ATTENTION!
Prior to commencing the wiring operation, make sure that the wire is not ‘
live
’.
When using and installing additional electric devices (accessories) follow the manuals supplied.
Incorrect connection can result in the failure of the drive.
Use only additional devices (accessories), offered by ALUTECH (including AN-Motors). ALUTECH
does not bear responsibility for unstable operation of the drive system, if additional devices,
produced by other manufacturers, are used.
If no devices are connected to terminals ‘
PH1
’ and ‘
S
’, crossovers should be installed. If a safety
device is connected to the terminals mentioned, remove the crossover.
Open the lid on the drive to access the additional device connectors, configuration and indication
elements. Press the latch and turn the lid (
fig.
22).
Table 4
describes the contacts of the drive connectors used to connect additional devices. The
connection diagram and symbols are presented in
fig.
23.
Figures 24–28 show examples of connecting additional devices (accessories), manufactured
by ALUTECH:
• figure 24—connection of a signal lamp with built-in antenna.
• figure 25 —photocells connection.
• figure 26—connection of photocells with
PHOTOTEST
function.
• figure 27—connection of optical safety margin.
• figure 28—connection of resistive safety margin.

Optical sensors connection input or input of resistive margin of safety (8.2 kOhm).
In settings (section ‘6. Adjustment’
P7
–

) the following can be selected, depending on
the connected safety device: resistive sensor (
fig.
28) or optoelectronic sensor (
fig.
27).
The contact of the door with an obstacle during closing (activation of a sensor) causes
the door to stop moving and then fully open
