Voltage Input Signal
Warning! Read Safety Warning on Page 1
before attempting to use this control.
Note: The Voltage/Current (VLT/CUR) jumper must be in the VLT position (factory setting).
The BC145 is designed to accept a wide range of input voltage signals as follows:
Connect input voltage signal to proper input terminals as
indicated in figure 4.
1.
Connect a 10V DC meter (digital meter is suggested)
to terminals “9” (-) and “10” (+).
2.
Apply the maximum input voltage that would be supplied from tach, transducer, etc.
3.
Adjust the “MAX” trimpot to the desired output voltage.
Example:
A follower motor is to follow the output of a leader motor with an armature volt-
age range of 0 - 90V.
