Building Control
- Totalizing software automaticallymonitors any
operator-defined flow such as airflow or calculated
values such as BTU consumption, and generates a standard monthly report.
- Boolean processing software enables the operator to devise customized
control functions using true/false logic statements.
Tracer L, 100, and 100i offer the following capabilities to control system
functions and provide equipment control strategies:
- Time of day scheduling allows the operator to define equipment schedules
for each weekday, plus holiday and exception schedules.
Time of day scheduling provides both time of day start/stop and optimal
start/stop control.
- Demand limiting monitors the building’s electrical demand and
turns off certain electrical loads or resets equipment
setpoints when demand exceeds a specified limit. This helps to reduce peak
power demand and subsequent utility costs. Each demand limited load has a
maximum off time and temperature limits to ensure
occupant comfort.
- Chiller sequencing sequences and automatically rotates up to six
chillers and their associated pumps to control and
monitor chiller operation. The sequencing program can be used to control virtually
any type of water chiller.
- Priority control allows the operator to define custom control sequences
that respond to alarm conditions. Priority control
sequences receive the highest priority, overriding all other control
sequences.
- Process control language (PCL) allows the operator to create custom
control sequences which complement standard control programs by addressing a
building’s individual requirements. PCL routines
perform calculations based on real time data, and can use analog and binary
point values, alarm status, constants, equation variables, and mathematical and
logical operations.
- Timed override allows the operator to temporarily turn on a device or a
specified equipment group that was scheduled off. Timed override can
be activated by a switch on a zone sensor or by a
keyboard command from a CRT. Weekly and monthly timed override reports
document after-hours operation.
ICS Status Displays
All Trane ICS equipment has standard, preformatted displays that provide
current, historical, and diagnostic data.
Tracer L and 100i Hardware
Tracer L and 100i contain a single circuit card that incorporates
processor, memory, and communications functions. Each unit includes battery
backup, RS-232 communications ports, and an optional internal modem. ICS
system hardware includes the Tracer panel, optional
system CRT, and optional printer. Multiple Tracers can be integrated into a single
system through a unit-to-unit communication link.
Tracers can be operated through the standard CRT, or optionally, through
PC-based Tracer Building Management Network or Tracer-Access operator workstations.
These options provide a dynamic operator interface through the use of color graphics. Refer to the Operator Interface
section of this catalog for more information about Tracer-Access and Building
Management Network.
Tracer 100 Hardware
The Tracer 100 is a multiple circuit card unit that uses a card cage
configuration. The component includes battery backup,
RS-232 communication ports, and an optional internal modem.
Tracer 100 has six input/output card slots. A combination of input/output
cards can be used with the Tracer 100.
ICS hardware includes the Tracer 100 panel, optional system CRT, and optional
printer. Multiple Tracer panels can be integrated
into a single system through a unit-to-unit communication link.
The Tracer 100 can be operated through the PC-based Tracer Building
Management Network or Tracer-Access operator workstations. These options provide
a dynamic operator interface through the use of color
graphics.
