Next Generation <strong>Guardmaster®</strong> <strong>Safety</strong> <strong>Relays</strong><br />
<strong>DI</strong>, <strong>DI</strong>S, <strong>and</strong> <strong>EM</strong><br />
E-stop, <strong>Safety</strong> Mat, Light Curtain <strong>and</strong> Interlock Switch, Monitored Manual Reset<br />
Here the <strong>DI</strong> to the left will AND the IN1 <strong>and</strong> IN2 inputs. The single-wire safety input is ignored. The <strong>DI</strong> on the right will AND IN1, IN2 <strong>and</strong> the<br />
single-wire safety input (L12). For the safety mat input, S11 is wired to S22 <strong>and</strong> S21 is wired to S12 (opposite of st<strong>and</strong>ard switch wiring) so<br />
the relay recognizes that a mat is wired to the input rather than a st<strong>and</strong>ard switch with a cross fault. If the E-stop or the OSSD devices are<br />
tripped all outputs on both relays will turn off. If the mat or interlock switch are tripped only the outputs to K3 <strong>and</strong> K4 will turn off.<br />
Two Dual-Channel E-stops to <strong>DI</strong> Connected to <strong>EM</strong> via Single-Wire <strong>Safety</strong> Connection, Manual Monitored Reset<br />
Here the <strong>DI</strong>S will AND IN1 <strong>and</strong> IN2 while ignoring the single-wire safety input. The single-wire safety output is driving the input of the<br />
expansion module (<strong>EM</strong>) while not using any of the st<strong>and</strong>ard outputs of the base device.<br />
