5.7.5 Pressure and pulse displays for lines
Pressure transmitter operation
In pressure transmitter operation, line pressure displays can be selected with ø. Pressing the button will show the line 1
pressure display first. Code P1 and line 1 pressure display are displayed in turn. Pressing the button again will show the
line 2 pressure display. Code P2 and line 2 pressure display are displayed in turn. If line 2 does not exist, the program will
return to show the phase code. From line 2 pressure display, the program will return to display the phase code when
ø is
pressed. The display will automatically return to display the phase code if no buttons have been pressed in four minutes.
If a signal from the pressure transmitter is not detected, the code _ _ _ is displayed.
Pressure switch operation
In pressure switch operation, the status of the line pressure switches can be displayed with ø. Pressing the button will
display the status of the line 1 pressure switch first. Code P1 and line 1 pressure switch status are displayed in turn.
Pressing the button again will display the status of line 2 pressure switch. Code P2 and the status of line 2 pressure switch
are displayed in turn. The display will automatically return to display the phase code if no buttons have been pressed in
four minutes.
The closed contact status of the pressure switch is shown with the code on and the open contact status with the code oF.
Pulse counter display in a progressive system
The counted sensor pulses can be displayed by pressing ø. Code P1 and the pulse counter of the selected channel are
displayed in turn. You can return to the time display by pressing ø.
5.7.6 Power failure
The setpoints and program status are preserved in the memory also during a power failure. Once the power is back on,
the operation will resume from the status where it was in before the power failure. Any interrupted pressurisation will
restart for the same line. The interval time is not counted during power failures.
5.7.7 Alarms
System with one channel:
" The system is in alarm mode when the red LED for line L1, line L2 or pressurisation P is blinking.
Dual channel system:
" The system is in alarm mode when the red LED for channel CH1 or CH2 is lit.
" When the channel selected on the display is in alarm mode, the red LED for line L1, line L2 or pressurization P
is blinking.
Low level alarm
The channel will trigger a low level alarm, stop pressurisation and go into alarm mode if the lubricant reservoir is empty.
This means that the reservoir’s low level switch is closed. In such a case, the code AGr is blinking on the display and the
red LED P for pressurisation is blinking. Pressurisation will restart for the same line when the low level switch has been
opened and the alarm has been acknowledged by pressing SET.
Pressure alarm, single and dual line lubrication systems
The channel will trigger a pressure alarm and go into alarm mode if the line pressure is not low enough when
pressurisation starts or if the line pressure does not rise high enough during the pressurisation time.
