3.4.6 Switching the main screen view
The main screen, also called status page, with its set values, actual values and device status can be switched
from the standard view mode with three or four values to a simpler mode which only shows two physical values.
The advantage of the alternative view mode is that actual values are displayed with bigger numbers, so they
read be read from a larger distance. Refer to „3.4.3.8. Menu “HMI settings”“ to see where to switch the view mode
in the MENU. Comparison:
Layout 1 (standard) Layout 2 (alternative)
Differences of layout 2:
• The two hidden physical values are shown when switching the knob assignment, which also changes the upper
left half of the display
• The actual regulation mode is displayed no matter what pair of physical values is currently shown, in the lower
leftcorner,astheexampleintheuppergureontherightsidedepictswithCR;thisistheequivalentoflayout1
3.4.7 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 optional analog interface, if installed and if the corresponding parameter is
activated. For more information refer to 3.4.3.2 and example a) in 3.5.4.7. In such a situation,
the device would show a notication in the display.
► How to manually switch the DC input on or off
1. As long as the control panel (HMI) is not fully locked press the button . Otherwise you are asked
to disable the HMI lock, either by simply pressing or entering the PIN, if the PIN has been activated
in menu “HMI Lock”.
2. The ON/OFF button toggles between on and off, as long as a change is not restricted by any alarm or the
device being in “Remote”. The DC input condition is indicated by the two LEDs (green = on, red = off) on
the button.
► How to remotely switch the DC input on or off via the analog interface
1. See section “„3.5.4 Remote control via the analog interface (AI)“ on page 38.
► How to remotely switch the DC input on or off via the digital interface
1. See the external documentation “Programming Guide ModBus RTU & SCPI” if you are using custom
software, or refer to the external documentation of LabView VIs or other documentation provided by EA
