MTL5510B modes
The following logic and timing diagrams are provided to assist the user in understanding the behaviour of the MTL5510B module
when a specific mode is chosen.
The open switch ( ) and closed switch ( ) symbols are used to represent both the input conditions of Ch A, Ch B, Ch C or Ch
D and then the output conditions of o/p 1, 2, 3 or 4. Note that in certain modes a Line Fault can cause an override of the output.
How to use these mode tables - examples
The logic tables for Mode 1 represent Ch A controlling outputs 1
& 3, while Ch C controls outputs 2 & 4.
Output 1 & 3 are shown following input Ch A (open or closed)
while Outputs 2 & 4 follow input Ch C.
Mode 2 however shows o/p 1, 2, 3 and 4 being in antiphase
to their inputs.
Mode 9 operates with both outputs for each channel being
in antiphase to their inputs.
