9. INSTALLATION
9.1 INPUT
The logger has 8 input channels. You can configure the type of signal to be read by each channel. All types of input channels accepted are factory calibrated and no further adjustment is required. The user defines and configures the channels that will be in use, and disables the others. The types of input channels accepted by the logger and their maximum ranges are listed in Table 01.

MEASUREMENT INTERVAL
The speed of input channels readings depends on the number of channels enabled and type of input programmed for each channel. Each channel requires a reading time of about 50 ms. Programmed channels with Pt100 input need m ore than 50 ms for cable length compensation calculations. 150 ms are required for internal processing, regardless of the number of channels enabled. Thus, if only one channel is enabled, readings will take place at every 200 ms (50 + 150). If this channel is programmed to Pt100, 250 ms are required between readings (50 + 50 + 150). Required time to read the eight channels is 550 ms. If they are configured as Pt100 input, required time will be 950 ms.
9.2 OUTPUT
The logger has two relay outputs (ALM1 and ALM2) that can work as Alarm or Digital Output. When configured as Alarm, they act as configured by the user. As Digital Outputs they are remotely controlled through serial communication.

9.3 ALARMS
The logger has two alarms (Alarm 1 and Alarm 2) that work independently. Each alarm has a setpoint that defines the triggering point. They can act as Low alarm or High alarm. Low alarms are triggered (turn on an output) when the value read by the input channel is below the setpoint value. The High alarm is triggered when the value measured is above the setpoint value. Alarm outputs can be associated to ALM1 (relay 1) and ALM2 (relay 2). The same alarm can be associated to both outputs. Such settings must be defined for each of the eight input channels.
9.4 SETUP
It is necessary to configure the logger before starting operation. It is necessary to define the working mode assigning values to a series of parameters. The register is provided with the Configurator software. It provides the parameters that define how the logger will work. The software is supplied on CD The installation on the user’s PC is performed through the FL_Setup.exe application.
MINIMUM REQUIREMENTS
To obtain a good performance of the Configurator software, the PC must support the following requirements:
Pentium III (or equivalent) or higher.
Windows 98® or higher.
A free serial port to support the communication with the register.
The system will perform better in computers with higher specifications. A RS485 (serial or USB) converter will be required.

RUNNING THE LOGGER
Before running the Configurator the logger must be connected to the computer. Use the free serial port, a RS232 / RS485 or USB / RS485 converter and suitable cables for the connection.
Figure 1 – Overview of the communication system
Note: The logger basic configuration is factory set (communication address 1, baud rate 9600, no parity, etc). The first configuration must be accomplished in a point-to-point connection with the computer. After it is configured with a specific
communication address, among other parameters, it can be installed in a communication network together with other devices. When you try to run the Configurator software there is an attempt of immediate communication with the connected logger. If communication is successful, the Configurator is fully loaded and the logger configuration is read and displayed. Settings are then allowed to be changed. In case there is a communication fault, only the communication screen is loaded. It displays the communication parameters used in communication attempts. Selected serial port, baud rate, address and parity. For a new communication attempt, the user must:
Check connections;
Check if the serial port displayed in the communication screen is the same as the selected one;
Check if the serial port selected is really free in the computer;
After checking those items, press Search in the Automatic Search (valid only for a point-to-point connection). If communication is successful, the Configurator software is fully loaded.

USING THE LOGGER When the logger and PC are connected, the Configurator is fully loaded. Four screens are available: Communication, Channels,
Acquisitions and Diagnosis; which can be selected in the upper tabs. CHANNELS SCREEN
In the channels selection screen, the user defines features for each channel, such as: input type, alarms, scale etc. Functions displayed are:
Figure 2 – Channels screen
Title – Defines a name for the logger (up to 16 characters). Channel selection – Selects the channel to be configured. Information presented/defined in the remaining fields for this screen are
related to the channel selected. Define channels that will remain active or enabled while the logger is operating in this field. It is also possible to assign names to the input channels (up to 8 characters).
Input Type – Defines the input type for the channel selected in Channel Selection. Options are displayed in Table 01. Measurement Unit – Defines the measurement unit to be used. For temperature sensor input, options are ºC or ºF. For 4-20 mA
and 0- 50 mV inputs it is possible to write the required unit. Scale – For 4-20 m A and 0-50 mV input types it makes possible to make an indication scale, with the upper and lower indication limits. For the other input types, the logger use a preset scale. Decimal – It defines the number of decimal points to be displayed in scales configured for channels with 4-20 mA and 0-50 mV inputs. Decimal point – When the channel is configured as thermocouple, it is possible to choose how values will be displayed: with or without the decimal point. ALM1/ALM2 – It makes possible to define if ALM1 and ALM2 will be used as Alarm or Digital Output. As Alarm, it is triggered as defined in Alarm 1 and Alarm 2. In Digital Output, triggering takes place only through serial communication commands (Preset Single Coil). Alarm 1/Alarm 2 – After the alar m outputs are defined, the user defines alarm Set Points in these fields; as well as the working mode as Low or High. It also defines which output will be connected to the alarm. The association between an output and alarms 1 and 2 is not required, but the alarm activities will be indicated in the Holding Register 0008, and will be available to be read through serial communication.

