9.6.6 Doing a dosing in dosing mode "exT. rep."
The dosing mode "EXT. REP." allows for starting, via the digital inputs, the dosing of the quantity determined by a
Teach-In procedure.
danger
Danger due to electrical voltage.
▶ Shut down the electrical power source of all the conductors and isolate it before carrying out work on the
system.
▶ Observe all applicable accident protection and safety regulations for electrical equipment.
→
Connect the valves to the DO2 and DO3 outputs: see chap. 7.6.12.
→
Wire the output DO4 and the digital inputs as described in “Figure 49” and depending on the following
requirements:
• the transistor output DO4 allows for transmitting the dosing state.
• when a dosing has been interrupted, the digital input DI1 allows for the navigation within the pause menu,
between the function "CONTINUE" and the function "RESET".
• the digital input DI4 allows for interrupting or continuing a dosing, when the digital input DI1 is active. It also
allows for confirming an alarm, if the generation of alarms has been activated on the device (see chap. “9.7.16”
and “9.7.17”).

1) The LED can be replaced by another indicating system depending on the configuration of the transistor output DO4. See
chap. “9.7.18”.
2) On a version energized with a 12-36 V DC voltage, the power supply of the device can be used to energize the digital
inputs DI and the transistor output DO4; If this is the case, connect the terminal "ISOG" to the terminal (L-) of terminal block
A and use a 300 mA-fuse (instead of a 125 mA-fuse) to protect the power supply.
