When  the  WARNING/ALARM  display  appears,  take  action  in  accordance  with 
Section 10. "Troubleshooting." 
If the lubrication oil amount is lower than the lower limit line of the oil level gauge, 
supply the lubrication oil.    See the Section 8.4 “Lubrication oil“ when adding the 
oil. 
 

WARNING

 

 

Switch off the power supply to the pump first and interrupt the 

Earth Leakage Breaker (ELB) and lockout before you start on 
maintenance. 

 

WARNING

 

 

The pump and exhaust piping will remain at a high 

temperature  during  operation  and  for  a  short  time  after  the 

pump has stopped. 
Be sure to avoid contact and keep inflammable substances out 

of reach. 

Do not remove the outer cover during operation. 

 

Even  when  the  cause  of  the  WARNING/ALARM  signal  has  been  removed  the 
signal  will  be  maintained  until  the  "RESET"  signal  is  entered.  After  you  have 
taken  the  remedial  action,  press  the  "RESET"  button  on  the  controller  or  enter 
the RESET signal from the control signal connector to reset the WARNING.
