2)
LED 1) signalling the dosing state for example if the output DO4 has been
configured to transmit the state of the device.

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.

"EXT. +LOC" or "EXT. [T]"

Restart the device:
• If the DI4 input is at the low level (not powered) when energizing the device, the four digital inputs will be active
at high level.
• If the DI4 input is at the high level (not powered) when energizing the device, the four digital inputs will be
active at low level.
→
Configure the device with this dosing mode: see chap. “9.7.9”.
→
Do a dosing as shown in “Figure 42”.
• If the generation of alarms (alarm "DURING") for problems occuring during a dosing has been activated
(see chap. “9.7.16”), an alarm is generated if there is no flow rate measured in the pipe whereas the
valves are open. See chap. “10.3.4” to solve the problem.
• If the generation of alarms (alarm "AFTER") for problems occuring at the end of the dosing has been
activated (see chap. “9.7.17”), an alarm is generated if there is still flow in the pipe whereas the valves
are closed. See chap. “10.3.4” to solve the problem.
