Safety Flap Missing

Error ID: 4032
The safety flap was not detected.
Before the needle moves down into the needle seat to inject sample, the safety
flap locks into position. Next, the gripper checks the safety flap by trying to
move the safety flap away from the needle. If the gripper is able to move
beyond the safety flap position (safety flap not in position), the error message
is generated.

Valve to Bypass Failed

Error ID: 4014, 4701
The injection valve failed to switch to the bypass position.
The switching of the injection valve is monitored by two microswitches on the
valve assembly. The switches detect the successful completion of the valve
movement. If the valve fails to reach the bypass position, or if the microswitch
does not close, the error message is generated.
