7. If there is interference on the “hop sequence” channel you have
selected, change to another channel. There are six channels to choose
from. Both ends must have the same channel number. The system does not
need to be powered down to change the channel #. However, it will not
communicate while the channel numbers are not identical.
8. The system’s maximum reliable transmission distance will change with each
installation since it is dependent on all of the environmental and electrical factors
of each particular installation. While the distance is nominally specified as up to
5,000 feet, it may not work at the full range in some installations.
9. The Transmitter base unit is designed for mounting inside another control
cabinet or enclosure appropriate and suitable for the particular application. If a
NEMA 4X enclosure is required, order SSI P/N: 05000-47001A for the NEMA 4X
Fiberglass 12” x 10” x 4” enclosure option. This option includes an interior
mounting plate that the PRT-16 or PRR-16 mounts onto.
Troubleshooting Procedure:
Check all wiring connections especially the control cable connections between
each Radio/Antenna unit and its respective Base unit.
Check that power is on and applied properly to all components.
Check the RED LED on the Transmitter and Receiver/Antenna boards and make
sure they are flashing in fast mode.
Check to make sure that all Transmitter and Receiver units are both on the same
channel (Dip Switches #1-3)
Make sure that there is not another system operating in the same RF airspace
that has the same channel hop sequence selected.
Make sure that the Transmitter and Receiver are set for the same Input and
Operational Mode, Form A (2-wire) or Form C (3-wire). (Dip Switch #6)
Check Red LED’s on each Base Unit’s input or output, and make sure they are
flashing with pulses received from the meter.
Use the Signal Strength LEDs (RSSI) on the Receiver to measure signal
strength. Put Dip Switch #7 in the UP position on the Receiver to enable the
RSSI indicator. Put in DOWN position when test complete to turn off RSSI.
Do
not leave the RSSI indicator on during normal operation. Pulses will be
lost if the RSSI is left on. The RSSI is a diagnostic tool only and not for
normal operation.
Check that the antennas are securely screwed to the Radio/Antenna board.
Use an ohmmeter or continuity checker across the KY terminals of each output
and determine whether each is opening and closing by watching the output’s
resistance change. When the output is open, there should be infinite resistance.
When the output is closed, the on-state resistance should be approximately 18 to
25 ohms.
