• After the operating voltage and the signal lines have been connected, zero or offset must first be
adjusted. No signal may be present at input (I
• The analog output must correspond to a preselected output signal from table 6.3.5. Any inaccuracy can
be adjusted with the ZERO potentiometer.
• To adjust the measuring upper range (full scale) value, a current of pre-
ferably the strength of the upper range value should be given. If this is
not possible, one of the following adjustment equations should be
used:
Example: The current transducer is to be set to the following values:
Input measuring range:
Output measuring range:
Constant current for configuration
The output current calculated must be adjusted with the SPAN potentiometer to I
When the voltage output is used, the same adjustment procedure is necessary.
4.3.7.2. Threshold value output
A current that corresponds to the threshold value is to be given for the module.
The TIME potentiometer must be set to "0 s" and the threshold value (SW) potentiometer is to be turned
according to the following adjustment ruling (following Fig 4, page 22):
• Fig. 1: The threshold value (SW) potentiometer must be turned until the SW-LED lights up.
• Fig. 2: The threshold value (SW) potentiometer must be turned until the SW-LED goes off.
• Fig. 3: The threshold value (SW) potentiometer must be turned until the SW-LED goes off.
• Fig. 4: The threshold value (SW) potentiometer must be turned until the SW-LED lights up.
In order to avoid switching actions at the binary output level during a brief overload, a suppression time
must be set with the TIME potentiometer. If an increased current is present for longer than the given
suppression time, the preselected switching behavior becomes active. The possible adjustment range is
between 0 and 20 seconds.
When the yellow threshold value (SW) LED lights up (relay and transistor status display) the N/O contact
of the PDT contact is closed and the N/C contact of the PDT contact is open. The transistor output
switches through.
4.4. Software package (adapter)
As an alternative to setting via DIP switch, programming is possible using MCR/PI-CONF-WIN, the
configuration software (Order No. 2814799).
The software offers the following:
• Entering all the configuration parameters in the computer
• Saving the parameters entered in the computer in the measuring transducer
• Exporting the parameters available from the module
• Saving parameters in a drive of your choice
• Creating a side-panel label
• Printing the programmed module parameters
• Bar graph display
• Monitoring function
• Input of user characteristic curves possible
The software runs under Windows 95™, 98™, ME™, NT™, 2000™ and XP™.
Interface converter MCR-TTL/RS232-E (Order No. 2814388) serves to connect the computer and
the current measuring transducer. This converter has a stereo jack plug on one side for connection
to the current measuring transducer and a 25-pos. SUB-D socket on the other side for connection
to a computer. On the computer side, the interface converter must generally be connected with a
cable adapter (25 to 9-pos. SUB-D plug connection, Order No. 2761295).
