Product:

700er Series Cryostream Cooler

Bus: Serial Line

Class interface


Attributes:

Name Description
GasSetPointScalar: DevFloat Set temperature.
GasTempScalar: DevFloat Current gas temperature.
GasErrorScalar: DevFloat Difference between current and set temperature.
RunModeScalar: DevString RunMode of the cryo controller (StartUp, StartUpFail, StartUpOk, Run, SetUp, ShutdownOk, ShutdownFail).
PhaseScalar: DevString Program Phase of the cryo controller (Ramp, Cool, Plat, Hold, End, Purge, Soak, Wait). This parameter is meaningless unless RunMode is Run.
RampRateScalar: DevUShort Cooling ramp rate for the current program phase.
TargetTempScalar: DevFloat Temperature set point for the current program phase.
EvapTempScalar: DevFloat Current evaporator temperature.
SuctTempScalar: DevFloat Current SUCT temperature.
RemainingScalar: DevUShort Time remaining in current program phase.
GasFlowScalar: DevFloat Current gas flow.
GasHeatScalar: DevUChar Current gas heating.
EvapHeatScalar: DevUChar Current evaporator heating.
SuctHeatScalar: DevUChar Current SUCT heating.
LinePressureScalar: DevFloat Current back pressure.
AlarmScalar: DevString Indicator for most serious alarm conditions.
RunTimeScalar: DevString Uptime of the pump.
ControllerNumberScalar: DevUShort Serial number of the cryostream controller device.
SoftwareVersionScalar: DevUChar Firmware version of the crystream controller device.
EvapAdjustScalar: DevBoolean Evaporator adjusts vacuum compensation.
TurboModeScalar: DevBoolean Turbo mode is active. The gas flow is increased to 10 l/min.

Commands:

Name Description
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
RampInput: DevVarFloatArray
RampRate in K/h (1-360), TargetTemp in K (80 - 400 for standard Cryostream, 500 for Plus and Compact)
Output: DevVoid
Change temperature at a controlled rate. When ramping down in temperature, if the selected rate is too fast for the Cryostream Cooler to follow, the Controller will automatically enter the RAMP / WAIT mode (this will be indicated on the screen). The effect of this is to stop the ramp in order for the gas temperature to catch up to within 5K of the gas temperature.
CoolInput: DevFloat
TargetTemp in K (80 - current temperature, Cools must be downwards)
Output: DevVoid
COOL is designed to get the system as cold as quickly as possible. It uses a flow rate of 10 l/min to draw the maximum amount of liquid out of the Dewar. This is called Machine Turbo and is indicated by the TURBO lamp flashing on and off. Once the system is cold the flow rate will drop to 5 l/min above 90K. To maintain 10 l/min, press the TURBO button so that the lamp remains on permanently.
PlatInput: DevUShort
Duration in min (1-1440)
Output: DevVoid
Maintain temperature fixed for a certain time.
HoldInput: DevVoid
Output: DevVoid
Maintain temperature fixed indefinitely.
PurgeInput: DevVoid
Output: DevVoid
This function is designed to warm up the Coldhead as quickly as possible. It applies maximum power to the three heaters in the Coldhead to get to 300K as quickly as possible. The PURGE is replaced by a SOAK as the heaters run for a further 10 minutes.
EndInput: DevUShort
RampRate in K/h (1-360)
Output: DevVoid
The System will get back to a final temperature of 300K at the given RampRate and then the system is shut down. This is the controlled way to finish an experiment and should be used whenever possible. Once an END function has been programmed, it is not possible to enter any more phases. The only options available are to load or save a program or delete the last phase.
PauseInput: DevVoid
Output: DevVoid
Temporarly hold the temperature fixed until RESUME is send.
ResumeInput: DevVoid
Output: DevVoid
Resume with the current program after PAUSE was send.
TurboInput: DevBoolean
TurboMode (true - on, false - off)
Output: DevVoid
Switch Turbo on or off.
StopInput: DevVoid
Output: DevVoid
Emergency stop, please do not use in normal operation.
RestartInput: DevVoid
Output: DevVoid
Restart a Cryostream which has shutdown.
AnnealInput: DevFloat
Anneal time in s (0.1 - 25.5, 0.0 will open the shutter, -1.0 will close it)
Output: DevVoid
If the device is fitted with a cryoshutter, opens or closes this, permanently or for a defined time period.
