Master Mode - Analog Feedback
The MLP-Trim can be scaled for Engineering Unit setpoint entry and Tach display
operation using the analog input for the feedback signal. The following Control
Parameters give the MLP-Trim the necessary information for analog feedback operation
in Master mode.
Analog Input Allocation (CP-84)
Setting CP-84, Analog Input Allocation, to a value of "2" allocates the
analog input to be used as the feedback source.
Master Engineering Units (CP-20)
The actual value of the Master Engineering Units if the system were to
operate with an analog feedback level of 10.0 volts. This is the maxi-
mum calibrated analog input level (refer to Installation/Setup: Calibra-
tion, Analog Input Calibration).
Note: The analog input does not need to operate to 10.0 volts full scale to be
used for analog feedback.
