Correct use
The base unit ESM-F-B... is used to evaluate safety-related signals in safety circuits
according to EN 60204-1. With this unit safety category 4 according to EN 954-1
can be achieved. The base unit can only be expanded using expansion devices in
the modular safety system ESM-F from EUCHNER. The device is not allowed to be
opened, tampered with, or modified. The permissible operating parameters are
to be observed during operation (see section “Technical data”).
Before the safety module is used, a risk assessment must be performed on the
machine in accordance with:
EN 954-1, Safety of machinery. Safety related parts of control systems. Gene-
ral principles for design, Annex B
EN 1050, Safety of machinery. Principles for risk assessment
IEC 62061, Safety of machinery - Functional safety of safety-related electrical,
electronic and programmable electronic control systems
Correct use includes compliance with the relevant requirements for installation
and operation, particularly
EN 60204-1, Safety of machinery. Electrical equipment of machines. General
requirements
Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or
if the safety instructions are not followed, or if any servicing is not performed as
required, liability will be excluded and the warranty void.
General safety instructions
The device is only allowed to be installed and placed in operation by authorized
personnel
who are familiar with the correct handling of safety components,
who are familiar with the applicable regulations on health and safety
and who have read and understood the operating instructions and the system
manual.
The safety function of the system while the machine is in operation can no longer
be ensured if the device is connected incorrectly or used incorrectly. Fatal injuries
may result.
Important!
Prior to use read the operating instructions and the system manual, and keep
these in a safe place. Ensure the operating instructions and the system manual
are always available during mounting, setup and servicing. EUCHNER cannot
provide any warranty in relation to the readability of the CD for the storage period
required. For this reason you should also archive a printed copy of the system
manual. If you should lose the operating instructions or the system manual, you
can download these documents from www.EUCHNER.de.

Function
The modules in the ESM-F system are used for the evaluation of the safety com-
ponents connected and the safe interruption of a safety circuit.
The base unit ESM-F-B... is part of the ESM-F system from EUCHNER. The ESM-F
system comprises at least one base unit.
The base unit has several inputs for the connection of safety components. The
safety contacts are switched as a function of the input signals. Subsequent parts
of the safety circuit can be monitored using a feedback loop.
Different device states can be signaled using monitoring outputs.
The base unit can be expanded with additional inputs and outputs using expansion
modules. The individual modules are connected together using a special connector
system. Power is supplied and safety signals are sent via the connector system.
If one of the safety components (e.g. an emergency stop) is actuated, the base
unit opens its contacts immediately. If additional output modules are used, these
also receive a signal to open their contacts. The system is designed such that
failures will not result in the loss of the safety function. The occurrence of failures
is detected by cyclic self-monitoring at the latest on the next demand to close
the safety contacts (e.g. on starting). The system can be started either manually
using a start button or automatically using a jumper. Safety groups with varying
safety levels can be formed using appropriate configurations (see section Forming
safety groups).

Status LEDs and pin assignment
All modules in the ESM-F system have status LEDs for the important module sta-
tes. The significance of the individual LED states is given in the section Trouble
shooting.
