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.

pressurization Pis blinking.

IF1051AEN.doc 03.01.2013 Rev. 1A 9 (12)
3.3.1 Low level alarm
The channel triggers a low level alarm, stops pressurization and goes into alarm mode, if the lubricant reservoir 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 Pfor 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.
3.3.2 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
pressurization phase starts or if the line pressure does not rise high enough during pressurization time.
Alarm, high pressure
If the line pressure is not low enough at the beginning of the pressurization phase, code AHP is blinking on the display
and the red LED-signal L1 or L2 of the line that triggered the alarm is blinking.
