Tecfluid LD61 - Manual (Page 4)

ELECTRICAL CONNECTION
The LD61 can be installed as a detector of minimum or maximum level. The electrical connection
is made by means of a DIN 43650-A connector with a PG-9 cable gland. Multiple conductor cable
with sections about 0,5 mm
2
should be used.
To open the connector, remove the centre screw and prise open using a small screwdriver in the
slot shown in the following drawing (looking at the female connector from the contact side).
The working mode (maximum or minimum) is chosen by means of the cable connection, as
shown in the following figure.

NOTE: The AC version has a power consumption of 6 mA when the load is deactivated.
This should be taken into account when the load is a relay. You must make sure that the
dropout voltage of the relay is greater than the voltage across the coil when a current of 6
mA flows through it. If the dropout voltage is equal or smaller then the relay can be in an
activated position independent of the LD61 state.
