Alarms - JUMO eTRON M 100 Notice De Mise En Service

2009-04-10
Parameter Meaning
Fan run-up delay after defrosting (Fan deLay)
After defrosting, the activity of the fan relay will be delayed for the time that was set.
This has a higher priority than the run-up delay activated through F.ru=on, which
would possibly switch the fan on earlier.

5.6 Alarms

Requirements for Alarm signaling:
After power ON, the temperature of the cold store must have been in the "OK range" at least once, before an alarm is signaled
and output as a result of a temperature transition from the "OK range" to the "alarm range".
In the example for absolute alarm limits AL.F=0 (see next page), the temperature of the cold store after power ON would have
to lie between 6°C and 94°C once, before an alarm message is output when the alarm limits are infringed (out-of-limit).
Probe break or probe short-circuit:
An alarm is also initiated when a probe break or a probe short-circuit is established at the input for the cold store temperature.
AL.Q and AL.d take effect here.
Alarm signaling is inactive during defrosting (Relay
