Lubrication
Displays the run hours (in whole hours) accumulated
since the last motor lubrication. The greater of Mo-
tor #1 Operating Hours or Motor #2 Operating Hours
is used for this calculation. The value is reset to zero
whenever the Operating Hours (on the Operations
Screen) is reset to zero or whenever the Operator en-
ters his/her initials, name or user ID using the Motor
Lube Acknowledge key.

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 pressing the Motor Lube Acknowledge
button and then 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
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 lubrica-
tion warnings displayed at 1000, 1200 and 1400 (safety
shutdown) operating hours since last lubrication are
unnecessary. Therefore, when the automatic lubrica-
tion hardware is present, this setpoint must be EN-
ABLED. With this setting, no lubrication warnings or
safety shutdown will occur. If DISABLED, as it should
be when not equipped with the automatic lubrication
hardware, the motor lubrication warnings and safety
shutdown will occur at the associated operating hours.
