Operation

Preparation

- Apply power to the amplifier with connected sensors. Wait 15 minutes to warm up.
- Ensure that the completely mounted sensors are loaded with the normal pre-load acting in the regular

operating mode without any additional extraneous loads. In the case of Web tension sensors this is the

roll weight without any web (foil, paper, ...)

Adjustment mode

First press and hold the SET key to switch from the operating mode into the adjustment mode, afterwards

press the menu key

Ü

briefly and release the SET key.

The display indicates the 1. menu step which can now be changed.
For the second, third and any additional menu step do not press the SET key instead use the

menu key

Ü

to select the desired menu point, for instance, to make changes.

Storing of changes

Press the SET key until the LED goes OFF. This activates the adjustment procedure and the LED lights
up until the procedure is completed. The amplifier switches now automatically into the operating mode.

Leaving the adjustment mode without storage

When exceeding the waiting time of 20 seconds the amplifier switches without changes automatically into

the operating mode. An alternative is pressing the menu key beyond the 8. menu step.

Display intensity

(7. Menu step)

select the menu step "display intensity"

in the adjustment mode.

- select the display intensity of the LEDs

- all four LEDs blink during the adjustment

- store adjustment

Filter type of the current output

(1. Menu step)

select the menu point "filter type"

in the adjustment mode

- select the operating mode

- LED blinks during the adjustment

- store adjustment

- if "FIL" was selected then the LED

remains ON in the operating mode
