Variable - actuating variable
The variable corresponds to the extent to which the heater or cooling machine
of the circulator is controlled. Heat or cold is applied to the bath according to
this variable. If this happens with the control electronics of the circulator, called
>control< in this particular case, the bath temperature is exactly heated and
maintained constant at the adjusted set point.
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 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).
ImportantImportant:
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
