le is correctly powered, the input

switches are operated, and the

START circuit has been activated,

as described in this user manual .

OPERATING MODE

With manual START configura-

tion, the safety outputs close, if

the switches connected to S12

& S21 are operated, when the

NO START pushbutton is pushed .

With automatic START configura-

tion, the safety outputs close as

soon as both the switches con-

nected to S12 & S21 are operated .

The Channel 1 & Channel 2 LED

turn on .
Releasing even one input contact

(S12 and/or S21) forces imme-

diately the safety outputs to an

open status . The LED relative to

the channel whose input has been

released turns off .
A new operating cycle is possi-

ble only after releasing both input

contacts and then operating them

again (and pushing the START

button, if the safety module has

been set up with manual START

configuration) .
For the “SC” and “DC” models it

is necessary a minimum delay of

500 ms from the operated status

of the input contacts to the pushing

of the START button . The same

delay is necessary between the

START button releasing and re-

operating, if the input terminals

have been previously operated

with the START button already

pushed .
In the models with monitored

manual START configuration, if

the NO START button gets wel-

ded, the safety outputs cannot

close their contacts any more .

TEST & ACTIVATION

The following operations must

be repeated when the module is

installed and every time the wiring

is changed and at regular intervals

by carrying out in sequence all the

steps described below avoiding

any type of dangerous condition

for the operators .

STEP 1

Check the integrity, the

correct installation, the correct

positioning on the machine and the

correct functioning of all the devi-

ces connected to the inputs and

to the outputs of the

NLG02D724..

safety module . Check also the cor-

rect wiring of all the devices .

STEP 2

Power on the safety

module: the

POWER

LED turns on

(this LED has to be considered ON

in all the steps of this sequence) .

The

CH1

and

CH2

are off .

Operate the input contacts: the

safety outputs are open and the

CH1

CH2

are off (if the module is

configured for automatic START,

CH1

CH2

turns on and the safe-

ty outputs close) .
