S88-4

English

9. Check list for troubleshooting

Parts are getting too hot and/or start to smoke.

Disconnect the system from the mains immediately!

Possible cause: one or more components are soldered incorrectly.

à

 In   case   you   have   mounted   the   module   from   a   kit,   perform   a

visual   check   (

à

  section   6.)   and   if   necessary,   remedy   the   faults.

Otherwise send in the module for repair.

The   central   unit,   the   memory   or   the   interface   do   not   show   the
proper status.
Possible cause: The connection(s) between the feedback module and
feedback   modules   connected   in   series   or   the   digital   device   are 
interrupted.  

à

  Check the connections. When using a ribbon cable,

check as well, if the connecting socket of the ribbon cable is put on
in the right direction. 
Possible   cause:   The   connection   between   the   input   and   the   mass
contact is interrupted. 

à

 Check the connections. 

The control unit / the memory / the interface always displays in a
specific situation the same false status. 
Possible  cause:  You  have   assigned  another  address  to the  S88-4
module than required.   Check the address.

The   control   unit   /   the   memory   /   the   interface   display   does   not
display the status of one module.  
Possible cause: You have assigned an address to a S88-4 module
that is occupied by another S88-4 module or a standard module. 

Check the addresses.
