The HMI
The Controller
When power is applied the HMI immediately starts up, displaying a “splash screen” with the Matelec logo and software
revision is displayed for several seconds. Once the splash screen disappears the HMI will then display the main screen
which gives an overview of the system.
While the HMI is operating it must always be connected to a controller in order to read the necessary data that it needs
to display. If it is unable to communicate with the controller the HMI begin to flash both indicator LEDS and notify the
user on the LCD. The user will be unable to operate the HMI until the communication link is restored.
During normal operation the user is able to access many different functions related to both the attached controller
and the Modbus interface. The following sections present the various menus used by the HMI and describe their use.
Navigation between the menu screens is performed using the left and right arrows, which cycles through each of the
screens in the following order:
1. Main screen (pump auto/off/manual control)
2. Alarms
3. Input and 4-20mA states
4. View logged data
5. Reset logged data *
6. View functional parameters
7. Edit functional parameters
8. Edit configuration settings *
9. System information and serial number *
* Lines marked with an asterisk require entry of a PIN number for access.
Note that many of the menu screens feature a prompt along the bottom of the display which outlines basic button
functions.
1.1 Main Screen
The HMI main screen provides the overall system status and allows the user to change the auto/off/manual settings for
each pump. Pressing “OK” while on the main screen will allow the user to select the mode for both pumps, as shown in
the image on the right:
1.2 Alarms
The alarms screen reports any alarm conditions and provides the user with a method to reset them. If there are no
alarms active then the screen will appear as shown on the left image. This provides an opportunity for the operator to
trigger an alarm test. Pressing the OK button will cause the controller to activate its siren and strobe outputs, plus all
LEDs on a keypad (if used) for 5 seconds. After this alarm test completes the alarms will return to normal operation.
During pump mode selection the mode of the selected pump (AUTO,OFF or MANUAL) will flash. Pressing the up and
down buttons will change the mode of the selected pump, whereas pressing the left and right buttons will select the
pump. Pressing OK will accept the selection and return to the main screen.
