& TROUBLESHOOTING
• Place the appropriate (Normally Open) NO or
(Normally Closed) NC jumpers (both included) in
position-RED wires = NO-ON=Closed and BLACK
wires=NC-On=Open
Utility Meter Pulse Transducer Module - SEQ100
• Verify all wiring prior to powering the QWL 3.1 Rev
3 Series Panel and SEQ100.
• Take note of the current readings for all meters.
Since the SEQ100 is used for only monitoring, and
is the reading appear to be correct, you are done.
• If a value does not appears to be correct, verify on
the programming page the value programmed in is
correct.
• If a value is shown as 0 (Zero) the SEQ100 is not
receiving a pulse signal.
Site Communications Center - QD2040
• Be sure to verify all wiring and programming
information before hooking up to Network
• If the CPU LED does not light up, verify that the
power supply nodule (included with the QWL 3.1
Rev 3 Series Panel) is plugged in to an outlet that
has power.
IF
THEN
Check that the baud rate set on the controller(s) are all
set the same. Verify controller address.
Rx LED is always on. This is typically a problem with
wiring.
Check wiring. Make sure that communication wiring
runs are at least 5' away from fluorescent lights, motors,
etc. Make sure that all controllers on a network have a
unique address.
Make sure that the "A" and "B" wires are not switched or
shorted. Make sure that there is no stray voltage on the
"A" and "B" wires. "B" to "A" should measure between
0.5 VDC and 3.6 VDC. "B" to "A" should measure 0
VAC. "A" to "Shield" and "B" to "Shield" should measure
0 VAC and 0 VDC.
Both Tx and Rx LEDs will blink. Both the computer and
the controller are responding, but you still receive com-
munication errors.
Tx LED blinks, Rx LED is always off. If this happens,
the computer is sending, but the controller is not
responding.
On smaller networks, try removing one of the two
terminating resistors.
