ATTENTION :
READ CAREFULLY ALL THE PRESENT MANUAL AND THE
INSTRUCTIONS REPORTED ON THE LAST PAGE BEFORE THE
INSTALLATION.
TECHNICAL CHARACTERISTICS
Power Supply:
12/24V ac/dc
Absorption 24V ac/dc:
44 mA
Absorption 12V ac/dc:
27 mA
Range relays:
1A to 24 VAC

Exit supply TX photocell:
12 o r24 V ac/dc it depends from the voltage of the supply of the decoder
SA04PLUS : it will be the same voltage of the supply
Entry central with test:
Accept tension from 10V to 30V ac/dc : Usually the central gives voltage
of supply typical of the photocell

J U M P E R
J1
Insert if the power supply is of 12 V ac/dc
Do not insert if the power supply is of 24 V ac/dc
J2
Insert if the central of command is not dued of TEST
J3
Insert if in one or more entries are present safety elements such as NO TOUCH and if you
want to do the periodical test
REMEMBER ABOUT J3 : THE PERIODICAL
TEST IS ACTIVABLE ONLY IF THE CENTRAL
OF THE MOTOR DOESN'T HAVE THE
PHOTOCELL TEST INSIDE. THE PERIODICAL
TEST EFFECTS THE TEST OF THE RELAYS
OF THE NO TOUCH EACH 10 SEC.
