10 Relay contacts (optional)
Purpose of the relay contacts:
The relay contacts of the optional relay module can be used to report the following gate states to the higher-level controller:
● X11 (Pin1 and Pin3 closed) → The cold room gate has reached the "CLOSED" position
● X12 (Pin1 and Pin3 closed) → The cold room gate reverses because of a blockage, interruption of the light barrier or an
opening command.
● X13 (Pin1 and Pin3 closed) → The cold room gate has reached the "OPEN" position
Safety information to observe when connecting the relay contacts
WARNING
Danger of injury during transport of people or goods
The ATD400K controller is not a safety mechanism! The safe transport of people or goods can no longer be ensured in the
event of misappropriation of the relay contacts.
Do not use the relay contacts for the safety circuit of the cold room gate.
DANGER
Risk of injury from dangerous electrical voltages.
When the housing cover is opened, only a safety extra-low voltage of less than 42V may be present. The protective cover
provided must be used when a higher voltage (max. 230 VAC) is connected to the relay module. Observe the following
guidelines:
● The cables connected must be suitable for the voltage used and have appropriate (double or reinforced) insulation.
Cables with an external diameter of 6 to 7mm are recommended.
● Inside the cover, the single-insulation must be removed from the single cores at least 5mm from the cable entry
openings, and the cores connected as short as possible to the terminal connectors. The cables must be secured inside
the plastic cover against being pulled out. A cable tie, which has been pulled tightly around the cable, prevents the
cable from being pulled through the oval opening in the relay cover. The cable tie must be applied in such a way that a
minimum of 5mm of the outer cable jacket lies inside the protective cover. Components of the controller and connecting
cable, such as the motor plug and its wires, may only come in contact with the additional (or reinforced) insulation of the
current-carrying wires.
● Networks with different voltages (e.g. 24V and 230V) must not be connected to the relay module. Additional strain relief
is provided by cable ties at the fixing points provided in the housing.
