WIRING INSTALLATION GUIDE—NIAGARA AX
Power Wiring
The JENEsys Edge 534 can be powered by wiring to a dedicated Class 2, 24 Vac transformer, or to a 24 Vdc power
source. As shown in Figure 1, the JENEsys Edge 534’s 3-position power connector
(black)
is located at the top corner
of the unit. Unplug the connector from the device and make connections to it as shown.
Note: Do not apply 24 Vac power
(reinsert connector plug into the JENEsys Edge 534)
until all other wiring is
completed, including JENEsys Edge 534 inputs and outputs. Do not power other equipment with it.
Inputs
Each of the 16 universal inputs can support any one of the following:
Type-3 10 k ohm Thermistor
Resistive 0-100 k ohms
0-10 Vdc
4-20 mA
Thermistor
The inputs support 10 k Thermistor temperature sensors using a ThermistorInputPoint.Input accuracy is in the range of
±1% of span. By default, conversion is for a standard Type-3 thermistor sensor, with a sensor range of -10° to
135° F
(-23.3° to 57.2° C).
Using a conversion type of
Tabular Thermistor
, you can specify a different thermistor response
curve, by importing a thermistor curve .xml file.
Pulse
Pulse contacts may have a change-of-state (COS) frequency of up to 500 Hz with a 50% duty cycle.
Note: Minimum dwell time must be > 2ms. For a pulse contact, use the CounterInputPoint in the station database.
Resistive 0-100 k ohms
The inputs can read a resistive signal within a range from 0 to 100,000 ohms. Wiring is the same as shown for a
Thermistor temperature sensor (Figure 2). Resistive signals require a Resistive Input Point.
Note: The universal input option is optimized to provide the best resolution around the 10 k ohm range. For a sensor
with a range far from 10 k ohms
(such as a 100-ohm or 1,000-ohm type),
resolution will be poor. To use such a
sensor, it is recommended you install a transmitter that produces a Vdc or mA signal, and then wire the transmitter
to the UI according to the 0–10 Vdc or 4–20 mA instructions.
