Message and Code Possible Cause and Remedial Action
Code 4100 Purge pressure limit
exceeded. A pressure of more than 5 MPa built up after a purge cycle has started.
Perform the following sequence of steps:
1. On the purge unit, remove the capillary from the system pressure sensor.
2. To absorb liquid leaving the capillary, place a tissue under the purge unit and
capillary.
3. Mute the alarm by pressing the
Mute Alarm button on the pump keypad.
4. Start a purge cycle.
If the message does not appear again:
The purge unit is defective. Contact Technical Support.
If the message appears again:
1. The capillaries that connect the system pressure sensor to the purge unit are
blocked. Replace the capillaries.
2. If the message appears again afterward, run a self-test.
3. If the message persists, contact Technical Support.
Code 4101 Not ready. Please run
self-test. The pump is not ready because the self-test was not successful. Repeat the self-
test.
Code 4112 Self-test failed
because of fluctuating pressure. Changes in pressure have occurred during the self-test. Wait until the system
pressure is down or depressurize the system and repeat the self-test.
Code 4113 Self-test failed
because pressure is out of range. The pressure has not been down to zero during the self-test. Verify that the
pressure sensor cables are properly connected. Wait until the system pressure is
down or depressurize the system and repeat the self-test. If the message
appears again, the system pressure sensor may be defective. Contact Technical
Support.
Code 4114 The device is busy.
Please retry after 1 minute. The pump is not ready because, for example, a self-test or recalibration
procedure is running. Retry after 1 minute. If the message appears again, wait
until the system pressure is down or depressurize the system and turn the
pump off and on again.
Code 4119 Can't start pump
while alarm is on. An alarm is present, for example, because leakage has been detected. You can
restart the pump flow only when the alarm is no longer present. Mute the alarm
by pressing the
Mute Alarm button on the pump keypad. Find and eliminate the
source for the alarm as suggested for the accompanying message.