ACQUISITIONS SCREEN
Parameters related to how and when readings take place are defined in this screen. Acquisition is the operation of reading and registering in local memory the process variables (temperature, pressure etc) present in the input channels enabled. Among parameters are acquisitions start and end of readings and time interval between acquisitions. In models without local memory, aimed only at measuring and making them available in the supervisory software, this screen will not be enabled. The acquisition screen parameters are:
Figure 3 – Acquisitions screen
Acquisitions start – There are 3 options to start acquisitions in thelogger:
1. Specific date and time. Day, month, year, hour, minutes and seconds are defined. When they are reached they start reading signals from the input channels of the logger.
2. Digital input (DI) activation. In this mode, acquisitions start whenever the DI is triggered and stop when it is disabled.
3. Through Start button – Determines that acquisitions start when the Start button is pushed from the screen. In this option, observe that settings must be already configured and applied to the logger.
Base Interval Between Loggings – Defines the minimum time interval between acquisitions. It can be from hours up to tenths of seconds and it is common to all channels. However, a multiplier of the base interval can be defined for each active channel. Interval multiplier – Readings can be taken in different times for each channel, a base interval multiplier is defined for each channel. The multiplier can be defined between 1 and 255. Example: For a base interval of 10s, the logger will record at every 10s the value measured in channels programmed with multiplier equals 1. At every 20s in channels with multiplier equals 2,… Acquisition end – Defines the acquisitions end. Options are:
1. Specific date and time. Day, month, year, hour, minutes and seconds are defined. When they are reached they stop acquiring values from the input channels of the logger. Note: Acquisitions can be stopped before the preset period is reached by pressing the Stop Now button or when the full memory capacity is reached.
2. Stop after a defined number of base intervals is reached. Note: Acquisitions can be stopped before the expected acquisitions number is reached by pressing the Stop Now button or when the full memory capacity is reached.
3. Never stop (wrap around). Acquisitions are taken continuously. When the full memory capacity is reached, older information are replaced by new ones. The process is only interrupted if the Stop Now button is pressed.

4. Full memory. Acquisitions end when the full memory capacity is reached. Pressing the Stop Now button also ends acquisitions.
The Acquisitions screen has also an important group of information about the logger and acquisitions:
Current Time: Displays current date and time used by the computer. Logger Time: Displays current date and time used by the logger. Logging Available Memory: Displays the total memory capacity for the logger. Programmed Number of Acquisitions: Indicates the number of acquisitions that will be performed and logged in memory. It is also
possible to check the number of acquisitions per channel enabled.
Programmed Number of Base Intervals: Informs the minimum interval between programmed acquisitions Estimated time: Informs time required to complete the programmed acquisitions.
After setting up the logger and estimating possible implications, the user must send the configuration to the logger. Press Apply. To send and leave the configurator software, press OK. To leave the configuration without sending to the logger, press Cancel.
Note: When the new configuration is sent, the logger time is updated, adopting the computer time (date and hour). COMMUNICATION SCREEN
This screen is showed even when there is no communication between logger and computer. It provides parameters related to system communication. Its fields are:
Host Parameters (HP) – Provides a choice for the serial communication port to be used. Network Operation – Makes possible to define a new communication address and baud rate for the logger. Define values and press Change. If connected, it makes possible to read the complete configuration of a given logger. It is only necessary to select the required address and press Read Configurations. The configurator starts to display the selectedlogger configuration on the screen. Parity – Makes possible to define parity used in serial communication. The number of Stop Bits as recommended by the Modbus
standard depends on parity. When parity is configured as none, 2 stop bits are used; when parity is configured as Odd or Even, 1 stop bit is used.
Note: Baud rate and parity must be the same for all the network elements. Automatic Search – Makes possible to search the connected logger communication parameters, in a point-to-point communication,
testing all possibilities of addresses and possible transmission rates (baud rate). After the parameters are found, they are displayed.

9.5 INSTALLATION
The logger has two terminal lines for input connections, power supply, backup power supply (VBAT), digital input and serial communication.
INSTALLATION RECOMMENDATIONS
Input signal leads must be installed in grounded conduits and away from power or contactor wires.
Instruments must be powered only by an exclusive power supply.
Installing RC filters (47W and 100nF, serial) is strongly recommended at contactor coils or any other inductors.
System failure should always be taken into account when designing a control panel to avoid irreversible damage to equipment or
people. The ALM1 and ALM2 output relays, used as alarms, do not warrant total protection.
Wires section: minimum gauge 0.14 mm².

