9.7.12 Configuring the dosing mode "exT. rep"
The dosing mode allows for starting, via the digital inputs, the dosing of the quantity determined by a Teach-In
procedure.
Teach-In of the dosing quantity can be done either via the digital inputs or using the navigation keys.
With the Teach-In, the device automatically determines:
• the dosing quantity for each dosing made in dosing mode "EXT.REP." or "LOC. REP".
• the overfilling value to be corrected. If the overfill correction function is deactivated before the Teach-In is
started, it will be automatically activated with the "DIRECT" option at the end of the Teach-In.
• the ratio of fluid that passes through each valve, if two valves are used.
Before starting the Teach-In procedure:
• Connect the valves to the DO2 and DO3 outputs: see chap. 7.6.12.
• Parameter the operating of and the time delay before the valve connected to the DO2 output is opened:
see chap. “9.7.24”.
• If two valves are used, configure output DO3 with the function "valve" and parameter the operating of
the valve connected to the DO3 output: see chap. “9.7.25”.
• 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.
• Do not anticipate the quantity of liquid that flows after the valves have been closed. Their closing must
be controlled once the exact dosing quantity has been reached. The liquid surplus is measured and will
be corrected in the next dosings.
