7.5 CONTROLLER IN NORMAL OPERATION
During normal operation of the K SERIES Cryostorage System the controller display
shows the actual temperature of the thermocouple and the liquid level relative to the
sensors.
Filling takes place automatically to compensate for evaporative losses.
Filling may also be triggered by an external fill signal (Simultaneous Fill).
Once a simultaneous fill input signal has been accepted the controller will not respond
to another simultaneous fill input signal until 30 minutes have elapsed.
This is to avoid the possibility that two or more controllers could interact causing
repeated short fill cycles.
The 30 minute timer may be cleared by resetting the controller as described in section
7.7. This may be useful when testing for correct operation of a system connected for
simultaneous filling.
