Page 8: Section 3 - Operation
Section 3 - Operation 3.1 CONTROLLER OVERVIEW The ACCUSAFE F901 Controller module provides detailed monitoring of the outputs from all connected F901B Sensor module(s). It provides real time display of gas concentration levels measured by all sensor modules in the network as well as alarm status, temperature (T) and relative humidity (RH) and a number of sensor related parameters that are detailed later in this section. - Page 9 ON/OFF BUTTON. PANELS LIST DATA DISPLAY FIGURE 3-1 NOTE: Turning any panel off disables it being displayed on the Sensor Measurement screen as well as turning off the data display on its Control Panel window as shown below. FIGURE 3-2 One exception to this layout is the PUMP CNTRL Panel which contains a slider controller for changing the value associated with the pump speed.
- Page 10 • One ENVIRO panel for each F901B sensor module that addresses Temperature (TEMP) and Relative Humidity (RH) at the channel’s location. These will be numbered sequentially for each sensor module in the system. See figure 3-3 below. • One SENS DATA panel for each F901B sensor module in the system. These panels provide data for real time raw sensor output, the current ZERO correction value and the current SPAN value.

Page 13: Alarms
3.1.4 ALARMS Any device created in a Control Panel can have a single associated alarm level that actuates an alarm indication on the Sensor Measurements screen. This will typically only apply to gas concentrations but could feasibly also be applied to environmental values. To access the Alarms menu and enable or set values for the alarms, touch the ALARM Icon as shown above. - Page 14 FIGURE 3-10 Email Alarm Notification settings screen FIGURE 3-11 Example Alarm Panel When alarm conditions are active, there will be a visual indication on the Sensor Measurement screen next to the sensor label as shown below (Alarm on H2S-2 channel). This will be accompanied by an audible beep tone from the controller module.

Page 15: Recipes
3.1.5 RECIPES The Recipes menu provides a programmable scheduler for properly configured control panels. This generally applies to panels the contain both a sensor and an actuator which is not the case for most instances of the ACCUSAFE system. As such, no recipe examples are provided for the purposes of this manual. - Page 16 FIGURE 3-16 FIGURE 3-17 Figure 3-17 above shows the Panel Configuration for the H2S 1 Panel. The field titled “Device Name” (circled in red) is the text that appears on the key viewing screens. This name can be changed to anything desired with a 24 Character limit (more characters can be input but other display elements may be impacted).

Page 17: Sensor Calibration
3.1.7 SENSOR CALIBRATION This menu provides access to all the Calibration options for each sensor module in the system as shown below in Figure 3-18. The Calibration procedures are detailed fully in Section 4 of the F901B Sensor Module User Manual. Refer to this manual for more regarding Calibration. FIGURE 3-18 3.1.8 INFO The INFO screen is shown in figure 3-19 below. - Page 18 The following parameters are displayed and/or accessed/changed on this screen: • Controller IP: The existing IP address for the F901 controller. • Software Version: The current software version. Software version can be updated via the LAUNCHER APP That accompanies your system on a flash drive. See section 4 on the next page for details on using the LAUNCHER APP.

You can now go to the Controllers list and highlight your controller as shown on the right. Once your controller is selected, click on the OPEN BROWSER button on the right side menu and the web browser window of your controller will open as shown below. - Page 22 • You can download data in intervals of one or more seconds, minutes or hours by checking the “Group by time (minutes)” checkbox and selecting the interval value and units value desired from the 2 dropdown menus circled below. Or leave the “Group by time” box unchecked to download ALL available data for the devices and time span selected.

Page 23: Cleanup Data
Generally, it’s best to download one set of data at a time (i.e. only select one data item from the list) as this will result in a cleaner dataset. 4.3.2 CLEANUP DATA Click the “Cleanup” button (red arrow in screenshot above) to erase all currently stored data as needed. -

NOTE 2: If you are editing the configuration currently on the controller, you can apply the changes to the target controller by clicking the Save button. The controller will briefly refresh and execute the new configuration. If the configuration is a local edit (no controller connected), the Save button will simply save the changes on the local file. - Page 25 • Enter the Username/Password of your cloud service account.
