Transducer Block Parameters - YOKOGAWA vigilantplant EJA Series User Manual

PV_FTIME:
Sets the time constant of the damping function
within AI block (primary delay) in seconds.
OUT_SCALE:
Sets the range of output (from 0% to 100%). The
unit can also be set with ease.
Alarm Priority:
Indicates the priority of the process alarm. If a value
of 3 or greater is set, an alarm is transmitted. The
factory default is 0. Four types of alarm can be set:
HI_PRI, HI_HI_PRI, LO_PRI, and LO_LO_PRI.
Alarm Threshold:
Sets the threshold at which a process alarm is
generated. The factory default setting is a value that
does not generate an alarm. Four types of alarm can
be set: HI_LIM, HI_HI_LIM, LO_LIM, and
LO_LO_LIM.

5.6.5 Transducer Block Parameters

The transducer block sets functions specific to the
measurement of the differential and normal pressure of
the EJA. For a list of the parameters of each block of
the EJA, refer to "List of parameters for each block of
the EJA" in Appendix 1. The following is a list of
important parameters with a guide to how to set them.
TERTIARY_VALUE:
Displays the capsule temperature of the EJA.
TERTIARY_VALUE_UNIT:
Sets display unit of temperature at EJA. If set to
1001, C is used, and if set to 1002, F is used. The
factory default setting is C.
DISPLAY_MODE:
Sets the unit to be used for LCD display.

DISPLAY_CYCLE:
Sets the cycle of LCD display in units of function
block execution cycles. The factory default setting is
1, but if a low temperature environment makes it
difficult to view the display, it is recommended that
you set a longer display cycle.
