Behaviour in the event of a short-circuit/overload
Should a short circuit or overload occur on a transistor
output, this output will switch off. The output will switch
back on up to the maximum temperature after a cooling time
that depends on the ambient temperature and the current
level. If the fault condition persists, the output will keep
switching off and on until the fault is corrected or until the
power supply is switched off (
a
section “Monitoring of
short-circuit/overload with CL-LST, CL-LMT and CL-LET”,
page 376).
Connecting the analog
output CL-LDR.17DC2 und CL-LDT.17DC2 are each provided with
one analog output QA 01, 0 V to 10 V DC, 10-bit resolution
(0 to 1023). The analog output allows you to control servo
valves and other final controlling elements.
Caution!
Analog signals are more sensitive to interference than
digital signals. Consequently, greater care must be taken
when laying and connecting the signal lines. Incorrect
switching states may occur if they are not connected
correctly.
