MBUS-PS - User manual
The reception LED begins to light up sporadically.
Only trained and appropriately qualified personnel are allowed to check the electric power supply (see
Section 1.2.3).
Check the cable between MBUS-PS and the meter, and replace faulty cables if necessary. Disturbances may
be present on the M-Bus and be interpreted like received data. The reception LED should be reset at the next
reading (request from the master, sending from the slaves).
If errors could not be eliminated and if all logical settings are correct, please contact our customer support:

The collision LED is blinking regularly without communication.
Only trained and appropriately qualified personnel are allowed to check the electric power supply (see
Section 1.2.3).
The devices MBUS-PS125, MBUS-PS250 and MBUS-PS500 detect an overload if the maximum number of
connected unit loads is surpassed. This is indicated by a regularly blinking collision LED. A reception of data
is no longer possible then.
Check the M-Bus installation. How many meters are connected? Reduce the number of meters, if possible.
Is the current consumption of the M-Bus proportionate to the number of connected slaves?

The collision LED lights up when sending respectively when receiving.
Only trained and appropriately qualified personnel are allowed to check the electric power supply (see
Section 1.2.3).
Check the M-Bus installation. How many meters are connected? Reduce the number of meters, if possible.
Do several meters have identical bus addresses? What is the overall capacity of the bus? Replace the faulty
cable if necessary or parameterise the meters correctly.
In case of a high capacity on the bus (e.g. long cables, many meters) the data transmission remains
undisturbed even though the collision LED lights up; this can be ignored.
If errors could not be eliminated, please contact our customer support:
