E3NW-ECT EtherCAT Digital Sensor Communication Unit Operation Manual (E429)
* The temperature is limited by the number of Amplifiers that are connected.
For 1 to 2 Amplifiers: 0 to 55°C; 3 to 10 Amplifiers: 0 to 50°C; 11 to 16 Amplifiers: 0 to 45°C; 17 to 30 Amplifiers:
0 to 40°C.
The status indicators give the current status of the E3NW-DS.
