Electrophoresis cables
are not connected to
the power supply or to
the electrophoresis
unit(s). There is a
broken circuit in the
electrophoresis tank.
Check the connections to the power
supply and the electrophoresis tank to
ensure they are intact; check the
condition of wires in the electrophoresis
unit. Close the circuit by reconnecting
the cables. Press
START/STOP
to
resume the run.
High resistance due to
tape left on a pre-cast
gel; an incorrect buffer
concentration or
volume in the
electrophoresis tank
Ensure that any tape is removed from the
ends of a pre-cast gel, the buffers are
prepared correctly, and the recommended
volume of buffer is added to the
electrophoresis tank.
Error message
Current exceeds the
maximum output for
the power supply
(>400mA)
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.
Error message
Voltage exceeds the
maximum output for
the power supply
(>300V)
Press
the
START/STOP
button
to clear
the error message. Contact Fisher
Scientific’s service department if the
problem persists.
Error message
Thermal limitation of
the power supply
reached (Output
voltage <10V)
(1) Check the connections
(2) If the
Er3
error message persists, the
problem may be caused by internal fan
failure. Contact the
Fisher Scientific’s
service department.
Message
No load is detected
(1) Check the connections
(2) Check the buffer condition / buffer
level
Alarm message
Power exceeds the
maximum output (60W)
