Ringback Sequence
This mode uses visual and audible signals to indicate that the alarm has returned to normal and the
operator can reset the alarm. When an alarm contact returns to normal the ringback circuit will pulse
the audible alarm and the associated LED will flash at approx half the speed of the normal alarm flash
rate. Ringback operation may be used with all but non-latched and auto reset sequences and operates
in the same way for all first-up sequences F0 to F2.
Two Pushbutton Operation
In certain circumstances using remote pushbuttons, it may be desirable to use only two pushbuttons:
Reset and Lamp Test. The Reset pushbutton is used to Acknowledge an alarm if the contacts are in
the alarm condition and to Reset it if the contacts are clear.
Status Only Operation
In applications where the user wishes to indicate the current status of plant machinery the channel can
be set to status only. In this Mode the associated LED will be either on or off as the Input changes
state
. Example :- alarm normal = PUMP ON : alarm abnormal = PUMP OFF. Please note:- This feature
is only selectable in pairs ( Channel 1 & 2 or Channel 3 or 4 ).
Please refer to the last page of the manual for details of the switch settings required for each of the
following sequences
