Main Adjustments Menu
1. The compressor must be stopped prior to making any adjustments. If the unit is running, press the
[STOP/RESET] key to place the control in the "READY" state.
Adjustments can also be performed from the "SHUTDOWN" state. After adjustments are completed,
the controller returns to this state until the cause is repaired and the controller is manually reset.
2. Press the [ENTER] key to begin programming. This enters the adjustments menu. The adjustments
are broken into five groups as shown in Figure 4-1. To select a group, press [+] or [-] until the desired
group is shown on the bottom line of the display. Press [ENTER] to proceed to the group
adjustments detailed below.
Operation Adjustments
1. In the top line, "LANGUAGE" is indicated. The bottom line will indicate "ENGLISH" or an alternate
language for display messages. Select the desired display language and press [ENTER] to proceed.
If a controller is set for another language, press the [STOP/RESET] key, press [ENTER] twice, and
press the [+] or [-] key to select ENGLISH at this step. Then press [ENTER] to select the language.
2. In the top line, "DISPLAY UNITS" is indicated. The bottom line will indicate "ENGLISH" (PSIG,
Fahrenheit) or "METRIC" (Bars, Celsius) units of measurement. Select the desired display units and
press [ENTER] to proceed.
3. In the top line, "START TIMER" is displayed. The bottom line will indicate a time between 2 and 10
seconds. This is the time that the controller spends in the unloaded 'start' mode. This also controls
the operation of package-mounted wye-delta starters, if so equipped. Set this adjustment for the
amount of time needed for the motor to reach its highest speed while starting. This is typically 3
seconds for full-voltage starters, 7-9 seconds for wye-delta starters.
If a remote-mounted, reduced voltage starter is used, set this adjustment 1-2 seconds longer than the
starter's internal timer.
4. "UNLOAD PRESSURE" is displayed and adjusted next. The bottom line will indicate a pressure
value. It is to be set at the nameplate rating of the compressor for normal operation. Under NO
circumstances, is this adjustment to be set in excess of the compressor nameplate pressure. It may
be set lower, if desired, to reduce pressure and power consumption.
5. In the top line, "LOAD PRESSURE" is displayed. The bottom line will indicate a pressure value. This
setting determines the point at which machine startup occurs in AUTO mode and when the
compressor will load up from the blown down condition. Note that LOAD PRESSURE can be set up
to 5 PSI below UNLOAD PRESSURE. Set this lower to reduce compressor cycling.
6. In the top line, "BLOWDOWN TIME" is displayed. The bottom line will indicate a time between 1 and
20 minutes. It is factory set at 10 minutes. This is the minimum time interval between blowdowns. A
longer blowdown time minimizes wasteful dumping of compressed air when loading is likely to occur
in a short time.
7.
In the top line, "AUTO TIME" is displayed. The bottom line will indicate a time between 1 and 20
minutes. It too, is factory set at 10 minutes. Its function is to prevent too frequent motor starting, and
to allow the motor a 'cool-down' period before stopping.
