6.6 Continuous pulse output

Each of the outputs 1 to 4 (terminals DA1 to DA4) can emit continuous pulses for testing purposes.

6.6.1 Parameterization

Parameterization is carried out via the keyboard on the EK280.
Alternatively, parametrization can be carried out using the enSuite program. The paths which are subsequently
described can be found in enSuite under
Setting up the output mode:

Move the cursor to the tab "Serv." and subsequently via the following path to the mode for the
corresponding output "Md.O1" to "Md.O4":

Press the ENTER  button. The set value flashes.

 Press one of the arrow keys  or  until the "cont.pulse" text flashes.

Press the ENTER button to confirm the set value. It is possible to abort the entry by pressing the
ESC button.

6.7 Switching pulse inputs on or off

Each of the outputs 1 to 4 (terminals DA1 to DA4) can be permanently switched off (transistor closed, "switch
open") or switched on (transistor conducts, "switch closed").

Press the ENTER  button. The actual parameterized value flashes.

 Press down one of the arrow keys  or  press repeatedly until the text "off" or "on" flashes.

Press the ENTER button to confirm the set value. It is possible to abort the entry by pressing the
ESC button.

6.8 Connecting outputs to a PLC or an isolation amplifier

i
When connecting the outputs to a customer system (e.g. PLC) galvanic separation of both
systems is strongly recommended. Especially when using or connecting the EK280 to a
hazardous area (hazardous area 1), an external isolation amplifier (permitted for use in
hazardous areas) or usage of the FE260 is required.
i
A galvanic separation is also recommended outside the hazardous area to exclude
disturbances of the systems with each other. This can be carried out separately for each output
via the internal slide switch. Alternatively, an external cut-off relay.
