PCAL  
(applicable only to the MilliVolt sensor type )  This pressure calibration value 
represents  the number of millivolts at full range.  This value is unique for each 
sensor, and sometimes is referred to as Full Scale Detection  (FSD). 
Custom Offset 
(applicable only when measuring pressure, height, or depth)  This field 
indi cates the offset added to all readings.   For example, enter the appropriate 
value to add to all pressure values to compensate for ground level.  To remove 
an amount from every reading, simply enter the value as negative.  
Electrical Range 
(applicable only t o voltage or current data types )  These fields represent the  
electrical range corresponding to the voltage or current, as applicable.   Enter 
or use the up/down arrows to designate  a range up to 20mA for current.  
Select 0 -2V, 0- 5V, and 0- 10V for voltage .  
Physical Range  
(applicable only to the  current or voltage sensor type )  These fields represent 
the range of the sensor input  corresponding to the voltage .  For example, 
consider an input of 4- 20mA involving a temperature sensor where 4 mA 
represents 0 degr ees and 20 mA represents 100 degrees.  This would require 
entering the values 0 and 100 in  the Physical Range  fields.  Enter the values 
manually or use the up/down arrows. 
Logging Interval  
This drop- down list includes the options for se tting  the measurement interval 
at which  to log data on this channel.  Options available range from 1 second to 
24 hours.  The  data logged on th is channel represent s averaged data ( based on 
the number of samples taken).  XiLog+ records the averaged data and daily 
minimum and  maximum values for the channel.

Send Data Reports  
Selecting this option ensures the logger sends data reports by SMS or GPRS  
based on the frequency selected for remote data reporting.   
T he minimum logging interval for data sent through SMS is 1 minute.  
Ac tivating SMS reporting for data based on a shorter logging interval  requires 
averaging the  data at a 1-minute interval before being sent . 
Note:  Sending data logged at an interval of less than 15 minutes 
through SMS  requires sending more than one SMS per day for each 
channel.  For example, sending 1- minute SMS data every day requires 
sending 15 SMS per channel per day. 
Secondary Logging Interval 
Some XiLog+ models allow a secondary logging interval for logging the same 
channel input at a second rate.  This data can be reported remotely, or logged 
internally and remotely requested (as required).

Digital Channel  
 
This window includes the parameters for setting up digital channels.  The 
presence of a green  dot to the left of the channel name indicates the ch annel is 
enabled and recording data.  
Enable 
Selecting this checkbox enables  the channel on the logger.   Not all channels 
on a logger must  be enabled when the logger i s in use.  Disabled channels do 
not use power. 
Sensor  Profile/Sensor  Type 
The Sensor Profile  drop-down list contains the options for selecting t he kind 
of digital sensor that  will be attached to the logger.   If the appropriate sensor is 
not available in the list,  select the Custom option and then select the 
corresponding sensor type  from the  Sensor Type  list.  Each  digital channel 
can receive two pulse inputs .

Several options also are included in the Sensor Types  drop-down list for 
performing event logging using digital sensors.  To  implement event logging, 
select one of the corresponding options from the list.  
Pulse Direction 
This drop-down list contai ns the options for specifying how a bidirectional 
sensor  indicates reverse flow.  
Logging Interval 
This drop-down list includes the options for designating the measurement 
interv al at which  to log data on this channel.   The o ptions available range 
from 5  seconds to 24 hours.  The  data logged on the channel represents 
averaged data (based o n the number of samples taken).  XiLog+ records the 
ave rage d data and daily minimum and maxi mum values for the channel.  The 
digital channel als o records daily volume.  Transmitting the meter reading 
from the site to the logger, as be low, will ensure remote tracking of the site 
meter reading  is accurate.  
Units 
This drop- down list contains the options for selecting the units of measure in 
which to log  the data. 
Continuous Power  
Selecting this checkbox ensures the channel provides  uninterrupted power to a 
pulse (sensor) unit that requires continuous power .  Use this option only when 
the required by  the sensor type. 
Combine Flows  
Selecting this checkbox adds together the flow totals from  a combination 
meter, which represents two meters (larger and smaller) working in parallel, 
before the data is transmitted to the logger  to provide one flow rate and meter 
reading .  In this scenario, flows exceeding  a certain rate will flow through the 
larger  meter and flows occurring below  a certain rate will flow through the 
smaller meter.   The outputs from both meters connect to the logger on two 
different pulse tra ins of a single channel.  
						

