Error Indication in Transmitters without
Display
Error codes are cabled by blinking a message with short flashes of the
LED lights.
LEDs are situated on the cover of the transmitter. The green OPERATION
LED is blinking when a non-critical error occurs (no effect on relays). The
red LEVEL 1 and LEVEL 2 LED s are blinking when a fatal error occurs
(switches the relays OFF).
NOTE The red level LED is continuously lit when the predefined CO
2
concentration is exceeded.
