Automatic load sharing system for the drawworks, rotary table and mud pump motors SCR firing circuits with ‘hard firing pulse’ output Gate suppression at approximately 150% of the highest single motor current limit
All controls are designed to be ‘fool-proof’Individual control of current limits for all drilling functions Zero throttle interlock
