Executing a RESET

4.6.1

Software RESET ("warm start")

Software RESET

If the MA 30/31 (or the BCL xx connected to the MA 30) does not respond
even though operating voltage is being applied and the RDY LED does not
illuminate, you should first carry out a software RESET. Press the "Reset"
button on the MA 30/31 for

longer than 0.2 and shorter than 4.0s

. The

operating software will be restarted and the devices with the current param-
eters newly initialised. Following initialisation, the master responds with "00S"
and the RDY LED must illuminate.

If the MA 30/31 does not respond even after carrying out a warm start, there
may be an error in the setup settings, i.e. the "current parameter set" of the
MA 30/31. A hardware RESET (see chapter 4.6.2) returns the parameter set
to a defined state so that the units are again operable.

4.6.2

Hardware RESET ("cold start")

Hardware RESET

With a cold start, you can either return the MA 30/31 devices (and the BCL xx
connected to the MA 30) to the factory settings (factory parameter set) or to
your customer-specific parameter set

1

. Which parameter set is loaded

depends on the position of the

DIP switch 2

. Initiate a cold start by pressing

the RESET button for

more than 4s

.

Attention!

A cold start replaces the current parameter set either with your customer-spe-
cific parameter set or the Leuze factory parameter set, i.e. any settings made
there are lost. Therefore, perform a hardware RESET only when the software
cannot be started or when you intentionally want to reset the MA 30/31 (and
the BCL xx connected to the MA 30).

Figure 4.6: Loadable parameter sets during cold start

1. A customer-specific parameter set can be created using the software command

"pc01" to store a current, valid parameter set as the customer-specific parameter set
in the MA 30/31. Correct storage is acknowledged by "ps0".
