SECTION 2 - OPTIVIEW CONTROL CENTER INTRODUCTION
High Vibration Warning
Displays the High Vibration Warning threshold for
the Shaft End and Opposite Shaft End bearings. Not
shown when the Motor Vibration Protection Setpoint
on MOTOR DETAILS Screen is set to Disabled. The
threshold used for this setpoint will either be the val-
ues entered by the Vibration Setup Setpoint or values
derived from the Vibration Baseline Setpoints (refer to
Vibration Setup on Page 116). Also displayed is the
Delay, which is the amount of time the vibration must
exceed the warning threshold before the warning is dis-
played.
Vibration Input Gain
Displays the Vibration Input Gain value, as programmed
with the VIBRATION GAIN Setpoint key. Not shown
when the Motor Vibration Protection Setpoint on MO-
TOR DETAILS Screen is set to Disabled.
High Bearing Temperature Shutdown
Displays the High Bearing Temperature safety shut-
down threshold, as programmed with the BEARING
SETUP Setpoint key. Not shown when Bearing Tem-
perature Protection Setpoint on MOTOR DETAILS
Screen is set to Disabled.
High Bearing Temperature Warning
Displays the High Bearing Temperature warning
threshold, as programmed with the BEARING SETUP
Setpoint key. Not shown when Bearing Temperature
Protection Setpoint on MOTOR DETAILS Screen is
set to Disabled.
For fields requiring access level of SER-
VICE. Service Technicians refer to the
OptiView Control Center - Service Instruc-
tions (Form 160.76-M1) for operation
instructions and explanation of all pro-
grammable setpoints and displayed values.
PROGRAMMABLE
Temperature Disable
Access Level Required: ADMIN
Only shown when access level is ADMIN and Wind-
ing Temperature Protection Setpoint on MOTOR DE-
TAILS Screen is not set to Disabled. Allows a Service
Technician to disable individual winding temperature
116
sensors. The respective temperature data box reflects
enabled or disabled status. This could be applied to de-
fective sensors or for service reasons. When a sensor is
disabled, the respective temperature data box does not
appear on the MOTOR DETAILS Screen.
Winding Setup
Access Level Required: SERVICE
Not shown when Winding Temperature Protection
Setpoint on MOTOR DETAILS Screen is set to Dis-
abled. Allows a Service Technician to program the High
Winding Temperature (266 to 320°F; default 311) and
Winding Hotspot Allowance (0 to 18°F; default 0) safe-
ty shutdown thresholds. Values entered are displayed in
the respective data boxes.
Vibration Setup
Access Level Required: SERVICE
Not shown when Motor Vibration Protection Setpoint on
MOTOR DETAILS Screen is set to Disabled.
Allows a Service Technician to program the High Vi-
bration Shutdown (2.0 to 30; default Baseline X3) and
WARNING (1.0 to 15; default Baseline X2) thresh-
olds for the Shaft End and Opposite Shaft End bear-
ings, along with the desired delays (shutdown - 0 to 30
seconds, default 15; WARNING - 0 to 120 seconds;
default 30). The vibration thresholds are not in any par-
ticular units of measure. They are relative values. The
larger the number, the greater the magnitude of vibra-
tion represented.
The thresholds used for Shutdown and warning will
be either the values entered by this Vibration Setup
Setpoint or values derived from the Vibration Base-
line Setpoints. The values used by the software depend
upon the sequence in which the setpoints are entered.
If Vibration Baseline values are established (on the
MOTOR DETAILS Screen with either the MANUAL
BASELINE key or the AUTO BASELINE key) after
thresholds have been entered with the Vibration Setup
Setpoint, the baseline derived Shutdown and Warning
thresholds override the thresholds entered with the Vi-
bration Setup Setpoint. Thresholds entered with this
Vibration Setup Setpoint, after baseline derived Shut-
down and Warning thresholds are entered, override
Baseline derived values. The active threshold values
are displayed in the Motor Bearings High Vibration
Shutdown and High Vibration Warning data boxes on
this screen.
