7.2.5.1. Timed Filling
The TEC 3000 has several advanced filling options including Timed Filling. Timed Filling
allows the user to set a regular filling schedule based on a fill start time and a fill
frequency. If a facility staff would like the peace of mind of knowing that all the freezers
are full of LN2 before leaving for the weekend, then they could set up a timed fill for every
Friday afternoon. Even if the LN2 level in a freezer is above Low Level Setpoint, the TEC
3000 will initiate a fill and top off the freezer to its High Level Setpoint. If the liquid level is
at or above the High Level Setpoint, then the TEC 3000 will skip that timed fill event and
not initiate a fill.
A TEC 3000 with a Timed Filling schedule will still maintain Auto Fill Control. If Timed
Filling and Auto Fill Control are enabled, then the TEC 3000 will still initiate a fill anytime
the liquid level reaches the Low Level Setpoint. Firmware Ver. 2.03 or higher will allow
the Timed Fill Start to be set to any hour and minutes except midnight.
Timed Filling Setup
Enable Timed Filling and then select the number of days to elapse between timed fillings.
Select a Timed Fill Start time that is later that same day. If Timed Filling is being enabled
at 9:30 AM, then the Timed Fill Start should be set to 9:31 AM or later. This is
recommended for simplicity. The TEC 3000 will initiate a fill when the Timed Fill Start is
reached later that day. From then on, each time the Timed Fill Frequency elapses, the
TEC 3000 will fill the freezer to its High Level Setpoint. The Timed Fill Frequency has a
range of 1 to 28 days and the Timed Fill Start can be set to any hour and minutes except
midnight. If midnight is selected controllers with Ver. 2.03 or higher will automatically
change the hour and minutes to 01:00 hours.
NOTE: Security Level 3 or higher is required to setup or change Timed Filling.
