7.3 Electrical connection
The operating voltage and frequency are marked on the controller
nameplate. Make sure that the controller is suitable for the
electricity supply on which it will be used.
All cables/wires must be fitted through the cable entries and
gaskets (IP65).
The power supply socket must be placed near the cabinet as the
controller is supplied with a 1.5 m cable, a Schuko plug for
single-phase and a CEE plug for three-phase pumps.
Maximum backup fuse is stated on the controller nameplate.
If required according to local regulations, install an external mains
switch.
7.4 Setting of LC 220
LC 220 has a 4-contact DIP switch. See fig. 16 .
To make the settings, open the cabinet cover by means of the
bayonet fastener locks. The locks on the left side have hinge
strings.
The DIP switch has the following functions:
• setting of start level (switch 1). The factory setting is set to
inlet 250 mm above the floor to get the highest effective tank
volume. For floor standing toilets, the setting must be changed
to 180 mm. Starts and stops will be adjusted automatically.
• selection of automatic alarm resetting (switch 2)
• selection of service interval (switch 3)
• selection of sensor (switch 4).
The DIP-switch factory setting is shown in fig.
16 .
Each individual switch (1 to 4) of the DIP switch can be set to
position OFF or ON.
When the DIP-switch setting is changed, the controller must be
switched off for at least 10 seconds!
Set the switches 1 to 4 as follows:
•
Switch 1 (start level):
• Switch 2 (automatic alarm reset):
• Switch 3 (service interval):
• Switch 4: (sensor resetting):
