2.1 LED-signals for channels
Note! LED-signals CH1 and CH2 for lubrication channels are in use only in systems with two channels.
LED-signal Description
CH1 Red LED-signal is lit, when channel 1 is in alarm mode.
Green LED-signal is lit, when channel 1 is in normal mode.
LED-signal is blinking when channel 1 is selected on the display.
CH2 Red LED-signal is lit, when channel 2 is in alarm mode.
Green LED-signal is lit, when channel 2 is in normal mode.
LED-signal is blinking when channel 2 is selected on the display.
2.2 LED-signals for operation

2.3 Buttons
Note! The buttons affect only the channel which is selected on the display.
Button Description
In normal mode, the button is used to browse set values on the display.
In setting mode, the button is used to change the value on the display.
In normal mode in a MonoFlex- and a DuoFlex-system the button is used to browse the
pressure displays of the lines.
In normal mode in a ProFlex system the button is used to go to the pulse counter display.
In setting mode, the button is used to move to the next character of the display.
When browsing the set values, the button is used to return to normal mode.
SET In normal mode, the button is used to start extra lubrication, to stop pressurization or reset an
alarm.
In setting mode, the button is used to save the changed value.
When browsing the set values, the button is used to go to the setting mode.
When a button is pressed, all green LED-signals are lit for a moment. This indicates that the information about a
button being pressed has been transmitted forward.
2.4 Display
Note! The display indicates the operation of the channel which is selected on the display.
User interface has a display of 3 characters and 3 decimal points.
The display shows the time and, in pressure transmitter operation, also pressure.
Time and pulse display
The set value for the lubrication cycle and the elapsed interval are displayed as hours and minutes. Decimal point is
used to separate hours and minutes.
Time displayed Display format Example
0 min - 59 min H.MM 12 min = 0.12
1 h - 9 h 59 min H.MM 1 h 20 min = 1.20
10 h - 99 h 50 min HH.M 12 h 50 min = 12.5
100 h - 999 h HHH. 120 h = 120.
The set value for the maximum pressurization time and elapsed pressurization time are displayed as seconds without
the decimal point.
The set pulse amount and the counted pulses are displayed as integers, without a decimal point.

3 Operation
3.1 Normal mode
3.1.1 Functions
Display power saving mode
In normal mode, the display shifts to power saving mode when no buttons have been used for ten (10) minutes. In
power saving mode only the decimal points are blinking on the display. Lubrication events are performed according to
the set values. The display returns to normal mode if any button is pressed or if there is an alarm.
Interval counting
In normal mode the display shows the time elapsed since the last pressurization as hours and minutes. Green LED-
signal for line L1 or L2 shows which line has been pressurized last.
Interval time is counted always, except when
•channel is in alarm mode
•interlocking switch of the channel is closed
•channel is closed (maximum pressurization time = 0)
Pressurization
Pressurization time is displayed as seconds. Green LED-signal for line L1 or L2 shows the line to be pressurized. Green
LED-signal Pindicates that pressurization is in progress.
Pressurization can be stopped with the SET button.
Pressurization time display and setting can be changed from seconds to minutes with factory setting parameter Prt.
When the pressurization time is displayed as minutes all the decimal points are lit on the display.
Extra lubrication
Extra lubrication can be started if the channel is not currently in alarm mode, closed or pressurizing.
Extra lubrication is started in normal mode with the SET button, when the display shows the time elapsed since the
last pressurization.
In a DuoFlex lubrication system both lines are pressurized once. The next line in the set pressurization sequence is
pressurized first. In a MonoFlex and a ProFlex lubrication system the line is pressurized once.
Extra lubrication can be stopped with the SET button.
In pressure transmitter operation, the line pressure discharge is measured. New pressurization starts only after
pressure in the lines is below the set low limit value.
In pressure switch operation, the system waits for line pressure discharge. New pressurization starts only after the set
delay time.
During pressure discharge phase code dC is displayed.

IF1051AEN.doc 03.01.2013 Rev. 1A 5 (12)

3.1.5 Pressure and pulse displays for lines
Pressure transmitter operation
In pressure transmitter operation, line pressure displays can be selected with the -button. Pressing the button 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 -button.
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.
3.2 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.
3.3 Alarms
System with one (1) channel:
•The system is in alarm mode when the red LED-signal for line L1, line L2 or pressurization Pis 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 Pis blinking.
