mounting
Provide sufficient ventilation and cooling. Do not obstruct
the ventilation holes.
►
Slightly tip the device to the rear.
►
Affix the device to the upper edge of the rail.
►
Slide down until it stops.
►
To latch, press on the lower front side.
►
Shake the device gently to verify that it has been
latched.
Removal
►
Switch off the power supply and disconnect the sys-
tem from mains. Disconnect all connectors from the
power supply.
►
Slide the latch guard down (unlatch).
►
Slightly raise the front edge of the device (tip) and
remove.
Symbol
Meaning
Green
Low pulse speed: everything OK, a long
service life can be expected.
Yellow
Pulse speed increasing: thermal load not
optimum. No immediate risk of overheating.
Slightly accelerated aging. Reduce the load
or improve ventilation!
Red
High pulse speed: poor internal
thermal state, service life at serious risk.
Check the load and improve ventilation!
Symbol
Meaning
Green
Power supply with long service life
Yellow
Service life less than 3 years, replace during
next maintenance cycle
Red
Power supply at end of service life, replace
immediately
Symbol
Meaning
Green
0...80% load
Yellow
81...100% load
Red
>100...150% load, typically when a higher
current is required, max. 4 s
Indicator elements (continued)
Error indicator
As soon as the output voltage lies outside of
the working range 22...28 V DC (e.g., short
circuit), only the load level indicator illuminates
red. The other two indicators are switched off.
Operating elements
Potentiometer
Used for setting the output voltage.
