Precisely judge the position of multiple fault points, specifically judges that principle is as follows：
Assuming that in control loop the 2nd and the 5th equipment auxiliary contact poor contact or disconnection, then according to above-mentioned detection
The operation principle of system is it is found that the 2nd and the 5th alarm lamp can brighten simultaneously, at this point, relevant staff can be by the 2nd
It is closed with the corresponding reparation control switch repaired in circuit of the 5th auxiliary contact, executes repair action；Simultaneously, it is assumed that the 2nd
To there is also the 4th auxiliary contact poor contacts originally in the 5th auxiliary contact, since the 2nd, the 4th, the 5th auxiliary contact are
Be in series connection, therefore when the 2nd and the 5th auxiliary contact break down, and the both ends of the 4th auxiliary contact are and power supply
It mutually disconnects, thus failure can't be detected, still, when the failure of the 2nd and the 5th auxiliary contact is by " reparation "
Afterwards, the 4th auxiliary contact both ends are connected, then the 4th alarm lamp can brighten alarm at this time, and the 3rd alarm lamp is will not to brighten
, because the 3rd auxiliary contact do not break down, staff can pass through the position judgment fault point that alarm lamp brightens
Position occurs.So far, the detecting system completes the action that multiple fault points are detected and are warned.
