Initial Operation DAC-341
full adjustment
empty adjustment
1. Empty Adjustment
1.1 Level Measuring
• empty vessel completely
• connect ammeter into the current output loop
• the ammeter displays 4,0mA, the internal indicator, AZM displays 0,0%
In this case no adjustment is necessary
• in other case make the adjustment in the following way:
• press button "FF
FF
F" for at least 10 seconds, the indicator shows shortly "Stor",
the setting is done
• ammeter displays 4,0mA, the internal indicator AZM displays 0,0%
1.2 Process Pressure Measuring (relative / absolute)
• set the pressure to the wished value at 4mA
• connect ammeter into the current output loop
• the ammeter displays 4,0mA
in this case no adjustment is necessary
• in other case make the adjustment in the following way:
• press button "FF
FF
F" for at least 10 seconds. The indicator shows shortly "Stor",
the setting is done
• ammeter displays 4,0mA
2. Full Adjustment
2.1 Level Measuring
• fill vessel completely (heigth of vessel at least 25% of full range)
• connect ammeter into the current output loop
• the ammeter displays a value lower than 20 mA, e.g. 14 mA, the internal display AZM
displays a value lower than 100,0
• press button "++
++
+" or "--
--
-", until the ammeter displays 20mA and the internal indicator shows100%
• after about 20 seconds the settings are stored, "Stor" shortly appeares in the display
2.2 Process Pressure Measuring (relativ / absolute)
• set the pressure to high-value (at least 25% of full range)
• connect ammeter into the current output loop
• the ammeter displays 20,0mA, the internal indicator AZM displays the measured pressure
in bar. In this case no adjustment is necessary
• in other case make the adjustment in the following way:
• press button "++
++
+" or "--
--
-", until the ammeter displays 20mA
• after about 20 seconds the settings are stored, "Stor" shortly appeares in the display
3. Offset adjustment
• hold "FF
FF
F" pressed and modify with "++
++
+" or "--
--
-" the standard characteristic parallelly,
in this way offsets are compensated
• the settings are stored after 20s of the last adjustment, the indicator shows "Stor"
This function is needed very rarely.
4. Reset to standard settings
• press buttons "FF
FF
F", "++
++
+" and "--
--
-" togehter about 10 seconds. When the indicator
displays "rES", the standard settings are stored immediately.
Attention: All your settings will be deleted with this function . The pressure sensor
is set to the standard settings.
5. Switching the indicator (%, bar)
• by double-pressing the button "FF
FF
F" you can switch between the indication in bar and %
Connection
• plug in the optional indicator module AZM (helpful for setting)
• apply supply voltage (12...36V DC), see terminal label
• after a short segment test the indicator shows shortly 'dac', the program-version, 'abs' or 'rel' and the presetted range
• level in % (one digit after decimal point) or pressure in bar (two digits after decimal point) is indicated
• note at level measurement: 0-100% means 4-20mA; this range can be adjusted by the user. If the pressure is indicated in bar, the indicator
always shows the pressure measured at the measurement cell. In this kind the range of the indicator can't be adjusted!
Notes to Setting the Pressure Sensor
The standard setting of the DAC-341 is following: 0...100,0% of the measurement range (e.g. 0...400mbar) are corresponding to 4-20mA of the
current output. If it is necessary to change these settings for special measurement tasks, you have to do following:

2. Strip back 1-1/4” of outer sheathing, cut off any excess wires,
shield and ground. Strip off 1/4” insulation from remaining two
wires. It is not necessary or recommended to tin the wires.
1. Insert cable through Pressing Screw, Compression Ring,
Seal Grommet, and Sleeve as shown below.

3. Orient Connector end so that
center pin connecting screw is
horizontal facing right (see detail).
4. Wire LOOP+ (red) wire to top-right
terminal, and LOOP- (black) wire to
top-left terminal. No connection is made
to the center and bottom terminals.
5. Screw on the Sleeve. Hand-tighten only.
6. Press the Seal Grommet into the Sleeve and hand-
tighten the Pressing Screw.
7. Use a wrench to tighten the Pressing Screw another
3/4 turn. Do not over-tighten!
