High voltage
application set to run
on a very low current
The no load alarm on the display screen
needs to be disabled. Contact Fisher
Scientific to arrange return of power
supply for the appropriate circuit board
modification to be made. There may be
cost for this.
Err1
Error message;
power supply stops;
alarm sounds
Current exceeds the
maximum output for
the power supply
(>700mA)
Check if the buffer concentration or
molarity is appropriate. Excessive buffer
concentration or molarity may increase
conductivity. To clear the error message,
press the
START/STOP
button.
Err2
Error message;
power supply stops;
alarm sounds
Voltage exceeds the
maximum output for
the power supply
(>300V)
Press
the
START/STOP
button
to clear
the error message. Contact Fisher
Scientific if the problem persists.
Err3
Error message;
power supply stops;
alarm sounds
Ground leak detection (1) Check the electrophoresis system for
earth leakage
(2) If the
Err3
error message persists,
switch the power on/off and restart the
application.
Err6
Error message;
power supply stops;
alarm sounds
Power supply is
over-heating
(1) Turn off the power supply immediately
and check that there is sufficient
clearance around the power supply for
ventilation.
(2) If the
Err6
error message persists and
the power supply cannot be restarted
disconnect it from the mains and contact
Fisher Scientific.
Err7
Error message;
power supply stops;
alarm sounds
Poor connection
between power cable
and power supply;
damaged power cable
or electrode
Check the power cables and electrodes
within the gel tank.
