The BPU can power up to two Norbar display instruments, Electronic Transducer System (ETS), Dedicated Transducer System (DTS) or Torque Wrench Analyser (TWA), or one instrument and one Norbar DATA PRINTER, allowing portability of the whole measurement system. Housed in an instrument style case, the BPU can be stacked with display instruments, printers and 5 way switch units, with the addition of coupling extrusions. A battery management circuit board is incorporated in the BPU to give an indication via a front panel Light Emitting Diode (LED) when approximately 30 minuites life is left in the batteries. If the BPU is used beyond this point it will automatically switch off (indicated by another front panel LED), before inaccurate readings can be obtained. The mains inlet socket on the back panel and internal re-charge circuitry enable the BPU to be recharged via the mains supply. MAINS PLUG FITTING :- ____________________________________________________________ If a mains plug is not fitted, follow the plug’s own instructions. The following may be useful : BROWN-LIVE BLUE-NEUTRAL GREEN / YELLOW-EARTH WARNING! It is important that live, neutral and earth are all connected between the BPU and the mains supply. If no earth is available (2 wire mains supply) it is recommended that a separate earth is connected between the case (the bottom right hand fixing screw in the corner of the back panel is ideal) and a suitable earth. If the plug has an internal fuse, a 1 amp value is recommended. CLEANING :- ______________________________________________________________________ Do not use abrasives or solvent based cleaners. We recommend a propriety brand of foam based fabric / vinyl cleaner. Use a soft cloth to avoid scratches.

Ensure the Battery Power Unit (BPU) front panel ‘FUNCTION SWITCH’ is in the ‘OFF’ position. 2. Fit the BPU connecting cable(s) to the back panels of the BPU and the instrument(s) being used. 3. Switch the front panel ‘FUNCTION SWITCH’ to the ‘BATTERY’ position. The equipment connected to the BPU can only be switched ‘ON’ and ‘OFF’ via the BPU front panel ‘FUNCTION SWITCH’. 4. The equipment connected should now power up, allow 5 minutes for the instrument to warm up and stabilize. For operation refer to operators handbook for equipment connected. BATTERY POWER UNIT OPERATORS HANDBOOK PAGE 5 OF 6 ISSUE 4.0 OCT 1997 RECHARGE INSTRUCTIONS 1. Switch the front panel ‘FUNCTION SWITCH’ to the ‘CHARGE’ position. 2. Ensure mains voltage selector at the rear of the BPU is correctly positioned for your mains supply. Voltage selector indicates 110/120 or 220/240 V AC mains input. To alter voltage selection, firstly remove the mains lead, then place a small screwdriver into the slot and turn until the correct voltage is shown beneath the arrow head. 3. Connect AC mains lead and switch on mains supply to the BPU. 4. The ‘BATTERY CHARGING’ LED should now illuminate. Charge the BPU for 16 hours to ensure the batteries are fully charged. The equipment connected will no longer be powered by the BPU and can only be powered via the mains supply. Note : To obtain maximum battery life and performance, it is highly recommended that the battery power unit is used in a cycle of :FULLY DISCHARGE - FULLY CHARGE (minimum 16 hours) - FULLY DISCHARGE 5. After charging, switch the front panel ‘FUNCTION SWITCH’ to the ‘OFF’ position and remove the mains lead. BATTERY POWER UNIT OPERATORS HANDBOOK PAGE 6 OF 6 ISSUE 4.0 OCT 1997 TROUBLE SHOOTING 1. Charge LED does not illuminate when charging. a) b) c) 2. Check the Voltage Selector is in the correct position for your mains supply. Check the mains power fuse which is located on the right hand side of the voltage selector. Always replace the fuse with the same value and type as originally fitted. Check fuse in mains plug. Battery Power Unit fails to power equipment. If Battery Power Unit (BPU) fails to power the equipment connected after recharging, check the two fuses protecting the batteries that are mounted on the Battery Pack P.C.B. This is achieved by following the proceedure below :- WARNING! 1. Remove the two upper most cross head screws on the BPU front and back panels (four screws in all). 2. Loosen the two lower cross head screws on the front panel half a turn. 3. Lift off the lid. WARNING! 3. Switch off the BPU and remove the power lead. Unplug the batteries from the battery pack p.c.b. before attempting to remove the fuses (2 A anti-surge), and reconnect once the fuses have been replaced. If problems are still incurred, return to Norbar or a Norbar appointed agent, for evaluation. Repair of Battery Power Unit. If there is any doubt concerning the functionality of the Battery Power Unit, it should be returned to Norbar, or a Norbar appointed agent for repair / recalibration.
