MCS-08AD modules are state-of-the-art strain gauge load cell signal digitizers. These modules are used for
any type of process weighing and force measurement including tank and silo weighing, dynamic weighing,
check weighing, filling, tension /compression force measurement etc.
6.1. Front View
There are 3 status LEDs on the front panel which indicate the operational module status (Refer to table 6.1).
The setup switch on front panel of the module is used for N-bus addressing without PC (Refer to chapter 5.6)
and for diagnostics (Refer to chapter 15).
When the error LED is ON, the other two LED indicate the error type (Refer to chapter 14 for details). Load cell
connection and power supply terminals are located at the front of the DIN rail mount module (See figure 6.1).
