6. Eliminating Operating Troubles (Error detection) SWITCHING ON NOT POSSIBLE „Activating magnet doesn't work electrical but (after making sure it's not alive!) works mechanical with the hand lever." • Control voltage Us not available or to low? Check, if voltage delivered by the power supply is not available or to low (measure points :4/:5) • Voltage loss to large at the coil of the activating magnet? Measure or calculate control voltage Uc of the magnet. • Control cable interrupted or not correct connected ? • If control voltage o.k. change circuit board. • Note the polarity of the power supply. Check measure points :1/:2 at plug X2 and measure points :4/:5 at plug X3. • Check if error in customized auxiliary control circuit. • Activating magnet faulty? (Change it). „Activating magnet works electrical“ • If available, check r-release - Control voltage available? - Feeding and connection o.k.? - r-release coil faulty? • Check, if positive tripping is wrong adjusted. • Faulty mechanic? (Call service department) Switching off the breaker not possible „a-release don't release“ • Control voltage available ? • Control plug o.k.? • Control cables o.k.? • a-release faulty? (change it) • Auxiliary switch HS 11 wrong adjusted? • Faulty mechanic ? (call service department) „r-release don't release“ • Faulty mechanic ? (call service department) „ed-trip unit don't release“ • Capacitors circuitboard faulty? (change it) • Interface of line measuring device faulty? Faulty circuitboards • Change the complete circuit board 39
