Temperature Controller RES-5008:
The LEDs display additional operating statuses of the regulator besides the functions in the above illustration.
The operating states are shown in detail in the following table:
LED
Blinks slowly (1 Hz)
Blinks quickly (4 Hz)
On permanently
AC (AUTOCAL)
(yellow)
Waiting for mains 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.
