Figure 6.4: DIL switches for setting mode
Tables 6.1 and 6.2 show details of the modes available and the switch settings required to obtain them.
For ease of access, it is recommended that switches are set to the required mode before installation.
Table 6.1 indicates whether the output follows the input, or the output is the reverse or antiphase of
the input.
For example, in mode 0, o/p 1 = chA; so, if channel A switch is closed, then output 1 will also be
closed or short circuit. However, in mode 1, o/p 1 = chA rev., so if channel A switch is closed, then
output 1 will be the reverse, i.e. open-circuit.
Table 6.2 shows the MTL5510B modes. The logic tables and timing diagrams on the following
pages provide more detailed information on these modes.

MTL5510 & MTL5510B diagnostics
If an internal fault is detected, all outputs and channel LEDs will turn off and the red Fault LED
will turn ON.
