Banner ES-FA-6G Safety Module - Manual (Page 4)

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 complementary 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 information (such as GM-FA-10J p/n 60998, SI-
LS83/-LS100 p/n 59622, or SI-HG63 p/n 129465 datasheets).
Mechanical Installation
The 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. The Safety Module mounts directly to standard 35 mm DIN rail.
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.
Electrical Installation
WARNING: Shock Hazard and Hazardous Energy
Always disconnect power from the safety system (for example, device, module, interfacing, etc.)
and the machine being controlled before making any connections or replacing any component.
Electrical installation and wiring must be made by Qualified Personnel and must comply with the relevant
electrical standards and wiring codes, such as the NEC (National Electrical Code), ANSI NFPA79, or IEC
60204-1, and all applicable local standards and codes.
Lockout/tagout procedures may be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, ISO
14118, or the appropriate standard for controlling hazardous energy.
It is not possible to give exact wiring instructions for a Safety Module that 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" control, as defined by ANSI NFPA 79 and IEC/EN 60204-1.
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.
Safety Input Device Hookup Options
The operation of all dual-channel hookup options is concurrent, meaning that input channel 1 and input channel 2 must be in the same
state in both the STOP and RUN condition, but with no simultaneity (i.e. timing) requirement between the channels.
The dual-channel hookup configuration is able to detect certain failures and faults, such as short circuits, that could result in a loss of
the safety function. Once such a failure or fault is detected, the Safety Module will turn OFF (open) its safety outputs until the problem is
fixed. This circuit can meet ISO 13849-1 Category 2, 3, or 4 requirements, depending on the safety rating and the installation of the
safety input device. This circuit can detect a short circuit between channels or to another source of power, at a minimum, when the device
is actuated.
A single device with redundant outputs that can fail in such a manner to lose the safety function, such as a single safety interlocking
switch, can typically meet only a Category 2. See below for means to eliminate or minimize the possibility of failures and faults that could
result in the loss of the safety function(s).
The single-channel hookup configuration cannot detect short circuits to secondary sources of +24V dc or detect the loss of the switch-
ing function of the safety input device (i.e., it is not redundant) and thus this circuit typically can meet only ISO 13849-1 Category 2.
