Overview
The GM-FA-10J Gate Monitor Safety Module (the “Safety Module”) is used to verify the proper operation of coded magnetic safety
switches and positive-opening safety switches by monitoring a normally open (N.O.) and a normally closed (N.C.) contact from each
switch. It can also be used to monitor and verify the correct state of two redundant current-sourcing PNP signals. (One PNP source must
be Normally OFF and the other Normally Conducting for each input channel.) In a typical application, two safety switches (individually
mounted) indicate the open or closed status of a gate, moveable guard, or barrier (all called “guards” throughout this document).
Two functions of the Safety Module are:
1. To monitor the contacts and wiring of safety switches for certain failures and to prevent the machine from restarting if the switch or
the Module fails, and
2. To provide a reset routine after closing the guard and returning the inputs to their “closed” condition. This reset function may be
required by machine safety standards.
The Safety Module monitors each switch for complementary switching; each channel must have one open (OFF) input and one closed
(conducting) input at all times. These inputs must always be in opposite states and must switch state within 1 second of each other.
Channel 1 has a “guard closed” condition when S11/S13 is closed and S11/S12 is open. Similarly, Channel 2 has a “guard closed” condi-
tion when S21/S23 is closed and S21/S22 is open (see
Figure 2. Wiring to two 4-wire coded magnetic safety switches
on page 7 and
Figure 3. Wiring to two positive-opening safety interlock switches
on page 7). The Safety Module also will detect and properly respond
to a short circuit between the channels and a short circuit to other sources of power. The Safety Module will open the safety outputs
within 35 milliseconds of the switching of either channel when the guard opens.
When the guard closes, debounce logic in the Safety Module’s inputs increases the reliability and repeatability of successfully resetting
the Safety Module and reduces the necessity of re-cycling the guard. This feature can result in increased efficiency of the machine, even
if the guard is misaligned or vibration is present.
