MAIN Relays K27A(NC), K27A and K27B change state when the system is turned on and remain latched while
the system is turned on. When the system is turned off, these relays revert to their normal state.
FUNC Relay K10 is an auxiliary relay that closes during the START / ON sequence and opens when PB1 and
PB2 are released.
For 9-36VDC power supply, wire #1 corresponds to the negative charge (-), wire #3 corresponds to the positive
charge (+), and wire #2 is for GROUND.
The circled numbers in the output diagrams above correspond to the wire numbers in the harness.
Suppressors are recommended on contactors being driven by Flex relays due to the possibility of voltage
spikes.
