Indicator Description
System
Low Lithium Battery Alarm: When LL (low lithium) is displayed, the lithium battery voltage is below 2.5 Vdc. A new lithium
LL
battery measures approximately 3.6 Vdc.
Low Charger: When LC (low charger) is displayed the µFLO
LC
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.
M MODBUS® ASCII: MODBUS® ASCII protocol is selected for the port assigned to this annunciator.
m MODBUS® RTU: MODBUS® RTU protocol is selected for the port assigned to this annunciator.
L Local Protocol: Displayed when the PCCU32 port is active and running Totalflow Local Protocol
¥ ID Recognized: The ID has been recognized but is waiting for sync.
n Ethernet Protocol: Displayed when the Totalflow/TCP port is active.
Measurement applications
BF Back Flow Condition: Visible only when DP variable is displayed
Z Zero Flow Condition: Visible only when the flow rate is displayed
H Hold: Displayed when PCCU32 has entered hold
Alarm Condition: Need to view alarm. Compare application limits to the current values to determine where the alarm
A
condition is present.
A to D Failure: Displayed if the A to D converter's absolute differential pressure, absolute static pressure, or temperature
AD
readings exceed the maximum counts or are less than the minimum counts
Display applications
1 A number represents the Display Group number currently being displayed.
↑ The displayed item's value is above the Data High Limit value that is specified on the display Item Setup screen.
↓ The displayed item's value is below the Data Low Limit value specified on the display Item Setup screen.
