ST16135-00E
As a default value the AT - compressor temperature appears in
the bottom of the display.
To select and lock other menu items, scroll to the item required,
when in view press the ENTER button, a flashing key symbol is
displayed.
To cancel the locked selection and flashing key symbol press the
ESCAPE (C) or reset button.
During operation, the controller records the total running hours,
the hours run on load and counts down to the next service
interval.
The service interval is set for 2000 hours when using Fluid Force
Red 2000 oil. This interval will be reduced if the unit operates
above the recommended temperature.
7.1.3
Starting - Automatic Mode
Press the green START button, the compressor will start if system
pressure is below the load pressure (PL) set point. On initial start
with no pressure in the system, the pressure display will quickly
rise to the full delivery pressure. During this period, the green LED
will be continuously illuminated.
The compressor will continue to run and pressure will vary within
the load/unload (PL/PU) pressure set points to match the system
demand.
If system demand reduces and pressure rises to the unload (PU)
pressure set point, the REVS (Reduced Energy Venting System)
sequence (RT) will begin.
If there is an air demand during the REVS run on time sequence
(RT) the compressor returns to full load operation.
If there is no air demand during the REVS run on time sequence
(RT) the compressor will stop.
Automatic restart will occur when system pressure falls to the load
(PL) pressure set point.
7.1.4
Starting - Continuous Mode
Press the green START button, the compressor will start, and run
continuously within the load/unload (PL/PU) pressure set points to
match system demand.
On initial start with no pressure in the system, the pressure
display will quickly rise to the unload (PU) pressure set point.
During this period, the green LED will be continuously illuminated.
7.1.5
Starting - Regulated Speed
For variable speed models, the starting sequence is the same as
that shown for single speed automatic mode except that, instead
of the compressor continuing to run and pressure varying within
the load/unload (PL/PU) pressure set points, the compressor will
continue to run and the speed will vary automatically to match
system demand.
With no system demand when running at minimum speed the
compressor will stop after the REVS venting sequence (RT).
Automatic restart will occur when system pressure falls to the load
pressure (PL) set point.
7.1.6
Stopping – All Models
To stop the compressor, press the red STOP button, system
pressure will remain high initially, but will fall gradually with the
rate of decay depending on system usage.
7.1.7
Emergency Stop
If an emergency occurs, press the EMERGENCY STOP button.
The button will lock in the depressed position and stop the
compressor immediately.
The red LED on the controller will flash quickly together with
display symbols.
Clear any faults that may have occurred. Do not reset until it is
safe to do so.
Reset the emergency stop button by twisting clockwise before
restart.
Press the RESET button on the controller to cancel the red LED
and display symbols.
Operation of the emergency stop button is recorded in the
controller error log.
7.1.8
Compressor Vent Down
Venting is controlled automatically by the REVS system for either
operating mode for all models.
