Programming Set and Reset Points
High alarm indication: program set point above reset point.
Low alarm indication: program set point below reset point.
The deadband is determined by the difference between set and reset points.
Minimum deadband is one display count. If the set and reset points are
programmed with the same value, the relay will reset one count below the set
point.
Note: Changes are not saved until the reset point has been accepted.
Setting Fail-Safe Operation
In fail-safe mode of operation, the relay coil is energized when the process variable
is within safe limits and the relay coil is de-energized when the alarm condition
exists. The fail-safe operation is set independently for each relay. Select
on
to
enable or select
off
to disable fail-safe operation.
Programming Time Delay
The
On
and
Off
time delays may be programmed for each relay between 0 and
999.9 seconds. The relays will transfer only after the condition has been
maintained for the corresponding time delay.
The
On
time delay is associated with the set point.
The
Off
time delay is associated with the reset point.
