The texts can be readin context with the table in point 4.Analog inputsTemperature sensorsTemperature sensors that can be used by thermostats formonitoring, relay control and alarm functions (Saux1 - Saux10).Voltage signalVoltage signals that can be used for monitoring, relay control andalarm functions (Volt input 1-5).Pressure transmittersPressure transmitter signals that can be used by pressostats formonitoring, relay control and alarm functions (Paux1 - Paux5).On/Off-inputsContact function (on an analog input)orVoltage signal (on an extension module)On/off signals that are used for monitoring, relay control andalarm functions (DI1-DI16).• Defrosting signals that are used to extend alarm delays forthermostats.• Appliance cleaning signal to stop alarms from the thermostat.• Signal to reset the alarm relay (mute function).Pulse inputs• Energy reading• SynchronisationOn/off outputsRelay outputs• Thermostat functions 1-10• Voltage signals 1-5• Pressostat functions 1-5• Digital input functions 1-16• Alarm relays 1-23Data from this example is used on the next page.The result is that the following modules should be used:• AK-LM 330 Monitoring unit• AK-XM 102B extension module with digital high voltage inputs• AK-XM 107A extension module with pulse inputs• EKA 164BExample• Temperature reading with temperature shown on the display(Saux1)• Temperature reading (Saux2) and one 230 V signal for activationduring defrosting so that the alarm delay is postponed (DI1) andone 230 V signal detecting that the appliance is not in operation(DI2).• Temperature reading with relay function (Saux3).• Voltage reading (U1).• Voltage reading with relay function (U2).• Pressure reading to 12 bar (Paux).• Pressure reading with relay function to 34 bar (Paux2).• 230 V signals from compressor monitoring (DI3 and DI4).• Pulse signal from gauge unit (E).• Alarm relay (AL) ("mute" of alarms takes place from the externaldisplay).
