QUANTUM™ COMPRESSOR CONTROL PANEL S90-010 O
OPERATION Page 9
SENSOR INDICATION BOX:
The following sensors are displayed:
Suction - Suction Pressure and Temp. are
measured at the compressor inlet and the
values are displayed along with the unit of
measure.
Discharge - Discharge Pressure and Temp.
are measured at the compressor outlet and
the values are displayed along with the unit
of measure.
Oil - Oil Pressure and Temp. are measured
prior to entering the compressor and the
values are displayed along with the unit of
measure.
Filter Diff. - If applicable, pressure drop
across the oil filter. The main oil injection oil
filter pressure drop value (differential) is
displayed along with the unit of measure.
Separator - Oil Separator Temp. value is
displayed along with the unit of measure.
Leaving Process - If Process Temperature
Control Modes were enabled in Panel Setup,
the Leaving Process Temperature value is
displayed along with the unit of measure.
Balance Piston - If applicable, the Balance
Piston pressure reading is displayed along
with the unit of measure. This reading is a
measurement of the oil pressure at the
Balance Piston.
SLIDE VALVE and SLIDE STOP (or CAPACITY)
STATUS BOX:
Position - The following values are shown:
• Slide Valve or Capacity is shown
depending on the compressor model
(Reference Compressor Model
Differences)
• Slide Valve - The position is
displayed as a percentage. This
value indicates the mechanical
position of the Slide Valve and does
not indicate the percentage of
compressor capacity.
• Capacity - The position is
displayed as a percentage. This
value indicates the mechanical
position of the Capacity Control
pistons and does not reflect the
percentage of full load operation.
• Slide Stop (If applicable, reference
Compressor Model Differences) -
The position is displayed as a ratio
(volume index (VI)).
Mode - The following are shown:
• Slide Valve or Capacity (Reference
Compressor Model Differences) - One
of the following is shown:
• Auto (Automatic) - Capacity is
being controlled from active
Capacity Control setpoints at the
panel.
• Manual - A manual load or unload
command was sent.
• Remote - The Slide Valve or
capacity is being controlled from a
remote device.
• Slide Stop (If applicable, reference
Compressor Model Differences) - One
of the following is shown:
• Auto (Automatic) - The movement
of the Slide Stop is being controlled
from internal logic at the panel.
• Manual - A Slide Stop manual
increase or decrease command
was sent.
Status - The following are shown:
• Slide Valve or Capacity (Reference
Compressor Model Differences) - One
of the following could be shown:
• Load - Indicates the compressor is
loading and the Slide Valve or
capacity value is increasing.
• Unload - Indicates the compressor
is unloading and the Slide Valve or
capacity value is decreasing.
• Idle - Indicates the Slide Valve or
capacity is holding at the present
position
• Slide Stop (If applicable, reference
Compressor Model Differences) - One
of the following is shown:
• Increase - Moving to a higher VI.
• Decrease - Moving to a lower VI.
• Idle - Not moving.
The following messages could be shown:
At Maximum Load -
Warm Up Load Inhibit 00:00 - The time
period that the Slide Valve will be inhibited
based on the Starting Period Before Slide
Valve Will Load setpoint on the Slide Valve
Setpoints screen.
Slide Valve Pulldown - A message can
appear stating in a percentage the amount
that the Slide Valve has loaded. The
message will appear as Stop Load - Slide
Valve Pulldown: 5% as an example.
Stop Load - If this message is shown, it
indicates that the compressor is being
prevented from further loading. The Stop
Load setpoint that has been reached is
shown next to the stop load message, i.e.
Stop Load - High Motor Amps, this message
indicates that the High Motor Amps Stop
Load setpoint was reached and the
compressor is being prevented from further
loading. One of the following messages
could be shown if the corresponding Stop
Load setpoint is reached:
• High Motor Amps - If the motor amps
is greater than or equal to the High
Motor Amps Stop Load setpoint, the unit
is prevented from further loading until
