Leak Condition Source (see Section 2.1, Fig. 2.1)
If a leak detect source is used, a leak detect output from that device can be transmitted to a C1900
Dairy Pasteurization unit. This allows the unit to divert flow via a second back-up/divert valve fitted
in series with the first valve. If a divert event is required, digital input 1.2 must be used and
Src
must also be set to digital input 1.2.
Divert Set Point 1
Set the temperature for divert set point 1.
Divert Hysteresis Point
Set the hysteresis value required in engineering units (common to all set points).
Note. Only activated on values above the divert set point temperature.
Time Hysteresis
Set the time hysteresis value required between 0 and 9999 seconds (common to all set points).
Note. If product temperature reaches the set point value, forward flow is initiated
t-hyst seconds after reaching that value. If the temperature drops below the setting in the Divert
Set Point display, flow is diverted immediately.
Hot Water Set Temperature 1 (Model 1952 and 1953 only)
Set the hot water control temperature set point for divert set point 1, used in conjunction with
associated divert number 1.
Set Point Source 1
Select the digital source to engage set point 1.
Divert Set Point 2
Set the temperature for the required divert set point 2, used in conjunction with associated divert
number 2.
Hot Water Set Temperature 2 (Models 1952 and 1953 only)
Set the hot water control temperature set point for divert set point 2, used in conjunction with
associated divert number 2.
Set Point Source 2
Select the digital source to engage set point 2.
Repeat the above procedure for additional Divert Points, Hot Water and Set Point Sources.
Up to 8 individual Divert Points can be set, each has an associated Hot Water and Set Point
Source.
Note. The Hot Water Set Temperature facility is not available with model 1951.
Forward/Divert Indicator Color
