Quick Menu & GraphA quick menu provides access to frequently used features, and a graph function displays real-time voltage, current, and power values. The graph does not record data but provides visual monitoring.

Remote ControlRemote control is available through built-in interfaces or optional modules, with priority given to either analog or digital control. Status monitoring and value reading are always possible.

Control LocationsDevices can be controlled manually at the device or remotely. Remote control can be activated via various interfaces, and manual control is indicated when no remote interface is active. Remote control can be inhibited for safety or adjustment purposes, which requires reactivation once manual control is deactivated.

Remote Control via Digital InterfaceDevices support USB, Ethernet, and optional modules like CANopen, RS232, Profibus, and more. Programming details are available in the "Programming Guide ModBus & SCPI." Interface monitoring ensures the device does not operate uncontrolled if communication fails, with a user-definable timeout to manage this.

Remote Control via Analog InterfaceThe analog interface allows control of current, voltage, power, and resistance. It requires concurrent setting of these values and operates within 0-5V or 0-10V ranges. Alarm thresholds must be set before activation. The interface is protected against over-voltage and requires specific pin configurations for operation.

Device AlarmsAlarms like MSP, OVP, OCP, and OPP require acknowledgment via pin REM-SB. The SOVP alarm requires a power cycle to reset. Alarm indications can be configured in the device settings.

Analog Interface SpecificationsThe interface includes various pins for setting values and monitoring status, with specific voltage and current specifications. The resolution of analog signals is limited by the digital microcontroller, affecting the precision of control.

Application ExamplesExamples include switching the DC output using pin REM-SB, which can lock the output in certain conditions. Remote control of current and power is also possible, with specific configurations required for operation.

Specifications and Configuration:The document outlines the configuration and operation of a power supply system. It details the use of potentiometers to set values for current and power limiting modes, with specific requirements for potentiometer resistance (at least 10 kΩ) due to a maximum load specification of 5 mA for the VREF output. The voltage set value (VSEL) is directly connected to VREF, maintaining a constant 100%. External control voltage must adhere to input voltage ranges of 0-5 V or 0-10 V, with a note that using 0-5 V halves the resolution.

Device Alarm Handling:Alarms trigger a DC output switch-off and display a pop-up notification. Alarms must be acknowledged manually or via remote control. Configurable alarms include OverVoltage Protection (OVP), OverCurrent Protection (OCP), and OverPower Protection (OPP), each with specific thresholds. Non-configurable alarms include Power Fail (PF), OverTemperature (OT), Master-Slave Protection (MSP), Safety OverVoltage Protection, and Share Bus Fail (SF). The document provides steps to configure alarm thresholds and sound settings.

Control Panel Locking:The control panel (HMI) can be locked to prevent accidental changes. The document provides instructions for locking and unlocking the HMI, including the use of a PIN for additional security. Adjustment limits and user profiles can also be locked with a PIN to prevent unauthorized changes.

User Profiles:The system supports up to 5 user profiles, allowing users to save and load settings quickly. Profiles include all settings and set values, and changes can be saved or discarded. Profiles can be imported or exported via USB.

Parallel Operation in Master-Slave Mode:Multiple devices can be connected in parallel to increase total current and power. The document details the wiring and setup of the Share bus and digital master-slave bus, including restrictions and configuration steps. It emphasizes the importance of correct wiring and termination settings for optimal operation.

Master-Slave Configuration and Operation:When connecting devices with different power classes, select the unit with the highest power rating as the master to avoid unexpected power reductions. For example, using a 30 kW unit as the master with a 3 kW unit results in a total of 33 kW, whereas using the 3 kW unit as master results in only 28 kW.

Configuring Master-Slave Operation:

Configure all slave units first by setting them to 'Slave' mode in the settings menu.
Configure the master unit by setting it to 'Master' mode, which enables BIAS resistor termination.
Initialize the master to start the master-slave system, ensuring all slaves are detected and configured correctly.

Operating the Master-Slave System:Once configured, the master controls the system, and slaves cannot be controlled manually or remotely. The master displays total system values and can be controlled via interfaces. If a slave alarm occurs, it must be acknowledged on the master.

Alarms and Problem Situations:If the master loses connection to a slave, an MSP alarm is triggered, and the system shuts down. Re-initialization is required to clear the alarm. If a slave is disconnected from AC supply, it must be re-initialized upon reconnection.

Series Connection:Series connection is possible but restricted by safety and isolation requirements. Remote sensing is not allowed, and only devices of the same model should be connected in series.

SEMI F47 Compliance:Devices must continue operation during a power sag of up to 50% for 1.7 seconds. This feature is implemented in firmware KE 3.02 and HMI 3.02 but cannot be added via update. SEMI F47 reduces maximum power and can be activated/deactivated manually.

Service and Maintenance:No regular maintenance is required, but fan cleaning may be necessary. Battery replacement should be done by qualified personnel. For faults, contact the supplier for repair instructions.

Firmware Updates:Updates should only be installed to fix bugs or add features, using the EA Power Control software via USB. Caution is advised as updates can risk device operability.

Firmware Updates:Firmware updates should be installed only if they solve an imminent problem or if a new feature is desired. Users are responsible for any changes resulting from updates. It is crucial to review the firmware history for changes that may affect device applications. New features may require updated documentation, which might be delayed.

Troubleshooting Device Problems:When connecting a voltage source with reversed polarity to the DC terminal, there is a low probability of damaging the internal secondary power stage. To mitigate this risk, attach warning signs to the device and use fuses in line with DC cables.

Contact and Support:Repairs are generally handled by the manufacturer, and devices should be returned with a fault description and invoice copy if under warranty. For technical support, contact EA Elektro-Automatik via email or phone. Contact details for both the German headquarters and the US office are provided.
