CONTROL UNITS UTR230868 / UTR40086888
ELECTRICAL CONNECTIONS
CONNECTOR CONTACT DESCRIPTION
20
S
The input of the control devices ‘Stop’ (g.14, STOP) with a normally closed
contact (NC). Actuation will immediately stop the door movement or block the
start of the door movement
+24V Power output of additional devices. Supply voltage 24V DC (DC) / max.250 mA
+12V Power output of additional devices. Supply voltage 12V DC (DC) / max.150 mA
SE
Security resistive edge connection input 8.2kOhm (g.14, 8K2) or optical
safety edge connection (g.15, OSE). In the settings (tab.13, P7–F4), the type
of edge (sensor) is set. Contact of the door leaf with an obstacle when closing
(actuation of the installed sensor) will stop the door movement and then open
it (tab.13, P5–F5)
PH1
Security device input (photocells, g.16) with normally closed contact (NC).
Actuation when closing will stop the door movement and then open it (tab.13,
P5–F5), or block the start of closing
PHT
An output for automatic verication the operation of photocells (PHOTOTEST)
connected to the input PH1. In the settings (tab.13, P7–F3), the PHOTOTEST
is enabled. Before starting the movement, briey turning o, then turning on
the power of photocells, an automatic verication of the photocell operation is
performed.
An example of a scheme for connecting photocells with a power o of
the photocell transmitter is shown in g.16. An example of a scheme for
connecting photocells with a transmitter powered by batteries is shown in
g.17
7–9
J1.1– J1.3
Normally open (NO) relay
contact
Potential-free relay outputs (dry contact).
Maximum load: no more than 3A.
The relay operating mode is set in the settings
(tab.13, P3–F4…F6). The relay operating modes
are described in tab.14
J2.1– J2.3 General relay contact
J3.1– J3.3
Normally closed (NC) relay
contact
11
L (L1)
Outputs 230V / 50Hz for powering additional devices. Maximum load no more
than 3A
N
15
GND Input connection of shielding antenna conductor
ANT
GND
15
RG58
ANT Input connection of signal antenna conductor
17 LOCK
Switch connector with key (option). The switch is installed on the unit body.
Using the key, the switch is transferred to the (NC) position, which blocks the
commands of the control devices (unit buttons, control switches, radio remote
controls, etc.), or to the (NO) position, in which control is enabled.
LOCK

NC
Control is blocked
LOCK

NO
Control is enabled
