Banner SI-HG63 Hinge Style Switches - Manual (Page 2)

NOTE: This symbol for a positive-opening safety contact (IEC 60947-5-1) is used in the switching dia-
gram to identify the point in actuator travel where the normally-closed safety contact is fully open.

Overview
Use the SI-HG(Z)63 series to monitor the position of a guard to detect the movement, opening, or removal. A "guard" can be a gate,
door, cover, panel, barrier or other physical means that separates an individual from a hazard. Safety interlock switches will issue a signal
to the machine control system to prevent or stop (halt) hazardous situations when the guard is not in the proper position. These safety
interlock switches are designed for non-locking guarding applications, unless another means of locking is provided.
Installation Requirements
The following general requirements and considerations apply to the installation of interlocked gates and guards for the purpose of safe-
guarding. In addition, the user must refer to the relevant regulations and comply with all necessary requirements. See ANSI B11.19, or
ISO 14119 and ISO 14120, or the appropriate standard.
Hazards guarded by the interlocked guard must be prevented from operating until the guard is closed; a stop command must be issued to
the guarded machine if the guard opens while the hazard is present. Closing the guard must not, by itself, initiate hazardous motion; a
separate procedure must be required to initiate the motion. The safety switches must not be used as a mechanical or end-of-travel stop.
Locate the guard an adequate distance from the danger zone (so the hazard has time to stop before the guard is opened sufficiently to
provide access to the hazard). The guard must open either laterally or away from the hazard, not into the safeguarded area. The guard
also should not be able to close by itself and activate the interlocking circuitry. The installation must prevent personnel from reaching
over, under, around or through the guard to access the hazard. Any openings in the guard must not allow access to the hazard—see
ANSI B11.19, ISO 13857, or the appropriate standard. The guard must be strong enough and designed to protect personnel and contain
hazards within the guarded area that can be ejected, dropped, or emitted by the machine.
Design and install the safety interlocking switches and actuators so that they cannot be easily defeated. Mount them securely so that their
physical position cannot shift, using reliable fasteners that require a tool to remove. Mounting slots in the housing, if provided, are for
initial adjustment only; final mounting holes (round) must be used for permanent location.
The normally closed safety contacts are of a "positive-opening" design. Positive-opening operation causes the contacts to be forced
open, without the use of springs, when the switch actuator is disengaged or moved from its home position. 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.
WARNING: Interlocked Guards
The user must refer to the relevant regulations and comply with all necessary requirements. See ANSI
B11.19, or ISO 14119 and ISO 14120, or the appropriate standard. At a minimum, the interlocked guard
must prevent hazards when not fully closed and must also prevent access to the hazards through any open-
ing in the guard. The safety interlocking switches and actuators must be designed and installed so that they
cannot be easily defeated, and are not used as a mechanical or end-of-travel stop. At least one switch must
be mounted in a positive mode and open the normally closed contact when the guard opens. Failure to
follow these guidelines may result in serious bodily injury or death.
