Insert a new battery taking note of the proper orientation as shown in
Figure 3.3
.
The positive battery terminal contacts the large terminal and faces towards the top of
the ZW-ED.
Line Power
The ZW-ED may also be powered using line power. The Power Connector can
accept 5V
DC
to 36V
DC
and 24V
AC.
An optional Safety Qualified AC adaptor
1
is available
to simplify installation. If you are supplying your own power for the ZW -ED, a M8 Field
Installable Connector is available. A soldering iron is required to use the M8 Field
Connector. Refer to
Figure 3.4
for the correct wiring for the ZW-ED.
Figure 3.4- Power Connector
To install an external power connector, first remove the dust cap on the ZW-ED
Power Connector. Align the sockets in the connector with the pins on the ZW -ED. Insert
the connector and rotate the metal knurl clockwise while holding the connector body
steady. Ensure the connector is tight. The connector should be firmly mated to maintain
NEMA 4 ingress protection. Some exposed threads are normal when the connector if
mated.
Caution:
Do not rotate the body connector. Do not use pliers, vice grips or other
tools. Hand tighten only.
Start Up and Enumeration
The ZW-ED starts automatically when power is applied. On power up, the ZW -ED
reads the Network ID and Device ID, detects any connected sensors, and establishes a
link to the Receiver. The blue link indicator LED flashes while the ZW -ED searches for a
Receiver. Once communications are established, the LED will flash quickly and turn off.
The LED will flash again each time a new reading is transmitted.
If the LED does not stop blinking it indicates the ZW -ED cannot establish a
connection to the Receiver. Check that the Receiver is on and configured correctly.
Check that the Network ID on both the ZW-ED and the Receiver are the same. After
making any changes, press the Power Button on the top of the unit to reset the ZW -ED
and force it to rescan for the Receiver.
Once a link has been established, close the lid of the ZW -ED and tighten the lid
screw. To maintain a NEMA 4 rating, make sure the lid is flush with the body and does
not show any gaps. The ZW-ED is now ready for use. Refer to your Receiver user
manual for instruction on how to view readings, change the measurement frequency
and log data.
