4–20 mA External Feedback, Ground Referenced Input,
Feedback Signal Monitored by PC or PLC A/D Card
Figure 35 show how the feedback signal can be monitored
using an A/D card in the PC or a PLC. The feedback signal can,
alternatively, be monitored through the USB connection between
the ER5000 and the PC by reading variable #44 (ID_FEEDBACK).

WARNING
The controller must be disconnected from the power supply before
any additional wiring or change to jumper configuration is
performed. Do not reconnect the power supply until all additional
wiring connections have been made and are properly installed.
Refer to Table 18 to verify correct wiring.
