Command contact
Can be switched in two ways:
• By closing an external voltage free contact between M and S.
• By connecting 5-35 Vac,dc between M(+) and R(-)
Each diagram represents the effet of the command contact for
the two initial states of the output relay: de-energized (1L) and
energized (1H).
