16. SWITCHING THE COMPRESSOR
After the pressure switch (6) is activated and
circuit breakers FA13 (11) and FA14 (12) are
turned to position I, the compressor air pumps
sequentially come online (the air pumps in the
second column or shelf react with a 2 s delay).
Circuit breaker FA13 (11) functions as the
main switch.
The air pumps switch on (at ≤6 bar) and off (at
≥8 bar) automatically and are controlled by the
LOGO! (13) controller and the pressure switch
(6) based on compressed air usage.
If the motor surface temperature exceeds
40oC,
the temperature switches (10)
automatically turn on the compressor cooling
fans, switching them off once the temperature
decreases to approximately 32
o
C.
16.1. Controller LOGO!
This controller controls the compressors and
dryer valves, monitors and signals alarms (as
described below) and displays the number of
operating hours. It is composed of a base
module and an expansion module. The base
module includes a display and the cursor
(control) buttons ▲, ▼, ►, ◄, OK and ESC.
The expansion module has LED indicators for
RUN and STOP.
The parameters of this unit do not require configuration or set up under
normal circumstances. The LED indicator on the expansion module
should be green once the equipment is connected to its power source
and the display should show the current operating hours.
The displayed hours are only
illustrative.
Proceed in accordance with Chapter 18 if the
indicator is not green.
If the operating hours are not shown, the
compressor may have been disconnected
from the power for an extended period of time
and it must be restarted.
The controller is unable to
archive time and data if it is
disconnected from the power
for more than 80 hours. This
data must be configured when
the equipment is first placed
into
service or after an
extended period in which it has
been placed out of service.
The display shows the main menu.
