Yamaha PW5000 User Manual

■

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.

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.

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).

This indicator will light if the unit’s cooling fan stops 
operating.

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.

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.

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.
