Controller

Function

There are several controllers in the series. The function is deter-mined by the programmed software, but outwardly the control-lers are identical – they all have the same connection possibilities:11 analog inputs for sensors, pressure transmitters, voltage signals and contact signals.

8 digital outputs, with 4 Solid state outputs and 4 relay outputsSupply voltage

24 V a.c. or d.c. to be connected to the controller.

The 24 V must not be retransmitted and used by other control-lers as it is not galvanically separated from inputs and outputs. In other words, you must use a transformer for each controller. Class II is required. The terminals must not be earthed.

The supply voltage to any extension modules is transmitted via the plug on the right-hand side.

The size of the transformer is determined by the power require-ment of the total number of modules.

The supply voltage to a pressure transmitter can be taken either from the 5 V output or from the 12 V output depending on trans-mitter type.

Data communication

If the controller is to be included in a system, communica-tion must take place via the LON connection.

The installation has to be made as mentioned in the sepa-rate instructions for LON communication.Address setting

When the controller is connected to a gateway type AKA 245, the controller’s address must be set between 1 and 119. (1-200 at AK-SM..).

Service PIN

When the controller is connected to the data communication ca-ble the gateway must have knowledge of the new controller. This is obtained by pushing the key PIN. The LED “Status” will flash fast when the gateway sends an acceptance message.

Operation

The configuration operation of the controller must take place from the software programme “Service Tool”. The program must be installed on a PC, and the PC must be connected to the controller via the network plug on the front of the unit.
