Minimum Off Time: ____ Minutes
Minimum On Time: ____ Minutes
Specifi es the minimum ON and OFF times for switching a load to
its opposite state (i.e., ON to OFF or OFF to ON). That is, once the
satellite contact closes it will remain closed for the minimum ON
time, and once it opens it will remain open for the minimum OFF
time. The range is 0 to 255 minutes
Note that the minimum ON and OFF time has precedence over
demand limiting, overrides, etc.
In local set contact set to:
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:
Make your selection by pressing the once for each
choice until the desired default choice has been selected, and then
press
. The term local set means that communication is
lost between the MCD and the satellite controllers. If HOLD LAST
is selected in the Local Set mode, the contact will stay closed if
it was closed at the time the satellite went into this local set or
will stay open if it was open when the satellite went into local set.
Normal could be used depending on how this Binary Output is
programmed; it may or may not work in a local set condition.
Controlled by input:
Specifi es the point address that acts as the input signal source for
the control range specifi ed.
Keep On Time:
When the binary output is commanded to turn off, this will keep it
on an additional x amount of minutes.
Analog Mode setup:
Analog Mode setup includes normal setpoint, alternative setpoint,
hysteresis, and alternative controlled by fi elds.
Normal Setpoint:
If the “Controlled By” input value rises above this setpoint, the
binary output will be active. Satellite Analog Input 1 to 8.
Alternative Setpoint:
This is an alternate setpoint that is selected when “Alternate
Controlled By” is active.
Binary Output Screen
Hysteresis:
Hysteresis is a software entry that allows an operator to specify
how much a measure variable, such as room temperature, has to
change before the switch changes state. For example, consider
a temperature setpoint of 72 °F with a +/-0.5 °F hysteresis. The
switch will change state (open/close) when the temperature rises
to 72.5 °F and will not switch back to its original state until the
temperature drops to 71.5 °F.
Alternative Controlled By
When this fi eld control point is active, this fi eld controls the
Alternative Setpoint. Values include Week Schedules, Global
Binary, Satellite Control Output, Satellite Binary Outputs.
