Status

These properties apply to the mover and inventory configuration.

Property

Description

ChargerStatus

Displays the status of the Charger which is related to the connection state, as well as to the mover state:

  • Disconnected (the device is not connected)

  • Idle (the mover is idle)

  • Busy (the mover is performing a movement)

  • DoorOpen (the door is open)

  • InventoryScan (the mover is running an inventory scan)

  • Unpowered (the motors are disconnected from the power supply, most likely because of an emergency stop – other cases in which the motors are not powered are covered by the stages DoorOpen and Error)

  • Error (the mover is in an error state)

ErrorState

Displays the error state of the Charger.

 Tip: Check the audit trail.

OrientationAlert

  • On: One or more racks/well plates are not oriented correctly in the Charger shelf.

  • Off: All racks/well plates are oriented correctly in the Charger shelf.

 Note:

If a rack/well plate does not have a barcode, or if there is no rack/well plate identified because the shelf level is empty, this property will always be set to Off, even if the rack/well plate is not oriented correctly.

RackInSampler

Indicates whether or not one of the racks in the Charger has temporarily been placed into the autosampler due to a pending injection:

  • If the carousel segment or shelf level is empty, or the rack/well plate is located in the Charger, this property will be set to No.

  • If the rack was preliminarily moved into the autosampler, this property will be set to Yes.

RackInTransfer

Indicates if a rack is currently being transferred from the Charger to the autosampler or vice versa: Yes or No.

TriggerInventoryScan

Initiates an inventory scan.

 

Mover

Command

Description

AtSafePosition

Indicates whether the current location of the mover is ‘safe’, i.e. whether one can remove the shelf and rotate the sampler carousel.

Busy

Indicates whether the mover is currently in operation.

Door

Displays the status of the door.

IsPowered

Displays whether the mover motors are powered or not.

Motor

Switches the motor power on or off.

Note:

The motors are switched off automatically when the door is opened. There is no need to power them immediately after the door has been closed, the motors will be re-powered automatically.

PlateOnShovel

Indicates whether the mover has a well plate or rack on its shovel.

Save

Moves the swivel arm of the mover back to a safe position.

Stop

Disconnects all motors from the power supply. Consequently all ongoing movements, for example a running batch, are aborted and pending movements are discarded.

 

Temperature

Command/Property

Description

MaxTemperature

Displays the actual maximum temperature of the Charger after the latest reset of the temperature history. See also ResetTemperatureHistory.

MinTemperature

Displays the actual minimum temperature of the Charger after the latest reset of the temperature history. See also ResetTemperatureHistory.

ReadyTempDelta

Indicates the maximum allowed deviation between the nominal temperature and the actual temperature. If the actual temperature deviates from the nominal temperature by more than the maximum allowed deviation, the Charger is not ready to operate (TempReady reports NotReady). If set to None, Chromeleon does not check whether the actual temperature deviates from the nominal temperature.

ResetTemperatureHistory

Resets the temperature history, so that MinTemperature and MaxTemperature are set to the current temperature. The temperature history logs minimum and maximum temperatures of the Charger since the last reset.

TempCtrl

Displays if the temperature control of the Charger is enabled: On, Off.

Note:

This property can only be set via the TempCtrl property of the autosampler.

Temperature.Actual

Displays the actual temperature of the Charger.

Temperature.Nominal

Displays the nominal temperature of the Charger.

Note:

This property can only be set via the Temperature.Nominal property of the autosampler.

TemperatureError

Displays whether the thermostatting unit of the Charger is in an error state: Ok, Error.

TemperatureReady

Displays whether the thermostatting unit of the Charger is in an equilibrated state. The value depends on ReadyTempDelta. If TempCtrl is Off, TemperatureReady always reports Ready.

TemperatureStatus

Displays the status of the thermostatting unit of the Charger: Unknown, Cooling, Heating, AtSetPoint, Error.
