WARNING: Hazard Point
It must not be possible for personnel to reach any hazard point through an opened guard (or any
opening) before hazardous machine motion has completely stopped.
Please reference OSHA CFR 1910.217 and ANSI B11 standards for information on determining safety
distances and safe opening sizes for your guarding devices.
WARNING: Safety Categories
The level of safety circuit integrity can be greatly impacted by the design and installation of the safety
devices and the means of interfacing of those devices. A risk assessment must be performed to deter-
mine the appropriate safety circuit integrity level or safety category as described by ISO 13849-1
(EN 954-1) to ensure that the expected risk reduction is achieved and that all relevant regulations
and standards are complied with.
Safety Interlock Switch Requirements
The following general requirements and considerations apply to the installation of interlocked guards and gates for the purpose of safe-
guarding. In addition, the user must refer to the relevant regulations to be sure to comply with all necessary requirements.
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.
The guard must be located an adequate distance from the danger zone (so that the hazard has time to stop before the guard is opened
sufficiently to provide access to the hazard), and it 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. In addition, the installation must prevent personnel
from reaching over, under, around or through the guard to the hazard. Any openings in the guard must not allow access to the hazard

The Safety Module may be configured via DIP switches for two-channel (redundant
switches on a single guard), or one-channel operation (individual switches on two
S11
S13
guards). In two-channel operation, each channel must switch within 3-second si-
multaneity of the other when the guard closes. If not, the guard must be re-opened
23 Y1
and closed until the timing requirement is met. When the guard opens, the two
channels operate concurrently (both channels must switch, but without the timing
S11 S13
requirement).
23 Y1
In one-channel operation, each channel operates individually, except to reset the
K1
K2
device (in which case both guards must be closed). If only one switch is being
14 24
monitored, the closed input of the unused channel must be jumpered (S11/S13 or
Machine

S21/S23).
24 A2
S21 S22
The reset function has two options, selected by DIP switch: Automatic reset or
24 Monitored Manual reset. See
A2
9 for configuration information.
S22
S21
The reset input also can be used for an External Device Monitoring (EDM) circuit.
The EDM circuit consists of a normally closed, force-guided contact from each de-
vice being controlled by the Safety Module, all wired in series with the Reset button
(if used) and terminated at terminals Y1 and Y2. See
two-channel monitoring of multiple guards
The output of the Safety Module consists of two redundant output switching chan-
nels, each of which is the series connection of two forced-guided relay contacts
(K1 and K2 in
guards
up to 6 amps.
