Dillon FI-90 - Manual (Page 15)

15
A setpoint cutoff is a force-load value at which an internal electrical connec-
tion is broken, causing an external relay to de-energize. Additional relay
configurations can turn on or shut off another electrical device.
You may configure the FI-90 to accept either one of two types of cutoff: (1) a
gross-based setpoint or (2) an increment-based setpoint. A gross-based
setpoint is called, simply, a setpoint. With this type of setpoint, activation of
a cutoff is signaled by a specified gross applied force. You specify, through
the front-panel keypad, the gross force-load setpoint that will activate each
cutoff. For example, suppose your first cutoff requires 100 pounds of force,
and your second cutoff requires 200 pounds of force; you would set the first
setpoint at 100 pounds of force and the second setpoint at 300 pounds of
force, because those values will represent gross force load when the cutoffs
activate.
With the increment-based setpoint, activation of a cutoff is signaled by a
specified amount of net force. You tell the indicator the net amount of force
required to activate each of the cutoffs. Suppose your first cutoff requires 100
pounds of force, and your second cutoff requires 100 pounds of force; you
would enter 100 for setpoint #0 and 100 for setpoint #1.
You can view the type of setpoint that has been configured in your indicator
by looking at the cutoff display in the operations menu. A decimal point
following the word cutoff indicates configuration of gross-based setpoints. If
no decimal point appears after cutoff, the FI-90 is configured for increment-
based setpoints.
1. Starting from either gross mode or
peak-view mode, press MENU
twice to access. . . CutOFF.0 The decimal after CutOFF
says this is a gross-based setpoint.
Then press PRINT / SELECT. . . nn.n is displayed. The n 's represent
the current value in register 0 .

The two setpoint registers are
numbered #0 and #1.
