Page 6: Installation
Caution: In many cases, the Reversal Switch and DC Power Supply will be pre-installed by GMW into a 19” EIA equipment rack. If it is not, care should be taken during rack mounting to avoid personal injury or damage to the equipment. -
Page 7: Electrical Connections
3.3 - Electrical Connections Even if the 5971-160 Reversal Switch was ordered as a complete system and assembled into a rack by GMW, it is still recommended to follow and verify the following section as connections may have loosened during shipment. -
Page 8: System Description
4.1 - System Description A complete system would typically consist of an appropriate SGA series DC power supply, the GMW 5971-160 Reversal Switch, a Senis magnetic field transducer, an electromagnet and an appropriate computer and software or an external analog programming signal. -

4.4 - Computer Control The 5971-160 is provided with a LabVIEW driver that allows basic control and monitoring of the Reversal Switch and DC Power Supply. To use the external control option, set the ‘Control Mode’ switch on the rear panel to ‘Internal’. This connects the internal DAC to the DC Power Supply analog control input. -

5971-160 Reversal Switch. If GMW’s Magnet Control software is not used, it is still possible to computer control the 5971-160 Reversal Switch by writing custom software to communicate with the USB-6251. The table below describes the channels used and their functions. -
Page 12: Software
Section 5 SOFTWARE The 5971-160 Reversal Switch is provided with basic control and monitoring software. This section covers the installation and basic operation of the software. 5.1 - Software Installation Install the software packages in the order below. This should ensure that all components are correctly installed and working. - Page 13 5.2.2 - Software Configuration Upon the first run of the software, a simple configuration screen will be presented. Select the DC Power Supply type from the provided list. If the power supply that is being used is not listed, enter the maximum voltage and current of the DC Power Supply that you have.
- Page 14 5.2.4 - Local / Remote The Reversal Switch software defaults to local operation. In order to control the Reversal Switch it must first be placed into the ‘Remote’ mode. This is done by clicking on the Local / Remote’ Control. This control will change its state depending on what mode it is in.
- Page 15 5.2.5 - Setting the output current The output current is simply set by entering the desired output current in the current control box. Setting the Output Current...
- Page 16 5.2.6 - Selecting the Reversal Switch polarity To change the Reversal Switch polarity, simply click on the polarity control toggle. The Reversal Switch will then inhibit the DC Power Supply’s output, wait for the voltage to drop to a safe level, change polarity and then re-enable the DC Power Supply’s output.
- Page 17 5.2.7 - Timed Switching The software has the ability to automatically switch at a rate chosen by the operator. To use the timed switching function follow the procedure below. 1. Push the ‘Enable Timer’ button. 2. Enter the desired time switching interval in seconds. Note that 30 seconds is the minimum interval.
- Page 18 5.2.8 - Data Logging There are a few things to set up in order to use the data logger: 1. Push the ‘Create Log File’ button. This will open a dialog box that will prompt for the file name of the log file. If the file exists, it will prompt for confirmation to over write the existing file.
- Page 19 5.2.9 - Status Read Back This software will read back the Reversal Switch status regardless of its Local / Remote status. The status read back consists of three interlock indicators and the general status indicators. If any one of the interlock conditions exists, the corresponding indicator will flash on the screen and the DC Power Supply’s output will be disabled.

Page 20: Maintenance
Section 6 MAINTENANCE The 5971-160 Current Reversal Switch should operate for many years without any trouble provided that the following basic maintenance points are observed. Always remember that the AC power should be disconnected before performing any maintenance procedure. The 5971- 160 may generate lethal voltages and must not be operated with damaged components, protective covers or cable insulation. -
