Shut-Down
Shut-Down
An external instrument has generated a shut-down signal on the remote line.
The quaternary 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 quaternary
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.
