Image 4-13 Connection of load cell METTLER TOLEDO type WM, WMH to RS 485
Connecting METTLER TOLEDO type WM or WMH some additional parameters must be set.
See 5.2.31
4.5.11 RS 485 interface for load cells made by Wipotec/Kaiserslautern
Type EC and IW digital load cells from Wipotec can be connected to the Siwarex.
This enables the realization of quick check-weighers.
The following interface parameters must be set in datasets 3 and 7:
(DR3) load cell type: Wipotec
(DR7) RS485 baud rate: 38400 Bit/s
(DR7) RS485 character parity: odd
(DR7) RS485 data bits: 8
(DR7) RS485 stop bits: 1
Terminal Signal name Remarks
X1.19 24 V Voltage supply
X1.20 0 V Voltage supply
X1.21 485a Input Ta
X1.22 485b Input Tb
