Reading and Setting values
Display/buttons Function
Description
All values are stored in accordance with a channel list, as with TV channels, where each TV channel
corresponds to a particular programme. Here, each channel corresponds to a certain control
parameter or a measured value. The display may either show a value of 1-3 digits, or a channel
number of two digits - a C (Channel) will then be shown on the extreme left. This means Channel
number.
Values may be both read and written; the value flashes when a setting is being changed.
If E (error) is displayed, followed by a number, this is an Error message. See error messages.
The ↵↵ key toggles between the value and the channel number. The value is saved in Write mode.
In channel mode, the + channel number key scrolls forward in the channel list. In Write, the value
increases.
In channel mode, the – channel number key scrolls backwards in the channel list. In Write, the value
decreases.
Save mode
If display keys are not pressed for 1.5 minutes, save mode is tripped and displays decrease in
brightness. As soon as a key is pressed, normal mode is resumed.
