Redbusbar CircuitSpy 80, Installation And Operation Manual

5 Operation
Following configuration, CircuitSpy can be viewed using the WiFi Connection procedure detailed
above. However, when scanning for available access points the modified Panel Name set during the
Configuration step will
now be displayed instead of “CircuitSpy”
CircuitSpy WiFi range is not less than 10m when installed within a metal enclosure, while a 50m
range has been observed on occasion.
5.1 Operation Page
Figure 2 depicts the CircuitSpy Operation page. The Panel Name and the Module Name is displayed
at the top two lines of the page. The section immediately below the module name is the voltage
measurement table that displays the real time voltage present at the eight analogue input terminals.
Below the voltage indicator table is the core temperature of CircuitSpy processor. This temperature
may be used as an estimate of the temperature of the environment within the electrical enclosure.
Normally, the processor core temperature is about 5-10degC above the
panel’s internal ambient air
temperature.
5.2 Voltage Measurement Table
The voltage measurement table displays the terminal name in the left-hand column and its
corresponding voltage in the right-hand column. The cells in the voltage column are dynamically
colour-coded and indicate to the user the state of the circuit: energised, de-energised or outside of the
normal on/off voltage range. For all states, the table indicates the actual voltage at the terminals.
Given a user configured nominal voltage, the table will behave as follows:

Voltage is less than or equal to 20% of the nominal voltage, the voltage cell will be green.

Voltage is between 21% and 79% of the nominal voltage, the voltage cell will be yellow.

Voltage is between 80% and 120% of the nominal voltage, the voltage cell will be red.

Voltage is greater than or equal to 121% of the nominal voltage, the voltage cell will be yellow.
For a given applied voltage, changing the nominal voltage (Vnominal) will only influence the colour of
the background of the voltage measurement cells. It will not influence the voltage displayed ie
changing the nominal voltage will not affect scaling, sampling or any other aspect of voltage
measurement. This ensures an accurate measurement of the applied voltage regardless of the
nominal voltage configuration.
It is important that the correct voltage mode, AC or DC, is selected to ensure accurate voltage
readings. For example, if the applied voltage is 12VDC, CircuitSpy will not display 12V when the
CircuitSpy is in AC voltage mode, and vice versa. This characteristic is a function of the analogue
input circuitry used to offer a wide input voltage range.
6 Maintenance
6.1 Calibration
A calibration check of each CircuitSpy voltage measurement terminal is recommended every 2 years.
A means does not exist to modify voltage calibration. An out of calibration condition requires that
CircuitSpy be removed from service and returned to Redbusbar for repair.
6.2 Cleaning
To clean CircuitSpy, wipe down with a soft cloth that is lightly dampened with water. Do not submerse
in water or use chemical or abrasive cleaners.
