ENGLISH
Electric noise
Signal cables for sensors, DI inputs, data communication
and display must be kept separate from high voltage
(230 V) electric cables:
- Use separate cable trays
- Keep a distance between high voltage and signal cables
of at least 10 cm
Cables for DI input.
Cables longer than 10 meter (33 ft) is not recommended.
At cables longer than 10 meter (33 ft), it is recommended
to use auxiliary relays, placed within 10 meter (33 ft) cable
distance. Typical auxiliary relays then are placed in the
same panel, as EKE 400.
Warning
The supply voltage of AI may not
share the signal with other controllers.
Valve congu-
ration no.

Supply Voltage.
Supply voltage depending on model:
85 – 265 V AC, 50/60 Hz. Maximum power consumption: 20 V A
20 – 60 V DC and 24 V AC ± 15% 50/60 Hz , Maximum power
consumption: 10 W, 17 V A.
Modbus
It is important that the installation of the data communication
cable be done correctly. Cf. separate literature No. RC8AC.
Remember termination at the bus termination.

OBSERVE:
Connect 24 V on N and L (separate supply). Avoid earth fault
current. Use double-insulated transformer. The secondary side
must not be earthed.
Obtain 0 – 10 volts from terminals N and AO3, respectively
N and AO4.
PAY ATTENTION TO THE POLARITY of N.
