How to use Config 3900 software

After double clicking the REGARD 3900 icon on the desktop the opening (default) screen is shown below.

Screen shot 1. The left window box shows the default setting of a control panel having four 4..20mA modules. The first module has its channels (CH1 to CH4) expanded. The right window box shows the details for channel one. At this stage the configuration PC is standalone and is not connected to an operational REGARD 3900.

Along the top of the tool bar we see the four words File, Configure , Language and Help. These are explained as follows File – (see screen shot 2)

• Open – allows a preconfigured file to be opened from a storage device i.e. hard drive

• Save – allows the opened configuration to be saved but with the option to give a new file name, location etc

• Save As – allows the opened configuration file to be saved, but with the option to give a new file name, location etc

• Print – prints the configuration even if ‘cancel’ is selected • Print Setup – allows the printer options to be selected without printing • Exit – closes the program, but first prompts to Save if not already Saved. If no

alterations have been made then ‘Exit’ will not prompt ‘Save’.

Configure – (see screen shots 3, 4, 5 and 6) Note 1: A RS232 CAN interface cable (4208785) is required to connect the PC with the REGARD 3900

• Send PC configuration to REGARD 3900 – this function uploads the entire configuration from the PC to the REGARD 3900 control unit (see Note 1 above).

• Receive configuration from REGARD 3900 – this function downloads the entire configuration of the REGARD 3900 into the PC (see Note 1 above).

• Compare system configuration to program – this function allows a comparison between the PC configuration file and that of the installed REGARD 3900. The differences will toggle; Blue bold text indicates system configuration whereas Black bold text indicates PC configuration.

• New configuration – this function allows a new configuration to begin. A second pop-up window (see screen shot 4) will allow the choice of modules before configuration commences. No connection to a REGARD 3900 is required.

• Copy Gas Channels – this function allows any configured channel to be copied and pasted into another channel allocation (see screen shot 5). No connection to a REGARD 3900 is required.

• Add New Board – this function allows new modules to be configured and the configuration stored ready for uploading into a REGARD 3900 (see screen shot 6).

Screen shot 6. When this function is chosen there must be a spare capacity within the configuration file or REGARD 3900. Otherwise the drop down menus will be ‘greyed out’ to represent no further configuration possible. If spare capacity exists within the configuration file then refer to screen shot 4 above and follow the instruction given there.

Screen shot 10.

Drop down menu for gas measurement units. Or type unique measurement unit to a max of 4 characters

Fault (F1). Enter value for fault threshold between 1mA and +3.8mA. This threshold trips the Fault relay on each input module and any subsequent configured relay (F1) on a relay module.

Fault (F2). Enter value for fault threshold between 1mA and +3.8mA. This threshold will only trip F2 relays configured on a relay module. A value of 0 (zero) switches this function ‘off’.



Screen shot 11.

Drop down menu for gas (FSD) measurement range. No custom measuring ranges are allowed.



Screen shot 12.

Option to set whether the alarm thresholds are rising or falling per alarm threshold

Enter A1 threshold between 4% and 100% of measuring range. Up to 2 decimal places are allowed subject to measuring range

Enter A2 threshold between 4% and 100% of measuring range. Up to 2 decimal places are allowed subject to measuring range

Enter A3 threshold between 4% and 100% of measuring range. Up to 2 decimal places are allowed subject to measuring range. A value of 0 (zero) switches this function

Adding into the system two relay boards (using the ‘New Configuration’ function) the following pages explain the function and configuration of each relay parameter.

Screen shot 14. The Explorer menu now shows two relay modules. Each relay module is expanded to show relays 1 to 16. Relay 1 has been selected. The first relay of each relay module is not configurable, therefore remains as a fail-safe, energised relay.

No configuration allowed for the first relay of each relay module.



Relay 2 has been selected and its configuration is displayed as ‘Common A1’. The A1 is selected from the drop down menu.

Screen shot 15. Common alarm means that any alarm in the system at the selected threshold will trip the selected relay.

Drop down menu for threshold selection

Click to receive individual relay configuration to the REGARD 3900



Relay 3 has been selected and its configuration is displayed as ‘Single A1’. The A1 is selected from the drop down menu. For single alarms to operate it is necessary to choose a single channel number. To do this select the channel number under the heading ‘channel’.

Screen shot 16. It is only possible to select a single channel from those which are not ‘greyed out’. The software automatically recognises the total number of available inputs.


Select individual channel for single operation



Relay 4 has been selected and its configuration is displayed as ‘Voted A1’. The A1 is selected from the drop down menu. The following information is required to set a voting configuration

• Threshold. • Total number of channels in the voting group. • The channel numbers of the channels in the voting group. • The number of channels to satisfy the vote from within the voting group.

Screen shot 17.


Select channel identity for those channels in the total voting group

Total number of channels in the voting group

Relay 6 has been selected and its configuration is displayed as ‘No Function’. No configuration is therefore needed. The relay 6 selection is ‘greyed out’.

Screen shot 18.

No configuration options

Relay 6 ‘greyed out’.



Relay 8 has been selected and its configuration is displayed as ‘Alarms Inhibited. No configuration is therefore needed.

Screen shot 19. Relay 8 will operate whenever the manual switch on the display board is switched to Inhibit. This gives warning that the control panel cannot generate gas alarms.

No configuration options



This page shows the ability to configure each individual relay, subject to it’s configuration as being

• Energise on alarm or Normally energised (failsafe) • Latching or Non Latching • Acknowledgeable or Non Acknowledgeable
