ES-UA-5A and ES-VA-5A E-Stop Safety Modules
Some applications may have additional requirements; comply with all relevant regulations. See the device man-
ufacturer installation instructions for complete information (such as SSA-EB..-.. p/n 111880, or RP-RM83F.. p/n
141245 installation data sheets).
Interlocked Guards (Gates)
The safety inputs can be interfaced with positive-opening safety switches to monitor the position of an interlock
guard or gate. Each switch must provide electrically isolated contacts: at minimum, one normally closed (N.C.)
contact from each individually mounted switch. The contacts must be of "positive-opening" (direct-opening) design,
as described by IEC 60947- 5-1, with one or more normally closed contacts rated for safety. In addition, the
switches must be mounted in a "positive mode," to move/disengage the actuator from its home position and open
the normally closed contact when the guard opens.
In higher levels of safety performance, the design of a dual-channel coded magnetic switch typically uses comple-
mentary switching, in which one channel is open and one channel is closed at all times. The inputs of the Safety
Module do not support complementary switching, and thus should not be used with coded magnetic safety
switches.
The design and installation of the interlocked guard and the safety switches should comply with ANSI B11.19,
ISO14119, and other applicable standards. See the device manufacturer installation instructions for complete infor-
mation (such as SI-LS83/-LS100 p/n 59622, or SI-HG63 p/n 129465 installation data sheets).
The Safety Module must be installed inside an enclosure. It is not designed for exposed wiring. It is the user's re-
sponsibility to house the Safety Module in an enclosure with NEMA 3 (IEC IP54) rating, or better.
The Safety Module mounts directly to standard 35 mm DIN rail; see Dimensions.
Heat Dissipation Considerations
For reliable operation, ensure that the operating specifications are not exceeded.The enclosure must provide adequate
heat dissipation, so that the air closely surrounding the Module does not exceed the maximum operating temperature
stated in the Specifications. Methods to reduce heat build-up include venting, forced airflow (e.g., exhaust fans),
adequate enclosure exterior surface area, and spacing between modules and other sources of heat.
WARNING . . . Shock Hazard
Always disconnect power from the Safety Module and all power from the machine being controlled before
making any connections or replacing any component. Electrical installation and wiring muct by made by
qualified personnel and must comply with the NEC (National Electrical Code), ANSI NFPA79 or IEC 60204-1, and
all applicable local standards and codes.
It is not possible to give exact wiring instructions for a Safety Module which interfaces to a multitude of machine
control configurations. The following guidelines are general in nature.
The Safety Module has no delay function. Its output relay contacts open within 25 milliseconds after a safety input
opens. This classifies the Safety Module as a functional stop "Category 0" E-stop control, as defined by ANSI NFPA
79 and IEC/EN 60204-1.
The Safety Module is powered by either a 12-24V dc supply at 4W or an ac supply (115V ac, model ES-UA-5A, or
230V ac, model ES-VA-5A) at 7VA. The safety inputs can be connected to:
A +24V dc source that is switched by a hard/relay contact in single-channel hookup configuration, or
Hard/relay contacts in a dual-channel hookup configuration using terminals S11-S12 and S21-S22.