ELECTRICAL CONNECTIONS – POWER SUPPLY
Terminals 19 and 20 identified with POWER show the main power supply of the logger. As a backup power supply, in VBAT, terminals 14 and 15, an extra power supply of +6 to +24 VDC can be connected so that the device can continue measuring and logging operations in the failure of a main power supply.
While using the VBAT supply the logger can not use the serial communication and does not trigger ALM1 and ALM2 outputs.
ELECTRICAL CONNECTIONS – ALARMS AND DIGITAL INPUT
ALM1 and ALM2 outputs, terminals 21, 22, 23 and 24, correspond to relays used by alarms. NA contacts are available, with load capacity of 3 A / 250 V. A dry contact device should be used (switch, relay etc) in digital inputs, terminals 13 and 14. When the contact is closed, the digital input is triggered. Notice that when a digital input terminal is common to the VBAT negative it can be concurrently used to both ends.

10. OPERATION
After configuration and installation the logger is ready to use. When you turn on the logger, the LOGGING indicator flashes in the front panel, this indicates that the logger is operating properly. It will flash once at every 2 seconds when it is not logging and twice at every two seconds when logging. Acquisitions start and end according to what was defined during configuration. The speed of input channels readings depends on the number of channels enabled and type of input programmed for each channel. The logger starts readings immediately after it is turned on. Current values found are temporarily stored in internal registers. The logger sends the content of its internal registers when the supervisory software requires. In the front panel there are two indicators that show when the logger is communicating with the external world. When the Rx indicator is turned on, it means that the device is receiving data; the Tx indicator shows that data ar e sent outside through serial interface.
ACQUIRED DATA COLLECTION
For the collection of data logged in local memory, it is necessary to use FieldChart or Superview software, or to build an application in a supervisory software whose version supports the specific driver.
10.1 SERIAL COMMUNICATION
The logger has a master-slave asynchronous serial communication interface RS485 to communicate with a supervisory computer (master). The logger is always the slave. Communication always start with the master, which sends a command to the slave address with whom it wants to communicate. The addressed slave undertakes the command and sends the corresponding answer to the master. The logger also accepts broadcast commands. Note: Recommended cables for serial communication are 3 x 24 AWG (3 x 0,25mm
2
)+ shield. This way the shield can be grounded
while cables are used for signals.

NOTES ABOUT REGISTERS
Registers 00 to 07:
They keep the continuously updated value of readings from their respective input channels. The speed of such update depends on the number of channels enabled and the input type selected for such channels. As the register is constantly scanning inputs, the higher the number of active channels the higher the number of inputs that will be read until the device reads the same channel again, decreasing the update speed. Besides, channels configured as Pt100 are read twice each, as part of a compensation algorithm of the cable resistance. In cases where there is only one active channel (no defined as Pt100), this channel is updated at every 0.2 seconds (best rate). In the case of eight Pt100 channels (worst rate), complete scanning of channels takes 0.95 seconds. The signal of the value read is represented as complement of 2. In cases with resolutions in tenth of degrees, such as Pt100 and thermocouples, the value is read without the decimal point (multiplied by 10), for protocol constraints. The same way, the decimal point is disregarded in linear inputs (4-20 mA e 0-50 mV).
Register 08:
Reports if there is an alarm event in some of the channels and if the event corresponds to a Low or High alarm. Byte High:
Byte Low:
Registers 10 to 13
Report A/D conversion errors. byte high -> odd channel:
byte low ® even channel: Same as byte high for the adjacent channel.

Registers 14 to 16
Only valid when FieldLogger has a real-time clock (model with memory) byte high: Second (Reg. 14), hour (Reg. 15) or month (Reg. 16) device currencies. byte low: Minute (Reg. 14), day (Reg. 15) or year (Reg. 16) device currencies. Year is always based on the number 1998. Thus, if the value logged is 9, in fact the current year is (1998 + 9 =) 2007.
Registers 17 to 24:
Deal with the current configuration of their respective channels, more specifically about the type of input, engineering unit for temperature sensors (Pt100 and thermocouple), channel acquisitions enablement, option of differential input (sensor between two inputs) and type of alarm triggering.

TRIGGERING DIGITAL OUTPUTS
The Modbus command available to enable and disable outputs (provided they are configured as digital outputs) is the following: 05 – Preset Single Coil (Writes in Digital Outputs)
The ALM1 output corresponds to the output point address 0. The ALM2 output corresponds to the output point address 1.
COMMUNCATION FAULT
In case there is any communication issue with the device, please check the following items:
Is the device correctly energized?
Is the serial cable tightly connected? In negative case, connect it in the appropriate form.
In Configurator, the communication port selected corresponds to the port to which the register is connected? In case it does not
match the right port, select the correct one.
Is there any other software using the required communication port in the computer? In positive case, close the software and try
to communicate again. If none of the above steps manage to solve the problem try to:
Run the “Automatic Search” option, and check if there is not more than one register connected to the network.
Use other serial port from PC.
Install the Configurator in another PC and try to repeat the steps indicated above
