SBH-E : REV A DiBO n.v. 178
Connecting a Frost-Protection Unit to the SBH-E
The SBH-E (since 2005) is prepared for connecting a Frost-Protection-Unit. Therefore no
electrical changes are necessary.
The software is also prepared but you must let the SBH-E know that a Frost-Protection-Unit
is attached. To do this, you change the settings (of the Dibo steering, see manual 5.2.1) At and
Ut, to 9999. Now the SBH-E is ready to use the Frost-Protection-Unit, and the internal
frostprotection is deactivated.
Connecting the Frost-Protection-Unit:
Electric:
* connect the defrost-pump to X1 (6-7-PE) (pic 2.1)
BE CAREFULL : CHECK THE SUPPLY TENSION N or 3x230V.
In case of 3X400+N connect K3-3 to N, in case of 3x 230V connect K3-3 to L 2 or L3.
* connect the heating element to X1 (11-12-13-PE) (pic 1.2)
BE CAREFULL : CHECK THE SUPPLY TENSION N or 3x230V.
In case of f 3x230V => triangle, in case off 3x400V => star
* check Q3 (Thermic defrost-pump), the display returns a fault code (E-FP) if
you switch Q3 off.
* connect NR1 (dryrun frost-boiler) to X2 (23-24) (pic 1.3)
* connect ST2 (thermostat frost-boiler) to X2 (3-4) (pic 1.4)
* connect KL4 (HP-valve lance) to X2 (13-14) (pic 3.4 )
* connect KL5 (HP valve brush) to X2 (15-16) (pic 3.5)
Low Pressure Water:
* connect the frost-boiler (float-valve) to the water supply (pic 1.1)
* connect the frost-pump output to the filter (pic 2.1 , 3.6)
High Pressure Water:
* connect the HP output from the smartwash to the HP valves (pic 3.3)
* connect the lance and brush to the HP (pic 3.1 , 3.2)
PAY ATTENTION: ALWAYS CHECK THE ELECTRIC PLAN ON POSSIBLE CHANGES! IT CAN BE POS-
SIBLE THAT THE ELECTRIC CONNECTIONS MENTIONED ABOVE ARE NOT BY DEFAULT.
