2 Safety instructions These operating instructions include important information which must be observed when setting-up, commissoning and operating the plant. These operating instructions must be kept readily available at the place where the plant is employed. The control may only be connected and maintained by a suitably qualified specialist.
3 Connections Mains connection The plant is connected to the mains by means of the supplied power cable (approx. 1,5 m long) with Shock-proof plug (clips L1, N, PE). Fuse protection on line side: max. 1 x 16 A G. 7 - pole plug The following inputs and outputs are routed through a 7 - pole plug on the underside of the device.
3 Connections If you want the warning light / flashing light to illuminate / flash in the event of an error, it should be connected via contacts 11 and 12 (see diagram). For continuous illumination, the connection between 11 and 14 should be chosen. 4 Function Operation and displays The control has a graphic LCD - display mit 128 x 64 pixels.
4 Function Commissioning When commissioning the unit, the following information must be entered first: - Password - Language (see menu item 5.4.4) - Date and time (see menu item 5.4.1) - Plant size (see menu item 5.3.3) - Denitrification (see menu item 5.5.2) - PO -elimination (only for type K-Pilot 8.4, see menu item 5.3.4) - Test mode - lasts approx.
5 Menu The exact display is dependent on the plant´s status and the set parameters. The different display versions are described in more detail below. Runtime display The menu item “runtime” displays the runtimes of the respective motors. The runtimes are counted when the control has turned on the aerator or the pumps.
5 Menu System test process 1. Aerator 10 s 2. Filling pump 10 s 3. Clear water pump 10 s 4. If the float switch is down, wait until float switch changes position 5. Aerator until float switch changes ist position once again 6.
5 Menu Basic settings The operator settings are configured in this menu. 5.4.1 Setting the date and time Example: Changing the date from 04.03.00 to 14.03.00 and the time from 07:53 to 07:54 o´clock.
