7) INSTALATION OF SYSTEM
7.1 Checklist during installation
During installation of the system the following should be checked:
1) The Profibus-DP master should be configured to communicate with the MCE2035 Profibus-DP
module using the supplied GSD file. When configuring with the GSD file a MCE2035 station type
is selected.
2) All hardware connections are made as described below.
3) The load cells are mounted mechanically and connected to the Profibus-DP module using their cor-
responding load cell interface module. The load cell addresses are set using the DIP-switches on
the load cell interface modules, so that they forth running from address 0 (0-3).
4) Using DIP-switches the desired measurement time, filter and scaling is selected.
5) The Profibus-DP module is connected to the Profibus-DP network, and possibly a termination is
made at this Profibus-DP slave.
6) The address of the Profibus-DP module is set using Sw2.2-Sw2.8. Power is applied and the
Profibus-DP communication is started.
7) Verify that the red LED (PBE) on the Profibus-DP module is NOT lit, and that the yellow LEDs
(DES and RTS) are lit/flashing. Verify that the TXBB LED on the Profibus-DP module is lit and
that the TXBB LED’s on the load cell interface modules are also lit (can flash slightly).
8) Verify that the Profibus-DP module has found the correct load cells (LcRegister), and that no load
cell errors are indicated (LcStatus(x)).
9) Verify that every load cell gives a signal (LcSignal(x)) by placing a load directly above each load
cell one after the other (possibly with a known load).
The system is now installed and a zero and fine calibration is made as described earlier.
Finally verify that the weighing system(s) returns a value corresponding to a known actual
load.
Note that in the above checklist no consideration has been made on which functions are
implemented on the Profibus DP master.
