7.7 Analogue Output (only ZOK-Z3 with Supply option ‘3/6/0’)
7.7.1 2-Wire Configuration 4-20 mA
The options ZOK-Z3/-E3 can be operated as a source in a 2-wire 4-20 mA current
loop. However, only passive Reed switch (option -R0) should be used as a sensor. In
2-wire loop operation, no other active outputs are available. If the electronics is
connected in 2-wire configuration, the display will show „LOOP“ at the top. The wiring
type must be set to "2-WIRE" in the Analogue Output menu.
7.7.2 3-Wire Configuration as active output, current source
In the 3-Wire Configuration, the load is connected between current output (-) and GND
and all types of sensors can be connected and all other outputs can be used. If the
electronics is connected in 3-wires, the display will show „EXT“ at top left (external
power supply). The wiring type must be set to "3-WIRE" in the Analogue Output menu.
All sensor types can be connected at the signal input.
