Operating buttons EZ has eight operating buttons. These are used to select
menu functions and create circuit diagrams. The large round
button in the middle is used to move the cursor.
DEL, ALT, ESC and OK all perform additional functions.
Output You can connect various loads to the four EZ outputs, such as
contactors, lamps and motors. In the EZ circuit diagram the
outputs are controlled via the corresponding output relay coils
Q1 to Q8 or S1 to S8.
P buttons The P buttons can be used to simulate four additional inputs
which are controlled directly by the four cursor buttons, rather
than via external contacts. The switch contacts of P buttons
are connected up in the circuit diagram.
Parameters Parameters enable the user to set the behavior of a function
relay. Possible values include switching times or counter
setpoints. They are set in the parameter display.
Power supply EZ-AB is supplied with an 24 V AC supply. The terminals are
labelled “L” and “N”.
EZ-AC is powered by AC voltage at 85 to 264 V AC, 50/60 Hz.
The terminals are labelled “L” and “N”.
EZ-DA is supplied with a 12 V DC supply. The terminals are
labelled +12 V and 0 V.
EZ-DC is powered by DC voltage at 24 V DC. The terminals
are labelled “+24 V” and “0 V”.
The terminals for the power feed are the first three terminals
on the input side.
