Variable Stage Outputs
(1) Target
- Displays
the target
temperature.
(2) #
- Identifies the
Variable Stage
unit below.
(3) Sensors -
The selected sensor(s) to operate. Active
sensors will be indicated by a number starting
with #1 from right to left. Inactive sensors will
be indicated by a - or hyphen. When "outside-"
is displayed, outside sensor is active. To use
sensors 1,2 and 3, "-----321" should be
displayed.
(4) Mode -
CSTIR, CNEG, CNEGT, CTUN, LIGHT. NOTE: This mode column will indicate how the
stage is Programmed. You are allowed to set any stage at any of these modes. When the stage is
used to control lighting then you must set the mode and curve to Light.
(5) MaxON -
This MaxON column will indicate the current setting for the Maximum onpoint temperature
of the stage. Set this to the temperature you would like for the stage to reach the desired maximum
speed.
(6) MinON -
This MinON column will indicate the current setting for the Minimum onpoint temperature of
the stage. Set this to the temperature you would like for the stage to start running its minimum
speed setting. Minimum speed setting is set at the Minimum Vent screen of the Navigator.
(7) Curve -
This is the motor curve for the variable speed fans. If you are using the stage for lights then
make sure the curve is set for light.
Light
Run lights. Sets light intensity to vary linearly with time.
Fan 1
For use with Cumberland’s line of Funnel Flow fans that are 24” or less. Also, line
voltage must be single phase.
Fan 2
For operation of 36” fans. The power distributed at each percentage is somewhat
greater than that of Curve 1. Therefore, the speed will be a little greater than that of
Curve 1.
Fan 3
For 3-Phase systems. Its purpose is to shift the voltage curve to give a much higher
power from the varied phase. Conditions that would warrant the use of this curve is a
variable speed fan that varies a great deal from 100% speed to 95% speed.
Fan 4
For 3-Phase systems. Its purpose is to shift the voltage curve to give much less
power from the varied phase. Conditions that would warrant the use of this curve is a
variable speed fan that varies very little from 100% speed to 5% speed.
Fan 5
For use with Cumberland’s newest Emerson fan motor, these motors are typically
used on fans that are 24” or smaller.
(8) Time -
None, Min1, Min2, Var, Always ON. This Timer column will indicate what type of timer you
want the stage to operate from. If the stage doesn't need a timer then you must have this setting to
none. Always ON sets the fan to always run at Minimum speed when operating temperature is
below the set Minimum ON temperature.
