MPA2C3 User Manual 79
Reaction Specifies the input, output, or output group that will react to a change of state
from the trigger point. Use the drop-down list to specify the number of the input
or output.
Interlock Actions Then Execute (Alarm Action) – Specifies the reacting component’s action
when the trigger’s change of state occurs. Select the action from the available
options.
Upon Resuming (Normalcy) – Specifies the reacting component’s action
when the trigger returns to the normal state. Select the action from the available
options.
Following are the available Input Reactor actions in the drop-down lists:
Unshunt – Reactivates the input point.
Shunt – Ignores alarms from the input point.
Follow – The reacting point (second point) takes on the same state as the
triggering point (first point).
Invert Follow – The reacting point (second point) takes on the opposite state
as the triggering point (first point).
No action – The reacting point (second point) does nothing in response to the
state change of the triggering point (first point). No change of state.
Timed Shunt – Ignores alarms from the input point for a specified amount of
time.
Following are the available Output Reactor actions in the drop-down lists:
De-energize – Remove energy from an output point or group. On a system,
the normal state of an output point or group is "de-energized".
Energize – The state of an output point or group. Output points and groups
are in a normal state when they are "de-energized". An energized state means
that the output or group is active.
Follow – The reacting point (second point) takes on the same state as the
triggering point (first point).
Invert Follow – The reacting point (second point) takes on the opposite state
as the triggering point (first point).
No action – The reacting point (second point) does nothing in response to the
state change of the triggering point (first point). No change of state.
Pulse – Energizes the output point or group for a specific amount of time.
Pulse Off– Becomes unshunted for the programmed shunt time, followed by
a return to the shunted state.
