The maximumdosing capacity must not be exceeded.Input range for the dosing capacity per contactEven if the pump receives more contact signals thanit can process at the maximum flow rate, it only runsin continuous operation with a maximum strokefrequency of 180/min. (120/min. in slow mode).Contact ml1.75Fig. 40 Display: contact signal controlUse the "Up" and "Down" buttons in the first functionlevel to set the dosing volume for each contactsignal.1. When the pump is stopped (LED lights up red),press the "Menu/Info" button.– The first function level is opened.2. Use the "Up" and "Down" buttons in the "contactsignal control" menu to set the dosing volume percontact signal.3. Press the "Start/Stop" button to confirm thesettings and to exit the first function level.– The pump is running (LED lights up green).9.4.4 Current signal control 0-20 mA / 4-20 mAFor current signal control, see section 9.9 Currentsignal control 0-20 mA / 4-20 mA.TM03 6602 4506Pump typeStroke volumeMin. dosing capacity(= 1/50 stroke/contact)Max. dosing capacity(= 4 strokes/contact)[ml] [ml] [ml]DDI 0.4-10 0.07 0.001 0.28DDI 2.2-16 0.22 0.004 0.86DDI 2.5-10 0.22 0.004 0.88DDI 5.5-10 0.55 0.011 2.20DDI 13.8-4 1.24 0.025 4.96DDI 20-3 1.92 0.039 7.8637
