SECTION 4
VERSION 6.xx INSTRUCTIONS
OPERATING MODES
Version 6 software provides two operating modes, suitable for internal or remote control of compressor
delivery. While operating, the active mode is displayed in the lower right corner of the message window.
Automatic Mode Operation -
This mode provides automatic start and timed stop. It provides fast
response for small air systems, or power savings in applications with long unloaded periods and
adequate storage to allow the compressor to be stopped for periods of light demands. The display will
indicate this as “AUTO”.
Whenever the plant pressure drops below the programmed “load pressure”, the controller responds by
starting the compressor motor (if it was stopped) and loading the compressor to deliver air at full capacity.
When the pressure rises to the “unload pressure”, the controls unload the compressor, and it no longer
delivers air to the plant system. This cycle repeats, and the controller maintains the pressure within the
programmed band.
If the load and unload cycles are frequent, the controls maintain pressure within the air/oil reservoir to
prevent loss of compressed air. The compressor will reload at the middle of the programmed pressure
band.
A blowdown timer in the controller comes into effect with moderate air storage and longer load and
unload cycles. This timer starts whenever the compressor is initially loaded, and prevents blowdown of
the reservoir. If it has timed out, the reservoir will then be vented during an unload cycle. This reduces
power consumption while the plant continues to operate with its stored compressed air. The timer is
adjustable from 1 to 20 minutes.
A second timer provides additional savings with large storage of plant compressed air. The automatic
time delay is adjustable from 1 to 20 minutes. If the controller operates unloaded for this period with no
demand, the compressor drive motor is halted to eliminate its power consumption. The controls will
remain in this state until pressure drops below the load pressure.
Remote Mode Operation -
This mode may be used to control compressor operation with external
controls.
When used without external loading controls, this provides a convenient means to disable automatic
operation with an external switch, timer, or plant control system. When used with external loading
controls, compressor loading and unloading points are determined by an external contact. The display
will indicate “REM” while in this mode.
PROGRAMMING AND SETUP FOR THE "A" CONTROLLER
Programming and setup is accomplished with the PROGRAM keys.
See Figure 1-1, Keypad. In all
steps, the [ENTER] key enters the displayed value into memory and advances to the next programming
function. The plus [+] and minus [-] keys will increase and decrease displayed numeric values, or step
through menu selections. During numeric adjustments, the left [<] and right [>] arrow keys, move the
cursor (flashing digit) to the position desired. Use the [+] and [-] keys to change the number at the
cursor. At any point in the programming and setup routine, the [STOP/RESET] key can be pressed to
exit the adjustment mode without altering the adjustment. In all steps of the programming routine, the top
line of the display will give a description of the parameter to be programmed, while the bottom line shows
the variable that may be altered or stored.
The following is a step by step guide to programming the "A". Remember, between each step,
it is necessary to press the [ENTER] key to store the new value and advance to the next step.
