User Instructions Low Temperature Freezers Model PRO/XLT

XT111C: the alarm relay status depends on the tbA parameter: with tbA=yES the relay is dis-

abled by pressing any key, with tbA=no the alarm relay remains enabled as long as the alarm

lasts. The display signal remains as long as the alarm condition remains.

Alarm recovery: Probe alarms “PFo”, “PFc” start few seconds after the fault in the probe; they

automatically stop few seconds after the probe restarts normal operation. Check connections

before replacing the probe. Max. and min. alarms “

HA” and “LA” automatically stop as soon

as the variable returns to normal values. Alarms “

bAL” and “EAL” recover as soon as the digital

input is disabled.
