CAUTION
Please observe the following to ensure that the
DL..K is not damaged during operation:
– If the DL..G (DL..TG) has switched a volt-
age > 24 V (> 30 V) and a current > 0.1 A at
cos φ = 1 or > 0.05 A at cos φ = 0.6 once,
the gold plating on the contacts will have been
burnt through. It can then only be operated at
this power rating or higher power rating.
– Note the switching capacity, see page 4
▷
In the case of high humidity, we recommend
using a pressure switch with gold contact due to
its higher resistance to corrosion. Closed-circuit
current monitoring is recommended under dif-
ficult operating conditions.
▷
In the case of low switching capacities, such as
24 V, 8 mA, for example, we recommend using
an RC module (22 Ω, 1 μF) in air containing
silicone or oil.

Disconnect the system from the electrical power
supply.

Adjustment
▷
The switching pressure can be adjusted using the
hand wheel and scale. The switching pressure
differs from the adjusted setpoint by a maximum
of ± 15%, when it has been set for increasing
pressure and with a vertical diaphragm.
