Controls and Connectors

Front Panel

1POWER ON/OFF Switch
After connecting the PW5000 to the PM5000 console
using the cable supplied with the PM5000, and after
plugging the PW5000 power cord into an appropriate AC
outlet, use this switch to turn power to the PM5000 ON
or OFF.
2OPERATION MONITOR
Displays the status of the four independent power supply
lines to the PM5000. The green NORMAL indicators
light when operation is normal. If abnormal operation is
detected on any supply line, the red CAUTION indicator
for that line will light, and the corresponding supply may
shut down. The CAUTION indicator will remain lit even
if the supply is shut down. If this happens, note which
CAUTION indicator was lit, turn the POWER ON/OFF
switch OFF, and contact your Yamaha dealer or
maintenance personnel.
3HIGH Indicator
This indicator lights when the unit’s cooling fan is
operating at its highest speed. High-speed operation can
be activated by either of the following conditions:
• The FAN SPEED switch is set to HIGH.
• The FAN SPEED switch is set to AUTO and the
PW5000’s internal temperature exceeds a preset
threshold (in this case the THERMAL indicator will also
light).
4STOP Indicator
This indicator will light if the unit’s cooling fan stops
operating.
5THERMAL Indicator
Lights if the PW5000 internal temperature exceeds a
preset threshold. If this occurs it is possible that the
unit’s cooling efficiency is being adversely affected by
the setup location or other external conditions. Check
your installation and revise if necessary to allow
unimpeded airflow to and from the unit’s vents.
6LINE VOLTA GE Display
Displays the current AC line voltage. The AC voltage is
continuously displayed as long as the PW5000 is
plugged into an active AC outlet, regardless of the
POWER ON/OFF switch setting.
7FAN SPEED Switch
Sets the speed or operational mode of the cooling fan.
When set to AUTO the speed of the fan will
automatically be adjusted in three stages according to
the unit’s internal temperature. The THERMAL
indicator will light when the highest speed is activated.
When set to HIGH the fan will operate continuously at
the highest speed, regardless of the unit’s internal
temperature.
Never obstruct the cooling vents located on the
front and rear panels of the PW5000.
