9.1
Display elements and operating elements
The LEDs display additional operating statuses of the controller besides the functions in the above illustration.
These operating states are shown in detail in the following table:
LED
blinks slowly (1 Hz)
blinks quickly (4 Hz)
on permanently
AC (AUTOCAL)
(yellow)
RS bit set (reset) or wait for
line voltage
AUTOCAL requested, but
function is blocked
AUTOCAL is carried out
LED blinks with a different frequency:
Incorrect (too low) supply voltage
OUTPUT
(green)
In control operation, the light intensity is proportional to the heating current.
HEAT
(yellow)

START requested,
but function is blocked
START is carried out
ALARM
(red)
Configuration error,
AUTOCAL not possible
Controller incorrectly cali-
brated, carry out
