A 20-breakpoint (custom) linearizer. Custom linearizers can be applied to any analog
input by selecting them as the linearizer type for that input – see page 31. The
engineering range and units of the input source are assigned to the custom linearizer
output.
Selects the input source to be linearized – see page 76 for description of sources.
Set X and Y values as a % of the engineering range input source.
Selects the breakpoint to be configured.
X is input to the linearizer expressed as a % of the electrical range.
Y is output expressed as a % of the engineering range.
Once configured, a custom linearizer must be soft-wired to an input or output using the custom
template feature – see Section 7.1, page 22.
Two delay timers are provided. Each is triggered by the rising edge of its assigned source. An internal
timer is started and, when the timer reaches the set Delay Time, its output goes high for the On Time
that is configured. After the delay time is triggered it ignores further transitions of the source input until
the end of this delay timer cycle (until end of On Time).
The source signal used to trigger the delay timer. Trigger occurs on rising edge of the signal – see
Appendix A, page 76 for description of sources.
The delay (in seconds) between the trigger received and the output of the delay timer going high.
The amount of time (in seconds) the delay timer output is held in the high state.
