Typical delay times with the debounce delay switched off
are:
• On-delay for
– I1 to I4: 0.025 ms
– I5 to I12: 0.25 ms
• Off-delay for
– I1 to I4: 0.025 ms
– I5, I6 and I9 to I10: 0.4 ms
– I7, I8, I11 and I12: 0.2 ms
Monitoring of
short-circuit/overload
with CL-LST, CL-LMT and
CL-LET The internal inputs I16, R15 and R16 can be used to monitor
for short-circuits or overloads on an output.
• Display system:
– I16: Group fault alarm for outputs Q1 to Q4
• CL-LET.20DC2:
– R16: Group fault signal for outputs S1 to S4
– R15: Group fault alarm for outputs S5 to S8
h Ensure that input signals are noise-free if the input
debounce is disabled. The display system will even react to
very short signals.
State
Outputs I16, R15 or R16
No fault found 0 = Switched off (N/O contact)
At least one output has a fault 1 = Switched on (N/O contact)
h I16 can only be edited with display system versions with
transistor outputs.
