limits may be programmed in any test mode.
The HERMIT 2000 will display the
alarm menu. Press

option.
The display will show the limit menu
for input 1 and the current on/off sta-
tus for each limit.
Use the
SCAN
keys to access the limit
menus for other inputs.
Note:
The high and low alarm limits for a dual type input apply
only to the primary value. Dual type temperature does not have alarm
limits.
High Limit
Press
F1
to select the
HIGH
option
from an input’s limit menu.
The on/off status of the alarm limit
is shown in brackets. Press
F1
to turn
the alarm limit
ON
. Press
F2
to turn
the alarm limit
OFF
.
If you turn the limit on, the HER-
MIT 2000 will prompt you for the
high limit. Key in your value for the
high alarm limit and press
ENTER
.
The display will return to the input’s
limit menu with the new on/off sta-
tus updated in brackets.
Enter the high limit in the same units that you have entered other
transducer parameters for the input. The high alarm will activate
when a data point reading is greater than or equal to the high alarm
limit.
Note:
If you have already programmed a low alarm for an input,
the HERMIT 2000 will require that your high limit be greater than
the low limit. The instrument will not accept a high limit entry that
is less than or equal to the low limit entry.
Low Limit
Press
F2
to select the
LOW
option
from an input’s limit menu.
The on/off status of the low alarm
limit is shown in brackets. Press
F1
to turn the alarm limit
ON
. Press
F2
to turn the alarm limit
OFF
.
If you turn the limit on, the HERMIT
2000 will prompt you for the low
limit. Key in your value for the low
alarm limit and press
ENTER
.
The display will return to the input’s
limit menu with the new on/off sta-
tus updated in brackets.
Make certain that you enter the low limit in the same units that you
have entered other parameters for the input. The low alarm will
activate when a data point reading is less than or equal to the low
alarm limit.
Note:
If you have already programmed a high alarm for an input,
the HERMIT 2000 will require that your low limit be less than the
high limit. The instrument will not accept a low limit entry that is
greater than or equal to the high limit entry.
Enabling Alarm Outputs
From the alarm menu, press
F3
to
toggle the alarm output enable.
The current output on/off status is
shown in brackets.
In order to activate the alarm output contacts, the alarm
OUTPUTS
option must be
ON
. If the alarm outputs are off, the HERMIT 2000
will still check alarm limits and display alarm conditions, but the
alarm contacts will not be activated. This feature allows you to test
transducers and alarm functions without triggering devices con-
nected to the alarm output. You can also switch off annoying exter-
nal alarms while the cause of an alarm is being determined and
corrective actions are being taken.
