All the alarm signals (red LED, alarm relay, fault currents)
are suspended while in hold mode (the correspondent er-
ror events are not closed), unless the hold mode is being
triggered by one or more errors and no other trigger source
(different from an error) is active .
The analog output follows these rules:
• if it is configured for control (i .e . setup item O .10 or O .20
set to “SEt”), its value is set to the minimum (e .g . 4 mA
for 4-20 mA output);
• if it is configured for a recorder, its value is either set to a
user-selected value through the setup item O .15 or O .25
(when item O .14 or O .24 is set to “USEr”) or frozen to
the last value, i .e . the output value just before entering the
hold mode (when item O .14 or O .24 is set to “HOLd”) .
After the cause which made the instrument enter the hold
mode expires, the device exits hold mode but control
and alarms remain disabled for a delay which can be
user-selected (0 to 99s) through setup item C .70 . In that
situation measurements are normally acquired, displayed
and recorded through the analog output or the RS485 .
Note
Alarms (red LED, alarm relay, fault currents) are not disabled
if the hold mode is being triggered by an error and no other
trigger source is active .