							ADS XiLog+ System User Manual

If this option is not selected, the flow rates from the two meters will be logged 
and transmitted independently.  Therefore, transmitting the data via SMS will 
result in sending  double the number of SMS. 
Send Data Reports  
Selecting this checkbox ensures the logger send s data reports by SMS or 
GPRS , based on the interval  designated for remote data reporting.  
The minimum logging interval for data sent through SMS reporting is 1 
minute.   For data logged at a shorter interval, the logg er will average the data 
at a 1 -minute interval before sending the report . 
Note:  Sending data logged at an interval of less than 15 minutes via 
SMS requires sending more than one SMS per day for each  per 
channel.  For example, sending 1 minute SMS data every da y requires 
sending 15 SMS per channel per day. 
Calibration Factor  
This field represents the number of liters that correspond to a single pulse 
from  the meter .  This value should always reflect the factor set in the meter.  
Mo dify this factor manually  or using the up/down arrows. 
Meter Reading 
This field displays the site meter reading  entered into the logger.  Writing this 
reading  into the  logger upon installation  will ensure the meter reading in the 
XiLog+ track s the actual meter reading.   Enter a meter reading up to 10 digits 
in length , with an  accuracy of up to 4 decimal places.  
Meter Units 
This drop-down list includes the options for selecting the units of measure 
corresponding to t he meter read ing.  A variety of units  are available, based on 
the s ize of the meter and accuracy required.  
Secondary Logging 
Some XiLog+ models allow a secondary logging interval f or logging the same 
channel input at a second rate.  This data can be reported remotely, or logged

Alarm Configuration  
 
Al arm Configuration  sub-window  
Alarms may be setup  independently for each channel of the logger.   Three 
types of alarms  are available:  threshold, profile , and envelope alarms. 
Enabled 
Selecting this checkbox activates the alarms for this channel.  
Profile Mode 
 
Profile Mode  menu options  
This drop-down contains the options for selecting the kind of alarm to 
generate from the XiLog+  under certain threshold conditions  for a channel.  
The following sections provide information on the individual alarm modes 
and de scriptions of  the corresponding parameters that must be configured for 
the alarms.  The Common Alarm Configuration Parameters  section includes 
the descriptions for those parameters that are applicable to all three alarm 
modes. 
Common Alarm Configuration Pa rameters

   Deadband  (applicable only to Threshold and Profile alarms)  
This field displays the deadband value around the threshold.  The logger will 
generate a high alarm when the channel reading exceeds  the High Threshold 
plus the deadband.  The alarm clears when the channel reading falls below the 
High Threshold  and the deadband.  For example, entering a high threshold of 
0.456 mgd and a deadband of 0.023 mgd will trig ger a high alarm when the 
flow exceeds 0.479 mgd and clear when the flow falls below 0.434 mgd.  This 
prevents the system from generating multiple alarms at locations that 
experience flows that may oscillate around a threshold value.  
If this feature is no t relevant or required, enter a deadband of 0. 
Note:  While the deadband value always represents an amount  when 
establishing a T hreshold alarm,  the deadband can represent either a n 
amount or a percentage when using  Profile alarms.  To indicate that 
the val ue in the Deadband field serves as a percentage, select the 
Deadband is percentage  checkbox after entering the value.  
 Debounce Delay 
This drop-down list contains the options for selecting the debounce delay, 
which represents the amount of time the flow mus t remain above the 
designated high threshold (and deadband) or fall below the designated low 
threshold (and deadband) before the system generates an alarm.  Delay options 
range from 1 to 60 minutes.  For example, when selecting a debounce delay of 
5 minute s, the flow must remain above the high threshold (plus the deadband) 
for at least 5 minutes before the system will generate a high alarm.  
Note:  The debounce delay applies only when initiating alarms.   It is 
not designed for use in determining whether an alarm has been cleared.  
 Alarm Reporting 
 
Reporting method options  
Alarm reporting can occur through SMS or FTP (or both), and each alarm 
trigger can be setup to occur through a different reporting method.  Delivery 
methods for alarms are independent from t he delivery selections for collecting 
logged data.  For example, logged data can be sent via FTP and alarms can be 
sent via SMS.

Threshold Alarms  
Threshold alarms generally involve designating a high and/or low threshold 
beyond or below which the XiLog+ wi ll generate an alarm.  This section 
includes descriptions for the parameters that are common only to threshold 
alarms.  
  Low Threshold 
This field represents the threshold below which the logger will trigger a low  
alarm.  Enter the threshold manually or use t he up/down arrows. 
  High Threshold 
This field represents the threshold above which the logger will trigger a high 
alarm.  Enter the threshold manually or use the up/down arrows. 
Profile  and Envelope Alarms  
Profile and Env elope alarms  are more complex alarms  that involve  
designating a different threshold value for the high and low alarms for every 
15- minute increment throughout the day .  For example, the h igh thresholds 
designated  for generating flow alarm s may be much lower through the night 
than during the da y.  
Selecting  either option displays a graph  for creati ng and editing the profile or 
envelope. 
 
Importing sample data from the database 
The simplest way to  establish a profile or envelope alarm is to import 
historical data from the site  in the following way: 
1.  Select the appropriate logging function from the A vailable Data list.  
2.  Select the radio button corresponding to the option for the number of 
days for which to import data. 
  Single day   Choose this option t o import data for only one day, 
and then designa te the date for which to import the data using the 
Start Date  calendar control.
