E-Stop Safety Module
– Model ES-FA-6G
page 4
This E-stop Safety Module complies with the following design standards:
UL991 Tests for Safety Related Control Employing Solid-state Devices
EN418 Emergency Stop Equipment - Functional Aspects, Principals for Design
EN954-1 Safety of Machines: Safety-related Parts of Controllers
Part 1: General Design Directives (Safety Category 2)
The Safety Module has indicators for input power and output relay contact status (K1
and K2); see Figure 1. There are no adjustments and no user-serviceable parts. See
page 9 for information regarding repair service.
E-Stop Switch Requirements
As shown in Figure 3 or 4, the E-stop switch must provide one contact which is closed
when the switch is in the “armed” position. Once activated, the E-stop switch must
open this contact. The switch may be returned to the closed-contact position only by a
deliberate action (such as twisting, pulling, or unlocking). Additionally, NFPA79 section
13.2, Emergency Stop Devices, specifies the following switch (“stop control”)
requirements:
• Emergency Stop push buttons shall be located at each operator control station
and at other operating stations where emergency shutdown shall be required.
• Stop and Emergency Stop push buttons shall be continuously operable from
all control and operating stations where located.
• Actuators of Emergency Stop devices shall be colored RED. The background
immediately around the device actuator shall be colored YELLOW. The
actuator of a push-button-operated device shall be of the palm or mushroom-
head type.
• The Emergency Stop actuator shall be a self-latching type.
NOTE: Some applications may have additional requirements. The user must refer to all
relevant regulations.
Mechanical Installation
The E-stop Safety Module must be installed inside an enclosure. It is not designed for
exposed wiring. It is the user’s responsibility to house the Safety Module in an
enclosure with NEMA 3 (IEC IP54) rating, or better.
Dimensions of the Safety Module are shown in the diagram on page 11. The Safety
Module mounts directly to standard 35 mm DIN rail.
CAUTION. . .
Shock Hazard
Always disconnect power
from the E-stop Safety
Module and all power from the machine
being controlled before making any wire
connections.
Electrical installation and wiring
must be made by qualified personnel
and must comply with the NEC
(National Electrical Code), EN60204-
1 and -2, and all applicable local
standards and codes.
