Safety Function: Hinge Switch 5
Rockwell Automation Publication SAFETY-AT096A-EN-P – November 2013
Functional Safety Description
Door Monitoring Function
When the door is opened, the hinge switch opens its two safety contacts. When the
hinge switch turns off, the Guardmaster dual-input safety relay (GSR DI) responds by
opening its safety contacts (13...14 and 23…24), de-energizing the coils of K1 and
K2. With power removed, hazardous motion coasts to a stop (Stop Category 0).
Hazardous motion cannot be started until the door is closed and the Reset button is
pressed and released.
E-stop Function
The pulsed outputs of the relay (terminals S11 and S21) are run separately through
the two E-stop contacts to the input terminals S12 and S22, respectively. When the
E-stop is pressed, these two circuits are interrupted. The relay responds to this
circuit interruption by opening its safety contacts (13…14 and 23…24), de-energizing
the coils of K1 and K2. With power removed, hazardous motion coasts to a stop
(Stop Category 0). Hazardous motion cannot be started until the E-stop is released
and the Reset button is pressed and released.
