Cooling Coil Leak Detection
Enables the type of leak detection device used to detect
a leak of the motor cooling coil. Set to Optical when
the sensor is the optical type. Set to Float when the sen-
sor is the float type. Set to Disabled when the motor is
not equipped with leak sensors or for service reasons.
The default setting is Disabled. To enable the type of
leak detection:
1. Press MOTOR COOLING COIL LEAK PRO-
TECTION key.
2. A dialog box appears with the selections.
3. Use ◄ and ► keys to select Disabled, Optical or
Float, as appropriate.
4. Press ENTER () key.
Manual Baseline
This setpoint is used to manually enter vibration base-
line values (0.1 to 5.0; Default 2) 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 number, the greater the magni-
tude of vibration represented. A special password is re-
quired. To enter the desired vibration baseline values:
1. Press MANUAL BASELINE key. A dialog box
appears requesting a special password.
2. Using numeric keypad keys, enter 0 3 6 8 and
press the ENTER () key. A green box appears
around the Shaft End vibration baseline value.
3. Press ENTER () key. A dialog box appears giv-
ing the range of values.
4. Using numeric keypad keys, enter the desired
value.
5. Press ENTER () key.
6. Using the ► key, move the green box around the
Opposite Shaft End vibration baseline value.
7. Press ENTER () key. A dialog box appears giv-
ing the range of values.

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
