Overview
This section of the HW5 manual covers only the HW5 functions that are unique to the PF43x digital interface. HW5 functions that are not device dependent are covered in General HW5 feature.
Device Manager
The HW5 functions available for the HygroFlex are illustrated below:
To open the Device manager form, click with the mouse on Device Manager. The Device Manager form is used to configure the HygroFlex and to read device specific information.
When Device Manager is started, it automatically interrogates the device and downloads its current configuration.
Device Information
RS485 address: click on the underlined link to change the instrument address to be used in conjunction with an RS-485 network (multi-drop). Each network address should be unique and within the values of 0 to 63.
Note: the default factory RS-485 address is 0. Unless necessary, do not manually modify this address. HW4 will automatically change the RS-485 address of the device, if so required.
Device Protection: for a description of this function, see document General HW5 feature
FORGOT THE PASSWORD? - Power down the device. After powering up the device, you have about one minute to use the default password !resume! (include the exclamation marks). After one minute the default password will be no longer accepted.
The different sub-forms that are available within the Device Manager form are listed in a tree located on the left pane of the form. The number of sub-forms depends on the PF4 model (Device Type). To select a sub-form, click on it with the left mouse button.
Device Manager Menu Bar
The Device Manager menu bar is located at the top of the form.
File
The file menu is used to save to the PC, or to retrieve from the PC, the configuration settings of the device. The settings are saved in an XML file with the extension DAT. Saving the configuration settings to a file is useful for several reasons:
provides a backup when the device configuration has been changed in error
provides a means of quickly configuring a replacement device in the exact same manner as the original device
provides a means of quickly configuring a number of identical devices
Open: opens the device configuration folder specified in HW5 Global Settings - File Locations Tab - and displays all available probe and device configuration files (extension DAT). Select the appropriate file and click on Open in the explorer form. The contents of the configuration file are loaded to the Device Manager form. Review the contents of the Device Manager sub-forms. Click on the Device Manager OK button to write the configuration settings to the device or click on the Cancel button to leave the device unchanged.
Save As: saves the current configuration to an XML file with the extension DAT) in the device configuration folder specified in HW5 Global Settings - File Locations Tab. If so desired, any directory and any file type may be specified.
Tools
Firmware Update: This tool is used to update the firmware of the HF8 after downloading a new firmware file from the ROTRONIC website to your PC. Firmware files are given a name that shows both to which device the file applies and the version number of the firmware. All firmware files have the extension HEX or ROF. The ROTRONIC website will publish firmware updates as required. The tool opens a form that allows you to specify the folder where the firmware update file is located and to select the file. Click on OPEN to start the update process.
IMPORTANT: the device must be powered during the entire process. Loss of power when the transmitter is being updated may have unexpected results and prevent future operation of the device.
Generate Protocol: generates a Device Configuration Protocol. This text file is automatically saved in the folder specified in HW5 Global Settings - File Locations Tab. If so desired, any directory and any file type may be specified. This action is not recorded in the User Event file.

Temperature and other parameters: Left click on the arrow to the right of the text box and select the engineering unit.
Click with the mouse on the blue links labeled Metric or English to globally set the unit system for all parameters.
Note: regarding both HW5 and the transmitter outputs and display, the unit system selected for the transmitter overrides the unit system selected for the probe.
Differential Pressure
Description: Enter a description for this input (maximum 12 characters)
Unit: use the drop down menu to select the unit for differential pressure:
Pa
inH2O
mPSI
mBar
mmHG
mmH2O
Torr
g/cm2
Filter: enter the desired noise filtering level for the differential pressure measurement (0 to 13). The factory default is 0 (no filtering)
Simulation Value: place a mark in the check box to make the PF4 generate a fixed differential pressure value instead of the actual measurement.
The fixed value must be with the following limits: -999.99 and 9999.99
Note: Make sure that the fixed value falls within the range specified for the PF4 analog outputs
Using the PF4 as a simulator serves the purpose of verifying the analog signal transmission (loop validation) after completing an installation.
Alarm: use the mouse to check or uncheck the box labeled Alarm. When the alarm function is enabled, the PF4 generates an alarm when measurements are outside of the range defined by the Lo-Alarm and Hi-Alarm values.

HC2 probe
Probe Input
Description: enter here a description for the probe input (maximum 12 characters). This text can be displayed in the HW5 current Values tab.
Lo-Alarm, Hi-Alarm, Hysteresis: alarm conditions can be defined for humidity, temperature and the calculated parameter. Values that are below the low limit value or above the high limit value will trigger a digital alarm (there is no alarm for the analog output signals). The value specified under “hysteresis” is used for both the low and the high limits.
The HW5 will not show an out-of-limits value alarm by using red characters on the monitor screen anymore!
Note: The alarm will be only shown on the display of the device.
Monitor Probe Alarms: When the function is enabled, the device monitors the alarms generated at the probe level such as out-of-limit value and / or bad sensor alarm. When out-of-limit values have been defined both for the device and for the probe, the narrowest set of limits is used to trigger a digital alarm.
Calculation: based on the signals from the HC2 probe, the PF4 can perform psychrometric calculations.
