9.2.9.3 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 210)] is active.
