I thank all of You that have offered some advice, & I don't have the model # of the motor, but it was a 90V dc, permanent mag motor. Th model number for the control is exactly as John Crighton guessed Leeson # 174308, but Alan, the braking device is built into the control, & there isn't any thing else at the motor location.
The distance to the motor is about 200 ft.
The Farm Owner had installed NMB to serve the motor, but it looks to be OK.
As far as setting the control, I couldn't get the motor to slow with the individual adjustments at all.
I didn't keep the manual, but if I remember correctly,
You are supposed to set the POT to 100%, then slowly increase the speed control setting until you reach the max speed You need.
I couldn't slow the motor with the speed setting, or the potentiometer ? It was almost like the control wasn't effecting the motor at all.
Also, even with the motor stopped, reversing it causes the 20 amp SP breaker to trip ? Before, & after the control was changed.
I have thought about running a temp wire out to the motor, just to bypass the existing wiring.
Thanks again !
