5.8.5 Pharma Warning and Fail Signal
The Pharma 1 warning limit is entered from the op-panel for stage 1 and is user
selectable. The digital output “Pharma n Warn” is available (See Digital Source Selection
- Table 6-4).
The Pharma Fail signal is generated whenever any of the following conditions are met:
Stage 1 – Measured Conductivity exceeds 100%
Stage 1 – Temperature not within range of 0-100 degrees C
Stage 2 – Conductivity is 0.1 µS/cm or greater for 5 minutes
Stage 3 – pH not within range of 5 – 7pH
Stage 2 and 3 – Temperature not within range of 24 – 26 degrees C.
The digital output “Pharm n Fail” is available (See Digital Source Selection - Table
6-4).
When the Stage 2 or Stage 3 test is successful, the fail signal is cancelled and the Pharma
Timer begins to count down from the timer minutes value that was configured. When the
Timer countdown is completed, the Pharma function block returns to Stage 1. A fail
signal will return if measured conductivity exceeds 100% or warn signal if measured
conductivity exceeds Pct Warning value.
See Section 12.5 for Pharma Fail Messages.
