IMPORTANT: The timer should initially be preset to
90 minutes intervals as this has been found to be the
optimal grease delivery interval for most applications.
However, certain operating conditions will require
more or less than this amount.
It is the responsibility of the operator to ensure that
the machine parts are receiving sufficient lubrication.
Hotter operating conditions cause the grease to
become thinner and may therefore require more
frequent interval settings.
Over lubrication, as well as under lubrication, can
lead to premature failure of machine components
and should be avoided.
Interval Adjustment
The interval time between two successive lubrication
cycles can be adjusted using the step switch. One
of ten time intervals can be selected. The standard
version has time intervals increasing by 0.5 h steps
(0.5, 1.0, 1.5... 5 h). If the power supply is switched
off during a cycle the cycle will be ended. When the
power supply is switched on again a complete new
cycle will be started.
Timer Alarms
Alarm signals can be generated by the electronic
timer in various circumstances.
The standard version uses a built-in buzzer. In other
versions another (external) alarm indicator can be
fitted, for example a lamp.
The alarm signal is generated in the following
situations:
• After reaching 70% of the cycle time (70% of 3
minutes = 2 minutes) the pressure switch should
have connected to earth. If this is not the case
- because insufficient pressure has been built up -
then a continuous alarm signal is generated.
• The electronic timer runs a self-test after the
power supply is switched on; if there is a fault
condition an intermittent alarm is generated. This
can occur if no interval is selected by the step
switch.
If the electronic timer sounds an alarm to indicate
that the timer or greasing system is not functioning
properly, it is strongly advised to examine (or have
examined) the greasing system and if necessary to
make repairs. If this is left too long, damage can be
caused to either the sprayer or the greasing system.
The greasing system is controlled by an electronic
timer. The timer produces, at set time intervals
impulses lasting 3 minutes. These impulses energize
the solenoid valve in the air supply to start the
lubrication cycle. The interval between successive
lubrication cycles is adjusted on the electronic timer.
If during a cycle the power supply is switched off, a
complete new lubrication cycle will restart when the
power supply is again switched on.
