14.1
SILENCING BUZZER / ALARM RELAY OUTPUT
If “
tbA = y
”, the buzzer and the relay are is silenced by pressing any key.
If “
tbA
=
n
”, only the buzzer is silenced while the alarm relay is on until the alarm condition recovers.
14.2
ALARM RECOVERY
Probe alarms
P1
”, “
P2”,
“
P3
” and “
P4
” start some seconds after the fault in the related probe; they
automatically stop some seconds after the probe restarts normal operation. Check connections
before replacing the probe.
Temperature alarms “
HA
”, “
LA
” “
HA2
” and “
LA2
” automatically stop as soon as the temperature
returns to normal values.
Alarms
“EA”
and
“CA”
(with i1F=bAL)
recover as soon as the digital input is disabled.
Alarm “
CA”
(with i1F=PAL) recovers only by
switching off and on
the instrument.
