Baldor BC140 Installation And Operation Manual page 37

To Recalibrate the CL Trimpot:
1. Disconnect the AC power and connect a DC ammeter in series with either motor armature lead.
If only an AC ammeter is available, connect it in series with either AC line input lead.
2. Set the Main Speed Potentiometer to approximately 30% – 50% clockwise position.
3. Set the CL Trimpot fully counterclockwise. The CL LED will illuminate red.
4. Load the motor shaft in accordance with application requirements.
Apply power and rotate the CL Trimpot clockwise until the desired current reading is observed on the DC
ammeter. Factory Current Limit setting is 150% of the full load current rating of the motor. If using an AC
ammeter connected in the AC line input, the factory Current Limit setting will read 75% of the full load
current rating of the motor. Do not exceed 200% of the full load current rating of the motor (maximum
clockwise position).
WARNING! DO NOT LEAVE MOTOR SHAFT LOCKED FOR MORE THAN 2 – 3 SECONDS
OR MOTOR DAMAGE MAY RESULT.
