Run test: Automatic motor starting is activated by the run test pushbutton.
Alternating current failure: (Optional) Alternating current failure will count the time following an AC Failure and at the
end of a predetermined time, will start the engine with an AC FAIL request.
A red rectangular box will indicate the reason why the engine is not running despite the fact that a request is being
made. Possible choices include, but are not limited to:
Overspeed: This start cause happens when the controller receives a request to start, but the engines sends an
overspeed signal, thus preventing its ability to effectively start the engine.
Fail to start: This start cause happens when the controller receives a request to start, but a “Fail To Start” alarm is
active after a cranking sequence failure, thus preventing its ability to effectively start the engine.
Low zone not running: A not running lower zone controller prevents the motor from running. This functionality is
optional.
Locked: An interlock signal is preventing the motor from running.
N: Operations timers: This includes the sequential start timer, the run period shutdown timer, the manual test timer,
the weekly test timer and the alternating current failure timer.
O: The pressure gage: It allows for a precise reading of the actual system pressure. The cut-in and cut-out are
represented by a red and green line on the gage, allowing a quick comparison between the actual pressure and the
set points. At the center of the gauge, a digital indicator shows the actual pressure represented also by the needle
of the gauge. Just under of the digital pressure indicator, the actual pressure unit is shown. The maximum allowable
pressure is also indicated on the gauge and will scale the gauge accordingly.
P: HOA Indicator: Displays the current mode. Hand, Off, Automatic.
Q: Actuation Mode: Displays if the controller is Pressure Actuated or Non-Pressure Actuated.
R: Controller type: Displays if the controller is an Automatic or Non-Automatic type.
S: Shutdown mode: Displays if the shutdown on this controller is Automatic or Manual.
P-Q-R-S: If an alarm or a warning is active, a colored rectangle will appear at the bottom of the screen and will
display the error message. This notification will be yellow for a warning and red for an alarm. If more than one error
is active, the display will alternate between the error messages. The messages will disappear when the alarm or
warning starting cause is no longer present.
After 5 minutes of inactivity on the ViZiTouch, the screen will dim it's brightness to 25%. After 10 minutes of
inactivity on the ViziTouch, the “Black Screen” screen saver will activate. Its goal is to expand the lifetime of the
LCD screen. The screen saver will be instantly deactivated if the engine is running or if an alarm is activated. To
manually deactivate it, simply touch the screen or any membrane button. After deactivation, the screen saver will
always redirect to the “Home” page. It will also log off any user by resetting the security level to 0 and save any new
modifications to the settings.
