10. This completes the operational adjustments. The controller will return to the main adjustments menu.
Maintenance Adjustments
1. If any service advisories are in effect (yellow ADVISORY indicator is on), they will be displayed on the top line.
The bottom line indicates
"LEAVE ADVISORY"
(do not reset) or
"CLEAR ADVISORY"
(turn it off). Select the
desired action and press [ENTER] to proceed.
Note that both the
"CHANGE OIL"
and
"CHANGE OIL FILTER"
advisories are based on operating time. These
timers are not automatically reset on the controller when the advisory is turned off, and the advisory will come
back on shortly after the unit starts running. If the oil or filter has been changed, clear the advisory as noted
above, then proceed to the following steps to reset the appropriate timer back to its full value.
2. The top line displays
"NEXT OIL CHANGE"
and the estimated hours remaining are displayed on the bottom line.
The actual time will be affected by operating conditions which affect oil life. Press the [+] or [-] keys to switch to
the oil change interval (see UNIT SETUP) if service was performed early. Press again to change back to
remaining time. When the desired value is shown, press [ENTER] to save and proceed to the next step.
If the advisory message is on, it must be cleared as noted in step 1.
3. The top line displays
"NEXT OIL FILTER"
and the hours remaining are displayed on the bottom line. Press the
[+] or [-] keys to switch to the oil filter interval (see UNIT SETUP) if service was performed early. Press again to
change back to remaining time. When the desired value is shown, press [ENTER] to save and proceed.
If the advisory message is on, it must be cleared as noted in step 1.
4. This completes the maintenance adjustments. The controller will return to the main adjustments menu.
Sequence Adjustments
See "SEQUENCING COMPRESSORS WITH THE AUTO SENTRY
®
-ES+" for more details on setting up and
optimizing a sequenced compressor installation.
1. In the top line,
"NUM OF SEQ UNITS"
is displayed. The bottom line will indicate a number in the range of one
through eight. This will be factory set at "1". This should be set to a number corresponding to the number of
compressors that are currently installed on this air system that also have controllers. It should be noted that all
controllers on the system must have the same number programmed here to operate correctly in SEQUENCE
mode. Adjust as required, and press [ENTER] to proceed.
NOTICE
Setting the value in step 1 to one indicates that no sequencing is to take place. Consequently,
steps 2, 3 and 4, which relate to sequencing, are skipped by the controller. The adjustments
will continue with step 5
2. In the top line,
"UNIT NUMBER"
is displayed. The bottom line will again indicate a number of one through eight
and be factory set at "1". Enter a different number for each controller in a sequenced system. The sequence
mode will not function properly if two or more compressors have the same UNIT NUMBER. Example: 1, 2, and 3
for a three compressor installation.
This is the only setting which must be different for each member of a sequenced system. All other settings
should normally be the same for all members.
3. In the top line,
"TRANSFER INTERVAL"
is displayed. The bottom line will indicate a number of hours in the
range of 1 to 5000. It is factory set at 24. This is the number of hours that this machine will stay in the role of
"lead" compressor.
Normally it is desirable to set this to the same value on all sequenced units to equalize running hours. Different
values may be programmed, if desired, to help equalize hours.
