Table 13-1: XSeries
Indicator
Description
System
Low Lithium Battery Alarm: When LL (low lithium) is
displayed, the lithium battery voltage is below 2.5 Vdc. A new
LL
lithium battery measures approximately 3.6 Vdc.
Low Charger: When LC (low charger) is displayed, the
XSeries
LC
than or equal to the battery voltage.
Communication Protocols
Transmitting Data: Sending a response
→
Receiving Data: Processing request
←
Nak: Negative acknowledgement with packet list
!
Ack: Positive acknowledgement of receipt of request
+
Waiting for Ack: Waiting for response after transmission
Exception Alarm Processing
?
ID Recognized: Recognized and receiving request
Listen Cycle: Flashes if this remote port is active and running
Totalflow Remote Protocol. Flashes in sync with the listening
cycle that occurs at 1, 2 or 4 second intervals. When the baud
rate is faster than 2400, then the flashing symbol may not be
visible. The annunciator will remain on listening cycle if the
listen cycle is set to zero.
MODBUS® ASCII: MODBUS® ASCII protocol is selected for the
M
port assigned to this annunciator.
MODBUS® RTU: MODBUS® RTU protocol is selected for the port
m
assigned to this annunciator.
Local Protocol: Displayed when the PCCU32 port is active and
L
running Totalflow Local Protocol
¥
ID Recognized: The recognized ID is waiting for sync.
USB Protocol: Displayed when the USB port is active and
u
running the Totalflow Remote Protocol
Ethernet Protocol: Displayed when the Totalflow/TCP port is
n
active.
Measurement Applications
Back Flow Condition: Visible only when the DP variable is
BF
displayed
Zero Flow Condition: Visible only when the flow rate is
Z
displayed
H
Hold: Displayed when PCCU32 has entered hold
Alarm Condition: Need to view alarm. Compare application
A
limits to the current values to determine where the alarm
condition is present.
A to D Failure: Displayed if the A to D converter's absolute
AD
differential pressure, absolute static pressure, or temperature
status and alarm codes
