FLA - Percent Full-Load Amps displays the percentage of
the drive motor full-load amperage rating that the motor is
currently using.

SV - Slide valve position is displayed as a percentage. This
percentage reflects the mechanical position of the slide valve
and does not reflect the percentage of full-load operation. Im-
mediately below this information, space has been provided to
indicate whether the S.V. % is in the automatic (AUTO), manual
(MAN), or remote (RMT) mode. The microprocessor will con-
trol this function in the automatic mode. To the right of the mode
indicator, these messages may appear:
L (indicates Slide Valve loading)
U (indicates Slide Valve unloading)
C.C. -Actual Capacity Control setpoint or
S.B. - Actual Setback setpoint
SUCT.P - Current Suction Pressure

SLIDE STOP - Slide Stop position is the position selected
by the microprocessor to provide the highest efficiency at
any given suction and discharge pressure condition. Im-
mediately below this, an information space has been pro-
vided to indicate whether V ratio is in the automatic (AUTO)
or the manual (MAN) mode.
RECYCLE - A Recycle Delay message indicates that the com-
pressor has started and has shut down within the time delay
setpoint period. The Recycle Delay will prevent the compres-
sor from starting until the delay time expires and is intended to
prevent damage to the compressor motor from successive re-
starts. During Recycle Delay, the microprocessor will alterna-
tively flash “RECYCLE DELAY” and the remaining delay time
in minutes. The (RECYCLE . . .) message appears only when
the compressor is in the recycle mode.
NOTE: Consult Motor Manufacturer for the recom-
mended duration of the Recycle Delay.
CAUTION: If the [RUN] key is pushed while the unit is in
Recycle Delay, the compressor will start at the end of
the delay period.
ANNUNCIATOR DISPLAY
When a prealarm or cutout occurs, a flashing ALARM or
SHUTD (shutdown) indicator will appear in the upper right
hand corner of the “Operating Display, Page 1” and in the
lower left hand corner of “Operating Display, Page 2”. To
determine the fault, rotate to the Annunciator display by
pressing the [CHANGE] key or press [F5] for direct jump to
annunciator menu.
The Annunciator display will show all failures, individually. If
there is only one failure, the annunciator display will appear
as shown on the following “Annunciator Display”, pages.
When the system has failed for more than one condition,
(USE STEP) will appear in the upper right side of the dis-
