Voltage Produced by the 4–20 mA External Feedback
Figure 36 shows correct wiring for applications where it is
necessary to monitor the voltage produced across the ER5000’s
internal 250Ω resistor, rather than breaking into the 4–20 mA
loop, to avoid producing ground loops.

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.
The feedback signal can, alternatively, be monitored
through the USB connection between the ER5000 and the
PC by reading variable #44 (ID_FEEDBACK).
Refer to Table 19 for correct wiring.
