Additionally, indicator I8 shows that the pump is running.
M: Manual reset with [Alarm Reset] button B1.
A: Automatic reset.
Status mode
The display can be switched to status mode by pressing [Alarm
Reset] button B1 (fig. 4) for 5 seconds.
The first three lines shows the status of inputs and outputs.
The fourth line shows the maximum voltage (OV) applied to the
controller and the earth fault limit (GND). The earth fault detection
is optional (option B13). The display switches back to normal
mode after 10 minutes, or when the [Alarm Reset] button is
pressed.

Display 1 in status mode
The table below gives an overview of inputs and outputs.
Simulation mode
The display mode can be switched to phase-reversal simulation
by pressing [Alarm Reset] button B1 (fig. 4) for more than
10 seconds. See fig. 8.
During this simulation, indicator light "Phase Reversal" (fig. 4,
pos. 2) is on, and alarm relay "Ph. Rev." is activated.

4.4.5 Display D2 (pressure status)
The display shows the pressure status of the system.
Fig. 10
Display 2
The display is divided into two lines. The first line shows day and
time, or status messages. The day and time are always shown.
If a message must be shown, the display will be scrolling
successively at intervals of ± 1 second.
The last digit indicates whether the weekly test is enabled (E) or
disabled (D). If a timer count-down (on timer and off timer) is
activated, the remaining time will be shown to the right instead of
E or D.
If manual stop is required (automatic stop function is not
enabled), the word "MANU" will be shown to the right.
The second line shows the pressure status. The first group of
digits shows the cut-out pressure, the second group shows the
cut-in pressure, and the third group shows the actual system
pressure. The pressure can be displayed in PSI (P) or bar (B).
The display also gives access to the setting menus of the
controller. See section
4.4.6 Indicator lights on control panel
Four indicator lights show the status of the controller and pump.
The indicator lights and their indication are described in the table
below.

Indication
1
Power
Available
This indicator light indicates that the
power is acceptable on all three
phases, and the phase sequence is
correct. The power is acceptable if the
voltage is more than 85 % of rated
voltage.
2
Phase
Reversal
This indicator light indicates phase
reversal of the power source.
3
Pump
Demand
This indicator light indicates an
automatic start condition. It is activated
when the system pressure falls below
the cut-in pressure. It is deactivated
when the run time has expired (if the
function is enabled), or when [STOP]
button A3 (fig. 3, pos. 3) is pressed.
4
Weekly Test
This indicator light indicates that the
system is in operation due to a weekly
test. The weekly test is programmable.
The weekly light is also on during
manual test.
