Description of the Functions
Equipment Supplied
– Converter YDA 01 Z
– Power cord
– Standard cable “MP8” for connecting MP7, MP7-2
or MP8 balances/scales to YDA 01 Z
– V 24 cable for connecting MC1 balances/scales
to YDA 01 Z
Description of the Functions
Digital/analog converter YDA 01 Z is designed to
convert digital signals into analog voltages or loop
currents. Such an analog signal is available with two
different voltages and three different loop currents
at a 5-in round socket (similar to a DIN stereo jack).
The lower rating of the two voltages ranges from
+1 volt to –1 V.
The higher voltage ranges from +10 V to –10 volts.
The current interface can be adjusted to the following
loop currents:
a) 4– 20 mA
b) 0– 10 mA
c) 0– 20 mA
Setting a) complies with ISA S50.1, Standard
Class U, with the following specifications:
Load resistance: 300– 800 Ω
Supply voltage: 23– 30 V
Internal resistance: 600 Ω
Intrinsic safety: 250 Ω
6

Digital input signals can be supplied to the converter via
the V24/RS 232 interface.
The converter enables the following devices to be
connected to analog processing systems (such as a Y/t
recorder):
a) Sartorius balance/scale with an MP7, MP7-2
or MP8 microprocessor
b) Sartonet bus
c) Device with a V24/RS 232 interface
It converts each digital value comprising 3 decades into
analog voltage or loop current.
The position of these 3 decades can be selected in a
range of 8 decades maximum.
The 3 particular decades selected are then indicated by
the corresponding LEDs on the control panel.
In addition, the converter will provide one of the
following reference voltages when you press the
appropriate pushbutton:
a) +1 volt and +10 volts (+ pushbutton)
b) –1 volt and –10 volts (– pushbutton)
c) 0 volts (0 pushbutton)

Converter Settings
Adjusting the Operating Voltage
Rear view of the converter:
The small arrow points to the actual setting of the voltage selector.
The operating voltage has been factory-set to 220 V.
How to change the voltage setting:
Adjust the voltage selector (1) to your local line voltage. Write the new voltage setting on the
manufacturer’s label on the rear panel of the converter. Whenever you change the operating
voltage to 100/120 V, make sure to exchange the T 80 mA fuse (1) for the T 160 mA fuse
that comes with the converter.
This fuse, along with the voltage selector, is plugged into the rear panel
of the converter.
100/120 V – T 160 mA
220/240 V – T 80 mA
At the point of use, plug the power cord into a properly installed wall outlet.
If you use a wall outlet that does not have a protective grounding conductor, make sure to
ground the balance.

Settings on the Front Panel of the Converter
Front view of the converter:
Description of the pushbuttons:
“0” pushbutton: When you push this button, a reference voltage of 0 is generated at
pins 1 and 3 of the 5-pin round socket.
“+” pushbutton: Press this button to have a reference voltage of +10 volts generated
at pin 1 and +1 volt at pin 3 of the 5-pin round socket.
“–” pushbutton: Press this button to have a reference voltage of –10 volts generated
at pin 1 and –1 volt at pin 3 of the 5-pin round socket.
“DISPLAy” Push this button to initiate selection of the decade range.
pushbutton: The decade range consists of 3 decades which can be shifted
anywhere within the converter’s maximum range of 8 decades.
Once the “DISPLAY” pushbutton is pressed, the LEDs will
flash for about 3 seconds. If you press the “+” or “–” pushbutton
during this time, the next higher or lower decade level will be
automatically selected each second. To terminate the selection
procedure, release the “+” or “–” button.
The decade range selected is read into a non-volatile
memory so that it will remained stored no matter if you switch off the
converter.
“RESET” button: Press this button to have the YDA 01 Z converter enter
the “POWER ON” operating state (corresponds to the power
up routine).
