SHIFT (shift output)
The SG2 smart relay includes only one SHIFT coil that can be used throughout a program. This function
switches a set of serial coils sequentially by trigger a certain input pulse coil. It has 4 param
eters for proper
configuration. The table below describes each configured parameter, and lists each compatible element for
configuring SHIFT.
In the example below,
①
= 5,
②
= I01,
③
: Q03~Q07.
※
When shift function is enabled, the Q03 will auto-turn ON first, and the rest of the coils still retain the OFF
state. The ON state shifts to Q4 once the input pulse coil was triggered, then Q03 turns OFF. When triggered
signal happened again, the ON state shifts again from Q04 to Q05, and so on. See the above timing diagram for
more information.
