Electrical connections
!
Carefully follow all the connection instructions. If you have any doubts do not make experiments but consult the relevant
technical specifications sheets which are also available on the web site www.king-gates.com.
An incorrect connection may cause serious damage to the control unit. Do not connect multiple motors in parallel unless
specifically required by the type of motor; if necessary, use the appropriate expansion cards.

Notes regarding connections
The control unit features two low voltage (24Vdc) supply terminals (10-
11) for the services (photocell). Three additional terminals (12-13-14)
are designated for the command and/or safety inputs; as for the latter,
the 0 volt terminal (10) is the common one. Some of these inputs have
functions that depend on the programmed settings.
STOP input
This input is designated for the connection of safety devices such as
sensitive edges. The input can be used with normally closed (NC) as
well as normally open (NO) contacts or constant resistance contacts
(8.2kΩ). To set dip-switches 3-4 based on the type of input used,
refer to the "Programmable Functions" chapter.

Description
230V flashing light
motor control output (close, common, open, earth)
mains power supply line (earth, phase, neutral)
24Vdc output (services) max 50mA
safety device input (Stop/sensitive edge)
photocell input
input for cyclic command (open-stop-close-stop)
radio receiver aerial input
Warning: the minimum resistance level required by law can only be
guaranteed by the constant resistance input (dip-switch N°3=ON).
Normally the activation of the device connected to the Stop input
causes the stop of the movement with a short inversion. To deac-
tivate this inversion caused by the activation of the safety device,
when the sensitive edge touches the ground for example, a contact
"S" can be used in series with a 8.2kΩ resistance connected in par-
allel with the sensitive edge (see figure 3).
Contact "S" is positioned such that the last 30-40 cm of the closing
movement close before the sensitive edge activates.
When contact "S" is closed and the sensitive edge is activated by
the floor, the automation blocks without inversion keeping the door
completely closed.
