Timed Operations; Volt-Hour Operations; Automatic Power-Fail Restart - Fisher Scientific FB3000-2 Manual De Instrucciones

Note
Loss of AC power includes switching
off the unit using the power switch
located at the rear of the unit.
When performing timed or volt-hour
runs with power-fail restart enabled,
always use the front panel controls
to stop a run in progress.

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.
Set up a constant mode setpoint and limits as described
above. 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.

Volt-Hour Operations

It is possible to enter an amount of volt-hours for the
power supply to provide power, after which it will automati-
cally shut off. Volt-hours is the integration of voltage over
time. Use volt-hour control to provide consistency
between runs.
Set up a constant mode setpoint and limits as described
above. Enter a volt-hour duration of 0-9999 volt-hours. A
volt-hour duration of zero effectively disables volt-hour run
mode.
During a run, the volt-hour value displays the accumulated
volt-hour value for the run.

Automatic Power-Fail Restart

Automatic power-fail restart capability allows a timed or
volt-hour run which is interrupted by loss of AC power to
be restarted automatically, so that the total time/volt-hour
programmed for the run will be met.
To enable power-fail restart, press the top function key
when in the mode selection screen (MANUAL or PRO-
GRAM). 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 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
