BMS INTERFACE (OPTIONAL)
The
E²
series controller may incorporate a 10 Mbps
communication interface port that can be fi eld connected
through a serial interface to a Building Management System via
Modbus, BACnet, SNMP, or HTTP as confi gured by the factory.
A controller interfaced to a network must be confi gured for BMS
communication.
ALARMS, DRY CONTACT
Alarm conditions shall activate a red LED indicator that backlights
the alarm function key. As an option, an alarm condition may also be
enunciated by an audible alarm signal. An alarm is acknowledged
by pressing the alarm key. This calls up alarm display screens that
provide a text message detailing the alarm conditions. After an
alarm condition is corrected, the alarm can be cleared by pressing
the alarm key.
USER INTERFACE DISPLAY PANEL
The user interface display panel features an easy to read, backlit
liquid-crystal alphanumeric display equipped with contrast
adjustment and LED illuminated function keys. The screens
that appear on the user interface display panel present data
that originates from the controller I/O module. The controller is
operated via a 6-key menu-driven loop structure and offers an
alarm log plus four different interface menu levels to the operator:
Information, Control, Service, and Factory. These menus permit the
user to easily view, control, and confi gure operating parameters
for the CyberRow unit.
OPTIONAL ACCESSORIES
SMOKE DETECTION
A photo-electric smoke detector shall be factory installed and
wired in the evaporator section of the suction side of the evaporator
blower. The air conditioner will shut down upon sensing smoke in
the return air stream.
FIRESTAT
The air conditioner shall be provided with a factory wired and
mounted fi restat. The fi restat will shut down the air conditioner
upon sensing a high return air temperature.
REMOTE WATER DETECTOR: SPOT TYPE
A remote single point water and leak detector shall be factory
supplied and shall ship separately for fi eld installation. Upon
sensing a water leak, the normally closed water detector control
provide users the ability to scroll through and enter various
menu screens.
PASSWORD PROTECTION
Access to the Info Menu, Alarms Log, and the ability to
monitor room conditions shall be allowed without the use of a
password. Modifi cations to the control setpoints shall require
the use of a password. The controller shall be programmed
to recognize predetermined security levels before allowing
access to display screens containing critical variables. Three
secured menu levels (Control, Service and Factory) will
support unique passwords that must be entered to access
the menu screens so only authorized personnel may perform
modifi cations to the settings.
RESTORABLE PARAMETERS/FACTORY
DEFAULTS
Upon initial start-up the CyberRow system shall operate using
the setpoints programmed by the factory. The customer may
enter new operating parameters in the Control menu and
the system will then operate accordingly. The new setpoints
may be stored as, "Customer Default Setpoints". The primary
setpoints entered by the factory still remain stored in the
controller's memory as, "Factory Setpoints". The setpoints
for the system may be readjusted in the Control menu at any
time. If it becomes necessary, the customer may restore the
setpoints back to the Customer Default setpoint values or to
the original factory (primary) setpoint values.
A/C GROUPING pLAN OPERATION
(OPTIONAL)
Multiple CyberRow system controllers shall be able to
connect (grouped) to a pLAN local network, allowing the
communication of data and information from each controller
to a central control terminal or lead controller. The lead
controller display screens can be used to monitor and adjust
group control variables for the individual system controllers.
Each
E²
controller connected to the pLAN network shall be
identifi ed with its own unique address.
Multiple CyberRow units consisting of up to eight STULZ
precision air conditioners equipped with like controllers may
be controlled and monitored via the
E²
series controller.
With multiple CyberRow units each unit can selectively be
confi gured as “Active” to operate as a primary A/C, “Capacity
Assist” for staged operation, or as “Standby” to come online
in case of a failed air conditioning unit to ensure continuous
availability. The controller may also be confi gured to rotate
units with timed duty cycling to promote equal run-time and
ensure that each CyberRow unit within the rotating group is
operationally exercised on a periodic timed basis.
