Bitzer CRII

The pulse signal can also be used to control one of the CRII with 2 unloaders (4 cylinders version).

Compressor capacity can be controlled from 10 to 100% depending on the pulsation of the unloaders.

The unloaders are connected to DO5 and DO6.

Connect compressor relay to DO-MT1.

Unloader 2 follows unloader 1

but is offset a ½ period.

Important

Read the following before you connect the controller and the two

valve modules to the supply voltage.

Both valve modules are factory set with the same address.

In order to give each module the correct address, you must follow

this procedure:

1. On the two valve modules, remove the terminals with power

supply.

(The power supply is connected later, but in the correct order).

2. Connect the controller to the power supply

3. Check that the main switch is OFF

4. HP module: Mount the terminal with power supply

5. Wait 5 seconds

6. Receiver module: Mount the terminal with power supply.

Wait 5 seconds

All modules now have power supply and the two modules each

have their own address:

96 for the HP module

97 for the receiver module.

The addresses will only be used internally between the three

modules.

If anything has gone wrong, the two valve modules will have acti-

vated the function "EXD reset node ID" and the procedure must be

repeated.

Resetting incorrect addresses in the valve modules:

1. Connect all three modules to the power supply

2. Find the following setting on the controller module

"System"> "Network" > "EXD reset node id's"

3. Set the value to 20

4. Cut out the supply voltage to the valve modules

5. Repeat the earlier procedure.

If you wish to check the addresses of the two valve modules, you

should carry out the following:

1. Connect all modules to the power supply.

2. Immediately press on both the "X" and "Enter" buttons while the

controller is starting up.

3. Find the display "CAN SETTINGS" > "ACTIVE NODES"

The two 1-digits represent the addresses 96 and 97 respec-

tively.

If you remove the connection to a valve module, the display of

the address will also disappear.
