1. Please check Valve does not switch 1 Solenoid a No power connected b plug mounted the wrong way c Voltage incorrect d confused and poles e Solenoid out of order ad 1 a Check power source b plug mounted correctly c Voltage might vary 10 from nominal voltage d check and poles If the solenoid was connected to confused poles check whether existent diodes are still OK d Remove solenoid from valve and check the stroke 2 Hydraulical or pneumatical actuator a no pressure b pressure too low ad 2 a check pressure source b set pressure source to appropriate value Dr Breit GmbH 49 0 2056 58070 fon Carl Zeiss Str 25 49 0 2056 580799 fax Visit us at www dr breit de 42579 Heiligenhaus mailbox dr breit de Troubleshooting Hydraulik Pneumatik Elektronik malfunction Possible cause Please check Valve does not switch back remains in middle position 1 Flow too high ad 1 Throttle the flow from P gt A or from ADT 2 Pressurized T port if valve is pilotted ad 2 Check pressure in T port lt 10 bar is OK If valve is of Eex ia type make sure pressure in T port is down to 0 bar 3 contamination ad 3 Refer to Leakage at T port Valve is switched but no flow or malfunction 1 P line out of function ad 1 a Is the valve pressurized b Is the right pressure l2. Troubleshooting Hydraulik Pneumatik Elektronik Malfunction Possible cause Please check Leakage at T port 1 3 2 NC 2 2 NC untight P poppet or 3 2 NO untight T poppet if valve is not switched Dirt inside the valve or poppet out of function ad 1 Open springcup dismantle ball and clean the poppet not possible with 3 2 and 2 2 NO then only dismantle the valve or If valve is contaminated dismantle cartridge clean it and reassemble the valve 2 3 2 NC untight T poppet or 3 2 NO 2 2 NO untight P poppet if valve is switched Dirt inside the valve or poppet out of function ad 2 First try to adjust the valve acc to the adjustment manual If this does not help dismantle the cartridge clean it and reassemble the cartridge before readjusting it finally If this does not help use a new cartridge assemble and adjust the valve 3 3 2 NC 2 2 NO untight although not switched fluid exits T port ad 3 If fluid exits T port this could pretend leakage although valve is tight Wait a few seconds to see if leakage stops If it stops no action is needed Dr Breit GmbH 49 0 2056 58070 fon Carl Zeiss Str 25 49 0 2056 580799 fax Visit us at www dr breit de 42579 Heiligenhaus mailbox dr breit de Troubleshooting Hydraulik Pneumatik Elektronik malfunction Possible cause
3. ine connected to the valve 2 Additional hydraulic components upstream downstream ad 2 If the system is pressureless upstream components to the valve might be out of function 3 Valve is mounted the wrong way on its manifold ad 3 make sure the valve is mounted the right direction on the manifold Refer to installation manual and connect P to the P port A to the A port Dr Breit GmbH 49 0 2056 58070 fon Carl Zeiss Str 25 49 0 2056 580799 fax Visit us at www dr breit de 42579 Heiligenhaus mailbox dr breit de Troubleshooting Hydraulik Pneumatik Elektronik malfunction Possible cause Please check Valve is switched flow is insufficient 1 Too little flow ad 1 Is the flow PSA or ADT throttled THEN If additional orifice is plugged inside one of the ports P or T please remove OR Choose for a bigger valve size Dr Breit GmbH 49 0 2056 58070 fon Carl Zeiss Str 25 49 0 2056 580799 fax Visit us at www dr breit de 42579 Heiligenhaus mailbox dr breit de
