15.1 SILENCING BUZZER / ALARM RELAY OUTPUT
- tbA=Y: the buzzer and the relay are is silenced by pressing any key.
- tbA=n: only the buzzer is silenced while the alarm relay is on until the alarm condition
recovers.
15.2 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.
