Parameter Description
i1F=dor
Door microswitch Signals that the cold store door has been opened. When the door is opened the
compressor and fans are controlled on the basis of the value of parameter “odc” (see 7.8.5
“Parameters relative to alarms management” ).
After the time set for parameter “did” a door open alarm is generated and the message
“dA” is shown on the display. The alarm terminates automatically as soon as the digital
input is deactivated. Temperature alarms are inhibited when the door is open.
i1F=EAL
External alarm An alarm is generated after the delay set by parameter “did” from activation of the input
an alarm is generated; the message “EA” is displayed and the status of the outputs is not
changed. The alarm switches off automatically as soon as the digital input is deactivated.
i1F=bAL
High pressure switch
alarm (HP)
After a delay set by parameter “did” from activation of the input an shut-down alarm is
generated; the message “CA” is displayed and the control relay outputs are deactivated.
The alarm switches off automatically as soon as the digital input is deactivated.
i1F=PAL
Pressure switch trip If, in the time interval established by the “did” parameter a number of pressure switch
trips is reached equivalent to the number set in parameter “nPS”, the alarm will be
triggered.
The message “CA” is displayed, the compressor is stopped and control suspended.
To resume normal operation switch off the instrument and then switch it on again. When
the input is active the compressor is always stopped.
i1F=dEF Defrost cycle start Function not present
i1F=AUS - Function not present
i1F=FAN - Function not present
i1F=Htr Action reversal Cold- Hot Function not present
i1F=ES Energy Saving function
Function not present
i1P=CL Digital input polarity
The polarity of the digital input depends on parameter i1P
I1P=CL: active with closed contact
I1P=oP: active with open contact
