{ Note. The Set Point 2 menus continue from here, and are
structured in the same manner.}
SET POINT SOURCE
The set point operation on the MOD53 can be configured to operate from one of
three sources. The default source is the main sensor input reading, but the set
point can also trigger from the temperature input or be used to switch a cleaning
device for timed washing of the sensor. The menu structure for configuring the set
points is basically the same for the sensor and temperature inputs. For cleaning
operation, the menu items are replaced by the cleaning menu.
SET POINT TRIGGER
The set points can be configured to trigger in four ways. The level where the set
point triggers is set by editing the value under the “Set Point 1” menu item in the
“Set Points” menu. When the trigger is set to Band or Latch the “Set Point 1”
menu disappears and “SP1 Band High” and “SP1 Band Low” menu items become
available.
1. When the Trigger is set to “High”, the relay will be activated when the source
input becomes greater than the set point.
2. When the trigger is set to “Low”, the relay will become activated when the
source input is less than the set point.
3. When the trigger is set to “Band” the relay will become activated when the
source input is either greater than the “Band High” level, or lower than the “Band
Low” level.
