Safety Relays
Two styles of safety relays have been used on  Green-
smaster 3250−D machines. Later production machines
(after serial number 250000000) have a different relay
terminal arrangement than  relays on earlier machines
(Fig. 4). Relay operation is identical regardless of termi-
nal layout.
