Fault Mask

Display Mode

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)
