Delay times for Pico AC Units (1760-AWA, -L12AWA-NC,
-L12AWA-ND, -L18AWA)
The input delay with AC voltage signals depends on the frequency:
• On-delay:
–
––
– 66 ms at 60 Hz, 80 ms at 50 Hz
• Off-delay:
–
––
– I1 to I6 and I9 to I12: 66 ms at 60 Hz, 80 ms at 50 Hz
–
––
– I7 and I8: 150 ms at 60 Hz, 160 ms at 50 Hz (1760-L12AWA-xx)
–
––
– I7 and I8: 66 ms at 60 Hz, 80 ms at 50 Hz (1760-L18AWA)
If the delay is switched on, Pico checks at 33 ms (40 ms for 50 Hz) intervals
whether there is a half-wave present at an input terminal (1st and 2nd pulses in A).
If Pico detects two pulses in succession, the device switches on the corresponding
input internally.
If this is not the case, the input is switched off again as soon as Pico does not detect
two successive half-waves (1st and 2nd pulses in B).
If a button or switch bounces (A), the delay time may be extended by 33 ms at 60
Hz (40 ms at 50 Hz) (A).
If the input delay is switched off, the delay time is reduced.
• On-delay
–
––
– 16.6 ms at 60 Hz, 20 ms at 50 Hz
• Off-delay:
–
––
– I1 to I6 and I9 to I12: 16.6 ms at 60 Hz, 20 ms at 50 Hz
–
––
– I7 and I8: 100 ms at 60 Hz and 50 Hz (1760-L12AWA-xx)
–
––
– I7 and I8: 16.6 ms at 60 Hz, 20 ms at 50 Hz (1760-L18AWA)
