E2610-LEL
Rev 10.05.2021
Operation
Turn on the power. During the first ca.60 seconds after powering on E2610 performs a
warming-up and self-diagnostic routine, indicated by the flashing of each LED. The upper
dual-color LED remains continuously green in normal operation and blinks red in case of
device or sensor fault.
The warm-up time depends on the sensor type, unpowered period, and atmosphere. During
the first 30 seconds after powering on you may select the automatic or manual mode of
alarm release. By shortly (< 2 s) pressing the button on the device’s front panel you enable
the automatic mode, by pressing the button for 2...10 s — manual mode. The activation of
the automatic mode is followed by a single LED blinking and acoustic signal. If manual
mode is activated, the double acoustic and light signal follows.
If the gas concentration exceeds the LOW alarm setpoint, the bottom red LED starts
flashing at a rate of 1 Hz, and the relay RE1 switches over. The first alarm stops
automatically if the gas concentration drops below 70% of the LOW alarm setpoint.
If the gas level exceeds the HIGH alarm setpoint, the bottom red LED starts flashing and
the buzzer starts beeping at a rate of 2 Hz, and also the relay RE2 switches over.
Depending on the selected release mode, the HIGH alarm stops automatically or can be
stopped by pressing the button, on condition that the gas level has dropped below 70% of
the LOW alarm setpoint.
Beyond the warm-up period, holding down the button for 2...10 seconds and releasing
causes E2610 to reset and perform the self-diagnostic routine for testing purposes. When
holding the button down for over 10 seconds, E2610 imitates the reaching of the HIGH
setpoint with the respective light and sound indication and switching over the relays.
