Internal wiring of control unit GENO-OSMO-RO125K
or AVRO 125 TS/TL
The system is completely pre-wired (possibly including options) and
delivered ready to plug in. During commissioning, parameter ECL:1
must be reprogrammed to ECL:0 at code level 113 (NC contact
>>NO contact). This is a protective measure to prevent the system
from being inadvertently switched on after the power cable has been
plugged in, without the system having been vented first.
Jumpers must be plugged in like this
