If no valve type is selected, the LEDs signal the status shown on the left. The yellow
LEDs rotate clockwise in pairs.
The “ready” LED blinks
red/green, if the valve number saved last and the
current rotary switch position do not match!
The amplifier is active and utilizes the parameters of the valve type saved last.
Remedy:
If you wish to change the valve, remove the command value and the enable, press
key [Set] > 1 sec and accept the new valve type.
If the rotary switch position was changed accidentally, reset it to the original
valve number.
→ The “ready” LED
is lit green.
In both cases, check the actually connected valve!
Whenever a valve is changed, all changeable parameters are reset to factory
settings!
