Limitations of the alternative status page:
•
Set and actual values of power are not displayed and the set value of power is only indirectly accessible
•
Set value of resistance is not displayed and only indirectly accessible
•
No access to the settings overview (MENU button) while the DC input is on
In alternative status page mode, the set values of power and resistance are not adjustable while
the DC input is switched on. They can only be accessed and adjusted in SETTINGS while the
DC input is off.
Rules for manual handling of the HMI in alternative status page mode:
•
The two rotary knobs are assigned to voltage (left knob) and current (right knob) all the time, except for menus
•
Set values input is the same as in standard status page mode, with knobs or by direct input
•
Regulation modes CP and CR are displayed alternatively to CC in the same position
3.4.8 The meter bars
Additionally to the actual values being displayed as numbers, meter bars for U, I and P can be enabled in the
to see where to enable the meter bars in the MENU.
Depiction:
Standard status page with meter bar
Alternative status page with meter bar
The meter bars remain hidden as long as resistance mode, i. e. U/I/R is activated.

Switching the DC input on or off
The DC input of the device can be manually or remotely switched on and off. This can be restricted in manual
operation by the control panel being locked.
Switching the DC input on during manual operation or digital remote control can be disabled by
pin REM-SB of the built-in analog interface. For more information refer to 3.4.3.1 and example
a) in 3.5.4.7.
