1. Example for version RS and SR:  

System with 4 compressors, 1 backup compressor, 
[BASE LOAD COMP 3], fault K4 

Before the fault:  
103h K1 K3

On moving to the next BLS array, the new BLS array is 
newly configured with the machines available.

BLS active message 

The slave compressors normally have their own or an 
internal pressure switch for controlling on-load/off-load 
operation. In conjunction with coupling relays, the BLS 
active message can be used to disconnect the slaves 
from their internal pressure switches, i.e. control takes 
place exclusively through the master's load request.  

If the BLS system fails, the slave compressor can, in 
this way, switch over to its own pressure switch.  
 

2.9.1

 

Via the spare-out output (option) 

The BLS active function can be activated via the 
master's spare out using code 9348. The relay is pulled 
in when [OPERATION ON/TIMER] is active. The relay 
drops out if the following events prevent the BLS master 
from passing on load enables to the machines 
[OPERATION OFF/—]: 

1.  BLS is deactivated in the menu 

2.  Master without power supply 

3.  Fault: network pressure sensor B1 

4.  Warning: MS bus: A06 (relay module failed for 

activating slaves) 
 

2.9.2

 

Via the BLS module 

If the sum of slaves and backup machines is less than 
four, one relay is unused on relay module A06. This 
relay then accepts the BLS active message. This way, 
the spare out can remain free for other messages.  
 
 

2.10

 

Messages to higher-order system 
when BLS is not activated 
(version RS and SR only) 

If the number of slave + backup compressors = 0 and 
the BLS operating mode = OFF, the relay outputs on 
the BLS module report the following: 

Relay A06.0  The speed-controlled machine is at 100% 

full load 

Relay A06.1  The speed-controlled machine is in off-

load mode 

Relay A06.2  The speed-controlled machine is in on-

load mode 

Relay A06.3  Version RS: Speed control activated (not 

off or being bypassed) 
Version SR : Reserved
