Auto Baseline
This key is used to run the auto baseline routine to au-
tomatically establish a vibration baseline for the shaft
end and opposite shaft end bearings. The vibration lev-
el of each bearing is independently averaged for 1 hour
at 1 minute intervals, while the chiller is running (for at
least 2 minutes. While the routine is running, the time
remaining in the 1 hour routine is displayed on this
screen as "Auto Baseline Time Left XX Min". At the
completion of the routine, the derived values appear
on the Screen as the VIBRATION BASELINE values
(0.1 to 5.0) for the shaft end and opposite shaft end
bearings. These values are not in any particular units of
measure. They are relative values. The larger the num-
ber, the greater the magnitude of vibration. A special
password is required. This key only appears while the
chiller is running and after 2 minutes of compressor
operation. To initiate the Auto Baseline routine:
1. The chiller must be running (for at least 2 minutes).
2. Press the AUTO BASELINE key. A dialog box
appears requesting a special password.
3. Using numeric keypad keys, enter 0 3 6 8 and
press the ENTER (
) key.
4. The Auto Baseline routine begins running.
5. At the completion of 1 hour, the routine termi-
nates and the derived values appear as the Vibra-
tion Baselines for the Shaft End and Opposite
Shaft End bearings.
6. If you need to terminate the routine before the
1 hour completion, repeat steps 2 and 3.
MOTOR SETPOINTS SCREEN
This screen allows programming of the WINDING and
BEARING HIGH TEMPERATURE warning/safety
shutdown thresholds and the high vibration warning/
safety shutdown thresholds, along with the vibration
input gain. Also, individual winding temperature sen-
sors can be disabled on this screen.
Temperature Disable
This setpoint allows the individual winding tempera-
ture sensors to be enabled or disabled. A sensor can
be disabled if it is defective or for service reasons.
Otherwise, it should be enabled. The respective tem-
perature data box on this screen reflects enabled or dis-
abled status. When a sensor is disabled, the respective
temperature data box does not appear on the MOTOR
DETAILS Screen. This key is only shown when logged
at ADMIN access level and Winding Temperature Pro-
tection setpoint on the MOTOR DETAILS Screen is
not set to disabled. Enable or Disable the individual
winding temperature sensors as follows:
1. Login at ADMIN access level.
2. Press TEMPERATURE DISABLE key. A green
box appears around the Motor Windings Phase A
Temperature.
3. Use
◄ and ►
keys to place the green box around
the sensor to be enabled or disabled.
4. When the desired sensor is selected, press the EN-
TER (
) key. A dialog box appears allowing se-
lection of enable or disable.
5. Use left/right arrow keys, select enable or disable,
as desired.
6. Press ENTER (
) key.
7. Repeat steps 3 through 6 until all sensors have
been enabled or disabled as desired.
8. Press CANCEL (X) key to exit.
Winding Setup
This setpoint is used to enter the High Winding Tem-
perature (266 to 320°F; default 311) and High Hotspot
Allowance (0 to 18°F; default 0) safety shutdown
thresholds. This key is not shown when the Winding
Temperature Protection setpoint on the MOTOR DE-
TAILS Screen is set to disabled. To enter desired values:
1. Press WINDING SETUP key. A green box ap-
pears around the High Winding Temperature
Shutdown setpoint.
2. Press ENTER (
) key. A dialog box appears with
the range of allowed values.
3. Using numeric keypad keys, enter the desired
value.
4. Press ENTER (
) key.
5. Use Up/Down arrow keys to place the green box
around the Winding Hotspot Allowance setpoint.
6. Press ENTER (
) key. A dialog box appears with
the range of allowed values.
