Introduction

Thank you for selecting a Fisher Scientific FB200 Electrophoresis power supply. This manual describes the operation of the FB200. The power supply that you have purchased is the most productive and easy-to-use unit available anywhere. This manual should answer any questions that might arise in operating your power supply; however, don't hesitate to call our Fisher Lab Equipment Technical Support Hotline at 1-800-943-2006 or 1-800-926-0505 if you need any assistance.

The FB200 power supply is designed to provide constant voltage or constant current output to apparatus used in electrophoresis applications. One to four sets of electrophoresis cells can be connected in parallel and run simultaneously. The FB200 can deliver up to 200W of total output power. When operating in constant voltage or constant current mode, the power supply automatically limits the other parameter to either the power supply maximum, or a lower limit if set by the user. If this non-constant limit is reached, the power supply will automatically switch control modes, from constant voltage to constant current, or vice versa. In this way, the FB200 protects your electrophoresis cells from damaging over power conditions. The FB200 power supply also provides for timed operation in either voltage or current modes, and allows an automatic completion in the event of a power loss if enabled by the user.

Using the Power Supply

Press the dark gray key on the front of the unit to enable/disable the control logic. The LCD display will illuminate and show the values of the last saved run setup. The FB200 preserves the run settings each time you start a run. One set of conditions is saved for each mode, constant voltage or constant current. The setpoint value, limit parameter, time duration, and power-fail restart settings are all saved. This allows convenient setup for repetitive runs.

To change the control mode, press the Exit key. From the resulting screen, select either constant volts or constant amps using the function keys to the right of the display.

After selecting a control mode, either constant voltage or current, and setting the limit and timed run parameters if desired (see Constant Voltage/Current Operations) press the Run key to energize the power supply output. The power supply output will ramp up to the appropriate setpoint, while not allowing the limit parameter to be exceeded. If the limit parameter should be exceeded, then the power supply will crossover control modes, making the limit parameter the new control

FB200-2 MANUAL Page 5 7608175 Rev A 8/02

setpoint. The run mode display shows the controlled parameter highlighted, and will automatically change if a crossover has occurred.

To stop a run in progress, press the Run key, the Stop key, or the gray ON/OFF key. The display will change to "STOP" signifying that the output is no longer energized. To pause a run in progress, press the Pause key. The display will change to "PAUSE" signifying that the output is no longer energized, and that the run can be resumed. Pressing Run or Pause resumes the run from the previous point (i.e. for a timed run). Only a run that has been paused can be restarted. After Stopping a run, or to change parameters of a (paused) run, you must cycle the control logic off and then back on by pressing the gray ON/OFF key.

During a run, the display will show the actual values of voltage and current. The time value displays elapsed time for an untimed run, or time left for a timed run.

Constant Voltage Operations

From the mode selection screen, select constant voltage operation by pressing the appropriate function key located to the right of the display. To get to the selection screen from an operating screen, press Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key. The FB200 will display the last saved values for constant voltage mode. To change a parameter, press the function key located to the right of the display, next to the parameter you wish to change. The FB200 will allow a new value to be entered using the keypad numeric keys. Press the function key labeled "Enter" to complete the new setting. Press Clear to erase previous keystrokes. Press Exit to cancel entering a new value. The FB200 will not accept a voltage setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.

The limit parameter, in this case current, is normally set to the power supply maximum value of

2.00 A. The FB200 will not accept a current limit outside of the allowed range.

In addition, the FB200 will never exceed the maximum power output specification of 200W. When starting a run, the power supply calculates a maximum limit parameter, above which the power supply maximum power output rating would be exceeded. If this value is lower than the limit setpoint entered, the FB200 will automatically lower the limit parameter.

Constant Current Operations

From the mode selection screen, select constant current operation by pressing the appropriate function key located to the right of the display. To get to the selection screen from an operating screen, press Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key. The FB200 will display the last saved values for constant current mode. To change a parameter, press the function key located to the right of the display, next to the parameter you wish to change. The FB200 will allow a new value to be entered using the keypad numeric keys. Press the function key labeled "Enter" to complete the new setting. Press Clear to erase previous keystrokes. Press Exit to cancel entering a new value. The FB200 will not accept a current setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.

The limit parameter, in this case voltage, is normally set to the power supply maximum value of 200 volts. The FB200 will not accept a voltage limit outside of the allowed range.

Timed Operations

It is possible to enter an amount of time for the power supply to provide power, after which it will automatically shut off. Use this feature for timed runs.

FB200-2 MANUAL Page 6 7608175 Rev A 8/02

Enter a time parameter as described above for setting a voltage or current setpoint. Enter a time duration of 0-99 hours, 59 minutes. A time duration of zero effectively disables timed run mode.

When running a timed run, the time parameter displays the time remaining in the run. When running a non-timed run, the time parameter displays the elapsed time during the run

Automatic Power-fail Restart

Automatic power-fail restart capability allows a timed run which is interrupted by loss of AC power to be restarted automatically, so that the total time programmed for the time parameter will be met. NOTE: Loss of AC power includes switching off the unit using the power switch located at the rear of the unit. When performing timed runs with power-fail restart enabled, always use

the front panel controls to stop a run in progress.

To enable power-fail restart, press the top function key when in the operating mode screen (constant voltage or current). The state of power-fail restart will toggle from off to on or on to off with each keypress.

When AC power is restored during a timed run in which power-fail restart is enabled, the display will show "POWER-FAIL RESTART" for approximately 10 seconds indicating power-fail restart pending. During this time the output is not energized, to allow safely stopping the run (by pressing Run). After the power-fail restart pending delay is completed, the power supply output will ramp up to the setpoint value and the time will continue from that point. Any number of power interruptions can occur during the completion of a single run.

Cleaning

Before cleaning the unit, be sure to always turn off AC power using the switch at the rear of the unit, and then disconnecting the AC line cord. The front of the unit is sealed and can be wiped clean with any mild detergent solution. Avoid harsh cleaners or agents as they may deteriorate the surface of the tactile membrane keys.
