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) recovers as soon as the digital input is disabled.
Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
23 WIRING DIAGRAMS
