1. 3 output relays per motion – shared 2nd speed output relay
Output relays with Forward 1st speed (F1), Reverse 1st speed (R1) and Forward/
Reverse 2nd speed (F/R2). Forward and Reverse 2nd speed (F/R2) share the same
output relay.
2. 4 output relays per motion – separate 1st and 2nd speed output relays
Output relays with Forward 1st speed (F1), Reverse 1st speed (R1), Forward 2nd
speed (F2) and Reverse 2nd speed (R2). Forward and Reverse 2nd speed with
separate output relays.
4.2.2.2 Output Relay Actions at 2nd Speed
1. 3 output relay configuration with Closed/Closed contact at 2nd speed*
