3.2.4 RESET INPUT CONNECTION
For auto reset mode connect a link across terminals S33 & S34 as shown in Figure 18.
For manual reset mode connect a normally
-
open switch across terminals S33 & S34 as
shown in Figure 19
If the machine has two MPCEs, a pair of normally
-
closed auxiliary contacts from each
MPCE can be connected in series with the reset input as shown in Figure 20. This
provides cross
-
monitoring of the MPCEs such that if they are in disparity due to a
fault, reset will be prevented until the fault is rectified
