2.9.3. Pump Interlock
Available only on LUT430 (Pump and Flow model), and LUT440 (OCM model).
Discrete inputs allow you to supply pump information to the SITRANS LUT400
so that it can modify pump algorithms. The following parameters are used to
program actions that should take place when a pump is determined to be in a
failed state. For example, a pump interlock can be used to ensure that any pump
reporting a failure is removed from the pumping rotation.
2.9.3.1.
Enables/disables the pump start interlock. If ON, then Pump 1 will not start
if the corresponding discrete input [Pump 1 Discrete Input (2.9.3.2.)] is
active.
Options
2.9.3.2.
Sets the discrete input to use for pump start interlock on Pump 1.
Options
2.9.3.3.
Enables/disables the pump start interlock. If ON, then Pump 2 will not start
if the corresponding discrete input [Pump 2 Discrete Input (2.9.3.4.)] is
active.
Options
2.9.3.4.
Sets the discrete input to use for pump start interlock on Pump 2.

2.10. Data Logging
Use data logging to keep track of a parameter value on regular intervals or when an
event is triggered. Up to 3 data logs can be configured, and collectively the logs can
hold approximately 24,000 entries. [To view these data logs, see View Logs (3.2.6.).]
2.10.1. Logging Mode
Set the behaviour of the data log when full. If First in First out, when new
entries are added, the oldest entry is deleted. If Fill and Stop, when new
entries are added, the logging system stops. .
