Parameter Values Comment
Pt0/1) Set bit 0 for Pt0 or bit 1 for Pt 1 in the attribute that is associated with the selected
control.
The 1444 DYN04-01RA includes two discrete TTL class input channels.
These let users physical wire an input to the module that can be used in
any of several described manners.
Function Description
Trip Inhibit/ Bypass Inhibits trips with all voted alarms
that define the Logical Input as its
control
Alarm/Relay Reset Resets all latched voted alarms
where the alarm condition has
cleared, which resets any associated
physical relays.
Voted Alarm SPM Control Manages Setpoint Multiplication
for measurement alarms that are
inputs to the associated voted
alarm.
Voted Alarm Gate Control Manages Alarm Gating for the
associated voted alarm.
Voted Alarm Logic Control Use this to wire an external input
that, when actuated, forces the
associated Voted Alarm to actuate,
and therefore any relays associated
with it. See I/O Control on the Voted
Alarm page for further information.
Speed 0 Fault If wiring a TTL tacho source to the
terminal base, rather than via the
local bus, this input can be used to
communicate the tacho channel
status.
Speed 1 Fault
