  • Page 3: Introduction

    1 INTRODUCTION Thank you for purchasing this O.S. Walker Chuck Control. If used and maintained properly, it should serve you for many years. However, if installed and used improperly, it can be rendered inefficient and unsafe. Therefore, it is absolutely essential that anyone who uses this control or is responsible for its application be trained on how to use it correctly.
  • Page 4: Safety Instructions

    2 SAFETY INSTRUCTIONS 2.1 General Safety Rules Following these simple rules can help to avoid accidents: • Never attempt to operate this control and your magnetic chuck until you read and understand this operator’s manual. • Never disconnect a magnetic chuck from the control’s DC power source while it is energized! Electrical arcing will occur and may cause serious injury or death.
  • Page 5: Recognize Safety Information

    2.2 Recognize Safety Information This is the safety alert symbol. When you see this symbol on your magnet or in this manual, be alert to the potential for personal injury. Follow recommended precautions and safe operating practices at all times. This indicates a situation in which a hazard is imminent and will result in a high probability of serious injury or death.
  • Page 6: Additional Warnings

    2.3 Additional Warnings • Disassembly or repair of this chuck control can result in reduced holding power and/or cause an unsafe condition. Therefore, any time the control is disassembled or repaired it should be thoroughly inspected and re-tested for proper electrical grounding and power output. • Modification of any operating circuits and electrical safety grounding can reduce the chuck control’s effectiveness and/or cause an unsafe condition.
  • Page 7: Mounting The Chuck Control & Connecting Electrical Power

    3 INSTALLATION All electrical chassis must be safety grounded. • Check that all sources of power are disconnected, locked out and tagged “Out of Service” prior to beginning • installation. Only qualified personnel should install this chuck control unit. • Prior to beginning, thoroughly plan your installation.
  • Page 8: Connecting The Chuck

    3.1.3 Connecting the Chuck The DC output to the chuck must include a ground wire that is connected to the safety ground lug on the chuck and to the chassis of the chuck control. It is recommended that the conduit for the DC output not be routed near high voltage AC wires.
  • Page 9: Connecting Optional Features

    3.1.7 Connecting Optional Features SMART-D chuck controls are equipped with three optional features, Current Sensing, Part Release and Lockout. These features enable the chuck control to work with external equipment such as machine controls or a PLC. Refer to the “Operation” section 4 of this manual for using of these features. 3.1.8 Current Sensing This control is equipped with a current sensing feature that monitors the current flowing to the chuck and indicates when this current has reached a predetermined value.
  • Page 10: Operating Instructions

    2. When any control (power section) is to be placed in a secondary enclosure while still in its original enclosure, the following specifications must be met: a. With the control (power section) mounted in its original enclosure and then mounted in a secondary enclosure, the air surrounding the original enclosure should not exceed 104°...
  • Page 11: Workpiece Material

    4.1.4 Workpiece Material Low carbon steel such as SAE 1020 steel, are nearly as good conductors of magnetic lines of force as pure iron. However, many other alloys contain non-magnetic materials which reduce the ability of magnetic lines of force to flow. An alloy such as SAE 300 series stainless steel is almost as poor a conductor of magnetic lines of force as air.
  • Page 12 The external adjustment for the number of demagnetization pulses per Release cycle is done using the full, residual, release pushbuttons, and the Variable potentiometer. To adjust the number of release pulses, the control must be “at the end of the release cycle”.
  • Page 13: Control Protection

    4.6 Control Protection If the control is switched into sudden high power operation with too large a load, the AC fuse may blow before the electronic protective circuits can function. If the chuck control is overloaded by a short circuit or a chuck too large for this control’s rating, the control will sense this condition and will attempt to protect itself by flashing all the system indicator lights, and the control will not respond to any function selection.
  • Page 14: Grounding & Shielding

    4.8 Grounding & Shielding The optional chuck control outputs for current sense and part released are isolated from the control circuit ground. All other chuck control electrical inputs and outputs, if connected to electronic equipment, must be isolated from the control’s internal circuit ground, which is connected to the AC safety ground (the green or green/yellow wire in the AC line cord).
  • Page 15: Inspection & Maintenance

    5 INSPECTION & MAINTENANCE 5.1 Daily Inspection Check the physical condition of the power cords, indicating lamps, switches, and the control enclosure. If any • deficiencies are observed, contact your supervisor or O.S. Walker. Check the integrity of the enclosure by inspecting for dust, debris, and fluid. Make necessary repairs. •...
