Phase Template: cip-conductivity-check¶
Measure residual conductivity and evaluate against an acceptance limit. Used at the end of a CIP rinse cycle to verify that detergent residues have been rinsed out. The phase always completes. It records a PASSED or FAILED operator message and advances regardless of the result. Acting on a failure (re-rinsing, holding for operator review) is a decision for the operation level or the operator. This phase decides nothing.
Where to find it¶
System endpoint → Equipment Library → Phases → cip-conductivity-check.
Parameters¶
| Parameter | Type | Unit | Range | Default | Required |
|---|---|---|---|---|---|
conductivity_limit |
REAL | µS/cm | 1.0-100.0 | 15.0 |
yes |
The template also declares one output: measured_conductivity
(REAL, µS/cm). It is the conductivity PV captured at measurement time,
so the batch production record can show the acceptance limit alongside
the measured value.
Required control modules¶
| Role | Module type | Description |
|---|---|---|
conductivity_sensor |
analog-sensor | Conductivity measurement for CIP endpoint verification |
Capability¶
mixing
Used in¶
This is a building block, called by the
cip-conductivity-rinse-op operation
template at the end of each rinse pass.
Failure modes¶
This is a PV-endpoint phase. See Phases → PV-endpoint phase for the full archetype.
Pairs with a TagHigh alarm on absolute conductivity. Set a timeoutSeconds on the phase as a backstop.
