Space HMI Operation
Accessing Menu Configurations
The HMI allows the user to change parameters and options. The user may use the HMI to view operating information
regarding sensors, temperatures, pressures, and fault history on the HMI screen. There are four buttons to navigate
through the HMI screens.
NOTE: Buttons change functions during certain options and tests. Verify the screen and buttons throughout the
menu display.
The user can access the Top Menu HMI configurations by pressing the top two buttons simultaneously. To exit this
scre
en, simply press the ‘BACK’ button. When setting certain options or functions, pressing the ‘BACK’ button multiple
times will bring up the save screen. The user may select ‘YES’ to save the changes, select ‘NO’ to return to factory
settings or select ‘CANCEL.’ When selecting ‘CANCEL,’ any changes made will not be saved, and the screen will return to
the top menu.
The HMI menu system allows full access to every configurable parameter in the HMI. The parameters are factory
configured to the specific application. Parameters may need to be modified to fine-tune automatic operation after the
original setup.
Remote (HMI) Control Panel
On units shipped with a space HMI, a Cat 5 cable will need to be run from RTULink board J4 to J2 on the HMI. If
additional space HMIs have been added, they can be daisy-chained from the first HMI. An end of line resistor should be
added to the last HMI in the chain.
Space HMI Menu Structure
User settings : Allows the user to change or set certain temperature and configurations on the unit. Any changes within
this menu do not require a reboot to take effect.
Factory settings : Requires a password to enter this menu (1 1 1 1). These will be set job specific from the plant. Any
changes within this menu require a reboot to take effect. Upon exiting factory settings, if anything has been altered, the
board will reboot itself.
Service : Requires a password to enter this menu (1 2 3 4). Allows a certified technician to monitor the unit, and test
components in the system.
