6. PARAMETER DESCRIPTION
[G13: High High Alarm] High-high alarm setting
This parameter sets the high-high limit (HH) alarm
value, and this is done using a % value of the maxi-
mum span.
᭹ A setting value of 110% indicates that the alarm is
disabled.
NOTE
Setting of -110% or 110% results in the corre-
sponding function being disabled; accordingly,
settings can be combined to implement only high
alarms or low alarms, etc.
Output Example 1
The high-high alarm (HH) is set to 90% or more of the
flow rate span; the low-low alarm (LL), to 20% or less;
the high alarm (H), to 80% or more; and the low alarm
(L), to 30% or less.
Settings are:
G10: Low Alarm = 30%
