LOCAL ALARMS, INDICATORS AND READOUT
The LubriMist® Model IVT is equipped with sensors, which monitor different operating functions
for the Main Oil Mist Generator. The operating status of each of these operating functions is
enunciated in several different ways. These are:

The signal from the level switch and nine standard / two optional sensors is fed into conditioning
circuits of the controller. The conditioning circuit signal is interpreted and scaled by the program
to produce gauge values. See "Reading Unit Operating Conditions" on how to check operating
conditions.
The program performs an ordered series of control set point checks for the maximum and
minimum values of each monitored function. If the current value exceeds a maximum setting
(high alarm) or is less than a minimum setting (low alarm), the IVT controller recognizes the fault
condition and locally identifies the alarm.
The Model "IVT" locally identifies and indicates a fault condition in three ways. They are:
1) individual panel indicators, 2) fault message readout on the liquid crystal display and, 3) red
and green externally mounted unit status lights.
