11.3CONTROL AND HMI
Q1.
What is the difference between Get/Send info from/to relay and Upload/Download info files to/from relay?
A1.
Get/Send are used for settings and configuration storage that although both are in a unique file, are sent separately
in two times. Upload/Download are used for project or PLC files group storage. These files are the
setting_configuration file source. To operate, the G650 does not need the source files; the Upload/Download tool is
destined to serve as historic file.
Q2.
Could I program interlocks?
A2.
Yes, via ENERVISTA 650 Setup interlocks may be programmed from very simple to advanced schemes.
Q3.
Can we rotate the display 90 degrees to show feeders vertically?
A3.
No. The product has been designed to view it in horizontal mode (landscape) due to the following reasons:
It is easier to read the LCD display because it has been designed for horizontal positions.
Compatibility between text display (4x20 characters) and LCD display (16x40 characters or 128x240 pixels).
Refresh speed is better in horizontal than vertical format.
Q4.
Do I need a laptop or handheld to program the unit?
A4.
No, all main operations can easily be performed with just the incorporated HMI. Handheld or laptops may be
required to download large quantities of information (such as oscillograms, etc.) but they are not mandatory for a
conventional user that just needs to change settings, view measurements, states, etc.
Q5.
Is there password security for protection and control?
A5.
Yes, there are two passwords. An independent password for protection changes and control operations is available
Q6.
Is it possible to have a remote HMI installed in the front of the panel with the rest of the relay in the rear
side?
A6.
Not in the present version.
Q7.
Is it possible to program a default screen for the HMI?
A7.
In graphic display versions the user may program a custom screen with the single-line diagram, measurements, etc.
In text display models, there is a choice of logo, measurements, or scrolling both screens.
Q8.
May I force inputs and outputs to ease commissioning and testing?
A8.
Yes.
Q9.
How can I disable the rotary knob buzzer?
A9.
Press ESC key more than 3 seconds and then press the knob during a short pulse.
Q10. Why do appear strange texts on the display when switching on the relay?
A10. You will have pressed any button and the HMI has entered in a test mode.
The display messages are updated after a few minutes, once the relay has completed the starting sequence.
