Displays and sets the high setpoint value for the designated alarm relay. Use this high setpoint function if a relay
operation is required when the display value becomes equal to or more than the low setpoint value.
To set the high alarm value go to the
High
function, press
F
and when you see a digit of the value flash use
the
^
or

push buttons to set the required value then press
F

may be disabled by pressing the
^
and
v
push buttons simultaneously. When the alarm is disabled the display
will indicate
OFF
. If the relay is allocated both a low and high setpoint then the relay will activate when the value
displayed moves outside the band set by the low and high setpoints. The value at which the relay will reset is
controlled by the
HYSt
function.
Overlapping alarms - if the
HiGh
value is set lower than the
Lo
value then the alarm will activate in the band
between the two values.
If the display has annunciator leds for the relay then the annunciator will initially flash in alarm condition, if the
alarm is acknowledged by pressing the
F
button (where fitted) or has been acknowledged by a
P
button or remote
input operation the annunciator will be solidly lit until the display moves out of alarm condition.
Example:
If
High

AL 1
is set to
100
then relay 1 will activate when the display value is
100
