Page 17: Construction And Function
General description The electronic high performance power supplies of the PSI 9000 WR 3U Slave are designed to extend the power of compatible models from series PSI 9000 WR 3U. The slave models are reduced to basic functions and will usu- ally run in remote control from a master of a master-slave system. -
Page 18: The Control Panel (Hmi)
Doing so is only necessary and possible in these two situations: 1. The PSI 9000 WR 3U Slave shall run as stand-alone device which is not controlled by a PSI 9000 WR 3U master. 2. The PSI 9000 WR 3U shall, due to the lack of a suitable PSI 9000 WR 3U master device, be the master of other PSI 9000 WR 3U Slave devices. -
Page 19: Share" Connector
1.9.7 “Sense” connector (remote sensing) The devices of series PSI 9000 WR 3U Slave are supposed to run as slave units in a master-slave system where the remote sensing feature is only used and connected to the master unit. For stand-alone operation outside of a master-slave setup this feature can be wired and used on the Slave mode as well. -

Page 31: Alarm Conditions
PSI 9000 WR 3U Slave Series Alarm conditions This section only gives an overview about device alarms. What to do in case your device indi- cates an alarm condition is described in section „3.6. Alarms and monitoring“. As a basic principle, all alarm conditions are signalled optically (by LED “Error” on the front) and via the digital interface ports. -
Page 32: Manual Operation
PSI 9000 WR 3U Slave Series Manual operation Manual operation is a secondary functionality for this type of device. It is intended to run under constant remote control by a master unit. Thus the number of available functions in manual control is reduced, compared to a standard PSI 9000 WR 3U device. -
Page 33: Remote Control
PSI 9000 WR 3U Slave Series Remote control 3.5.1 General Remote control is essential when operating devices of this series, for example during master-slave.

Page 35: Alarms And Monitoring
PSI 9000 WR 3U Slave Series Alarms and monitoring 3.6.1 Definition of terms The device signalises alarms (see „3.3. Alarm conditions“) such as overvoltage (OV) or overheating (OT) via the front LED “Error” and as readable status via digital interface. When running the device as Slave as part of a master- slave system, the alarm is also reported to the master and if the master is with display, the alarm is indicated there as well. Basically, device alarms will switch off the DC output, primarily in order to protect the connected load and... - Page 36 PSI 9000 WR 3U Slave Series 3.6.2.1 User defined events The monitoring functions of the device can be configured for user defined events. By default, events are deac- tivated (action = NONE). Contrary to device alarms, the events only work while the DC output is switched on. It means, for instance, that you cannot detect undervoltage (UVD) anymore after switching the DC output off and the voltage is still sinking. The following events can be configured independently and can in each case trigger the actions NONE, SIGNAL, WARNING or ALARM.

Page 37: Other Applications
This can be done using the standard models with display or the new slave models (PSI 9000 WR 3U Slave, available since mid of 2017). Only disadvantage: the slave models are only available as 15 kW versions, so they only match the 15 kW standard models. - Page 38 PSI 9000 WR 3U Slave Series Later operation of the MS system implies: • The master unit calculates the sum of the actual values of all the units and makes them available to read via the digital interfaces • The ranges for setting the values, adjustment limits, protections (OVP etc.) and user events (UVD etc.) of the master are adapted to the total number of units.
