E-Stop Safety Modules with Fixed Delay –
In addition to the safety contacts, the E-Stop Safety Module has one normally closed
immediate auxiliary contact (from K1 and K2) and one normally closed delayed auxiliary
contact (from K3 and K4) for status monitoring by a process controller.
All output contacts of the E-Stop Safety Module, the normally open and the normally
closed, are rated for up to 250V ac/dc at up to 4 amps.
The E-Stop Safety Module also provides a necessary reset function. ANSI B11 and
NFPA 79 standards require that a Reset routine be performed after returning the
E-stop switch to its closed-contact position. This prevents the controlled machinery
from restarting simply by closing the E-stop switch. Models ES-TN-1H.. may be
configured for Automatic Reset via two DIP switches located inside the Module
housing, under the front cover (see Figures 5 and 6). Automatic Reset mode is
useful for some automated processes. However, when Automatic Reset is used,
an alternate means must be established to require a Reset routine after the E-stop
switch is returned to its closed-contact position (see WARNING on page 9).
This E-Stop Safety Module complies with the following design standards:
EN418 Emergency Stop Equipment - Functional Aspects,
Principles for Design
ISO13849-1 Safety of Machinery: Safety-Related Parts of Control Systems
(EN954-1) Part 1: General Design Directives (Safety Category 4)
ISO/TR 12100-2 Safety of Machinery: Basic Concepts, General Principles for Design
EN292-2–1991 Part 2: Technical Principles and Specifications
IEC 60204-1–1997 Safety of Machinery: Electrical Equipment of Machines
Part 1: General Requirements
The Safety Module has indicators for input power (Power), internal faults (Fault),
E-stop inputs (E-Stop), reset input (Reset), monitoring of feedback contacts (Monitor),
immediate outputs (Out) and delayed outputs (Timed-Out); see Figure 1.
E-Stop Safety Modules ES-TN-1H.. have no user-serviceable parts. See page 16 for
information regarding repair service.
