EZ HMI Display Terminal
1. DISPLAYING MESSAGE
The LCD used in the EZ HMI has a display area

messages and other info.

Tip:
The LCD display does not respond well with
8=0;"<:=2L.2L"K.073=4T"]</133.2L"9+00=L+"9=4"/+0-3;"
in display that appears to overlap on top of each
other, hence, may be hard to read. To minimize this,
adjust the LCD contrast until an acceptable scrolling
display is obtained. This may result in lower over-

2. PARAMETERS AND PARAMETER ENTRY
MODE
The EZ HMI Parameter Entry Mode is a built-in func-
tion that allows you to set, modify, and save to EZ
HMI non-volatile memory up to 48 data sets; we will
refer to these data sets as parameters here on. This
function will be useful for applications where param-
eters need to be adjusted by the user from time to
time. Example applications includes (and not lim-
ited to) temperature control, process control, timer,
instrumentation - to name just a few.
Using the same function, each parameter can be

2.1 Entering Parameter Entry Mode
Parameter entry mode can be initiated by program
control (see section 4.7) or by pressing the encoder
switch push switch as follows:
