Setup relays
Select yes to enter the relay menu and set up the relay
parameters.
DEFAULT No
Relay1
The relays can be used either for a high alarm or a low alarm. A
high alarm has its reset below the set point, and a low alarm
has its reset above the set point. The relays can also be set up
to have pump cycling enabled.
DEFAULT Off
Channel
The channel to which the relay corresponds.
DEFAULT ONE
Set point
This is the value where the relay will set.
DEFAULT 1.65 ft
Reset point
This is the value where the relay will reset.
DEFAULT 1.65 ft
Pump cycle
Select the type of pump control that is required. The LST400
has two pump cycling routines which can be used to efficiently
distribute the run cycles between various pumps that serve a
common purpose. The ROTATE pump routine will use the relay
set points configured for the pumps that require cycling, and
rotate these set points among the pumps with the
COMPLETION of each cycle. NOTE: The COMPLETION of a cycle
is reached once all pumps have switched OFF.
The FIFO (First In First Out) routine will use the relay set points
configured for the pumps that require cycling, and rotate these
set points among the pumps for subsequent cycles.
NOTE: The FIFO routine ensures that the lead pump will always
switch off first.
HINT: It is advisable to configure the reset points for the pumps
that require cycling to the same level.
DEFAULT Off

Clears the number of cycles as well as the run hours recorded
for the particular relay specified.

Setup lineariser
This prompt will allow you to input a curve to linearise the
vessel. The span is divided by 21 and you can input the new
height for each point as well as the corresponding percentage
fill at that point. LST400 prompts you at each point.
DEFAULT No
Activate lineariser
This function activates the lineariser.
DEFAULT No
Set point
This is the number at which point the user is inputting a
linearized point.
Height/percentage
Height is the distance from the bottom of the tank to a
corresponding point where a suitable percentage can be
determined.
DEFAULT 0.00 ft
Enter the percentage volume of vessel at a corresponding
height.
DEFAULT 0.00 %
