5.f. The instrument’s current
LIMITS LATCH MODE status will be displayed:
“ON” or “OFF.” In LATCHING mode (the “ON” state), when a high-limit or
low-limit violation is detected, that violation condition will remain in effect—
regardless of the subsequent behavior of the auxiliary output reading—
until limits are “released” (see Section 5.E for the different ways you can
accomplish this). When limits are NONLATCHING (the “OFF” state), any
detected limit violation condition will cease to occur as soon as the auxil-
iary output reading leaves the corresponding limit zone (or associated
hysteresis deadband).*
Press

state is displayed, press
5.g. Press

LOGIC I/O connections, see Section 2.E).
