Variable - actuating variable
The variable corresponds to the extent to which the heater or cooling machine
of the Cryo-Compact Circulator is controlled. Heat or cold is applied to the bath
according to this variable. If this happens with the control electronics of the
Cryo-Compact Circulator , called >control< in this particular case, the bath
temperature is exactly heated and maintained constant at the adjusted
setpoint.
Programming of variables for the parameters > serial < or > eprog < is only
accepted, if the unit is in Start mode.
Possible parameters:
control – The internal control electronics of the Cryo-Compact Circulator
controls the heater and cooling machine. Self-tuning is possible.
serial – The heater or cooling machine receives the control signal via the serial
interface. Self-tuning is not possible.
eprog - The heater or cooling machine receives the control signal via the E-
Prog input. Self-tuning is not possible. (option).
Important:
Set the parameter >EPROG< and the input variables also in the menu
>Inputs/Outputs< (see page 52).
Note:
The E-Prog input can only be used either under menu item >Setpoint<
(page 32) or under menu item >Variable< (see above).
