C.1.4 Carry out fault acknowledgement
When serious faults have been quitted, the SPC200 carries
out the initialization and self−test of the connected modules
again. This initialization phase can take a certain amount of
time (max. 10 seconds), depending on the equipment fitted
on the system.
Please note
During this initialization phase no further rising signal edge
may be created at the Start/Reset input.
When a fault has been quitted, there may still be faults (e.g.
hardware faults). In this case, fault acknowledgement should
be repeated up to three times (see sequence plan Fault
treatment"). If the SPC200 is then still not ready to operate
(READY signal = 0), the fault cannot be quitted, as the cause
of the fault must first be eliminated.
A diagnosis can be carried out with WinPISA or with the
control panel.
When the load voltage supply is switched off (e.g. after
Emergency Stop), an appropriate fault message will be disĆ
played. When the load voltage is switched on again, you must
wait 1 second before the fault is quitted (see Fig. C/1 Create
readiness to operate").
