Automatic switch-on
can be activated in the factory if the
UH50
is not supplied with the
battery connected (e.g. if powered through a power supply unit). On subsequent start-up, the
date and time are not defined. In this case, the
UH50
enters the input menu when the power
supply is connected.
Entry of the date
Entry of the time
Return to normal mode (manual)
The LCD button 1 can be used to call the menu lines one after the other.
Entry
of the date and
time is described under
Parameter setting menu
.
On (manual) return to normal mode, automatic switch-on is permanently deactivated, even if the
date or time has not been entered!
If no entry is made, the
UH50
automatcical returns to normal mode after no more than 15 hours
*)
and automatic switch-on remains active. The next time the power supply is connected or on
power recovery, the input menu will be displayed again.
Note: Automatic switch-on is
only active if the calibration seal is set
!
*)
Attention: Currently there is a deviant behaviour.
“The automatical quitting of the menu after 15 hours does not work. The user must be informed
that it is essential to leave the menu manually. Otherwise the meter will not count any values.”
Note: In firmware 5.06 an higher this error is removed.
The UH50 can output the data part of the response telegram (according to EN62056-21 Mode
B) with an increased
baudrate
. The 5th character of the ID telegram (“/LUG
x
UH50”)
corresponds to the code for the increased baudrate.
Code Baudrate
C 2400
baud
D 4800
baud
E 9600
baud
F 19200
baud
After the ID telegram, the data part is transmitted with this increased baudrate.
The parameter for the high baudrate value is set by telegram in calibration mode (Eb), test
mode (Pb) or or normal mode (Nb).
It is also possible to parameterize whether the increased baudrate will apply to all data traffic or
just to the next telegram.
Calibration mode
(“Eb”) can be called after opening the cover with the calibration button (=
short-circuiting of two pads for 3 s; operated with a service tool).
Calibration mode
As long as the calibration seal is not set, calibration mode can also be called by telegram via the
optical interface.
Calling calibration mode using the pads automatically resets a set
calibration seal
!
Return to normal mode is performed
−
By telegram, e.g. via PappaWin
−
By pressing a button (LCD button 1 or 2)
−
Automatically no more than 15 hours later.
The
calibration seal
prevents subsequent changing of protected unit parameters that are
relevant for measurement. For example, calling calibration mode by telegram is blocked.
Setting the calibration seal terminates any
simulation
that may be in progress (flowrate or
temperature). Exception: “
Permanent return simulation
”.
After the calibration seal has been set and a volume of 10 liters has then flowed through, the
accumulated
missing time
is set to zero.
