 MAINTENANCE AND TROUBLESHOOTING 

Although  transmitters  SST7X  do  not  require  a  maintenance  on  periodical  basis,  it  is  good 
practice  to  regularly  check  the  general  transmitter  status,  the  possible  presence  of  rust  or 
damage on the case or on the measuring diaphragm and the presence of clogging in the process 
connection. At the end of 10 years, the equipment must be subjected to a check of integrity of 
the components, through the thickness check and the hydrostatic test. 
 

 

P

ROHIBITION

! 

Repair, maintenance and/or overhaul of the equipment shall only be conducted by 
the manufacturer himself, or by a repairer he has qualified or authorized.

 

Is forbidden during the maintenance operation to use the 
instrument as a handle or step. 

 

 
Please refer to the following pages scheme for troubleshooting. 
In any case contact our technical department for help. 

 

 

 

Condition 

Potential 

source 

Solution 

The transmitter 

doesn’t turn on 

Supply 

Check the supply voltage to be 12.5Vdc <V

supply 

<30Vdc. 

Polarity 

Check the transmitter connection polarity. 

Electrical load  Check that the load is less than the maximum allowed. 

Measure is 

incorrect 

Process 

Accurately verify the compatibility between the process 
and the connection type. 

Sensor drift 

Apply zero input conditions to the transmitter and use 
the OFFSET command. 

EMC 

interference 

Accurately verify the possible presence of 
electromagnetic interference on the supply line. Check 
the PE connection.
