To activate the set user level, you must enter a four-digit number under PN51
as a "locking code" and confirm it by pressing the [P] key for approx. 1
second.
On changing to programming mode, the unit jumps to the first authorized
program number. If user level PN52 = 3, then, for example, the parameters of
the set points can be changed, but changing the parameter of the measuring
input (PN0) is not possible at this user level.
In order to obtain access to all program numbers later (equivalent to user
level 0), you have to enter under PN50 the same code you used before under
PN51. You must then acknowledge this by pressing the [P] key for approx. 1
second. After this you have access to all program numbers.
Information
If the authorization code becomes lost, the unit can be set to
the default value 0000 at the manufacturer's without any data
loss.
PN59 to PN97: Setpoints / Relays
You can influence the behavior of the setpoints with various program
numbers. The figures refer to the scaled measurement and are updated with
the set measuring time. A description of the various parameters is given in
chapter „6.3.4 Description of the alarm outputs”.
PN100 to PN130: Linearization
Through the linearization, the user has the possibility to linearize a non-linear
sensor signal. A detailed description can be found in chapter „6.5 Description
of the measuring input“, part „Linearization“
PN100 ≥ 0.
PN180: Totalizer / summation function
For the add of measuring values, 3 operation types are available:
PN180 = Activator for MIN/MAX value reset
0 Without summation function, the sum value is pre-allocated with
„0“ and does not change any more.
1 Without permanent storage e.g. for dose procedures < 30 min
the sum value is not stored in the devices memory, it could be
damaged by being set back too often. In case of power failure
all data get lost.
2 Permanent storage e.g. for the survey of quantities or distances
or for longer spaces of time > 1h. Here a data loss in case of a
power failure is avoided.
