INSTALLATION AND WIRING :
The HOA-5 and -9 should be mounted indoors, if possible. If the
units must be mounted outside, make certain they are installed
inside a well protected Electrical Enclosure that is free from
moisture and contact with the elements.
If it the HOA-5 is to be used with the IZAC-4 Controller or the
HOA-9 with the IZAC-8 Controller, the best way to install them is
as follows:
1.
First, mount the plastic tracks for both the Controller and HOA
horizontally, so that the tracks line up.
2.
Place the Controller and HOA into the track and
insert one side of the one-piece connector into the
Controller output and slide the HOA's input over
the other side of the connector. The Controller's
output connections will be directly opposite the
HOA's inputs. 18 AWG wire can also be used to
connect the Controller output to the HOA input.
After the positioning the units close together over
the connector, tighten the terminal screws.
WIRING:
(See Figures 1 and 2 for references made to the pin
numbers)
HOA pins 1, 2, 3 are the 24VAC connections to the
Controller. HOA pins 20, 21, 22 connect through to
pins 1, 2, and 3, respectively. The connection from pin
1 to 20 provides a path for the External 24VAC
HOT
,
used by the Controller. The 24VAC supply transformer
is protected between pins 1 and 20 with a fuse and
transorb. Pin 2 connects to pin 21, providing the path
for the 24VAC Return(or neutral). The connection
between pins 3 and 22 is the path for the IZAC
Controller's 24VAC Internal
HOT
(or Input 24VAC
HOT
), taken from another 24VAC source transformer
to drive the 24VAC loads.
Each output of the HOA-5 Module has a dedicated pair
of Output and Output Common terminals for each load
connection. The outputs of the HOA-9 Module have
only one Output Common, shared by all of the
individual load connections. Load connections from the
Controller to the HOA-5, and -9 are made through these
terminals for the respective Controller loads.
Pins 13 to 19 have the same designation for both the
HOA-5 and HOA-9. Pins 13 and 14 provide the
override feedback to the Controller. Pin 14 connects
to one of the controller's 0-10V sensor inputs, pin 13
connects to sensor common. The 0-10V output from
the Controller would connect to pin 15 on the HOA.
The Controller's 0-10V output would then be taken
from pin 16 on the HOA(the 0-10V common would
come directly from the Controller). Provide Pin 17 with
an unreg12- 18VDC, rated for 30mA. Pin 13 is
common for this output. Pin 18 connects to a good
earth-ground, and is critical for proper transient circuit
protection. Pin 19 is the 24VAC internal relay return.
