9.14.11 Special Conditions
• Cold Reset - When the application has a Cold Reset
request, the OUTPUT will be set to NO_VALUE.
• Warm Reset - When the application restarts from a
power outage or something else, a Warm Reset is
requested. The control loop scans back to find out the
last event before the current time.
• Uninitialized Inputs - If a NO_VALUE appears on DAY
SCHED input, the control's OUTPUT falls back to the
normal day of the week.
If a NO_VALUE appears on any other input, the input
value is forced to a predetermined (hard coded) default
value and the control algorithm continues to operate
normally.
• Failed Inputs - If a failure is detected on the DAY SCHED
input, the control’s OUTPUT falls back to the normal day
of the week.
If a failure is detected on any other input, the input value
is forced to a predetermined (hard coded) default value
and the control algorithm continues to operate normally.
9.14.12 Priority of Services
The application prioritizes its activities such as:
1. ENABLE input - The Enable input determines whether
the schedule will be enabled (ON) or disabled (OFF).
When disabled, all the schedule’s outputs, are set to
NONE. If this input is not defined, the controller assumes
it to be ON.
2. EMERG OVERRIDE - The Emergency Override input
allows the user to override the schedule Output to a fixed
digital value. When ON, the schedule overrides the
Output to the value specified in the Emergency Out field.
3. BYPASS - When the Bypass to ON input is ON, the
schedule ignores its own scheduled events and
bypasses the schedule output ON. When the Bypass to
OFF input is ON, the schedule ignores its own scheduled
events and bypasses the schedule output OFF.If both
Bypass to ON and Bypass to OFF are ON at the same
time, Bypass to ON takes priority over Bypass to OFF.
4. DEMAND SHED - If this input is turned ON it will turn the
output of the Time Schedule to the OFF (unoccupied)
state. This input is used for demand shedding in Power
Monitoring and Demand Control applications, and
typically it is only used when the schedule output is
directly controlling a load (lights, fans, and more).
5. Standard scheduling activities - The user defines a
“Standard Schedule” that specifies the ON/OFF times for
each day of the week, and the ON/OFF times for the
holidays/special days.
9.14.13 Control Alarming
There are no alarms associated with Time Scheduling
Control.
9.14.14 Schedule Category
The Time Schedule application provides a category for the
user to specify how the time schedule application is used.
9.15 Demand Control
The Demand Control application monitors power demand on
a metered system (for example, main panel, sub panel, or
unitary equipment and shed configured loads) in response to
high demand situations in the controller.
9.15.1 KWH Calculation
The controller has the ability to calculate energy
consumption based on:
• Analog KW Input (Analog KW signal) - When an analog
KW input is selected, the application calculates the
energy consumption on an hourly, daily, and monthly
basis by integrating the instantaneous power samples
(approximation by finite steps). The application can take
into account a varying sampling frequency of the input
signal to produce an energy calculation.
• Digital Energy Pulse Input (Digital KWh pulse input) -
When a digital energy pulse input is selected, the
application calculates energy consumption on an hourly,
daily, and monthly basis by accumulating the energy
pulses detected on the digital input. The digital input is
able to support energy pulse rates up to 50 pulses per
second. Also, an instantaneous power (KW) output is
calculated. This calculation uses the energy consumed
over a one minute period to calculate the average power
over the minute period.
NOTE
NOTE: There is a single licensed Demand Control
application in the controller. Additional Demand
Control applications can be added with a
separate license key.
