Operation of IF-105
5.7.1 Normal mode
Functions
Display power saving mode
In normal mode, the display will switch to power saving mode when no buttons have been pressed for ten (10) minutes. In
power saving mode only the decimal points are blinking on the display. Lubrication events are performed according to the
setpoints. The display returns to the 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 pressurisation in hours and minutes. A green LED for
line L1 or L2 shows which line was pressurised last.
The interval is always calculated, except when
" The channel is in alarm mode
" The channel interlocking switch is closed
" The channel is closed (maximum pressurisation time = 0)
Pressurisation
The pressurisation time is shown on the display in seconds. The green LED for line L1 or L2 shows the line being
pressurised. The green LED P indicates that pressurisation is in progress.
The pressurisation can be interrupted by pressing SET.
Pressurisation time display and setting can be changed from seconds to minutes with factory setting parameter Prt. When
the pressurisation time is displayed as minutes, all the decimal points on the display are lit.
Extra lubrication
Extra lubrication can be started if the channel is not currently in alarm mode, turned off or pressurising.
Extra lubrication is started in normal mode by pressing SET when the display shows the time elapsed since the last
pressurisation.
In a dual-line system, both lines are pressurised once. The next line in the set pressurisation sequence is pressurised first.
In a single-line and progressive system, the line is pressurised once.
The extra lubrication can be stopped by pressing SET.
In pressure transmitter operation, the line pressure discharge is measured. A new pressurisation will not start until the
pressure has fallen below the set low limit value.
In pressure switch operation, the system will wait for line pressure discharge. A new pressurisation will not start until after
a set delay.
During the pressure discharge, the display shows the phase code dC.
