10.1.5 Pressure and pulse displays for lines
Pressure transmitter operation
In pressure transmitter operation, line pressure displays can be selected with the -button. Pressing the but-
ton will show the pressure display for line 1 first. Code P1 and the pressure display for line 1 are displayed in
turns. Pressing the button again will show the pressure display for line 2. Code P2 and the pressure display
for line 2 are displayed in turns. If line 2 does not exist, the program returns to display the phase code. From
the pressure display for line 2, the program returns to display the phase code by pressing the -button. The
display returns the phase code automatically to the display after 4 minutes if no buttons have been used.
If a signal from the pressure transmitter is not detected, code _ _ _ is displayed.
Pressure switch operation
In pressure switch operation, the status of the pressure switches of the lines can be selected with the -but-
ton. Pressing the button will display the status of the pressure switch for line 1 first. Code P1 and the status of
the pressure switch for line 1 are displayed in turns. Pressing the button again will display the status of the
pressure switch for line 2. Code P2 and the status of the pressure switch for line 2 are displayed in turns. The
display returns the phase code automatically to the display after 4 minutes if no buttons have been used.
The status closed contact of the pressure switch is displayed with code on and the status open contact with
code oF.
Pulse counter display in the ProFlex system
Counted sensor pulses can be selected on the display with the -button. Code P1 and the pulse counter of
the selected channel are displayed in turns. -button is used to return to the time display.
10.2 Power failure
The set values and program status are preserved in the memory also during power failures. Once the power is
back on, the operation will resume from the status it was in before power failure occurred. Pressurization that
may have been interrupted restarts for the same line. The interval time is not counted during power failures.
10.3 Alarms
System with one (1) channel:
• The system is in alarm mode when the red LED-signal for line L1, line L2 or pressurization P is blinking.
System with two (2) channels:
• The system is in alarm mode when the red LED-signal for channel CH1 or CH2 is lit.
• When the channel selected on the display is in alarm mode, the red LED-signal for line L1, line L2 or
pressurization P is blinking.
10.3.1 Low level alarm
The channel triggers a low level alarm, stops pressurization and goes into alarm mode, if the lubricant reser-
voir is empty. This means that the reservoir’s low level switch is closed. Code AGr is blinking on the display
and the red LED-signal P for pressurization is blinking. Pressurization will restart for the same line when the
low level switch opens and the alarm has been reset by pressing the SET-button.
10.3.2 Pressure alarm, MonoFlex and DuoFlex lubrication systems
The channel triggers a pressure alarm and goes into alarm mode, if the line pressure is not low enough when
