Description

Relay 1: Energized

Relay 2: Energized

The device operates normally, and dust

concentration is below the configured ALERT

and ALARM thresholds.

Voltage is supplied to both relays.

Relay 1: Relaxed

Relay 2: Energized

The dust concentration is above the ALERT

threshold but below the ALARM threshold.

Relay 1 switches status and triggers ALERT.

Voltage is supplied to Relay 2.

Relay 1: Relaxed

Relay 2: Relaxed

The dust concentration is above the configured

ALARM threshold.

Relay 2 switches status and triggers ALARM.

Both relays are relaxed.

The operation logic of the relays is described in Table 17.
