Remote Setpoint (continued)
Pressure Sensor Wired to Terminal X61
When operating on pressure, a 20 mA signal translates to the value programmed into
parameter “MRange PressSens”. Parameter
“MRange PressSens” can be accessed
through the following menu path:
Params & Display > LoadController > Configuration > MRange PressSens
This value should not be changed as it is used to scale the high end of the pressure
sensor connected to terminal X61. This should simply be noted for later calculations.
Temperature Sensor Wired to Terminal X60
When operating on temperature via an RTD wired on terminal X60, a 20 mA signal
translates to the value programmed
into parameter “MeasureRangePtNi”. This
parameter can be set for 302°F, 752°F, or 1562°F. It is recommended for best resolution
that this is set to 302°F unless a setpoint over 302°F is desired. Note that if
“MeasureRangePtNi” is exceeded, a temperature sensor fault will occur. Parameter
“MesaureRangePtNi” can be accessed through the following menu path:
Params & Display > LoadController > Configuration > MeasureRangePtNi
Temperature Transmitter Wired to Terminal X61
When operating on temperature via an analog input on terminal X61, a 20 mA signal
translates to the value programmed
into parameter “MRange TempSens”. Parameter
“MRange TempSens” can be accessed through the following menu path:
Params & Display > LoadController > Configuration > MRange TempSens
This value should not be changed as it is used to scale the high end of the temperature
sensor connected to terminal X61. This should simply be noted for later calculations.
5. Finally, upper and lower setpoint limits can be programmed using parameters “Ext
MinSetpoint” and “Ext MaxSetpoint”. These parameters are percentages of the range
from the low setpoint limit to the high setpoint limit. As a formula, these parameters
should be set using the following method:
