alarm delay
Serves to set the time lag before activation of the digital input
alarm
• i1F=EAL or bAL delay between detection and
signalling of an external alarm
• i1F=dor delay on door open alarm signal
• i1F=PAL time for pressure switch operation: if
nPS activations in time did are reached
restarting is manual only by powering off the
unit and then powering it on again
0 255 min. 0
nPS
Number of
pressure switch
activations
At each activation of the digital input the control is blocked; if
nPS activations are reached in time did restarting is manual
only by powering off the unit and then powering it on again.
