Delta Controls
Application & Progamming Notes
OBJECTS
The GE Lighting Controller is a programmable device similar to other Application Controllers. Some
objects are automatically created on initial startup (i.e., default database). All other objects are user-
created or deleted as necessary. However, it is important to highlight how certain objects are uniquely
used within the lighting controller in association with the I/O and other product features. These objects are
also all readily accessible over a BACnet MS/TP network.
Object Description
Notes
BI1-12
Binary Inputs
(Field Devices)
User created as necessary to match physically connected
devices, the BI objects represent each of the 12 binary inputs
used for various purposes (including Motion Detectors, etc.)
BI13 Current
Sweeper
Status
User created to represent active Sweeper status. This is only
ON when the Sweeper is active and is turned OFF automatically
when the Sweeper sequence is complete.
BI14
Sweeper Command
Status
User created to represent the last Sweeper command. This is
ON when the last command was to sweep the outputs on, and is
OFF when the last command was to sweep the outputs off.
BO1-12 Binary Relay Outputs &
Status (inc. Low Voltage
Light Switches)
User created to match physically connected relays, these outputs
are used to represent two things:
•
Relay Output (i.e., command)
•
Relay Status (including when controlled by associated
hardwired lighting switches)
E.g. To look for the Status Feedback Value, the property you
should use is:
BV1 = BO1.FBackValue
BO13 Sweeper
Command
User created to provide a means for commanding the Sweeper
in software (via OWS or GCL programming).
Refer to Chapter of the
V3.22 ORCAview Technical Reference Manual
for further information on objects,
and the associated firmware
Release Notes
for which objects are supported.
LOW VOLTAGE LIGHTING SWITCHES
The low voltage lighting switches are physically hardwired to the relays and do not have their own BI
objects, but affect the relay status in their associated BO objects.
•
There is a separate property in the BO which indicates actual relay status or feedback (FbackValue =
Active or Inactive) regardless of what has affected relay operation (software command or manual
switches).
•
Also, whenever the manual switches are used to turn the relay O
N
, the associated BO indicates an
Overridden
condition c/w associated icon (when HandsOffAuto = 1), which can be used in GCL
programming (for occupancy override).
LIGHTING CONTROLLERS WITH NO FEEDBACK (RR7 RELAYS)
General Electric RR7 relays do not have feedback capability. The Delta Controls GE Lighting
Controller, however, defaults to function with feedback. The board will function as though the relays
have feedback, until it is programmed to run in a non-feedback condition.
