Chapter 9 Application and Wiring Examples
Figure 51 - EMD Safety Relay - On Delay
The EMD safety relay in Figure 52 is configured for a maximum of a 100 second jog. The single
wire safety signal from terminals L11 to L12 enables the EMD safety relay when the safety gate
is closed and the SI safety relay is reset. When enabled, press and hold closed the Jog switch
to turn on the EMD safety relay outputs. If the Jog button is released before the 100 second
time, the EMD safety relay outputs turn off. If the Jog button is held longer than 100 seconds,
the EMD safety relay outputs only turn on for 100 seconds.
For most applications, the jog switch can be connected directly to 24V through a normally
open switch or contact. A Form C contact can be used for improved noise immunity; connect
the normally closed contact to 0V.
