notes:
1. These values are entered in a manual Cal or are calculated from the Auto Cal data; the display reflects
the most recent calibration.
2. These values are blanked out with ‘- - -’ if the most recent calibration entry was a Manual Cal parameter.
3. These values are blanked out with ‘- - -’ if the most recent calibration entry was a Display Value
Correction or the use of the Zero Key.
SeTpoInT Menu [30]
For both relays (#1 - #2) and Digital Outputs (#1 - #6):
The Setpoint Menu is used to enter parameters for relays and digital outputs, review digital output status, and
test relays and digital outputs. This chapter provides explanations of each of the setpoint parameters and
detailed navigation procedures through the menu tree.
31-32 SlcT (SelecT) relay and 33-38 SlcT dIgTl (SelecT dIgITal)
The Descriptions section defines each of the parameters. The Setpoint example section provides an example
with two relays. The Setting Up the Setpoints section provides the procedure for using the SVS2000.
deScrIpTIonS
The relay value is the weight measurement in a vessel where you wish a device (for example, a pump or a valve)
to energize or de-energize. Up to two relays can be set up for the SVS2000.
The digital output value is the weight measurement in a vessel where you wish to control the output. When the
setpoint energizes, the output is driven low. When it de-energizes, the output is driven high. Up to six digital
outputs can be set up for the SVS2000. Refer to TI-SVS-02 for details on use.
The relay and digital output setup functions are similar and are accessed in these menus. They include selecting
energizing levels, high or low energizing, deadband values, preact values, fail-safe parameters, and track mode
for energizing.
Value
Establishes the energizing value, the point where the setpoint changes state. The ‘-’ Key
toggles between positive and negative for the value entered. The default is 0.
Deadband
Determines the point at which a setpoint returns to its normal on/off state after the setpoint
has been energized. Deadband equals the amount of material that will be added to or
removed from the vessel before the setpoint is de-energized. K-M recommends the use of
a non-zero Deadband to prevent setpoints from oscillating. The default is 10, with decimal
point/dummy zeroes consistent with Disp Format.
Hi/Lo
Setpoints can be configured to change state either above (Hi) or below (Lo) the setpoint
value. The default is Lo.
