Message and Code Description 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. Open the purge valve if it is not yet open.
2. Check the flow path for indications of blockage. See also
Code 4098 Upper pressure limit exceeded .
3. Take appropriate remedial action as necessary.
4. Mute the alarm by pressing the MUTE ALARM button on the
pump keypad.
5. Start a new purge cycle.
Code 4101 Not ready. Please run self-
test. The pump is not ready because the self-test was not successful.
Perform the following sequence of steps:
1. Open the purge valve.
2. Repeat the self-test.
3. Close the purge valve.
Code 4112 Self-test failed because of
fluctuating pressure. Changes in pressure have occurred during the self-test. Perform
the following sequence of steps:
1. Open the purge valve.
2. Repeat the self-test.
3. Close the purge valve.
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.
1. Open the purge valve.
2. Repeat the self-test.
3. Close the purge valve.
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 is running.
Retry after 1 minute. If the message appears again, perform the
following sequence of steps:
1. Open the purge valve.
2. Repeat the self-test.
3. Close the purge valve.
Code 4115 Working piston pressure zero
out of range. The message may appear for the pressure sensor in a pump head
or for the system pressure sensor:
• If the message appears for only the right pump block or the left
pump block, the cable for the pressure sensor in the pump head
may not seat properly in the
P-WORK connector.
• If the message appears for both pump blocks at the system time,
the cable for the system pressure sensor may not seat properly
in the
P-SYS connector.
Verify that the pressure sensor cable is properly plugged into the
connection port and retry. If the problem persists, contact
Technical Support.
