  2. 2. TM Oil Immersed Starter l l l l l l l Oil immersed Direct On-Line Starters ranging from 3 HP to 10 HP Oil immersed Direct On-Line Starters (Heavy Type) OBHD series ranging from 10 HP to 20 HP Oil immersed Hand operated Star Delta Starter ranging from 5 HP to 35 HP Motor Starters Oil immersed Starter Direct on-line with magnetic / Thermal over load relay Contacts made of electrolytic copper material with double break system ensure long life and better conductivity of contacts. No Volt coil, Tripping coils and Contacts are immersed in oil which absorbs sparking of contacts and coil temperature. No Volt coils are designed to withstand wide voltage fluctuations. The magnetic type over load release with adjustable oil dash pot time lag device works on the principle of current and not dependent on the temperature, it enables fine adjustment of the setting even to a fraction of an Ampere, thus eliminating the use of single phase preventor. Range 3.0 HP - 20.0 HP Instructions Before energizing, remove packing materials and tag along with cotton tape from guides. Fill in the tank with good quality transformers oil up to the level mark before energizing (2.25 litres for DOL, 3.25 for HDOL, and 4.25 litres for SD). Oil must be checked periodically and change oil for better life. To start the motor press and hold the green colour push button for at least 5 to 10 seconds for proper functioning in the case of D.O.L starter. In the Star Delta Starters, bring the handle to “Star” position, then press and hold green colour push button until the motor gets energized and shift the handle to “Delta” position. it is not possible to put the handle into “Delta” position without going through “Star” position. Oil immersed Star Delta Starter Semi Automatic / Automatic The starter is consisting of three contactors. In the semi automatic starter, the time delay extends over the period when the start button is kept pressed. The changeover from star to delta takes place at the instant when the start button is released. In the automatic starter, delay timer is provided. It changes from star to delta automatically in the preset time.

  3. 3. TM Air Break Direct On Line Starter & Star Delta Starter l l l l l l l l Air Break Direct Online Starter ranging from 1 HP to 10 HP (3 Phase) can be convertable to single phase also. Air Break Semi Automatic and automatic Star Delta ranging from 5 HP to 15 HP Motor Starters Air Break Starter Direct On - Line Air Break Starter Star - Delta Semi Automatic/ Automatic Contact tips made of thick AgCdo material to withstand extreme field conditions. No Volt coils are designed to withstand wide voltage fluctuations. Bimetal Thermal overload relays are calibrated as per IS standards will trip off accurately during overload and in phase failure conditions. A latch is provided to prevent accidental starting. Air break starters are suitable for variable load condition motors with external panel operations such as limit switch and other electronic controls. Range 1.0 HP - 10 HP Range 5 HP - 15 HP Air Break Starter Direct On - Line Single Phase Housed in an attractively powder coated steel enclosure.

  4. 4. AIR BREAK / OIL IMMERSED STARTERS - INSTRUCTIONS l l As given in selection table starter relay ranges are for surface motors. The next higher relay range must be selected in case of submersible motors where the full load current is higher than the surface motor. While placing order please specify motor HP, Voltage, Full load current rating and coil voltage. l In case of high torque motors, special model starters can be supplied on request. l The local electrical codes and regulations must be followed for installation. l Air Break Starter must be mounted vertically upright l l l l l l Starter must be protected from rain and direct sunlight. It must have good air circulation and be away from high temperature locations. Starter location should be easily accessible for regular inspection and be relatively free from dust, fumes and moisture. Starters must be selected with suitable relay range as per motor rating shown in the selection table. Turn the current adjustment knobs to set full load current of motor mentioned in the motor name plate. Check screws for tightness and give proper earthing to avoid shocks. Starters must never be used without backup fuses. HRC fuses are preferable for protecting the installation as well as the relay of the starter against short circuits. For reverse rotation of motors, interchange any two supply lines. Pilot circuit fuses must be used incase of remote control operation to protect pilot wiring, which is not adequately protected by the backup fuses. l There should not be any loose connections in incoming and outgoing terminal. l Please refer operator’s manual supplied along with starter for wiring diagram. l The ambient temperature should not exceed 40 0C USE OMAX GENUINE SPARES FOR LONG LIFE AND BETTER PERFORMANCE PRAVIN ENGINEERING TM Motor Starters Site No. E-1, Vasantha Nagar Street No-6, Behind E-B Office, Singanallur, Coimbatore - 641 005.Tamilnadu, INDIA Phone : 91-422 - 2272419, 3253253 Mobile : 93622 06195 E - mail : omaxstarters@gmail.com Web : www.omaxstarters.com www.omaxstarters.com
