The MOTOR LUBRICATION Screen, accessible from
the MOTOR Screen in any access level, displays infor-
mation applicable to this feature.
When both motors have been lubricated, the operator
must acknowledge the lubrication has been performed.
This is done by entering his/her initials, name or User
ID as a 3 to 8 character string. The entry is displayed as
the operator initials at Last Lubrication. The date and
time of this entry is automatically logged as the Date
of Last Motor Lubrication and Time of Last Motor Lu-
brication. This entry also resets the Operating Hours
Since Last Lubrication to zero.
This entry also resets the motor lubrication warning
messages: WARNING – MOTOR BEARING LUBE
SUGGESTED, WARNING – MOTOR BEARING
LUBE REQUIRED and safety shutdown MOTOR –
LACK OF BEARING LUBRICATION.
Enter your initials, name or User ID using the follow-
ing procedure. The entry must be a minimum of 3 char-
acters and a maximum of 8 characters.
1. At the keypad, log in at using Password 9 6 7
5. If resetting the safety shutdown “Motor – Lack

Motor Lube Date
Normally, the Date of Last Lubrication is automatically
recorded when the operator enters his/her initials, name
or User ID with the MOTOR LUBE ACKNOWLEDGE
key in the above procedure. However, if it is necessary
to modify the motor lubrication date after that procedure
was performed, proceed as follows:
1. At the keypad, login at ADMIN access level.
2. Press the Motor Lube Date key.
3. Using the number keys, enter the desired date.
4. Press the ENTER (
) key.
Software version C.OPT.01.16.xxx (and later) adds
the Auto Lube and Shutdown setpoints to the MOTOR
Screen.
The Auto Lube setpoint accommodates those chillers
that are equipped with Automatic Motor Lubrication
hardware that automatically lubricates the motor. Since
chillers that are equipped with Automatic Motor Lu-
brication hardware don’t require manual lubrication,
the motor lubrication warnings (reminders) and safety
shutdown are unnecessary. Therefore, when the auto-
matic lubrication hardware is present, the Auto Lube
setpoint must be ENABLED. With this setting, no lu-
brication warnings or shutdown will occur.
If the Auto Lube setpoint is DISABLED, as it should
be when not equipped with the Automatic Motor Lu-
brication hardware, the motor lubrication warnings and
shutdown will occur at the associated elapsed run times.
With this setting, the Shutdown setpoint can be used
to enable or disable the safety shutdown that occurs at
1400 hours since last lubrication. The safety shutdown
can be enabled or disabled per the customer’s prefer-
ence. If enabled, the safety shutdown will occur at the
normal 1400 hours. If disabled, a warning will be dis-
played but the safety shutdown will not occur.
Use the following procedure:
1. At the keypad, login at SERVICE access level us-
ing access level 1 3 8 0.
2. From the MOTOR Screen, select the MOTOR
LUBE Screen.
3. Press the AUTO LUBE key.
4.
Use the ◄ and ► keys to select Enable or Disable
as desired per above.
5. Press ENTER key.
