Retrofitting relays (not by PROFIBUS
®
version)
Delivery range:
1
relay circuit set with 2 screw fasteners
1
relay cable set with socket
1
seal
Press-out relay opening
WARNING
Disconnect the S1Ca from the mains power supply and rinse liquid end before
commencing work (see section 10)!
NOTICE
When preparing the opening, ensure that the punch is not forced through the
entire pump base!
Pump circuits may become damaged.
왘
Place the S1Ca on a firm surface with the relay opening press-out section at the top (see
fig. 17)
왘
Place a punch (dia. 8-15 mm) in the centre of the relay opening press-out section , and
strike briefly and sharply with a hammer (approx. 250 g)
왘
If necessary clean up the edges of the opening
왘
Remove the pressed out section from the S1Ca
Inserting the relay component
왘
Hold the relay component with your right hand gripping the left and right hand edges of
the relay cover, and tilt the front end slightly to the left (see fig. 18)
왘
Push the relay component through the relay opening, holding the upper corner of the lower
edge against the guide rail on the pump base, until the contact of the relay component has
reached the controller contact. (test: can you still move the end of the circuit back and
forth?)
왘
Gently push the relay component right into the opening
왘
Screw the relay cover firmly onto the housing using the screws provided
왘
Insert the relay cable plug seal into the relay cover and screw on the plug (see fig. 20)
왘
The pump is generally programmed ex-factory to „drop-out action alarm relay“ and – if
fitted – „pull-up action clock pulse generator relay“. If a switching function is required, the
pump can be reprogrammed at the Heidelberg plant (not necessary by PROFIBUS
®
-version).

NOTICE
•
The universal signal cable, the external/contact cable and the level monitor
cable should not be less than 1.20 m long, otherwise cable recognition will fail.
