• PWM: Pulse Width Modulation controls the amount of power given to a device by cycling the on/off phases of a
digital signal. PWM consists of a duty cycle and frequency. The Duty Cycle measures the amount of time a signal is
in the ON state as a percentage. The frequency controls how fast the PWM cycle is repeated. Users can select
between the following settings:

Alarms
Figure 38
Figure 39
Alarms are set by clicking the icon on the desired input signal found in the Input Configuration Tab. Setup the
threshold and alarm type in the Condition section and then select which output to turn on in the Action section. The
alarm can be set to be latching or non-latching in the Recovery section. If the alarm is set to be latching, press the reset
button on the XW Transmitter to clear the Alarm.
The alarm state is now viewable on the ZW-REC webpage by monitoring the DIN input.
Note: When alarms are enabled readings are taken once per second. This greatly reduces battery life, therefore an
AC Adaptor is recommended.
ON/OFF Control
To configure ON/OFF Control on a device, navigate to the
Output configuration tab in SYNC and click on the icon
located to the right of the available outputs. Clicking the
icon will open the Define ON/OFF Control dialog box as
seen in Figure 36. Choose the input with the active alarm
that you would like to control and set your preferred
parameters.
The Setpoint establishes the target process value and the
Deadband establishes the range from the Setpoint that the
process value can accept before the output is activated.
When Reverse control is selected, the output is on when the
process value is below the Setpoint. When Direct control is
selected, the output is on when the process value is above
the Setpoint.
Once the ON/OFF Control parameters have been set, click
Save to finalize the settings.
More functions are constantly being developed for the XW Transmitter and other smart devices. Check the latest SYNC
version for the newest updates.

I/O Signal
Description
INP_1, INP_2, INP_3
Inputs may be treated as simple ON/OFF switch inputs.
I/O Signal
Description
Detects the positive or negative pulse edge depending on the signal type and
modifier chosen.
RST
Resets the value to 0 when active.
Enables measurement when active.
Holds the last measurement when inactive.
Serves as the second signal line and is measured alongside CLK_A to determine
the Pulse Delay.
The following information provides descriptions and diagrams of the available I/O capabilities of the XW-ED and XW-EDPRO.
Digital Input
• DIN: The Digital I/O functions present a bit mapped image of the signals present on the corresponding
channel signal lines. The Digital I/O signal lines may be read as inputs to initiate control functions and to
activate alarms.
Pulse Measurements
Pulse measurements include Pulse Rate (Frequency), Pulse Width, Duty Cycle, and Pulse Delay. Pulse
measurements contain the following customizable I/O signals:
CLK_A
ENB
CLK_B (Delay only)
• RATE: The Rate (Pulse Rate Frequency) function measures the number of OFF to ON transitions in 1 second.
Rate counters may be used to measure the frequency of external signals and are often used to measure
speed/flow by coupling a magnetic transducer to a toothed wheel or impeller-based flow transducers.
• WIDTH: The Pulse Width function measures the time (in seconds) that the CLK (clock) signal is in the ON
state. Width timers may be used to measure the frequency of external signals and are often used to
measure speed by coupling a magnetic transducer to a toothed wheel or impeller-based flow rate
transducers.

• DUTY: The Duty Cycle function measures the percentage of time the CLK (clock) is high as a percentage of
I/O Signal
Description
Measures the positive or negative pulse depending on the signal type and
modifier chosen.
RST
Resets the counter to 0 depending on the signal type and modifier chosen.
ENB
Sensor starts measuring depending on the signal type and modifier chosen.
Determines what aspect of the pulse is counter (Up or Down) depending on the
the total time of the signal. The Duty Cycle function may be used to measure the percent ‘power’ or servo
control position being controlled by a PWM (pulse width modulation signal.
• DELAY: The Pulse Delay function measures the delay in time between Signal Line 1 (CLK 1) and Signal Line 2
(CLK 2) turning ‘ON.’ The Pulse Delay function may be used to measure the time between two signals
turning on or the phase angle of AC signals with suitable signal conditioning.
Counter Measurements
Duty Cycle = x/y%
CLK_A
DIR (Up/Down
only)
• CNT: The Counter function measures the number of OFF to ON transitions on the CLK signal. The counter
function may be used to measure the number of occurrences of an external event.
• U/D_CNT: The Up/Down Counter function measures the number of OFF to ON transitions on the CLK signal.
The Up/Down Counter function may be used to measure the number of occurrences of an external event or
the positioning of external devices based on a suitable transducer.

Appendix C: Troubleshooting and Help
Symptom: My XW-ED/XW-ED-PRO shows “OPEN” or “NaN” on the ZW-REC webpage.
Solutions:
• Check that the probe is connected properly, and the input connector is wired correctly.
• If using thermocouple short pins 2 and 3 together for Channel 0 and Pins 1 and 4 together for channel 1. If
the unit displays room temperature check your thermocouple for breaks.
Symptom: All my transmitters are missing after power cycling the ZW-REC.
Solution: On the ZW-REC System page make sure the “Enable Energy Scan at Startup” box is not checked. If
transmitters are set for long sleep times they will show up after they transmit next.
Symptom: Blue Light blinks on and off rapidly. XW-ED does not show up on the ZW-REC webpage.
Solution: Use Omega Sync to check that NID is the same as the ZW-REC and that the DID is not used by another device.
Symptom: Blue Light is on solid and reset button is not working.
Solution: Remove power, Batteries and Coin Cell from unit. Wait 5 seconds before applying power again.
Symptom: My transmitters sometimes appear as “Lost” on the ZW-REC webpage.
Solutions:
• Try to reposition your receiver or transmitter away from other wireless devices, microwaves, motors, and
other potential sources of interference. Make sure the antennas for all devices are pointed upwards.
• Try using a different RF channel that does not overlap with existing WiFi channels being used. All transmitters
must be power cycled after changing the RF Channel. (See ZW-REC User’s Manual).
