Introduction

This chapter describes the general characteristics and main features of the F1K5DISS power dissipation unit.
1.1 F1K5-DISS Overview
The FAST-PS-1K5 by CAEN ELS is an independent current- or voltage- controlled digital bipolar power supply module. Standalone, the FAST-PS-1K5 is a bipolar power converter able to work in the positive current/positive voltage and negative current/negative voltage quadrants only continuously.
The F1K5-DISS unit adds current/voltage sinking capabilities to the system so that a FAST-PS-1K5 together with a F1K5-DISS becomes a full 4-quadrant system
capable not only sourcing but also sinking up to 1.500 W.
There are two commercially available models for the F1K5-DISS unit that can be matched to specific models of the FAST-PS-1K5 power unit:

Table 1: F1K5-DISS models
The F1K5-DISS module is compact and fits in a single 19-inch 1U standard crate. The whole system together with a FAST-PS-1K5 fits in a 19” – 3U slot.

Installation

This chapter contains the main instructions for initial inspection and preparation for use.
2.1 Preparation for Use
In order to put the system into operation, the power supply must be connected to an appropriate AC source. The AC source voltage should be within the power supply specification. Do not apply power before reading this manual. Table 2 Error! Reference source not found.lists the basic setup procedure. Follow the instructions in the given sequence to prepare the power supply for use.

Table 2: Installation checklist
2.2 Initial Inspection
Prior to shipment, this F1K5-DISS unit was inspected and found free of mechanical or electrical defects. Upon unpacking of the power supply, inspect for any damage which may have occurred in transit.
The inspection should confirm that there is no exterior damage to the power supply such as broken switches or connectors and that all panels and display are not scratched or cracked. Keep all packing material until the inspection has been completed. If damage is detected, compile the RMA form available to the CAEN ELS web site.
2.3 Mounting
The FAST-PS-1K5 & F1K5-DISS system can be used either as a desktop unit or as a rack-mount device since the unit form factor is designed to be installed in a standard
3U 19-inch cabinet.
CAUTION
This system is fan cooled, the air intake is at the front panel and the exhaust is at the rear panel. Upon installation allow cooling air to reach the front panel ventilation inlets. Allow minimum 10 cm of unrestricted air space at the front and 20 cm on the rear of the unit.
Rack Mounting
The FAST-PS-1K5 & F1K5-DISS system is designed to fit in a standard 19” equipment rack.
CAUTION
Use a support bar to provide adequate support for the power supply.

Desktop Use
The FAST-PS-1K5 & F1K5-DISS system can be used as desktop unit but every precaution must be used to avoid touching the output connectors because of the high energy source.
WARNING
User shall protect output contacts by placing the FAST-PS1K5 & F1K5-DISS system inside a closed rack or by restricting the access to the back side.
2.2.3 Thermal Management
F1K5-DISS converts electrical into thermal energy, considerable amount of heat is generated. This fact must be taken into consideration when installing the system. Fans cool the dissipation element by drawing air from front side and exhausting it out the back, therefore minimum 10 cm of unrestricted air space at the front and 20 cm on the back of the unit must be provided.
If specific application requires high power dissipation for long periods (> 800 W; > 10 min) it is recommended to install FAST-PS-1K5 and F1K5-DISS with 1U of clearance in between to mitigate heating problems and using blanking panels to prevent mixing hot and cold air. Proper equipment rack ventilation shall be provided to reduce ambient temperature not exceed 45 °C on the front of the units.
WARNING
Do not touch the hot surfaces. The temperature of the back and top-right surfaces may be high when the unit is operating at high power.

2.4 F1K5-DISS connection
WARNING
Turn off the AC input power before making or changing any rear panel connection. Ensure that all connections are securely tightened before applying power. There is a potential shock hazard when using a power supply with a rated output greater than 60 V
2.4.1 Power Connection
It is recommended to use original cables that are contained with the unit. If custom longer connection is required keep wire size of main power connection at 16 mm 2 (AWG 6) and not longer than 1m. Strip wires insulation back 15 mm and push them straight into the power plug and screw them tightly. Be sure that they fit well and make a good contact.
Connect main power cable to DISSIPATIVE UNIT connector on FAST-PS-1K5 and to FAST-PS-1K5 connector on dissipation unit. Secure cable assembly with connectors screws on both ends.

2.4.2 Status Cable Connection
Connect the supplied coaxial cable to STATUS BNC connector on F1K5-DISS side and AUX2 BNC connector on FAST-PS-1K5 side.

2.5 FAST-PS-1K5 Connections
For installation and connection instructions refer to FAST-PS-1K5 User’s Manual, chapter 2.
2.6 FAST-PS-1K5 Configuration
FAST-PS-1K5 in standalone configuration has 100 W of negative power. Even if dissipation unit is connected to main power converter 100 W limit is still active and system will go in fault if this limit is exceeded. To achieve full current sinking capability when using dissipative unit this option must be enabled in FAST-PS-1K5 configuration. Power converters purchased together with F1K5-DISS dissipation unit have this option already enabled by default.
To enable (or disable) full current sinking capability use FAST-PS-1K5’s web server interface. Under CONFIG tab select INTERNAL MEMORY. Set Value of ID 54 (Dissipative enabled on AUX2 at start-up) to “1”. For more information on configuration refer to Remote Control Manual.
Whenever changing this parameter FAST-PS-1K5 must be power-cycled for new value to be valid.
2.7 Front Panel LED Indicator
The F1K5-DISS has front panel LED indicator as shown in the Figure 3.

The front panel indicator and its behaviour is outlined in the following table:

temperature
RED| Solid| Error condition
RED, GREEN, ORANGE, OFF| Blinking in circular fashion| Firmware Update mode

Table 3 – Front-panel LED behaviour
Status LED in green indicates the module is connected properly and fully operational. Solid red at power-on means that wrong FAST-PS-1K5 was detected. LED will flash orange to indicate warnings; the module is sinking current when flashing interval is short, warning may be for the following reasons: high power, high temperature or fan malfunction. When interval is long the module is not active, warning indicates fan malfunction or high temperature of the module caused by just finished power dissipation. Solid red is reserved for major errors: thermal overload, too high input current, too high input power or hardware failure. In all this cases dissipation unit reports error to FAST- PS-1K5 which then disables its output and activates crowbar function to prevent potential or further damage.
When in firmware update mode LED will be changing colours. FAST-PS-1K5 will automatically disable its output.

Firmware Update

If a firmware update is necessary, this can be done using Firmware-Update.exe utility. It requires the C run-time libraries (CRT), if not already installed you can do it by running “vcredist_x86.exe” which can be found in the same directory ad firmware update utility on supplied USB Flash drive.
3.1 Firmware Update Procedure
Save the file to your computer and note the directory where the file is saved. A firmware update is a file with a “.hex” extension. Preferably save it in the same directory of Firmware-Update.exe utility.
To perform the update F1K5-DISS must be connected to FAST-PS-1K5 which must be switched on with its output disabled. Never try to update if FAST-PS-1K5 output is not disabled.
Connect the computer’s USB port to the F1K5-DISS’s USB-B port with a USB cable.
Using Windows Device Manager identify COM port number – locate Ports (COM & LPT) in the list, expand it and check for USB Serial Port. Open Command Prompt (CMD) and change directory to folder where Firmware-Update.exe resides. Launch update utility with following parameters:

• a firmware update filename with path – mandatory
• p COM e.g. COM9 – mandatory
• b baud rate – optional

Firmware update takes ~30 seconds with default baud rate. After successful completion front panel status led turns blinking green and the module is ready to use.
