is drawn the greater the effect over distance. Voltage drop will be greater with direct current
versions.
The float switch supplied is a 2 way float switch, it is set by default to close the circuit when the
float is facing downwards. This suits the majority of tank re-filling applications. If desired it can be
re-wired to close when the float is held upwards to suit tank drainage requirements. To do this the
wiring within the plug attached to the float switch must be changed. The brown wire is common
and connected to the voltage to be switched, blue returns voltage when the float is facing up and
black returns voltage when the float faces downwards. Cables extension is straightforward using
mains flex, there is no neutral, and there is no earth, only one pole is carried through the float
switch. For the extension of float switch cables we recommend an IP68 cable joiner 3P Part
number X20BKSD.
Suitable circuit protection must be installed and should include as a minimum a suitable earth,
overcurrent protection, and residual current protection at 30mA, ideally on it's own circuit, but
always in accordance with BS7671 and applicable regulations.
Control Panel Mounting
Open the cover of the control panel. There are 4 recesses, one on each corner of the panel. Drill
through at these locations and attach to the wall or a suitable support, taking care not to damage
cabling inside the panel. Fixings are not included and should be selected to suit the material to
which the panel will be mounted.
Connections
Float Switch
The 2 outer poles in the plug should be used. Polarity is unimportant for the float switch
connection. If you are using a double switching float switch (3 wires), select the 2 wires which
connect when the float switch is hanging downwards.
The float switch cable should be fastened within the tank between the points at which you want
the top-up cycle to start and stop. The distance between start and stop is determined by the length
of free cable to the float.
Solenoid
The polarity of the solenoid connection is unimportant if you have the AC version of this unit
(TCS5JBLA). If using the DC version, the pole marked L in the plug will be positive, and the pole
marked N will be negative, although it is good practice to verify this with a multimeter during
