WARNING: If control is wired to a transformer, do not switch the primary side of transformer to disconnect power or catastrophic failure can result. Always disconnect control from secondary side of transformer. CAUTION: Do not bundle potentiometer connections (P1, P2, P3) and Inhibit™ connections (I1, I2) with AC line or motor wires. WARNING: Armature Switching. - Page 6 Note: The MIN speed adjustment will affect the MAX speed setting. Therefore, it is necessary to readjust the MAX speed after the MIN speed, and it may be necessary to repeat the sequence until both the MIN and the MAX speeds are set to the desired levels.
- Page 7 FIG. 5B – DYNAMIC BRAKE CIRCUIT (Using Inhibit™) Notes (Dynamic Brake Circuit) * Choose RB resistance and wattage according to braking requirements. ** Inhibit™ circuit extinguishes output of control during brake. When the armature is reenergized, the Inhibit™ releases which allows for a smooth start. C.
