Signal output ESS20-001 blue push button in ON position:

(single signalisation N/O) signal contact SC-SI is closed

blue push button in OFF position:

signal contact SC-SI is open

Signal output ESS20-003 blue push button in ON position:

(group signalisation N/C) signal contact SC-SO is closed

(SC-SI is copen)

blue push button in OFF position:

signal contact SC-SO is open

(SC-SI is closed)

Visual indication

LED lighted in ORANGE
