Note

LED 3 exists only on devices with digital inputs.

With the line 1 or 2 LEDs, the fault mask indicates whether the power supplies are monitored with the signaling contact.

L1 or L2 LED

-Lit green; in other words the corresponding power supply (line 1 or line 2) is monitored. If the power supply falls below 14 V, the signaling contact responds.

-Not lit, in other words the corresponding power supply (line 1 or line 2) in not monitored. If the power supply falls below 14 V this does not trigger the signaling contact.

The fault mask can be set again with the button on the front panel of the OSM/ESM (see 4.2.4.2)

The "Select/Set" button on the front panel of the OSM/ESM changes the display mode of the display mode LEDs. Using this button, a new status can be programmed for the fault mask (see 4.2.4.2)
