WIKA operating instructions digital indicator model DI35-M 37
The inital and final value is always displayed without comma. The
demonstration of the measuring value in the display is taken as base, so with
a demonstration of e.g. 6.400 the final value can be parameterized by 6400
on this display value.
PN34: Interface behavior
The current display value can be sent by the optional interface. In standard
mode PN34 = 0 the display stays passive and expects data from the bus.
This operation is used for the configuration of the display. For slower actions
the instantaneous measuring value can be actively asked for by command. In
sending mode PN34 = 1 the displays sends actively in cycle of the measuring
time the current measuring value. For further information please see chapter
„6.3.7 Serial Interface RS232/ RS485“.
PN50 to PN52: Security setting , user level
With the parameters in the security settings, access to the program numbers
is regulated through the setting of various user levels. The user levels divide
the access into various levels. The user is only given access to the settings
authorized by the system operator, such as the setting of thresholds. The
lower the figure for the user level given under PN52, the lower the level of
security of the unit parameters against user intervention .

The user level 1,3, and 5 are reserved. With rising userlevel, the number of
for the user unlocked parameters decreases, according to the above shown
table.
The parameterized user level PN52 is active as long as the authorization
code PN51 and programming lock PN50 are different. On delivery both
parameters are set to 0000, so that the programming lock is deactivated.
