The recording feature can be enabled to collect additional data. The simulation can be controlled manually or remotely, with specific stop criteria outlined, such as device alarms or user events.

Master-Slave Operation:
Devices can be connected in parallel in a master-slave configuration to increase total current and power. The Share bus balances units dynamically, and the master-slave bus connects up to 64 units. Wiring guidelines and restrictions are provided, including the need for termination at the bus ends. Mixed systems with different power classes or series are supported, with recommendations for selecting the master unit.

Remote Control and Other Applications:
The function generator can be remotely controlled, with specific commands differing from manual operation. Parallel operation in master-slave mode is detailed, including wiring and setup of the digital master-slave bus. Mixed systems with different power classes or series are supported, with guidelines for selecting the master unit to achieve optimal power output.

Configuring the Master-Slave Operation
- Slave Configuration: Begin by configuring all slave units with the DC output off. Access the Settings menu, select 'Slave' mode, and activate bus termination if needed. Repeat for all slave units.
- Master Configuration: Configure the master unit similarly, selecting 'Master' mode, which enables BIAS resistor termination.
- Initialization: The master initializes the system, displaying results. If initialization fails, repeat the process. The system re-initializes each time the master is powered.
Operating the Master-Slave System
- After configuration, the master displays the total system values. Slaves cannot be controlled manually but can be monitored.
- The master controls the system and shares set values with slaves. It is remotely controllable.
- Alarms on slaves are indicated on the master, requiring acknowledgment to continue operation.
- Loss of connection to a slave results in a shutdown of all outputs, requiring re-initialization.
Alarms and Problem Situations
- Loss of connection triggers an MSP alarm, switching off outputs. Re-initialization or deactivation of master-slave mode clears the alarm.
- Slaves disconnected from AC supply need re-initialization upon return.
- Multiple masters prevent system initialization.
- Alarms are displayed on both master and slave units, with the master showing the most recent one.
Series Connection
- Series connection is possible with restrictions: ensure no potential against ground exceeds specified limits, and remote sensing is not used.
- Series connection is not supported in Master-Slave mode.
SEMI F47 Specification
- Devices must continue operation during a power sag of up to -50% for 1.7 seconds.
- SEMI F47 is disabled if the device boots with low AC voltage and requires decreased max power.
- Activation adjusts power settings and can be stored for future boots.
Service and Maintenance
- No regular maintenance is needed, but fan cleaning may be required.
- Battery replacement should be done by qualified personnel.
- For faults, contact the supplier and follow return procedures.
Firmware Updates
- Updates should address existing bugs or add desired features. They carry risks and should be installed cautiously.
- Review firmware changes thoroughly before updating.
Specifications and Safety Measures:

The equipment is intended to be used only as a variable voltage and current source or only as a variable current sink. Furthermore it's only intended to be used installed and operated in suitable equipment (19” rack or similar), together with a rigid, non-retractable AC supply connection. Typical application for a voltage source is DC power supply to any relevant user, including when used as battery charger to test charge various battery types, and for current sinks the replacement of an ohmic resistor by an adjustable electronic DC load in order to load relevant voltage and current sources of...

• Electrical equipment operation means that some parts accessible on the outside of the device can be under high voltage. Therefore all parts under voltage must be covered during operation! This basically applies to all models, except for the 60 V model according to SELV. • The DC terminal is isolated from the AC input and not connected to ground internally. Hence there can be dangerous potential between the DC poles and PE, for instance caused by a connected external source application. Due to charged capacitors this could even be true if the DC output or the device are already switched off....

The equipment offers various possibilities for signaling alarm conditions, however, not for danger situations. The signals may be optical (on the display as text), acoustic (piezo buzzer) or electronic (status output of the analog interface or digitally readable status bits). All alarms will cause the device to switch off the DC output. For details about the different alarms refer to section "3.3. Alarm conditions". The meaning of the signals is as follows: The operator of the device must decide when to check the device for correct functionality, by whom and how often. The when could either be...
