WARNING! If Signal Isolator is connected to multiple speed controls;
1) Multiple controls must be powered from the same phase of AC line.
2) The positive input terminal to each speed control must be installed with a 1 amp, 600V (1N4005) isolation diode
as shown.
3) Multiple speed controls can not be used with PWM, Regenerative or Variable Frequency Drives (Inverters).
B) From a Single Main Potentiometer
A 10K ratio poten-
tiometer is used to
control up to ten
(10) follower motors.
If a 5K ratio poten-
tiometer is used, up
to five (5) follower
motors can be con-
trolled.
