7.13 Wiring of the master-slave function for defrost synchronisation
For defrost synchronisation the auxiliary contactors of the master defrost relay are switched in parallel and
then routed as a 230 V signal to the slave’s external defrost input (terminals D11/D12). The auxiliary contactors
of the slave controller are also connected in parallel and conducted back as a 230 V level to the external
defrost input of the master. This enables the software to determine whether defrosting is still taking place in
both case controllers.
Warning - hazardous electrical voltage!
Danger of electric shock! BEFORE and AFTER
connection it must checked that the 230 V AC digital
inputs are off load!
The description and operating instructions for the master-slave mode are contained in chapter
slave mode – defrost synchronisation via wiring
.
Danger of short circuit!
When wiring master and slave case/coldroom controllers, make sure that
power supply is made with only
one
phase (e.g. only through L1, see illustration)!
Defrosting is terminated by the software not later than when the set safe defrost time expires. The
external clock must be wired as a passing contact as it only provides the start signal for the defrosting.
The shutdown is entirely managed by the participating controllers according to their safe defrost time.
