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 Lubrication. 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

LACK OF BEARING LUBRICATION”.

Motor Lube Date
Access level required : ADMIN
Allows modification of the Date of Last Motor Lubri -
cation.
Auto Lube
(Software version C.OPT.01.16.XXX and later)
Access Level Required : SERVICE
This setpoint accommodates those chillers that are
equipped with the optional Automatic Motor Lubrication
hardware that automatically lubricates the motor at regu-
lar intervals. Since chillers equipped with this hardware
don’t require manual lubrication, the lubrication warn-
ings displayed at 1000, 1200 and 1400 (safety shutdown)
operating hours since last lubrication 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 lubrication hardware, the motor
lubrication warnings and safety shutdown will occur at
the associated operating hours. Service technicians refer
to procedure in Service Manual 160.54-M1.
Shutdown
(Software version C.OPT.01.16.XXX and later)
Access Level Required : SERVICE
If the Auto Lube setpoint above is set to DISABLED,
the SHUTDOWN Setpoint is used to enable or dis-
able the safety shutdown that occurs at 1400 operating
hours since last lubrication. The safety shutdown can
be enabled or disabled per the customer’s preference.
If enabled, the safety shutdown will occur at the normal
1400 hours. If disabled, a warning will be displayed but
the safety shutdown will not occur. Service Technicians
refer to procedure in Service Manual 160.54-M1.
