  • Page 20: Usb Port

    PSI 5000 A Series 1.9.5 USB port The USB port on the back side of the device is provided for communication with the device and for firmware updates. The included USB cable can be used to connect the device to a PC (USB 2.0, USB 3.0). The driver is delivered on the included USB stick or is available as download and installs a virtual COM port.

  • Page 21: Installation & Commissioning

    Preparation Mains connection for a PSI 5000 A series device is done via the included 1.5 meters long 3 pole mains cord. It is required to operate the device with this or a similar cord which features a ground conductor. The ground is important for safety and radio interference suppression.

  • Page 22: Connection To Ac Supply

    PSI 5000 A Series 2.3.3 Connection to AC supply • The device can be connected to any wall socket or power strip, as long as those feature a ground conductor (PE) • When connecting the device to a power strip, along with other electric devices, it is important to consider the total power consumption of all devices on the strip, so that the maximum current (power ÷...

  • Page 23: Grounding Of The Dc Output

    PSI 5000 A Series 2.3.5 Grounding of the DC output Grounding one of the DC output poles is allowed. Doing so can result in a potential shift of the grounded pole against PE. Because of insulation, there is a max. allowed potential shift of the DC output poles, which also depends on the device model.

  • Page 24: Connecting The Analog Interface

    PSI 5000 A Series 2.3.7 Connecting the analog interface The 15 pole connector (Type: Sub-D, D-Sub) on the rear side is an analog interface. To connect this to a control- ling hardware (PC, electronic circuit), a standard plug is necessary (not included in the scope of delivery). It is generally advisable to switch the device completely off before connecting or disconnecting this connector, but at least the DC output.

  • Page 27: Alarm Conditions

    PSI 5000 A Series Alarm conditions This section only gives an overview about device alarms. What to do in case your device indicates an alarm condition is described in section „3.6. Alarms and supervision“. As a basic principle, all alarm conditions are signalled optically (in the display) and as a readable status via the digital interface.

  • Page 28: Manual Operation

    PSI 5000 A Series Manual operation 3.4.1 Switching the device on The device should, as far as possible, always be switched on using the toggle switch on the front of the device. Alternatively this can take place using an external cutout (contactor, circuit breaker) of suitable current capacity.

  • Page 29: Manually Configure Protections

    PSI 5000 A Series 3.4.4 Manually configure protections Along with adjustable set values, the device offers excess protections related to voltage, current and power, which are intended to protect the possibly expensive load hardware. They are configurable in form of adjustable thresh- olds that the device supervises and in case of excess it will switch off the DC output.

  • Page 30: Recall Feature

    PSI 5000 A Series 3.4.6 Recall feature The recall feature is intended to easily recall presets of often used set values (U, I) and protection thresholds (OVP, OCP), except the power set value and OPP threshold. With this, the user can switch between the presets without having to adjust every time again.

  • Page 31: Remote Control

    PSI 5000 A Series Remote control 3.5.1 General Remote control is principally possible via any of the built-in interface ports (USB, Ethernet/LAN, analog). Important here is that only the analog or one digital interface can be in control. It means that if, for example, an attempt were to be made to switch to remote control via the digital interface whilst analog remote control is active (pin Remote = LOW) the device would report an error at the digital interface.
  • Page 32 PSI 5000 A Series Alternatively to setting network parameters manually, DHCP can be activated by command and used by a DHCP server in the network to dynamically assign them. The network setup can be done manually or by DHCP. The transmission speed is set to “Auto negotiation” and means it can use 10MBit/s or 100MBit/s.
