Description of function
The ANZ GR 01 large-panel digital display consists of a control unit
and a display unit. The large-panel digital display with 4-digit, 7segment display (plus sign) allows both variable matching of the
signal area to a digitally precise display (e.g. 0 mA to 20 mA = 0°C
to 1800°C) and zero displacement (e.g. 0 mA to 24 mA = -100°C to
1800°C).
The display unit is intended for flush integration into the M24
Mosaik System. The height of the displayed digits is 56 mm. The
brightness of each individual 7-segment display can, to a large
extent, be adjusted to the relevant local conditions using potentiometers, accessible after removing the front panel component.
There is also a separate potentiometer for setting the brightness of
the decimal point. The decimal point can be activated via a jumper
which is also accessible after removing the front panel component.
A further jumper can be used to set the suppression of the leading
zeros. The 24 V DC supply and the LED test input are fed via a 4pin plug to the display unit.
The control unit is supplied with two cables, each with a 4-pin plug.
The control unit supply must be 24 V AC or DC. A built-in transformer ensures that the measuring circuit is isolated from the current
supply. In order to retain the isolation, a supply voltage which is
similarly isolated from the measuring circuit must be activated in the
display unit.
The display are can be adjusted in steps or using precision adjustment. The device has external inputs for a display memory which
allows the display value to be "frozen". The display unit is connected to the control unit by means of two cables with plugs.
