LED Indicators and Optional Display

The GMT220 series transmitter has, as a standard, three LED light

indicators on the cover plate: OPERATION, LEVEL 1 and LEVEL 2 (see

Figure 3).

- The green OPERATION LED is lit when the power is connected.

- The red LEVEL LEDS are lit if the relay setting is reached, for example

when CO

concentration is over the predefined limit. If the relays are

not in use, the LEVEL LEDs indicating CO

concentration are dark.

The transmitter is also available with an optional back lit LCD display,

which outputs the CO

volume concentration in unit of percentage or

ppm depending on the measurement range of the probe.

Blinking led lights and Er-codes in the display indicate operation errors,

see Error Messages on page 25.
