STATION CONTROLLER SC100

VIEW OR CHANGE LEVEL SETTINGS
Menu:
To enter the menu press the Setting Select pushbutton once. To move in the menu from left to
right, press the Setting Select pushbutton again. To exit the menu, press the Setting Select
pushbutton once while at the right most end of the menu.
Viewing Settings:
When the menu indicator over one of the Level Setting potentiometers is on, the current setting will
be shown on the bar graph display.
Changing Settings:
When the menu indicator over one of the Level Setting potentiometers is on, the potentiometer may
be turned to adjust the setting.
Note: The Off setting should be adjusted first, and then adjust the Lead and Lag settings. The
Lead and Lag settings are prevented from being too close to the Off setting. If the Off setting is
moved too close to the Lead and Lag settings, the Lead and Lag settings will be shoved away from
the Off setting and away from what is set on their respective potentiometers.
LEVEL SIMULATION
Entering Level Simulation Mode:
To enter the Level Simulation mode press the Setting Select pushbutton until the “Level Simula.“
menu indicator is turned on. Note that the Level Display bar graph will initially show what the actual
level was prior to entering the Level Simulation Mode.
Changing the Simulated Level:
To change the simulated level, press the Increase or Decrease pushbuttons as desired. The pump
1 and 2 call relays, and the high and low level alarm relays will operate just as though the water
level were actually changing.
Exiting the Level Simulation Mode:
To exit the Level Simulation mode, press the Setting Select pushbutton once. Unless you wish to
view the Level Settings continue to press the Setting Select pushbutton until all of the menu indica-
tors are off. If the controller is left in the Level Simulation mode, a one minute timer will time out
and return the controller to normal operation. The one minute timer is reset whenever the Increase
or the Decrease pushbutton is pressed.

LEVEL DISPLAY
Scale Range:
The Level Display Scale shows level in feet of water. In order for the level to be accurate, the cor-
rect pressure transducer must be used with the controller. The following shows which pressure
transducer goes with the different controllers:
Level Input Calibration:
The analog Level Input on the controller is calibrated at the factory and will not normally need to be
adjusted. If minor adjustments are required, they can be made using the Span and Zero calibration
potentiometers accessible from the front of the unit. When either the Span or Zero calibration is
changed, the other will be affected and should be re-checked and calibrated if necessary, until both
are correct.
Zero Calibration:
First – Use an analog calibration device to apply a 4.0mA signal to the Level Input.
(Alternate Method – Raise the pressure transducer (or bubbler tube) out of the water.)
Next – Adjust the Zero Potentiometer until the lowest bar graph segment is on steady.
Note: The lowest segment will blink when the Zero calibration is too low. It will also blink
if the 4-20mA signal is absent or connected backwards.
Span Calibration:
First – Use an analog calibration device to apply a 20.0mA signal to the Level Input.
(Alternate Method – Place the pressure transducer (or bubbler tube) under a know depth
of water.)
Next – Adjust the Span Potentiometer until the highest bar graph segment is on steady.
(Alternate Method – Adjust the Span Potentiometer until the display reads the known
depth of water covering the pressure transducer (or bubbler tube).)
Note: The highest segment will blink when the Span calibration is too high.
