IQ Power HLC Power Supply
& Control Station
5201259 Rev. D
In cases where the user does not want to use the AC adapter but wants to supply
24V
DC power to the IQ Power Remote Display Module, user supplied
24V
DC power may be applied two ways.
The “Power In” connector on end panel of IQ Power Remote Display Module
may be used to supply power to the system. This connector requires the use of a
Switchcraft 760K barrel type power plug. The plug should be wired +24V
DC
to center and common (ground) to outer barrel. The common must be bonded to
electrical ground. Wired in this fashion, the “Power” switch on end panel of Remote
Display Module is in-circuit.
Alternatively, the “Alarm Output” connector on the end panel of IQ Power Remote
Display Module may be used to supply power to the system. This connector
requires the use of a standard DB25 connector. The connector should be wired:
• +24V
DC to pins 13 & 25
• Common (ground) to pins 12 & 24
To ensure current carrying capacity, two pins are used for each connection. The
common must be bonded to ground. Wired in this fashion, the “Power” switch on
end panel of Remote Display Module is bypassed (see Figure 5).
Power supplied in above fashion must have adequate current available to power all
components on system (maximum 1.6A). Input power should be appropriately
fused for safety purposes.
Power Supply Number (Address / Device Number)
Each IQ Power HLC Power Supply has an address (number) associated with it.
These numbers serve to identify the power supply in digital communications. This
address can be a number of 1 through 10 (the default is “1”)
If a Sensor Interface is to be used with an HLC power supply, they will have to
be “paired”. To pair an HLC power supply and Sensor Interface they must have
the same Address number. This will require manually setting the Sensor Interface
Address number to the same as the HLC power supply. They will appear on the
Control Station as a single device with multiple tabs.
For the IQ Power HLC & RDM, the pair will report using the Power Supply
Number (address / device number) of the RDM (Remote Display Module). If a
Sensor Interface is wired with the HLC & RDM, the Sensor data will also report
using the RDM Address number. They will appear on the Control Station as a
single device with multiple tabs.
The power supply address numbers may be manually adjusted or may be
automatically set by the Control Station. Having multiple power supplies with the
same address number connected to a Control Station is not permitted.
