Description
• Both 9-volt batteries must be connected to the circuit board
• The power supply must offer a full pole main switch that is directly connected to
the controls
• The required fusing on-site must not exceed 16 Amps
• The power chord for the entire system is a 1.7 meter long cable
• The motor cables are to be connected to the proper connection jacks marked
'motor' inside the control unit. (Please follow the correct order).
Motor PE
Motor U1 / Z1
Motor U2
Motor Z2
Temperature switch T1 = jack 4;
Temperature switch T2 = jack 5
• The ground cable should be connected to the PE jack on the 'motor' connec-
tion jack
Level signal (ON / ALARM) for units up to and including December 2009
• The level sensor cables are to be connected to the proper connection jacks.
(white cable right, brown cable left on connection 'Ein', green cable right and yel-
low cable left on connection 'Alarm').
• The level sensor connection jacks cannot be connected to any other circuit or
power source
• The jacks are marked with a switch symbol
Connection of level sensors built after and including January 2010.
• The transparent hose must be laid with a continuous positive slope from the
pump to the control unit. No kinks or loops / coils are allowed in this hose. The
connection of the level sensor cable must be connected and screwed firmly to
the proper connection on the control unit.
• the potential free contact is capable of handling 42 V AC / 0.5 Amp. The poten-
tial free contact must be supplied with external power within the previous stated
range.
• The potential free contact allows malfunctions such as a power outage, war-
nings, malfunctions to be transfered via relay to a secondary alarm or BMS sour-
ce
• Inductive loads must be protected from the potential free contact.
• The relay contacts have no internal connection to any supply or operational vol-
tage and are completely separate up to a voltage of 300 V according to Table
D.10 from Norm EN 61010 (Power surge category 2 u. Contamination level 2).
