8.14 - Circuit capacity loading sequence

This function determines in which order the circuit capacity 
is changed. Compressor loading is based on compressor 
control. 

Two  types  of  compressor  loading  sequences  are  available 
and  can  be  configured  by  setting  the  Loading  Sequence 
parameter  [seq_typ]  via  the Touch  Pilot  user  interface 

(GEN_CONF).

• 

Balanced loading sequence (“seq_typ” set to “no”):

 

The control maintains equal capacity between both 
circuits as the machine loads and unloads. The lag circuit 

can be started when the pre-defined capacity of the lead 
circuit is reached, i.e. 50% by default.

• 

Staged loading sequence (“seq_typ” set to “yes”):

 

The control loads the lead circuit completely before 
the lag circuit is started. When the load is decreasing, 

the lag circuit is unloaded first. 

To set loading sequence

1.  Navigate to the Configuration menu.

2. Select 

General Configuration

 (GEN_CONF).

3. Set 

Staged Loading Sequence

 [seq_typ].

Staged Loading Sequence [seq_typ]

no = Equal loading sequence

yes = Staged loading sequence = Circuit B priority

To set capacity required to start the second circuit

1.  Navigate to the Configuration menu.

2. Select

(GEN_CONF).

8.15 - Master/Slave assembly (option 58)

Two units can be linked to create the master/slave assembly. 

The master unit can be controlled locally, remotely or by 

network commands. Master/slave assembly must be validated 
in order to start the master/slave chiller operation.

All control commands to the master/slave assembly (start/

stop, setpoint selection, load shedding, etc.) are handled by 

the unit which is configured as the master. The commands 
are transmitted automatically to the slave unit. If the master 
chiller is turned off while the master/slave function is active, 
then  the  slave  chiller  will  be  stopped.  Under  certain 
circumstances, the slave unit may be started first to balance 

the run times of the two units.

In the event of a communication failure between the two 

units, each unit will return to an autonomous operating mode 
until the fault is cleared. If the master unit is stopped due to 

an alarm, the slave unit is authorised to start.

NOTE:

 Master/slave assembly can be configured only by 

Carrier service technicians.

8.16 - Energy Management Module (option 156)

The energy management module (EMM) enables to control 

the  level  of  energy  consumption,  providing  users  with 

information such as current unit status, compressors 
operating status, etc.

This option requires the installation of an additional SIOB 
board.
