only for signalling functions and

not for safety functions .

OPERATING MODE

With manual START configura-

tion, the safety outputs close, if

S1 & S2 are operated, when the

NO START pushbutton is pushed .

With automatic START configu-

ration, the safety outputs close

(NES13DB opens the auxiliary

output) as soon as both S1 & S2

switches are operated . The CH1 &

CHl 2 LED turn on .
Releasing even one input contact

(S1 and/or S2) forces immediately

the safety outputs to an open sta-

tus (NES13DB closes the auxiliary

output) . 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 without 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

devices connected to the inputs

and to the outputs of the module .

Check also the correct 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

LEDs are off,

the safety outputs open and the

auxiliary output is closed .
Operate the input contacts: the

safety outputs are open and the

CH1

CH2

LEDs are off (if the

module is configured for automatic

START,

CH1

CH2

LEDs turns

on, the safety outputs close) .
Close the START contact: the
