Pump Interlock (2.9.3.)

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.
Enable Pump 1 (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) (Page 213)] is active.
Options
Pump 1 Discrete Input (2.9.3.2)
Sets the discrete input to use for pump start interlock on Pump 1.
