Description of functions

Controllers are featured with a main function as superheat controller or temperature controller. The main function is selectable.

Superheat control of evaporators or economizers

This function requires the connection of temperature sensor(s) as well as pressure transmitters(s). The other functions are:

• MOP control: enables the limitation of saturated temperature of suction line (outlet of evaporator/economizer)

• Low pressure behaves similar to low pressure switch including alarm conditions

• Freeze protection is based on saturated temperature from converting measuring suction pressure. It provides alarm condition

below certain adjusted temperature.

Temperature controller

The function is to maintain desired temperature by modulating refrigerant mass flow. If controller is operated as temperature controller, the connection of pressure transmitter is not required. In order to fulfill varieties of the applications, the refrigerant mass flow variation can be set according temperature increase or decrease.

(A: Mass flow increases if temperature rises)

Valve opening %

100%

Temperature 0%

Examples of applications:

• Temperature control by throttling suction mass flow (normal sense, A)

• Temperature control by modulating hot gas into inlet or outlet of evaporators (reverse sense, B)

• Discharge temperature control by injecting liquid (normal sense, A)

• Head pressure control by means of temperature control (normal sense, A)

EXD-SH1/2 Controller for electrical control valves with ModBus Communication Capability

Communication

The use of communication is not necessary/mandatory; however, the communication is available for connection to upper level of system controller (third party controller) in order to perform data and commands transfer as well as data logging. EXD-SH1/2 act as slave and third party controller is master. In case of several EXD-SH1/2 connections to master, each driver needs to be addressed for proper communication.
