20 ER3000 User Manual
Figure 8 shows how to provide a 0-5V signal to the analog setpoint from a
potentiometer. The 0-1V range can be programmed to be a failsafe condition for
1-5V ER3000’s. Refer to section 5.4, Failsafe Limits, for more information on
failsafe.
Note: The ER3000 cannot directly provide a 0-10 volt signal. An external 10-
volt supply must be used for power.

NOTE: Wire power as shown in figures 2 & 3
Figure 9 shows how to provide the analog setpoint from an active variable
current supply.

Figure 9 also can represent how to provide a 1-5V/0-10V analog setpoint. The
negative lead (-) of your source connects to the red wire and the positive lead (+)
connects to the brown wire.
