If the associated sensor is in a fault state (the sensor has failed, there is a wiring/fuse fault or the connector is unplugged), the gauge will show a value of 0.0.  A fault state is indicated by the PLC and the stack light.  If the gauge is not visible (the block is blank), a communication error with the PLC has occurred or a software issue is present on the dashboard PC.  Consult the system administrator.

Note:  The "Nominal Depth" of the surge tank is subject to future revision.  At this time, lacking a proper drain modulating valve, it is not possible to provide "surge" capacity (keep the tank depth lowered during periods of high gutter flow).  As a result, some portion of the "Nominal Depth" and "Excess Depth" is expected when the pool level is high and/or there is a large amount of activity in the pool.  Ideally, the surge tank should usually remain below the gutter inlet level.

When the "Critical Depth" threshold is met, this may result in pump shutdown (per the PLC) to prevent pulling air into the pump.  The surge tank water level is insufficient to maintain operation.  When enabled, auto-fill begins at the upper end of the "Low Depth" threshold and ends when the upper end of the "Nominal Depth" is met.  A large amount of surge tank depth hysteresis is needed when an actual pool depth measurement is lacking.

The tank nears overflow at the "Overflow Depth" threshold.  No specific action is taken by the PLC at this point.
