4.2.2
Output Relay Configurations
4.2.2.1 Output Relay Types
1. 2 output relays per motion – single speed only
Output relays with Forward (F) and Reverse (R) 1st speed only.
2. 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) shared the same
output relay.
4.2.2.2 Output Relay Actions at 2nd Speed
3 output relays configuration with Closed/Closed contact at 2nd speed
F1 (or R1) output relay closed at 1st speed and F1 + F/R2 (or R1 + F/R2) output
relays closed at 2nd speed.
See Section 4.2.3.1 on page 29
on how to set to this
function.
4.2.2.3 START + AUX Function
After executing the START command at transmitter startup the
same START position becomes an auxiliary function with
momentary contact connected through the K10 Function
output relay. There are other types of auxiliary functions made
available for the K10 Function output relays (
see Section
4.2.5 on page 32
). Contact Magnetek field service if your
application requires other types of auxiliary functions
connected to the Function output relay.
