since the last motor lubrication. The greater of Mo-
tor #1 Operating Hours or Motor #2 Operating Hours

Motor Lube Acknowledge
Access Level Required: OPERATOR
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 and implies
that both motors have been lubricated. 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 Suggest-
ed”, “Warning – Motor Bearing Lube Required” and
safety shutdown “Motor – Lack of Bearing Lubrica-
tion”.
Enter your initials, name or user ID using the follow-
ing procedure. The entry must be a minimum of 3
characters and a maximum of 8 characters.

Motor Lube Date
Access level required: ADMIN
Allows modification of the Date of Last Motor Lubri-
cation.
Auto Lube
(Software version C.OPT.11.03.01.004 and later)
Access Level Required: SERVICE
This setpoint accommodates those chillers that are
equipped with the optional Automatic Motor Lubrica-
tion hardware that automatically lubricates the motor
at regular intervals. Since chillers equipped with this
hardware don’t require manual lubrication, the lubri-
cation warnings displayed at 1000, 1200 and 1400
(safety shutdown) operating hours since last lubrica-
tion are unnecessary. Therefore, when the automatic
lubrication hardware is present, this setpoint must be
ENABLED. With this setting, no lubrication warnings
or safety shutdown will occur. If DISABLED, as it
should be when not equipped with the automatic lubri-
cation hardware, the motor lubrication warnings and
safety shutdown will occur at the associated operating
hours. Service technicians refer to procedure in Service
Manual 160.69-M1.
