8.24 EG Stops Operation
• DP/SP power is off
Turning off the DP/SP automatically turns off the EG and the suppressor.
Current to the CR-TC is automatically turned on and off when the EG power
is turned on and off.
Check that the power to the DP/SP is turned on. Prime the pump (see
Section 9.3
) and resume operation.
• DP/SP pressure limit tripped
When a system includes an EG, the high pressure limit for the DP/SP is
21 MPa (3000 psi) and the low pressure limit is 1.4 MPa (200 psi). Check that
the system pressure is within this range.
NOTE The EluGen cartridge requires at least 14 MPa
(2000 psi) of backpressure for optimal removal of
electrolysis gas from the eluent produced by the
cartridge. A system backpressure of 16 MPa (2300 psi) is
ideal.
• DP/SP flow rate is too low or too high
Select a flow rate between 0.1 and 3.0 mL/min.
• Electrical error detected (ALARM LED is lighted)
To prevent damage to the EluGen cartridges, the DP/SP automatically turns
off electrical power to the cartridge when excessive current or voltage is
detected. Contact Dionex for assistance.
NOTE The ICS-3000 Ion Chromatography System electronics
components cannot be serviced by the user.
• EluGen cartridge is expended
Replace the cartridge (see Section 9.12
).
• No communication with Chromeleon or Chromeleon Xpress
1. Check that the
POWER button on the front of the EG is turned on.
2. Check that the EG main power switch (on the rear panel) is turned on.
