Cleaning Mode 102
19.2. CLEANING BLOCK INPUTS & OUTPUTS
Cleaning block inputs and outputs are common to both Simple and Advanced cleaning.
Inputs common to both types:
• Calendar
` cleaning triggered at specific time and week day. Internal RTC will be used as reference
• Timer
` cleaning triggered at a fix interval. The one second time base interval will be used for that.
• External digital inputs
` cleaning triggered at transition from inactive to active state on one or more digital inputs, provided
the inputs are assigned to do this
• Controller status
` cleaning can be stopped, suspended, or resumed upon controller reaching certain status
• Cleaning enabled
` main condition that allows (or not) cleaning to run
• Sample rate
` timing has the one second time‑base interval used for all time‑sequences evaluation
Outputs are assigned as:
•
Rinse for both Simple and Advanced cleaning where one or more relays are assigned to cleaning, rinse phase.
• Wash for Advanced cleaning where one or more relays are assigned to cleaning, wash phase.
19.3. CLEANING SEQUENCES
Cleaning sequences are specific to each cleaning type and are defined as follows:
Simple cleaning
• Rinse time, the time that Rinse relay is activated
• Recovery time, the time necessary for the probe sensors to reach stable and accurate measurements
Advanced cleaning
• Pre‑Wash rinse time – allocated to sensor rinse before washing
• Wash time – allocated to sensor wash with a washing solution
• Post‑Wash rinse time – allocated to sensor rinse after washing
• Wash cycles number – cycles completed (rinsing and washing solutions)
• Rinse‑Only cycles number – cycles completed (rinsing only solutions)
• Recovery time – necessary for probe sensors to reach stable and accurate measurements
