erator places the Compressor Switch in the Stop-Reset
(O) position and enters his/her initials, name or user ID
in OPERATOR access level (or higher) using the MO-
TOR LUBE ACKNOWLEDGE key on the MOTOR
LUBRICATION Screen. Refer to the
for entry instructions. The
date and time of this entry is automatically logged as
the Date Of Last Motor Lubrication and Time Of Last
Motor Lubrication. It also resets the Operating Hours
Since Last Lubrication to zero. The date this warning
occurs is stored as the Date Of Last Motor Lubrication
Warning Or Fault. With software version C.OPT.01.16.
xxx (and later), this message will only be displayed if
the Auto Lube Setpoint is disabled. With this setting, if
the Shutdown Setpoint is enabled, this safety shutdown
will occur. If shutdown is disabled, this warning mes-
sage will be displayed but the safety shutdown will not
be performed.
Motor – High Winding Temperature
(Software version C.OPT.01.22.307 and later)
This safety shutdown occurs when either of the follow-
ing conditions are present:
•
Any of the enabled Motor Winding Temperatures
exceeded the programmed High Winding Temper-
ature Shutdown threshold plus the programmed
Winding Hotspot Allowance threshold for 3 con-
tinuous seconds.
-OR-
•
The Average Winding Temperature has exceed-
ed the programmed High Winding Temperature
Shutdown threshold for 3 continuous seconds.
The values programmed for the above safety thresh-
olds are displayed as High Winding Temperature Shut-
down and Winding Hotspot Allowance on the MOTOR
SETPOINTS Screen. They are programmed with the
Winding Setup Setpoint on that screen. The chiller can
be started after all winding temperatures decrease to at
least 18°F (10°C) below the shutdown threshold and
the Compressor Switch is placed in the Stop-Reset po-
sition. This safety shutdown will not occur when the
Winding Temperature Protection Setpoint is set to Dis-
abled on the MOTOR DETAILS Screen. Also, it will
not act on any RTD input registering as an open RTD
or any individual winding temperature sensor that has
been disabled with the Temperature Disable Setpoint
on the MOTOR SETPOINTS Screen.
Motor – High Bearing Temperature
(Software version C.OPT.01.22.307 and later)
This safety shutdown occurs when either of the enabled
motor bearing temperatures exceeds the programmed
High Bearing Temperature Shutdown threshold for 3
continuous seconds. The value programmed for this
safety threshold is displayed as High Bearing Temper-
ature Shutdown on the MOTOR SETPOINTS Screen.
It is programmed with the Bearing Setup Setpoint on
that screen. The chiller can be started after both bearing
temperatures decrease to at least 9°F below the shut-
down threshold and the Compressor Switch is placed
in the Stop-Reset position. This safety shutdown will
not occur when the Bearing Temperature Protection
Setpoint is set to Disabled on the MOTOR DETAILS
Screen. Also, it will not act on any RTD input register-
ing as an open RTD.
Motor – High Bearing Vibration
(Software version C.OPT.01.22.307 and later)
Either the Shaft End or Opposite Shaft End motor
bearing vibration has exceeded the value programmed
for the High Vibration Shutdown Setpoint for the pro-
grammed number of delay seconds. This safety shut-
down does not occur when the Motor Vibration Pro-
tection Setpoint is set to Disabled on the MOTOR
DETAILS Screen or while the WARNING – MOTOR
– BEARING VIBRATION BASELINE NOT SET
warning is displayed. The chiller can be started after
the both vibration values decrease below the shutdown
threshold and the Compressor Switch is placed in the
Stop-Reset (O) position.
Motor – Cooling Coil Leak
(Software version C.OPT.01.22.307 and later)
The Motor Cooling Coil Leak Detector has registered
a fault condition for at least 3 continuous seconds. The
Motor Cooling Coil leak Protection Setpoint enables
the type of sensor employed: If an optical sensor is be-
ing used, the input to the Motor Monitoring Board goes
high to indicate a leak; if a float switch is used, the
input goes low to indicate a leak. This safety shutdown
will not occur when the Motor Cooling Coil Leak Pro-
tection Setpoint is set to Disabled. The chiller can be
started after the leak sensor no longer indicates a leak
and the Compressor Switch is placed in the Stop-Reset
(O) position.
