Remote Setpoint (continued)
"Ext MinSetpoint" and "Ext MaxSetpoint" are found through the following menu path:
Params & Display > LoadController > Configuration
These parameters do not re-scale the input, but provide hard upper and lower limits on
the setpoint. The following is an example on how these parameters may be utilized.
Example: Pressure Sensor Wired to Terminal X61
LC_OptgMode = IntLC X62
Ext Inp X62 U/I = 4..20 mA
MRange PressSens = 200 psi
Desired remote setpoint range = 100-150 psi
A 4-20 mA signal on terminal X62 scales the setpoint from 0-200 psi. Parameters "Ext
MinSetpoint" and "Ext MaxSetpoint" need to be utilized to get the appropriate setpoint range.
With these parameters set, the following input signals will scale the setpoint accordingly:
4 - 12 mA = 100 psi (limited by "Ext MinSetpoint")
12 - 16 mA = 100 - 150 psi
16 - 20 mA = 150 psi (limited by "Ext MaxSetpoint")
