fuse in series to the safety out-

puts to reduce the risk of the

safety outputs contacts welding

(see outputs technical data). 

- Never, in any situation,connect

spark quenching unit circuits in

parallel to safety outputs con-

tacts: the safety function would

no longer be guaranteed.

- Never, in any circumstance,

exceed the electrical ratings sta-

ted in the technical data table of

this manual.

INSPECTIONS AND

MAINTENANCE

The integrity of the module and of

all the connected devices must be

checked regularly according to the

risk evaluation of the plant, under

the complete responsibility of the

user. Regular inspections must be

performed repeating all the opera-

tions listed in the TEST & ACTIVA-

TION section.

In particular it is necessary to per-

form regular tests on board in

order to verify that the input devi-

ces are not faulted. 

In the event of a switch-off of the

module or of the machine it is

necessary to repeat all the opera-

tions listed in the TEST & ACTIVA-

TION section in order to verify the

integrity of the external

device system.

The safety module doesn’t require

internal maintenance: it must be

periodically cleaned - with plant

and module powered off - together

with all the connected devices,

removing dust, liquids and conden-

sation.

APPLICATIONS

In Fig. 3 and 4 are shown the con-

nections of ESPE with 2 one-wire

outputs: the ESPE outputs are

connected to S11 and S22.

The negative supply terminal (A2)

of the module is connected to the

GND terminal of the power supply

source together with the negative

supply terminal of the ESPE.

The N.C. contacts of the external

contactors are monitored by the

START circuit: if one contact gets

broken, the safety outputs of the

module can not close any more

during the next START cycle.

The category of the application can

reach up to category 4 according

to the EN954-1 and EN13849-1

standards.

In Fig. 5 and 6 are shown the con-

nections of ESPE with 1 one-wire

output: the ESPE output is connec-

ted to S11 and S22 is short-circui-

ted to S11. The category of the

application can reach up to catego-

ry 2 according to the EN954-1 and

EN13849-1 standards.

In Fig. 7 and 8 are shown the con-

nections of ESPE with 2 two-wires
