28 1100 Series Nano Pump Service Manual
2 Troubleshooting and Test Functions
Shutdown
An external instrument has generated a shut-down signal on the remote line.
The nano pump continually monitors the remote input connectors for status
signals. A LOW signal input on pin 4 of the remote connector generates the
error message.
Probable Causes
• Leak detected in another module with a CAN connection to the system.
• Leak detected in an external instrument with a remote connection to the
system.
• Shut-down in an external instrument with a remote connection to the
system.
• The degasser failed to generate sufficient vacuum for solvent degassing.
Suggested Actions
✔ Fix the leak in the external instrument before restarting the nano pump.
✔ Check external instruments for a shut-down condition.
✔ Check the vacuum degasser for an error condition. Refer to the Reference
Manual for the Agilent 1100 Series vacuum degasser.
